We present an exact characterization of the 'capacity' of cellular wireless networks. Shannon capacity is intractable for most wireless networks, and a surrogate definition is used. The capacity is defined to be the largest ratio of the base-station density and the expected delay (number of retransmissions needed till success) seen at any mobile over all possible basestation strategies. This capacity definition captures the inherent practical aspects of wireless networks while still being analytically non-trivial. (Joint work with Srikanth Iyer at IISc, Bangalore)
