Abstract

A hardware architecture for a universal testing system used for performing Wifi tests on wireless devices under test (DUT) is disclosed. According to certain embodiments, test information travels from a Wifi port of the test server to the Wifi port'"'"'s antenna in a Faraday cage, and then travels over the air to DUT'"'"'s Wifi antenna in the same Faraday cage, and then to a LAN Ethernet port of the DUT, and then to the test server'"'"'s Ethernet port.

Claims

1. A test system for simultaneously and independently testing a plurality of wireless devices under test, the test system comprising:

a test controller for managing user interfaces associated with the test system;

a test server connected to the test controller; and

a plurality of faraday cages, each faraday cage of the plurality of faraday cages configured to receive a wireless device under test of a plurality of wireless devices under test and having associated with it a set of ports for connecting a faraday cage to a wireless device under test associated with the faraday cage and to the test server, each set of ports comprising;

a wireless port associated with an antenna internal to the faraday cage and connected to a wireless port on the test server, the wireless port on the test server being associated with a virtualization container for running wireless tests,

a radio frequency port associated with a radio frequency port on an associated wireless device under test, and

a networking port associated with a networking port on the associated wireless device under test and connected to a networking port on the test server, the networking port on the test server being associated with a virtualization container for running networking tests,

wherein the test controller employs web sockets to communicate with the test server such that the plurality of devices under test may be tested simultaneously and independently of each other and that the communication between the user interfaces and the test server is real-time, bidirectional, and asynchronous.

2. The test system of claim 1, further comprising:

a Multimedia Over Coax Alliance (MoCA) Wide Area Network (WAN) harness associated with a networking port on the test server,

a MoCA Local Areas Network (LAN) harness associated with a networking port on the test server,

a splitter connected to the MoCA WAN harness, the MoCA LAN harness, and the radio frequency port on the faraday cage.

3. The test system of claim 1, wherein the radio frequency port on the associated wireless device under test comprises a coaxial cable connector.

4. The test system of claim 1, wherein each of the networking ports comprises an Ethernet port.

5. The test system of claim 1, further comprising:

at least one user interface device in communication with the test controller.

6. The test system of claim 1, wherein a wireless signal test path is from the wireless port on the test server to the wireless port on the Faraday cage to the antenna internal to the Faraday cage to an antenna of the wireless device under test to the networking port of the wireless device under test to the networking port of the test server.
