Abstract
A test system for testing an antenna of user equipment includes a channel emulator, an anechoic chamber, a base station emulator and a test control computer. The channel emulator supports bi-directional channel emulation and emulates wireless channel conditions with fading and without fading. The anechoic chamber is connected to the channel emulator and contains probes as well as user equipment as a device under test. The base station emulator is connected to the channel emulator and performs protocol testing with the device under test via the channel emulator without fading. The test control computer controls the other element of the test system along with a base station that is connected to the channel emulator and that performs performance testing with the device under test via the channel emulator with fading after the protocol testing is performed without fading.
