摘要

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.

主权项

1. A system, comprising:
a memory storing a record of captured radio signal data of a first plurality of cellular base stations in a fielded cellular network; and a channel emulator coupled to the memory, the channel emulator comprising one or more processors and accessing instructions executable by the processors including instructions that cause the channel emulator to:
read the record of captured radio signal data of the first plurality of cellular base stations in the fielded cellular network from the memory; andbased on the record of the captured radio signal data of the first plurality of cellular base stations in the fielded cellular network from the memory, generate a simulation of a radio environment of the fielded cellular network, the simulation generating a number of live cellular base station signals fewer than the first plurality of cellular base stations in the fielded cellular network.
