There have been a couple reports about T-Mobile’s HotSpot@Home service supporting data services through EDGE/GRPS only.
Those reports are WRONG!
What is being reported is that a “G” indicator on the display screen of the Nokia phone comes up when surfing/access packet services through UMA/Wi-Fi.
This actually means that the GRPS engine is being used, not that the GPRS/EGDE radio is being used. UMA is actually transporting the GRPS packet session over Wi-Fi.
This is actually the key advantage of UMA for packet services. If you start a data/packet session in UMA/Wi-Fi and then walk out the front door, that session will continue on the EDGE/GPRS network.
