With the trend of the evolution of Information and Communication Technology (ICT), high data rate transmission is expected and needed in the next generation mobile network. In order to maintain the same quality of service, the transmission power would need to be increased if the current mobile cellular network architecture is to be considered. To solve this problem, a multi-hop virtual cellular network (VCN) has been proposed. The simulation results of a resource allocation algorithm with interference for a parallel relay 2-hop OFDMA virtual cellular network have shown that the VCN can achieve a better channel capacity than the single hop network for low transmission power. In this paper, using this algorithm, we evaluate the channel capacity of the VCN as the number of users increases, and study the degree of fairness of the VCN compared with that of the conventional single hop network. For low transmission power, the simulation results show: a) the channel capacity of the VCN remains better than that of the single hop network as the number of users increases, and b) the VCN can achieve a better degree of fairness than the single hop network.
