Definition
(Context: General)
Cellular Digital Packet Data, or as it’s more commonly called, CDPD, consists of using cellular radio repeaters for the transmission of small bursts of data known as packets. The CDPD process allows the insertion of packets of data in between lightly modulated cellular radio voice channels without reducing cell phone voice capabilities. CDPD is an open transmission methodology for sending data on existing Advanced Mobile Phone Service (AMPS) cellular networks at a transmission rate of 19.2 kilobits per second. The network architecture uses the protocol used in the Internet (i.e., Transmission Control Protocol/Internet Protocol, or TCP/IP).
