Cellular Digital Packet Data (CDPD) is a
specification for supporting wireless access to the internet and other
public data networks. CDPD transmits digital packet data at 19.2 Kbps,
using idle times between cellular voice calls on the cellular telephone
network. CDPD technology represent a way for law enforcement agencies
to improve how they manage their communications and information system.

data transmitted on the CDPD systems travel several times faster than
data send using analog networks.


CDPD is an overlay to the existing cellular network, which enables
users to transmit packets of data over the cellular network using a
portable computing device and a CDPD modem. CDPD offers a high-speed,
high-capacity, low-cost system with the greatest possible coverage.
Additionally data is encrypted for security. CDPD air link
transmissions have a 19,200 bps raw data rate. As a tool for
transmitting data CDPD utilizes digital networks.
