It was one of the first products of wireless web service. It functions similar to Base Station.


In this technique CDPD mobile checks for flag bit in downlink channel which informs whether uplink slot is idle or busy. 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 endind up at Palm.

Communication between them occurs via MDBS. The net data rate is 9. Despite its limited success as a consumer offering, CDPD was adopted in a digitaal of enterprise and government networks.

In order to support packet data, CDPD has been introduced in Though it has its own infrastructure it utilizes vacant AMPS assigned channels or gaps between the channels for packet communication.
