Short for Cellular Digital Packet Data, a data transmission technology developed for use on cellular phone frequencies. CDPD uses unused 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.
The Wireless Data Forum Web Site A not-for-profit industry assocation that promotes the advancement of open wireless data technologies and supports CDPD as an international standard for packet data transmission over a variety of networks and infrastructures.
