Abstract :
The interference between first adjacent channels N and Nplusmn1 in an environment of distributed on-channel transmitters is analyzed. Channel N uses a single transmitter and the adjacent channels Nplusmn1 use distributed on-channel transmitters. The conditions and planning factors that will permit reliable implementation of ACI-free areas across all applicable signal levels are presented. The effect of antenna gain, height and power relative to the physical separation between channels N and Nplusmn1 are analyzed and the regions of adjacent channel interference (ACI) are delineated
