Re: Cellular Bands
Cellular band is around 800/850 MHz. PCS band is around 1900 MHz. Lower frequencies generally travel farther and penetrate objects better, so cellular has a theoretical advantage there.
However, all wireless networks are designed with such factors in mind. PCS networks generally have more towers, spaced closer, to compensate for the reduced "reach". So in the end, there shouldn't be much difference between a properly-designed PCS network and a properly-designed Cellular network.
Another difference is the licensing. For any given geographic area in the U.S., there are six PCS licenses, but only two Cellular licenses.
That's why Sprint and T-Mobile have PCS-only networks - it's simply the only spectrum that was available when they got started. The Cellular licenses are usually taken by two of: Verizon Wireless, Cingular, and AT&T Wireless. Whichever of the three doesn't have a Cellular license, uses PCS in that area.
