THOUGHT: Using EDGE and UMTS with Windows Mobile Pocket PCs

During last Fridays User Group meeting, we've also tested the EDGE capabilities of the HTC Hermes. To be honest - EDGE is pretty new for us Germans since T-Mobile has just started to roll-out EDGE in their network and T-Mobile is the only operator in Germany which is introducing EDGE at all. Neither Vodafone, nor E-Plus or O2 Germany have announced any plans to follow T-Mobile.
Thanks to my fellow User Group member Thomas, I was able to test EDGE in the T-Mobile network (since he provided the T-Mobile SIM) and while EDGE isn't implemented nation-wide yet, it looks like it is already implemented in Munich.

While GPRS (also called 2.5G) provides you a theoretical speed of 57 Kbps, EDGE (also called 2.75G) gives the GSM network a theoretical boost up to 220 Kbps. On the other hand, the 3G networks like UMTS provides a speed up to 384 Kbps boosted by HSDPA (3.5G) up to 1.8 Mbps!

With the HTC Hermes we archived in the EDGE network 160,3 Kbps and in the UMTS network 320,6 Kbps:

While T-Mobile has finalized its HSDPA rollout which is available in the whole T-Mobile UMTS network now, the ROM version I have on my test Hermes lacks support for HSDPA at the moment. Therefore we wasn't able to archive any better measurements than the UMTS figures.
Nevertheless, the EDGE speed is quite impressive, even if half of the UMTS speed only but - and that's the difference - EDGE will be available nationwide (since it uses the GSM network infrastructure) while the nationwide 3G rollout will takes several more years.

Hi Arne, my question is which US provider will be providing UMTS service (it almost seems like cingular only??). I'd really like to start making UMTS video calls on the Imate jasjar in the US smile

Lee, as you know I'm not an American and therefore my knowledge about the North American UMTS market is limited but AFAIK Cingular has HSDPA (UMTS 3.5G) in place already but it seems to work with 850/1900 MHz only, therefore you need a triband (UMTS 850/1900/2100 MHz) UMTS device like the HTC Hermes.
AFAIK also T-Mobile wants to launch UMTS in the States but as I've heard they haven't receive the frequencies they were bidding for last week at the FCC auction. Not sure which impact this will have on their launch plans.
