Abstract
A channel emulator reads a record of captured radio signal data of a group of cellular base stations in a fielded cellular network from a memory. Based on the record of the captured radio signal data, the channel emulator generates a simulation of a radio environment of the fielded cellular network. In one aspect, the simulation generates a number of live cellular base station signals fewer than the group of cellular base stations in the fielded cellular network. In another aspect, a terrain environment model is applied based on the captured radio signal data.
