Future generations of cellular networks will have higher node density, larger number of antennas per node, and wider bandwidth.This paper develops capacity scaling laws for such networks by explicitly incorporating the impact of bandwidth on capacity.The main contribution is a capacity scaling upper bound for a cellular-type network architecture without base station cooperation.This upper bound is shown to be tight, as it provides the same scaling as an infrastructure multi-hop protocol introduced in previous work.The results show that large cellular networks transition from bandwidthlimited to power-limited capacities depending on the scaling of the bandwidth compared to the scaling of the number of nodes and that single hop protocols are suboptimal except when the bandwidth scaling is small.
