Good info, from the trenches, but are you doing this with GPRS? BTW You made a good point on the software radios. Reading the articles on them, you would think it solves everything. Still need the RF stuff to send and receive the dinkytrons to/from free space. Also, rather than viewing the US spectrum as a "mess", I suggest you view it as the result of a technology advanced nation that optimized the use of the spectrum based on the then current "state of the art" using algorithms that were optimal at that time. Now the spectrum is fairly full up to some pretty frequency high limits. I did spend some time years ago looking for the space to put some new gear. Checking from DC to light revealed very few RF holes, certainly nothing nation wide and in a bandwidth to suit WCDMA. There was a large amount of spectrum set aside many decades ago for UHF TV. Very few users, mainly some small population centers (1000 people or so) that would install the necessary equipment in a small building on a mountain top (6000 to 8000 feet) that had a clear view to a large population center (10,000 people or so), and convert the channel 2 to 7 to the UHF band. Lots of little Blonder Tongue converter boxes with 6AF4s to convert it back to channel 3. Maintenance was done in the summer when the snow was gone. Failures in the winter months gave a result of "SOL", a highly technical term, until the snow melted. UHF band is now viewed as suitable for 3G WCDMA. So when Vodkafone tells it's US sub Variable Horizons to bend over and go to WCDMA, they will have to have some multi-multi band phone to roam to Euro land. BTW, hear first hand that Euro roaming with a GSM phone is not all peaches and cream.
