Speeds up to Developed in the early s, CDPD was large on the horizon as a future technology. However, it had difficulty competing against existing slower but less expensive Mobitex and DataTac systems, and never quite gained widespread acceptance before newer, faster standards such as GPRS became dominant.

CDPD had very limited consumer products. It was one of the first products of wireless web service. Digital Ocean, Inc. A company named OmniSky provided service for Palm V devices. Omnisky OmniSky then file bankrupt in then was picked up by EarthLink Wireless the technician that developed the tech support for all of the wireless technology was a man by the name of Myron Feasel he was brought from company to company ending up at Palm.

PocketNet was generally considered a failure with competition from 2G services such as Sprint's Wireless Web. Despite its limited success as a consumer offering, CDPD was adopted in a number of enterprise and government networks. It was particularly popular as a first-generation wireless data solution for telemetry devices machine to machine communications and for public safety mobile data terminals.

Equipment for this service now has little to no residual value. Primary elements of a CDPD network are: 1. There are 2 kinds of End systems 1. Mobile end system : subscriber unit to access CDPD network over a wireless interface 2. There are 2 kinds of Intermediate systems 1. Generic intermediate system : simple router with no knowledge of mobility issues 2. It is a set of hardware and software functions that provide switching, accounting, registration, authentication, encryption, and so on. The design of CDPD was based on several design objectives that are often repeated in designing overlay networks or new networks.

A lot of emphasis was laid on open architectures and reusing as much of the existing RF infrastructure as possible. From Wikipedia, the free encyclopedia.
