What
is CDPD?
CDPD
(Cellular Digital Packet Data) is a specification for supporting wireless
access to the Internet and other public packet-switched networks. Cellular
telephone 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 adheres 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 IP protocol and
the ISO Connectionless Network Protocol (CLNP).
CDPD
also supports IP multicast (one-to-many) service. With multicast, a
company can periodically broadcast company 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.
What are the benefits of using Wireless Data?
· Speed
CDPD provides a raw data rate of 19.2 kbps, which is faster than any other
national wireless service offering available today.
· Open
Specification
Since CDPD is based on one of the most widely accepted networking
protocols, it provides unparalleled ease of use with existing IP-based
applications in a wireless environment. Additional software is also
available which optimizes the performance of the IP applications for CDPD
networks. This ensures economical wireless data transmissions via a CDPD
network.
· Reliability and
Security
CDPD packets use forward error correction methods that reduce the effects
of noise and interference on the airlink. CDPD also incorporates
authentication and encryption to all packet transmissions over the airlink.
With the use of standard network protocols, users can add
application-based end-to-end transmissions.
· Availability
Since CDPD utilizes existing cellular networks, carriers can deploy CDPD
services in a short period of time to meet customers' unique coverage
requirements. The base technology platform allows for easy integration
with existing applications, and a significant capability to provide
wireless Internet accessibility. This also means there are many companies
offering many hardware, software and network options.
· Cost
Effectiveness
When transmitting appropriately sized
data messages, CDPD can be substantially less expensive than making the
same connection during a data-over-cellular session.
