CDPD presents new challenges for RF testing: Even when cellular channels are dedicated exclusively to use for cellular digital packet data (CDPD), RF performance tests should be conducted on the CDPD systems to assure that it is not degrading the AMPS sys

Published Tuesday, April 01, 1997

Even though cellular digital packet data (CDPD) service is generally overlaid on an existing advanced mobile phone service (AMPS) system, it still requires a battery of RF performance tests independent of those conducted to evaluate its AMPS counterpart. It is the complementary nature of CDPD that necessitates effective RF measurements, because the CDPD system has the potential to degrade AMPS system performance. Although these tests are not complex, they vary somewhat from those required to evaluate an AMPS system. Considerable attention has been paid to these RF measurements as more CDPD systems have been deployed, because CDPD performance ...
