Patent ID: 8605604

Claim:
A network device comprising: a first wireless local-area network module configured to facilitate testing of a second wireless local-area network module, wherein the second wireless local-area network module is in a second device, and wherein the first wireless local-area network module comprises a receiver configured to (i) based on a first control signal transmitted from test equipment to the second wireless local-area network module, receive a first test signal transmitted from the second wireless local-area network module to the first wireless local-area network module, and (ii) receive a second control signal transmitted from the test equipment to the network device, a signal modifier configured to perform negative testing of the second wireless local-area network module including modifying the first test signal to stress test the second wireless local-area network module, wherein the signal modifier is configured to modify the first test signal to simulate errors in transmission of the first test signal between the first wireless local-area network module and the second wireless local-area network module, and wherein the modified first test signal is phase shifted from the first test signal received at the first wireless local-area network module, a transmitter, and a controller configured to provide the modified first test signal to the transmitter, wherein the transmitter is configured to, based on the second control signal, transmit the modified first test signal from the first wireless local-area network module back to the second wireless local-area network module.
