Registering with a Carrier

CDPD, short for Cellular Digital Packet Data, is also known as "Wireless IP".
It is a data transmission technology developed for use on cellular phone
frequencies. CDPD uses cellular channels (in the 800 to 900 MHz range) to
transmit data in packets. This technology offers data transfer rates of up to
19.2 Kbps, quicker call set up, and better error correction than using modems
on an analog cellular channel. CDPD is based on TCP/IP, the same protocols
that power the Internet. See the document
