Wi-Fi Stays Strong

The EU recently finished a study of telecom in the EU27 countries. The full study is published here in PDF.

One interesting statistic is the penetration of Wi-Fi into households with internet access. Within the EU27, 46% of households with internet access have Wi-Fi. As one would expect, the number actually goes up to nearly half (48%) when looking at just the EU15.

Topping the list in terms of penetration is Spain (68%) and France (67%), with Luxembourg at the top with 75% of internet enabled households using Wi-Fi.

It’s no wonder that Berg Insight projected Wi-Fi in handsets to grow at a CAGR of 71% over the next four years. By 2012, Berg projects 400 million handsets with Wi-Fi. The primary drivers are high speed interent access in the home/office, and ‘connected home’ applications.

US Market Heats Up


If the rumors are true, things in the home zone market are about to get very interesting in the US.

Yesterday, there was a flurry of rumors that Sprint will launch their femtocell-based Airave service nationwide July 15th. The service has been in limited commercial trial for more than 6 months in the US.

Market watchers (like me) like to compare the service offers. According to the rumors Sprint will offer the Airave femtocell to subscribers for an upfront fee of $99 and $15/month (or $30/month for families). In return consumers get unlimited nationwide calling when attached to the femtocell, and improved coverage.

T-Mobile’s Wi-Fi based offer, HotSpot @Home, lets consumers use Wi-Fi access points already in the home or get new ‘optimized’ Wi-Fi routers from T-Mobile, which are free with a two year contract. Consumers can use Wi-Fi to improve coverage for their existing mobile plan. Or for an additional $10/month ($20/mos for families), subscribers can an add unlimited nationwide calling option when attached to Wi-Fi.

Interestingly, in a video interview from the Avren femtocell conference, Lauren Town, head of marketing at Orange for Wi-Fi-based home service Unik, noted that the value proposition articulated for femtocell home zones during the conference was nearly identical to their existing service.

It’s not clear if Sprint’s rate will come down to $10/month to match the T-Mobile offer. One clear advantage is that Sprint’s femtocell is 1xRTT (or ‘2G’ in CDMA parlance), which means that it will work with the entire installed base of Sprint handsets. T-Mobile's advantage? The service works on Wi-Fi anywhere in the world (enterprise, outside US,...) rather than just one femtocell.

Like many new offers, Sprint service has faced some growing pains during the initial trial phase. Presumably these issues have been worked out.

If anything, the pressure is increasing for AT&T and Verizon. Neither company has a ‘home zone’ offer, which means neither company has the ability to create a location specific service offer like ‘unlimited flat rate calling from home’.

PS – I just noticed this. The address used to be http://airave.sprint.com. But that address now redirects to http://www.sprintenterprise.com/airave/ Hummm…

An unlicensed femtocell

The market is catching on to the benefits of home zone services, where consumers get mobile services that work better and cost less. For operators, the ability to offload the macro network and increase the performance of mobile services indoors, coupled with the ability to develop location specific home or enterprise services has driven increased interest in this market opportunity.

Typically we talk about the need for home zone services, irrespective of the underlying radio technology (Wi-Fi or femtocell). For consumer and service providers, the benefits are nearly identical.

But an interesting trend has emerged in the press. Recently there have been several references to the ‘unlicensed femtocell’, perhaps known by the more common name of Wi-Fi.

The comparison makes sense. Femtocells have a couple of generic properties. One is a low power radio designed for use in-building CPE. Second is the ability for these devices to be deployed as consumer without operator intervention. Third, they are ‘self organizing’, meaning they determine their environment and adjust the capabilities accordingly. Forth, the term femtocell is actually radio agnostic. ‘Femtocell’ is applied to CDMA, UMTS, EV-DO, GSM, LTE, even WiMAX. While the one thing these have in common is that the frequencies are licensed, why not add 802.11 b/g to the list?

Now before you think this is something I made up, there have been several references of late:

This article in DigiTimes (“Tecom Ships UMA Femtocells”) refers to ‘UMA femtocells’ being shipped to T-Mobile. Clearly not the classic definition, these were in fact Wi-Fi terminal adaptors.

This article in The Register (“Femto Forum Gets Big Ideas”) comments that “In the USA T-Mobile is already deploying 2G femtocells to provide coverage in customers’ homes.” True, but it is an 802.11 b/g femtocell.

This last one is perhaps the most interesting. Ozzie Diaz, Chief Technologies for HP's wireless business, comments on his blog (“Wireless Operators Getting the Runaround”) about the importance of local radios:

One operator who does seem to have a clue on making use of these non-cellular radios in handsets is T-Mobile USA in their Hotspot@Home with unlimited calling while at home connected over their WiFi access point connected back to the T-Mobile core network. In essence a “femtocell” without the pain of the frequency planning or spectrum management. But taking the same advantage of femtocells and using the customers Internet access link at home for “free” backhaul to the core network…FABULOUS model of eliminating a BIG CAPEX problem for themselves.

It just gets you thinking about what a femtocell really is, a tool for making mobile services work better and cost less.

A Home Zone is a Home Zone

This week ABI Research released the results of a survey conducted on behalf of Motorola. The article states that while “…the majority of consumers have never heard of femtocells…”, “…more than 40% of European mobile and internet users plan to purchase femtocells in the next 12 months.”

It’s easy to conclude then, that the questions focused not on the wireless technology to be used in the home (e.g. a ‘femtocell’), but on the benefits of having a “Home Zone” service, where the key factors were better in-home mobile coverage and lower costs.

Demand was highest in Poland, Spain and Italy, with moderate demand in France and the UK. Germany had the lowest demand of the six countries surveyed.

We at UMA Today thought this sounded a bit familiar. Through the magic of the web, we were able to recall a similar announcement from Motorola in August, 2005. Three years ago, Motorola announced the results of a survey of 1,000 consumers in six countries on the demand for a dual-mode handset service. This time the countries were France, Germany, Spain, Sweden, Italy and the UK.

And the results??? About the same.

Demand was highest in Sweden, Spain and Italy, moderate demand in France, lower demand in the UK and Germany.

I think there are some very interesting data-points from both surveys:

  • Clearly there is continued demand for home zone services, regardless of the technology.
  • I find it ironic that Italy continues to show strong demand, showing me that Telecom Italia Mobile’s Unica service was a victim of regulatory roadblocks rather than consumer interest.
  • Orange’s plans for its Unik/Unique service are in UK, Spain, and Poland, three countries with strong demand for Home Zone services.

UMA Today continues to be a strong supporter of Home Zone services, and this is simply confirms that there is market demand from consumers for a thoughtful, value-oriented service offer.

The Mobile Operator's Triple Play

Mobile operators have had a unique influence on personal communications. The rise of mobile services has put a phone into nearly everyone’s hand. Yet as a network-based service, the mobile has been largely disconnected from our most personal location: the home.

Over the past few years, mobile service providers have started to reach into the home by acquiring broadband service providers. The attraction is easy to see. Consumers buy mobile, consumers buy broadband, why not get broadband service from your mobile provider?

In addition, Universal Mobile Access technologies enable mobile providers to deliver mobile services over the broadband network through Wi-Fi and femtocell radios in the home. This ‘double-play’ service opportunity is building, with operators trialing and deploying ‘Home Zone’ services in the market today.

But yesterday’s announcement of T-Mobile’s fixed line home service, a VoIP offer from a mobile provider, suddenly opens up the mobile operator’s triple play: mobile, broadband and fixed.

In all fairness, mobile operators have tried to offer fixed line VoIP services in the past. But rather than using the existing mobile voice switches (MSCs), mobile operators were forced to buy new VoIP switches. Because these switches were separate from the MSCs providing the mobile voice service, there was a ‘disconnect’ to the offer.

There was a significant amount of work to integrate the bill from the VoIP switch into the bill for the mobile switch (in some cases, consumers received two bills…). With a new switch, a different provisioning system needed to be established to enable the VoIP service. Because mobile calls are anchored on the MSC and calls on the fixed network are anchored on the VoIP switch, there is no easy way to provide combinational services like dual ring and single voice mail.

With the advent of the UMA terminal adaptor, now mobile operators can seamlessly integrate fixed line home phone service directly into their existing mobile switching infrastructure, billing and provisioning systems. Calls on the fixed line appear simply as a second line within a subscriber’s existing service.

The market is already on the trajectory of a “Home Zone Triple Play”. Clearly the Linksys product, which supports a UMA terminal adaptor and Wi-Fi, is ideal for an operator to bring together dual-mode service, home phone service and broadband.

Within the femtocell community, there is a tremendous push to move into integrated femtocell products. Many companies have announced ‘integrated’ femtocell platforms to support DSL, Wi-Fi, and fixed line VoIP.

Looks like mobile operators are starting to attack the home.

T-Mobile's Fixed-line Home Phone Service To Go Nationwide

The now re-named “T-Mobile @Home” fixed line VoIP service looks set for a nationwide launch. I’ll be heading to my local T-Mobile store this week to check it out.

The service, which has been in limited commercial release in Dallas and Seattle, looks to be an enormous success. The article states that a whopping “…45 percent of users of the service … switched from other mobile operators”. Unbelievable!!!!!!

The offer is an incredible value, so I guess it makes sense. T-Mobile @Home offers consumers unlimited flat rate calling for $10/month from their fixed phone line. Comcast, my cable company, keeps telling me I can get the same service for $40.

Britt Wehrman, director of product development for T-Mobile, explains that many households maintain a fixed line home phone for convenience and ease of use. This service is addressing the segment of the market

The “T-Mobile @Home” service is separate from T-Mobile’s dual-mode service “HotSpot @Home”.

If you recall on June 13th there was an article in DigiTimes titled “Tecom gears up shipments of UMA femtocell base stations”. The article goes on to estimate that Tecom will ship 1 million units by the end of 2008.

Clearly there was a typo with the title, as there are no femtocell deployments with these types of volumes anywhere in the world yet. However, it looks like the Tecom product could be at the heart of the T-Mobile @Home service. If T-Mobile (45% inbound churn) and Tecom (1 m units in 2008) are correct, this is going to be a huge success.

T-Mobile Expands


Today T-Mobile added the Nokia 6301 and Samsung T339 dual-mode phones to their line-up for the HotSpot @Home service.

With 8 HS@H phones available today, T-Mobile has most of the bases covered. The much anticipated HTC Shadow II will fill in the Windows Mobile 6.1 hole and round out the portfolio for T-Mobile.

Looks like T-Mobile will make good on their goal of adding ten new handsets this year.

iCall: Opportunity or Threat

A couple weeks ago there was news about a new application for the iPhone called iCall. In the clever video demo below, the founders describe iCall as an application for the iPhone which enables users to make calls for free over any Wi-Fi access point. The video how theiCall application works:

  1. User starts call on GSM
  2. User goes into Wi-Fi
  3. Phone detected/attaches to Wi-Fi
  4. iCall application asks the user if they would like to switch the call to Wi-Fi
  5. Phone switches networks

If it sounds a lot like a UMA-based dual-mode handset service, it is. The only difference between iCall and T-Mobile’s HotSpot @Home service is step 4: User intervention.





So, is this an opportunity or a threat for the mobile operator? (Ed note: UMA Today’s position is always from the viewpoint of the mobile operator, UMA is for mobile operators)

There is a threshold for subscribers between ‘actions’ and ‘cost’. At what point does a user change their actions to save on costs? (Ed note: Here in San Jose, it’s when gas hits $4.60/gallon...)

Will users actually stop a call, press a button, and switch it to Wi-Fi to save money?

Or would users rather have a call that automatically switches to Wi-Fi and saves money? If so, then T-Mobile, Rogers, Orange, Cincinnati Bell, Telia and others already have this covered.

The Connected Home Heats Up

Just in time for summer, there is a lot of activity in making the handset part of the Connected Home.

For those who don’t know, there is a vision of a connected home where devices develop an ad-hoc network and can communicate. Standardizing this has been the domain of UPnP and more recently DLNA.

While there are a growing number of devices (TVs, DVRs, Printers, …) which support Connected Home, the mobile phone has been consistently out of the picture. Now two different approaches are helping to pull the phone into the connection.

First is Nokia with the N95, using Wi-Fi as the transport to communication with other devices in the home.



But clearly there is only a small number of Wi-Fi enabled handsets, and so femtocell vendor ip.Access has put together his clever demonstration on how a 3G phone could be proxied into the connected home through a femtocell.



While there are some questions about how this works, it's a powerful vision of bringing mobile phones into the connected home.

The Rush to Support Iu-h

There has been a lot of fervor surrounding the 3GPP's activities to develop a new Home Node B (aka femtocell) standard.

I came across the blog post the other day with the clever title "Supporting Iu-h, why the rush?"

The author has a pretty good take on the situation.

RAN Gateway wins again

I have spent some time considering the pros and cons of the new 3GPP HNB femtocell architecture. It’s too early to call it a standard, but for now, the basic building blocks are in place for putting the spec together.

One of the fundamental building blocks of the HNB effort is a ‘RAN Gateway’ style architecture. In this case, the RAN gateway network element sits ‘parallel’ to an RNC or BSC, and connects into the mobile core network via existing, well defined circuit interfaces (Iu-CS) and packet interfaces (Iu-PS).

Operators evaluating femtocells and femto architectures immediately grasped the benefits of using a RAN gateway approach:

  • All existing circuit and packet services are supported through the femtocell access network as they are supported through the macro RAN network. This is because the RAN gateway uses the same service interfaces as the RNC.
  • A ‘RAN’ gateway is located in the RAN, with a clear demark point into the mobile core network. For operators, they did not need to change the MSC or the service core in any dramatic fashion.

For all the rhetoric and posturing around the benefits of SIP and IMS, operators quickly understood that the most pragmatic approach for femtocell service delivery was through a RAN gateway architecture. In fact, one of the things that the proposals from Huawei, NSN, Alcatel/Lucent and Kineto/NEC/Motorola (ie UMA/GAN) all had in common was a RAN gateway.

From a UMA perspective, one important outcome of the HNB specification is a validation of the RAN gateway architecture operators and vendors alike.

UMA/GAN is, of course, the original RAN gateway architecture.

I harken back to the early days of dual-mode handsets (DMH). The debate raged: IMS/SIP/VCC vs UMA/GAN. It’s taken 3 years for this to sort itself out in the market. Today, it’s clear that UMA/GAN and the RAN gateway architecture is the (only?) choice.

In the last 12 months, the debate started again, this time for femtocells. But just as quickly, a winner was declared: RAN gateway for HNB (a la GAN).

Softmobile client from Gemalto

A UMA-enabled softmobile client is an application which has been on the drawing board for some time. There has been interest, but it’s been slow in coming.

For those who don’t know, the UMA-enabled softmobile client is a mobile telephony interface application which runs on a laptop and connects to the mobile core network via UMA.

The application is ideal for operators to offer their subscribers another way to use their services, especially when traveling outside the home country. Typically when I travel to Europe, I connect my laptop at the hotel and fire up Skype. But if I were to have a softmobile client from my GSM provider T-Mobile, I could use it instead.

Back at MWC 08, technology supplier Vitendo announced they had developed a UMA-based soft mobile. In addition, Gemalto announced that Orange has selected their UpTEQ Smart Dongle. But the announcement said nothing about UMA.

Now on their web site, the UpTeq Smart Dongle lists support for UMA.

This week, Orange UK announced plans to ratchet up their services and alluded to, among other things, a “…new ‘totally connected’ product line – including laptops, to build on fixed and mobile broadband capabilities”

We’ll have to keep an eye out to see if Orange UK becomes the launch pad for the softmobile application.

3GPP Selects Femtocell Standard, and it’s not (exactly) UMA/GAN

It was announced by multiple sources this week that 3GPP selected a reference architecture for femtocell-to-core network connectivity. This isn’t the completed standard, but sets the framework for the 3GPP RAN 3 working group to develop a full specification. The plan of record, per the 3GPP, is for the full stage 2 and stage 3 documents to be completed by Dec 2008 (in Release 8).

As has also been point out recently, the existing 3GPP UMA/GAN specification was one of a few architectures being considered as the basis for a formal 3GPP femtocell standard. The net result is that the UMA/GAN standard, as is, was not chosen. Sad but true. In order to reach an industry consensus on a HNB architecture there was a measure of compromise from all the participating companies. That’s the nature of standards: compromise.

However, while the HNB reference architecture is not full UMA/GAN, it adopts a number of key principles first introduced in the 3GPP GAN standard. For example, at the highest level, it follows an access-based (rather than core-based) approach, leveraging the existing Iu-cs/Iu-ps interfaces into the core service network. It also identifies the use of a specific protocol for solving a number of challenges associated with the ad-hoc deployment of devices over the internet.

Frankly, while the UMA community would have been delighted if 3GPP had adopted GAN lock-stock-and barrel (as they say in the US) as the formal femtocell standard, the likelihood has always been low. Fortunately, the agreed femtocell architecture builds on several core principles of GAN, which will help accelerate the market.

ThinkFemtocell has a good breakdown of different elements of the work.

For at least a little while longer, UMA/GAN remains the only 3GPP standard which supports femtocells today...

Rogers Launches Pearl 8120

Rogers, the latest UMA-based dual-mode service provider, today launched the RIM Pearl 8120 handset in their portfolio. The UMA Pearl is currently available from Orange and T-Mobile as well. It's good to see Rogers expanding their handset portfolio.

Vodafone Station: Screaming for UMA

As you may have seen, Vodafone announced a new product called “Station”. The original announcement was a bit confusing, but now that the dust has settled, I think it’s becoming clear.

The Station, made by Huawei, is a broadband router/modem. It can use either the integrated ADSL2+ modem or HSPA (via an additional dongle/UBS) for backhaul on the WAN. On the LAN, the Station provides Wi-Fi.

The target is to provide Vodafone subscribers with a broadband WAN connection. The target audience is likely someone using the Voda HSPA network for laptop data access. When at home, the HSPA network may have in-building propagation issues and the throughput/data rate may be low. Enter the Station. Install the Station with your HSPA dongle/USB key near a window to get a strong HSPA signal from the macro network. Then the Station uses Wi-Fi to transmit that signal to the laptop when at home.

So what is the ADSL2+ modem for? Well presumably it is faster to use the fixed network. And while I’m just speculating, I’ll bet they don’t want people sitting in their homes streaming lots of data over the HSPA network. Therefore, to offload the macro network, it’s better to have users running over a fixed line DSL connection. So users can start with HSPA while their DSL line is being installed.

The last wacky part? The Station comes with an analog voice port (ATA). Apparently when using the HSPA dongle, the station provides voice services over via the circuit voice capabilities of HSPA. And given the dongle has a SIM, this is another phone number/service available.

What I don’t understand is when the user transfers to the fixed line DSL connection, what happens to the analog voice service? With no dongle, there’s no way to associate the Station with the Vodafone mobile core. Hummm…

So why is this screaming for UMA?

First, it’s providing Wi-Fi indoors, clearly idea for a dual-mode handset service, and when the service transitions to the ADSL network, even better. With UMA, Vodafone could have a real ‘home zone’ service.

Second, the ATA ports could simply run UMA for the terminal adaptor function. Now the ports would be live/available to the consumer when connected via HSPA and/or DSL. It wouldn’t matter.

As I was writing this, I found a comment on Om Malik’s blog from someone suggesting there was a big opportunity in Wireless WAN and Wireless LAN. But can they build a femtocell (3G LAN) that uses HSPA for the WAN connection? That seems like a lot of 3G in one box, but maybe it’s on the drawing board somewhere.

The 3G iPhone needs "...VoIP like T-Mobile..."

Dear Steve Jobs...

In an open video/letter to Apple, the Street's senior technology correspondent Gary Krakow makes a list of his requirements for the new 3G iPhone.

Top of the list: 3G (doesn't that go without saying?)
But #2 on the list: "...a VoIP feature like T-Mobile..."

I think he means UMA!





If there's a problem, here's the link:

Apples and Oranges

I do appreciate the quote in Strategy Analytic’s press release about their latest research on the Enterprise FMC Market. They said “UMA is here to stay”.

But after reading the release about the report, I’m left feeling they are comparing apples and oranges.

"SIP-based services will initially be implemented by large multinationals with the capacity to carry voice traffic on their private MPLS network. Consequently, SIP-based revenues will overtake UMA revenues toward the end of the forecast period. Moreover, Microsoft's UC (Unified Communications) solution, is also likely to see positive uptake as a business solution," commented Andrew Brown, Director for Wireless Enterprise Strategies.

There’s no doubt that enterprises will use SIP for IP telephony. IP-PBXs all run SIP. One of the fundamental advantages is that the calls can be carried between PBXs over the enterprise’s own private networks. But that’s an enterprise solution.

UMA is a technology for mobile operators, not enterprises. Certainly prosumers will use UMA in the enterprise, but IT departments can’t ‘deploy UMA’. And UMA was not designed to be carried through a private network.

So comparing UMA revenues with SIP revenues for Enterprise FMC doesn’t seem to be comparing like services.

There is no doubt that UMA will have an impact on the enterprise market, but it will be an FMS impact, migrating minutes from the fixed network/PBX to the mobile network.



RIM Redux

Following up from yesterday's post, I have now listened to all of Jim Balsillie’s comments during his presentation at RIM’s Capital Markets Day, May 12, 2008, I wanted to offer up some of his quotes.

I’ve tried not to take these comments too far out of context, but basically Mr. Balsillie is bullish on UMA. About 29 minutes into the presentation (slide 24), he talks of their UMA-enabled products:


“The Wi-Fi UMA is going remarkably well.”
“I’m hard pressed to not see this as inevitable, for most if not everyone.”
“This is happening and it’s happening fast”.

In his Q&A section (slide 33), a gentleman from Integral Capital Partners asks:

“Can you comment on the carrier’s adoption, or in some cases, the lack there of, of the UMA option?”

Mr. Balsillie: “I think it’s a fair comment. I think a lot of carriers were keen on it, some were less keen on it. It’s hard to find a carrier that isn’t keen on it now. Some saw it as a threat, I saw it as an enabler, an inevitability. In a sense, it’s hard to find a carrier that isn’t excited about it now. I think it’s just so compelling and so inevitable. It’s not going to take out the cell phone. It’s a complement.”


I couldn’t agree more.

RIM is BOLD with UMA

RIM’s presentation during their Capital Markets day (May 12, 2008) talked a bit about UMA. In the slide below, they indicate the new Bold device is part of their UMA portfolio. Sounds good to me.

Wi-Fi Battery Life: UMA Wins Again

Last month PC Magazine reviewed the RIM Blackberry 8820. The review was quite positive, but one thing which really jumped out at me was this paragraph (second to last in the article):

One area where the 8820 really excels is in endurance; it beats the Curve 8320, although the 8320's performance isn't shabby. On a cellular talk time rundown test, the 8820 lasted 11 hours and 29 minutes with the Wi-Fi and Bluetooth radios turned off. Over UMA and Wi-Fi, the phone ran for almost 14 hours on the same test. If you're tired of your cell phone's short battery life, this device should be on your short list.

Or as they state in the article:

  • Continuous talk time (cellular): 11 hours 29 minutes
  • Continuous talk time (Wi-Fi): 13 hours 55 minutes

An all too common complain about dual mode phones is that Wi-Fi = poor battery life. Yet in PC Magazine’s own test, talking over Wi-Fi/UMA resulted in a 20% improvement in talk time/performance.

The evidence continues to mount that those issues are a thing of the past. Companies that are serious about Wi-Fi in devices are optimizing the performance to meet and many times exceed the performance of GSM only.

Sorry Sprint

A very interesting opinion was posted to the GLG site the other day. Samual Greenholtz with Telecom Pragmatics opines that Sprint’s first choice for its home zone service was a dual-mode CDMA/Wi-Fi product. But lacking a DMH standard for CDMA networks, they were forced to settle for their second choice technology: femtocells.

With that, I say “Sorry Sprint”. It’s well known that there is no UMA/GAN for CDMA networks. With a 3GPP2 version of GAN, Sprint would have been free to choose dual-mode handsets, femtocells, terminal adaptors or even softmobile clients to run off their mobile network.

Is there an opportunity here?

Another fixed line operator drops mobile

Yesterday, the Embarq CFO said that the company may drop its wireless service in 2009, handing subscribers back to its MVNO partner Sprint.

Embarq is the spin-out of Sprint’s original fixed line business. As part of the deal, Embarq developed an MVNO relationship with its former parent.

Embarq was one of the first to develop a dual-mode CDMA/Wi-Fi service. The service was announced by former FMC technology provider NewStep Networks.

In the article, Embarq said their original target was for 1 million mobile subscribers, but had achieved just over 100,000. I can only imagine what fraction of those subscribers actually chose the NewStep/FMC service. Suffice it to say, it’s hard for fixed operators to sell mobile services in general, let alone dual-mode services.

I have written in the past about the problems with fixed line operators developing dual-mode services. The problems aren’t technical. It’s possible to make a phone hand-over between fixed and mobile networks.

The problem is that dual-mode services are fundamentally about Fixed-to-Mobile Substitution (FMS). Yet that’s exactly the opposite of what a fixed operator wants. Fixed operators need MFS solutions, or a way to put mobile minutes back onto the fixed network. That is contrary to what consumers expect today.

Dual-mode services from fixed operators are always going to be challenging.

Note: I found a link to this article from another FMC company focused on fixed line operators. I think this company is actually gone now too.

A New Thought On Femtocell Pricing

This week, analyst Danny Briere with Telechoice wrote an interesting piece for Telephony Online. The article was titled a rather depressing “Carrier Femtocell Pricing Doomed?

I don’t think so, and Mr. Briere offers some interesting thoughts on alternative methods of pricing femtocell services. He has two points which I’ll oversimplify here:

  • Separate the ‘coverage’ aspect of a femtocell from the ‘service’

The issue Mr. Briere has with Sprint’s Airave offer is that the consumer is required to purchase both ‘coverage’ and ‘service’ with the femtocell. A consumer wanting improved coverage must spend $50 and pay a recurring fee of $15/month. The same applies to a subscriber just interested in the flat rate calling plan. There’s no ability for Sprint to segment the subscriber benefit.

He contrasts this with T-Mobile’s Wi-Fi-based service where consumers can get ‘coverage’ by simply getting a dual-mode phone, no additional fees apply. Then if a consumer wants the flat rate calling ‘service’, they can spend an extra $10/month.

  • Don’t underestimate subscriber’s ability to pay for something they value (in this case, coverage).

I think the concept of offering the femtocell as a pure consumer product play is creative. If the consumer values coverage, they may be willing to pay to address this issue. The operator may choose to have the consumer pay full price for the femtocell, or elect to subsidize a portion of the femtocell for subscriber retention reasons. But for subscribers who are coverage challenged, this may work.

One could apply the handset subsidy approach. If you want to just by a handset, a consumer pays full price. But if you choose to sign up for a service plan and commitment, then the handset is deeply subsidized.

To be worked out is the secondary/after market usage of a femtocell. Will the consumer be able to use the femtocell with a new mobile provider? In the US, there is an immediate radio issue (GSM vs CDMA) which hampers the issue immediately.

The point is there are many ways to meet consumer need, and the femtocell market is just getting started.

Fierce Names Top 5 'Converged' Devices

FierceWireless released their list of top ‘converged’ devices. By converged I think they meant dual-mode devices, as each of the five devices on the list had Wi-Fi.

The list was:

  1. BlackBerry 8820
  2. BlackBerry 8320
  3. HTC Mogul
  4. HTC Tilt 8925
  5. iPhone

Interestingly, two of the five are UMA-enabled. Given HTC is rumored to be bringing out UMA-enabled devices shortly, there’s a chance that next year’s list will be 4 out of 5 UMA-enabled.

As for the iPhone supporting UMA, it has been rumored in the past. But UMA in handsets is typically driven by operator requirements. Orange and Rogers both support dual-mode UMA service. Orange and Rogers also both sell the iPhone. Interesting…

PS – credit where credit is due: The image is from Gizmodo. I think choosing Mr. ROGERS to hold the iPhone is brilliant.

PPS – according to Wikipedia, the Mr. Rogers show was first developed in Toronto for CBC, making the reference doubly brilliant.

UMA+LTE: It's all good

Recently there has been a flurry of activity around the next generation Radio Access Network (RAN) technology known at LTE. LTE is the ‘all IP’ access network for mobile service providers. With very high throughput (>100mbps) and very low latency (targeting 5msec), LTE is designed to a be a true wireless broadband access network.

With that in mind, people have started questioning UMA’s role in an LTE environment. While there are a lot issues still in flux (including LTE itself), and much work still to be done, what is clear is that the core drivers behind UMA in a 2G or 3G environment still apply in LTE.

Some people simplistically view UMA as redundant in an LTE environment because they both ‘deliver services over an IP access network.’ This view completely misses the value of UMA in a Home Zone 2.0 (femtocell or dual-mode handset) service deployment.

Operator deploying Home Zone 2.0 services in a 2G or 3G network are doing so for three reasons:

  • Create service zone unique from the macro network with the goal of offering differentiated services/billing based on location.
  • Offload the macro RAN, especially for very high speed, media rich audio and video application.
  • Improve the performance, coverage and throughput rate for mobile data services when indoors/in the home zone.

These same service drivers apply directly, and in some cases are even more relevant, to an LTE RAN:

  • Create a unique service zone (still a competitive advantage)
  • Offload the macro RAN (definitely for the projected data rates)
  • Improve coverage/performance (certainly if LTE is at 2 gHz or higher)

As the market evolves, UMA will continue to evolve as well. Just as UMA started as a 2G technology and evolved to support the 3G/Iu interfaces, UMA will continue to evolve into key solution in an LTE-enabled network.

Cisco to buy ip.Access? Better to wait...

The industry is buzzing today with the rumor that ip.Access has ‘won’ a contract with AT&T to supply femtocells. The reportedly $500,000,000 contract for 7,000,000 units gives you an ASP of $71.43/unit. Ouch.

What exactly did they win? The right to sell femtocells below cost to AT&T?

Frankly I think it's AT&T that is hoping Cisco buys ip.Access. At least Cisco can afford to lose money on every unit and ‘make it up in volume.’

The article notes that the contract calls for ip.Access to ‘eventually price the units at less than $100 apiece’. If half of the units are sold at $100 each, the other 50% need to be sold at $42.86 to get to an ASP of $71.43. Hummm… that’s probably why the article dryly notes the contract ‘could exceed $500m.’

My advice to Cisco: wait… buy ip.Access out of bankruptcy.

The best way to get costs down in the market: Open standards.

Is NSN looking to leave its femto 'partners' behind?

An article from DigiTimes today confirms that Nokia Siemens Networks is in talks with several Taiwan-based manufacturers over plans for joint production of femtocells.

NSN has already signed agreements with Ubiquisys, RadioFrame, Thomson and Airvana for femtocell access points. Yet the article quotes NSN general manager for Taiwan, Hong Kong and Macau Mike Wang, who confirms the company is now in talks with ‘other network equipment makers, including Gemtek Technology and Accton Technology.’

Why would NSN need to source their own femtocells? They have signed up four independent femtocell access point vendors. Why sign up Gemtek and Accton too?

Maybe NSN is getting ready to leave its partners behind.

[UPDATE: In feedback from this blog post, I received word that NSN is rumored to be courting femtocell silicon vendors directly, lending credibility to the idea that they are looking to develop their own femtocell.]

UMA: The reason behind the Orange/FT - TeliaSonera discussions

Early last week rumors began circulating that Orange/France Telecom may be interested in acquiring TeliaSonera. An article in the International Herald Tribune provided an analysis, but left an odd question unanswered at the end of the article:

“Why would France Telecom possibly want to make [another] European acquisition?”

As the article points out, there’s little geographic overlap, the logic for incumbents merging is ‘muddled’, and its outside France Telecom’s stated goals.

Finally on Friday, things began to clear up. France Telecom Finance Director Gervais Pellissier said that acquiring TeliaSonera could give FT the scale it needs to counter future competitive threats from companies such as Google and/or Apple.

“How do you expect us to develop the LiveBox if we don’t have several million customers using it? How can we push UMA if we don’t have that power?” asked Mr. Pellissier.

Great question! Pushing UMA is a TOP priority for Orange/FT right now and clearly it’s viewed as a technical competitive advantage. UMA gives Orange an advantage in its “Home Zone 2.0” strategy.

Dreaming of dual-mode and UMA

It's good to know I'm not alone in the world. There are other technology geeks who dream about cool new stuff.

Check out the post: http://livebolt.com/blog/2008/04/17/visions-of-uma-danced-in-their-heads/

I have similar dreams about UMA and dual-mode services. In my case, I actually use the HotSpot @Home service. I agree that not everyone has signed up with T-Mobile... yet.

A Good Week For Handsets (and it's only Wednesday!)

T-Mobile is starting to make good on their promise to bring 10 new HotSpot @Home handsets to market in 2008. Heck, two hit the rumor mill this week alone!

First is the new Samsung T339, a feature-rich mid-tier handset which continues to push Samsung into the upper echelons of DMH supplier.

Second, a rumor broke on HTC’s Shadow II (shown), the appropriately named follow-on to the Shadow currently available from T-Mobile. This is notable for being the first Windows Mobile device with UMA available from T-Mobile.

All this happens in the same week that the UMA-enabled Blackberry Pearl shows up on the shelves of T-Mobile stores nationwide.

T-Mobile is definitely on a roll.

I-WLAN: RIP?

It came to my attention just recently that a key proponent of the 3GPP Interworked Wireless LAN (I-WLAN) specification has passed.

I-WLAN is a 3GPP specification designed to enable ‘nomadic’ devices (e.g. laptops) to access services in the mobile core network over a Wi-Fi/IP connection.

I-WLAN provides a secure connection and authentication mechanism which is similar to UMA. The fundamental difference between I-WLAN and UMA is that I-WLAN lacks mobility for sessions whereas UMA provides seamless mobility for circuit and packet services between IP (Wi-Fi) and GSM networks.

Azaire Networks (www.azairenet.com) disappeared at the end of March, just before the CTIA show. While the I-WLAN specification will live on in the 3GPP, it is likely to become one of the hundreds (?) of specifications which are developed but never achieve any commercial success in the public network.

It’s not enough to have a good idea, technology needs to solve a fundamental business problem. UMA lets mobile operators extend their voice and data services over the low cost, high performance IP access network, and create Home Zone 2.0 services. UMA’s continued success is a direct correlation to demand from service providers.

Internet Offload and UMA

“Internet Offload” is the ability for a dual-mode phone to connect directly to the internet through the Wi-Fi radio. The phone which comes to most people’s mind is the iPhone, but Wi-Fi enabled HTC and Nokia E/N series support this feature too.

When the iPhone enters a Wi-Fi environment, the GSM radio stays on (for circuit voice and mobile packet data services), and the Wi-Fi radio can be used for accessing internet services like Google Maps directly.

For some reason, the market seems to think that a dual-mode phone can support either UMA or Internet Offload, but not both simultaneously.

This is not true!

Internet Offload and UMA are fully compatible functions of a dual-mode phone.

In fact the strongest example is the family of UMA-enabled Blackberries (8820, Curve/8320, Pearl/8120) which all support UMA and Internet Offload concurrently.

Here’s how it works:

When a UMA-enabled Blackberry enters Wi-Fi, the UMA tunnel is established. The UMA tunnel is used to transport services which reside in the mobile core network to the phone. The easiest example is voice services. But any data application which is delivered from the mobile core is accessed through the UMA tunnel, applications like MMS or any stream media services offered from the network (MobiTV,…)

A key advantage of using the UMA tunnel for service delivery is mobility. Any application or service which takes advantage of the UMA tunnel maintains session continuity between the Wi-Fi network and the outdoor macro network.

But it’s the way UMA-enabled Blackberries also support Internet Offload which is most interesting. When the phone tries to access web based services like Google Maps, the traffic is routed directly to the Wi-Fi access layer and out to the internet. No going through the UMA tunnel, no burdening the mobile core with non-revenue generating internet traffic. Note this is also how the Blackberry accesses mail services when in Wi-Fi, directly over the internet.

The trick is that the Blackberry maintains a basic router function in the handset. For application which are ‘hosted’ (circuit voice, SMS, MMS,…), the traffic is routed through the UMA tunnel and to the mobile core. For browser based applications, the traffic is routed directly to the internet.

Note there is no 'seamless mobility' for services routed via Internet Offload directly over Wi-Fi. When the phone moves outside of Wi-Fi coverage, the session ends. The session can be restarted over the macro RAN, but there will be a drop in service.

Why is Internet Offload + UMA important?

First, it’s important to clear up the misunderstanding in the industry. Early UMA phones didn’t support the Internet Offload feature because operators specified they wanted UMA-enabled dual-mode phones to work ‘exactly the same’ in Wi-Fi as in GSM. Therefore, all the packet traffic was to be routed via the UMA tunnel to the mobile core when on Wi-Fi, because all packet traffic is routed to the mobile core when on GSM. [It’s in this way that UMA is really a RAN technology, making Wi-Fi an access radio for mobile services.]

With dual-mode phones supporting Internet Offload on the market, operators are again saying they want UMA-enabled phones to operate ‘exactly the same’. But now this means adding support for Internet Offload concurrently with UMA by routing some traffic over the UMA tunnel and other traffic directly to the internet.

Second, support of Internet Offload is a critical component of making the mobile phone an integral member of the ‘connected home.’ There is a movement underway to bring household electronics together into a cohesive fabric. But a mobile phone without Internet Offload capabilities* will be excluded from supporting local connections in the home. Thus the phone will continue to be outside the ‘connected home’ vision.

By highlighting UMA and Internet Offload support concurrently in the same device, UMA devices can now easily fit into the vision of the ‘connected home’.

Now Nokia N series handsets can support UMA along with the existing Internet Offload capabilities. In fact, the Nokia N95 was one of the first handsets to demonstrate support for DLNA, a ‘connected home’ protocol standard.

[* - There are two ways to make the handset a member of the 'connected home'. First is to have a dual-mode Wi-Fi enabled handset with Internet Offload capabilities. The second, pioneered by the Femto Forum, is to proxy a standard 3G handset into the connected home network via a femtocell.]

Still on track for 5.5 million

My favorite pessimistic telecom commentator, Dean Bubley, has recently recapped his outlook on network evolution in his 500th blog post.

Given his general skepticism regarding UMA as a viable technology for dual-mode handset services, I suppose I’m honored that UMA was listed as the very first item he chose to list as ‘over-hyped’.

[Side note: considering UMAToday is the only site ‘hyping’ UMA, I hardly consider it ‘over’-hyped, certainly when compared with other things on the list like WiMAX. But I’ll take that as a compliment that we’re doing something right, thanks Dean.]

But given the comments, I think Dean's jumping the gun a bit:

UMA (unlicenced mobile access) - well, it still hasn't got much traction after another 30 months. Maybe 1.5m subscribers at Orange & T-Mobile US, plus some hopefulness around femtocells. My original forecasts (considered horribly pessimistic at the time) of 5.5m UMA homes at end-2009 now actually look insufficiently pessimistic after all.

First, the comment ‘after another 30 months’ seems a bit odd. Orange only launched 18 months ago (October 2006), and T-mobile just 9 months ago (June 2007). True, we’ve been talking about dual-mode services and UMA for some time, but there hasn’t even been one 30 month period, let alone ‘another’.

But second, I think the forecast Dean made relating to UMA-based dual-mode handsets might actually be one he gets right*. I happen to believe 5m units is within range for 2008. At the end of his prediction period (YE 09), I suspect there will be well over 10m units sold, easily meeting his prediction of 5.5m homes by YE 09.

Thanks for the vote of confidence Dean!


[* Dean is a big fan of the ‘naked SIP’ handset revolution, suggesting that this is the way, rather than UMA, that the market will embrace dual-mode services and VoIP.

In this model, subscribers buy/acquire a Nokia E or N series phone and download a third party SIP client onto the handset. The idea is to bypass those nasty mobile operators and make calls for ‘free’. It's the TruPhone model. Of course, there are several reasons why this won’t work:

  1. Spending $500 on a handset to make cheap calls doesn’t compute. Anyone shelling out $500 for a phone isn’t so concerned about saving pennies on phone calls that they’ll download a second client onto a phone.
  2. Putting a second client and a second phone number (the SIP service) on a handset is a hassle. Consumers and prosumers want a single number that’s available all the time, not just when the handset is connected to Wi-Fi.
  3. Oh, you want to run this SIP client over the 3G network as well as Wi-Fi? Round trip latencies for today’s 3G access network are 200 msec, and that’s just ‘your side’ of the call. It does not take into account the rest of distance those packets must travel. That’s an unacceptable delay for voice calls, even free.

For some reason, Dean’s prediction of 220m ‘naked SIP’ phones shipped in 2008 wasn’t captured in his list of ‘over-hyped’ technologies. I don’t honestly know how many ‘naked SIP’ phones shipped, let alone how many are actually use the application he describes. But I'm willing to guess it's a lot less than 22o million.]

Is 3x Enough?

There is still some misunderstanding on the benefits of dual-mode handsets and home zone services. Operators are struggling to find services which offer some type of benefit, either increasing ARPU or reducing churn. I’m not sure what the market expects, but I think a service that reduces churn by 3x is not bad.

According to a slide deck used in France Telecom’s Investor Days (December, 2007):

“Homes equipped with UNIK churn 3 times less on their mobile contract than others” [slide 20, file: 5-France.pdf]

Is there any other service that reduces churn by 3x? Note this claim is from the actual operator who is realizing the benefit. It is unfiltered, unbiased, and objective information.

Maybe just keeping subscribers on your network isn’t enough...

How about a service that causes new subscribers to churn to your network? In today’s hyper-competitive market, subscriber numbers are a zero sum game, for you to win, someone needs to be losing.

T-Mobile recently announced that nearly 50% of the users taking their HotSpot @Home service are new to the operator.

Frankly that’s a staggering statistic. People are churning to T-Mobile to get a dual-mode handset service. To put it into perspective, an early article on AT&T about the iPhone said that “roughly 40% of iPhone subscribers were new AT&T customers.”

So DMH out-churns the iPhone!?!?! Crazy.

I know iPhone and HotSpot@Home are different, but both are bringing new subscribers to the operator’s network. I haven’t seen churn numbers on the iPhone, presumably because the users are still locked into their 2 year contracts, but 3x reduction on DMH services isn’t bad.

I guess the point of this post is: If you don’t have a UMA-based dual-mode handset service to sell, maybe the iPhone is the next best thing?
