7.3.1 CO-CHANNEL INTERFERENCE (C/I)
Cellular networks are more often limited by problem caused by interference rather by signal strength problems. Co-Channel interference is caused by the use of a frequency close to the exact same frequency. The former will interfere with the latter leading to the terms interfering frequency (I) and carrier frequency (C). The GSM specification recommends that the carrier to interference (C/I) ratio greater than 9 dB.
This C/I ratio is influenced by the following factors :
· The location of the MS
· Local geography and type of local scattersBTS antenna type, site elevation and position
