The IBM/Motorola cellular computers actually use land mobile radio frequencies, of which Motorola owns several in almost every city worth transmitting to. They are 25kHz channels up around 900MHz, near the cellular band, and are normally used for dispatch services - e.g. plumbers and other businesses too small to have their own license and base station. There is a Motorola/Federal Express system that is similar to the IBM oine. The speeds used are comparable to voice-band modems. Peter Desnoyers
