Abstract

A system and method for initiating testing of a plurality of communication devices. The tester and devices under test (DUTs) are first synchronized as a way of confirming test readiness on the part of the DUTs, Following that, a test sequence is initiated by the tester. The synchronization and test initiation can be accomplished using signals with differing signal magnitudes or device identifiers. The test sequence can be a DUT transmit signal test in which each DUT transmits data packets in accordance with one or more predefined test sequences. Alternatively, the test sequence can be a DUT receive signal test in which the tester transmits data packets to the DUTs with differing signal frequencies or signal magnitudes.

Dependent claims

A method of initiating testing of a plurality of communication devices, comprising:

transmitting, with a tester, a plurality of synchronization initiation messages;
listening, with said tester, for one or more synchronization confirmation messages;
if said tester fails to receive a plurality of synchronization confirmation messages corresponding to said plurality of synchronization initiation messages, then
transmitting again, with said tester, said plurality of synchronization initiation messages,
listening again, with said tester, for one or more synchronization confirmation messages, and
repeating said transmitting again and said listening again until said tester has received a plurality of synchronization confirmation messages corresponding to said plurality of synchronization initiation messages;
following reception by said tester of said corresponding plurality of synchronization confirmation messages, transmitting, with said tester, a plurality of test initiation messages;
and
listening, with said tester, for one or more test confirmation messages.

A method of initiating testing of a plurality of communication devices, comprising:

listening, with a plurality of devices under test (DUTs), for a plurality of synchronization initiation messages;
transmitting, with each one of said plurality of DUTs that received one of said plurality of synchronization initiation messages, a respective one of a plurality of synchronization confirmation messages corresponding to said one of said plurality of synchronization initiation messages;
if one or more of said plurality of DUTs fails to receive one of said plurality of synchronization initiation messages, then listening again, with at least each one of said one or more of said plurality of DUTs, for at least a portion of said plurality of synchronization initiation messages;
following reception, by each one of said one or more of said plurality of DUTs, of at least one of said at least a portion of said plurality of synchronization initiation messages, transmitting, with each one of said one or more of said plurality of DUTs, a respective one of at least a portion of said plurality of synchronization confirmation messages corresponding to said at least a portion of said plurality of synchronization initiation messages;
listening, with said plurality of DUTs, for a plurality of test initiation messages;
and
transmitting, with each one of said plurality of DUTs that received one of said plurality of test initiation messages, a respective one of a plurality of test confirmation messages.
