Bi-directional, compact, multi-path and free space channel replicator

摘要

An apparatus for simulating radio frequency (RF) signal propagation characteristics in a wireless communication network is disclosed. The apparatus includes a set of optical modulators in electrical communication with corresponding ones of a set of RF terminals. A set of optical demodulators is in optical communication with corresponding ones of the set of optical modulators and corresponding ones of the set of RF terminals. A set of optical delay lines may be configured to be in optical communication with the corresponding ones of the set of optical modulators and the corresponding ones of the set of optical demodulators.
