Abstract: Communication services have been the most intriguing things to network users in recent times. Hence there is the need to provide adequate communication facilities such as robust technologies in order to sustain the number of subscribers that are connected to wireless network daily. Therefore this paper provides the best platform to study the effect of ambient noise on wireless cellular network and how it affects the capacity and coverage of the cellular system. Special consideration is given to the Visafone CDMA network cellular environment of South-East Nigeria for the study from where the received signal levels from base stations are taken at various locations. The system is simulated using Matlab to give the vivid account of the effects of ambient noise within the cellular network and how it can be reduced. The simulation results show that at lower ambient noise, an advantage of a network capacity is achieved.
