AT&T Network Systems, BELL ATLANTIC NYNEX Mobile, and PCSI Complete CDPD Specification 1.1 Field Trials Business Editors & Computer Writers.
The latest specification provides for improved CDPD systems performance and efficiency with the existing analog Advanced Mobile Phone Systems (AMPS). The field trials, conducted on BELL ATLANTIC NYNEX Mobile's system in Atlantic City, are a significant advancement in the deployment of CDPD networks nationwide.
CDPD is a packet data technology that builds on existing cellular infrastructure and enables mobile users to transmit data digitally at rates up to 19.2 kbps. CDPD works by transmitting data packets over existing cellular frequencies, making it a flexible and economical way to send and receive wireless data. CDPD adds packet data capability to cellular networks that already support circuit-switched data and voice. CDPD is currently available in 32 cities nationwide. Rand Baldwin, executive director for the CDPD Forum, commented on the specification 1.1 trials stating, "These trials underscore the industry's commitment to the rapid deployment of CDPD throughout the United States. CDPD's momentum is building, and these trials are excellent examples of how vendors, integrators and carriers are working together to bring the benefits of CDPD technology to users nationwide."
The field trials were conducted using both CDPD specification 1.1-compatible infrastructure and subscriber (end-user) products. Among the capabilities confirmed was the coexistence between CDPD and AMPS operations without any call interference. Additionally, the trials verified that CDPD coverage in each cell replicates the AMPS footprint.
AT&T Network Systems acted as the systems integrator, providing a complete CDPD specification 1.1 network using PCSI hardware and BELL ATLANTIC NYNEX Mobile cell sites for service. AT&T Network Systems was instrumental in supporting the entire field trials and ensuring network interoperability.
BELL ATLANTIC NYNEX Mobile plans to implement specification 1.1 to its CDPD systems this year while continuing the support of specification 1.0 customers for as long as necessary.
