If you read my original article you'd see that I addressed this that
when they introduced GSM on cellular frequencies they decided for
whatever reason to call it GSM 850. The truth is that it uses the
same cellular frequencies used by analog AMPS, TDMA (IS-136) and CDMA.
Those claim to be on 800 Mhz when the truth is that no cellular or PCS
standard is exactly 800 or 1900 Mhz. They use one frequency to
transmit and one to receive. Those frequencies are *around* 800 or
1900 Mhz.
