Abstract: This application relates to apparatus and methods for testing the wireless functionality of a plurality of devices under test. In one example, a testing system includes a testing frame with multiple radio frequency (RF) shielded cabinets. Each of the RF shielded cabinets may house an antenna and a device under test. In addition, an electrical circuit couples a wireless simulation system to the antennas. The electrical circuit includes an RF combiner configured to combine two cellular signals from the wireless simulation system to output a combined cellular signal. The electrical circuit also includes an amplifier configured to receive the combined cellular signal and output an amplified cellular signal. Further, the electrical circuit includes an RF splitter configured to receive the amplified cellular signal and provide the amplified cellular signal to each of the plurality of antennas located within the RF shielded cabinets of the testing system.

Abstract: A remote radio head unit tester and a method for testing a remote radio head unit is shown and described. The remote radio head tester includes a chamber having an interior volume. The chamber encloses electrical components, at least one of the electrical components is a computer which has a testing algorithm installed thereon. A frame secured to the chamber. At least one set of wires operably coupled with the electrical components. The remote radio head unit tester is configured to test a remote radio head unit by booting up the remote radio head unit. The remote radio head unit can only be booted up after the correct power cables and data cables have been connected to the remote radio head unit. Checking the software version of the remote radio head unit and updating the software. Testing the power connections of the remote radio head unit.
