CDPD (Cellular Digital Packet Data)
Note: Many topics at this site are reduced versions of the text in "The Encyclopedia of Networking and Telecommunications." Search results will not be as extensive as a search of the book's CD-ROM.
CDPD (Cellular Digital Packet Data) provides packet-switching data services on wireless analog cellular systems such as AMPS. CDPD is sometimes called wireless IP, although that term now means much more, as discussed under the "Wireless IP". CDPD handles the types of bursty traffic that are common with network-connected users, such as short exchanges of information like electronic mail or database queries. Data is sent in packets across a wireless circuit that is shared by other users, or across any channel that is idle. Users are billed in subminute billing units to accommodate short data bursts. For more information, see "Wireless Mobile Communications."
