My supervisor and others in my group were trying to >figure it out. Digital signals have a greater tolerance to interference than their analog counterpart. So, the required carrier to interference ratio (C/I) can be lower than the 18 dB required for analog cellular. This allows closer spacing between co-channel cell sites, and then increased user density and frequency reuse. More details are given in: W. C.
