Long Term Evolution (LTE) is one of the standards in 4G cellular technologies which offers different peakdata rates for voice, video, messaging traffic and other services. The Orthogonal Frequency Division Multiple Access(OFDMA) is a well applicable multiple access scheme of 4G-LTE cellular technology for supporting variable bit rateservices. OFDMA-based cellular communication network faces challenges in providing excellent Quality of Service(QoS) to the users. In order to provide good QoS, network operators have to make effective use of their availableresources, which leads to effective network design and planning. Capacity is one of the significant parameters indetermining the performance of any cellular communication system and it is also used for effective network design andplanning. However, the interference limits the capacity of cellular systems. Co-Channel Interference (CCI) is the majorsource of interference which is an important limiting factor for estimating the Erlang capacity in cellular systems . Inthis paper, an analytical method is proposed to evaluate the Erlang capacity of 4G-LTE cellular systems under CCI.Here the probability of CCI is considered for capacity determination. Erlang capacity results are evaluated for adifferent number of co-channel interferers, various spectral efficiencies, voice activity factors and various data rates.
