CDPD Connectivity

4.1 CDPD Overview

Cellular Digital Packet Data (CDPD) is an open system deﬁnition that uses digital

transmission on analog cellular (AMPS) channels to provide mobile packet-switched

data services.

The purpose of CDPD is to provide mobile access to the services available through

standard connectionless data protocols such as IP. CDPD could be considered to be a

wireless extension to the Internet that is available anywhere.

You can ﬁnd a fair amount of information about CDPD from the following sources:
