Cellular Digital Packet Data Seminar report







Cellular Digital Packet Data is a specification for supporting wireless access to the Internet and other public packet-switched networks. Data transmitted on the CDPD systems travel several times faster than data send using analog networks. Cellular telephones and modem providers that offer CDPD support make it possible for mobile users to get access to the Internet at up to 19.2 Kbps. Because CDPD is an open specification that remains to the layered structure of the Open Systems Interconnection (OSI) model, it has the ability to be extended in the future. CDPD supports both the Internet's Connectionless Network Protocol (CLNP). CDPD also supports IP multicast (one-to-many) service. With multicast, a company can periodically broadcast updates to sales and service people on the road or a news subscription service can transmit its issues as they are published. It will also support the next level of IP, IPV6. With CDPD we can assigned our very own address. With this address, we can virtually always connected to our host without having to keep a constant connection.
