1. A wireless packet data communications modem, comprising:
- a transceiver having a control input, a modulator for impressing modulation on a radio frequency carrier, and a demodulator for providing a demodulated data signal;
a logic unit, coupled to said modulator, said demodulator, said control input, and a controller interface physically couplable to a computer, said logic unit operating as a data interface between said controller interface and said transceiver; and
a housing for containment of said wireless packet data communications modem, said housing and said controller interface conforming at least in part to the Personal Computer Memory Card International Association Type II standard,wherein said modem is operable to send and receive messages through said transceiver when physically associated with said computer and when physically disassociated from said computer.
