Abstract
Cellular digital packet data (CDPD) systems borrow idle radio channels from Advanced Mobile Phone Standard (AMPS) cellular networks to send short bursts of packet data traffic. Unless AMPS channels are dedicated to CDPD, utilization of unused AMPS channels results in increased interference for voice. We quantify this increase in interference and show that in many systems the interference "slack" from the radio engineering in AMPS can be exploited to deploy CDPD on channels shared with voice. In particular, we find that this is true for 3-sector cells with 7-cell reuse, a deployment scheme used in many cellular systems.Keywords
