UMA/GAN standards adds Iu-mode (3G) support

At last week’s 3GPP meeting in Vancouver, the GERAN working group approved the CR (change request) that adds Iu-mode support to the UMA/GAN Stage 2 specification.

The addition of Iu-mode support to the UMA/GAN specification now also enables the development of UMA-enabled devices (dual-mode handsets, femtocells) that can leverage the 3G (Iu-CS/Iu-PS) interfaces into the core mobile network.

UMA started as a 2G technology and now supports both native 3G and 2G interfaces. The standard continues to evolve with mobile RAN.
