SAN DIEGO-An innovation in wireless data was announced last week that could answer CDPD’s main problem: coverage.
GTE Mobilnet Inc., Hughes Network Systems Inc. and Pacific Communications Sciences Inc. introduced Circuit Switched-Cellular Digital Packet Data, which will allow data users to access CDPD functionality across an entire network through circuit-switched or dial-up access. While CDPD’s coverage remains limited, users still can access CDPD’s functionality nationwide through this link. A modem bank behind a cellular switch converts an analog airlink into CDPD.
Starting today, GTE’s CS-CDPD solution is commercially available. Called Extended Wireless Packet Data, the service will be offered using handheld CDPD-compatible devices, like PCSI’s Personal Access Link, or PAL, superphone.
Hughes developed GTE’s CS-CDPD network system based on its modular GMH 2000 architecture, said the companies. The technology also is supported by Aether Technologies, Comcast Cellular Communications Inc., Lucent Technologies Inc., Mitsubishi Wireless Communications Inc. and Sierra Wireless.
Lucent’s Beverly Bach said CS-CDPD answers a chicken and egg problem. To increase CDPD coverage, more customers must adopt CDPD. But lack of coverage is what keeps potential customers from climbing aboard. Lucent is making infrastructure that supports CS-CDPD.
Sierra of Richmond, British Columbia, Canada, makes cellular data modems and said its MP200 Rugged Mobile modem now operates in CS-CDPD mode or in either mode individually.
