Abstract

A method for coordinating testing of a wireless device under test (DUT) using non-link testing resources. Coordination between the tester and DUT is achieved by transmitting, from the tester to the DUT, predetermined numbers of data packets associated with predetermined tester identification data (e.g., MAC addresses identifying the tester transmitter). During test phases involving measurement and/or calibration of DUT transmit signals, the tester sends a number of data packets associated with one or more versions of tester identification data, in response to which the DUT performs internal operations (e.g., revising transmit power offsets). During later test phases involving validation of DUT performance, the tester sends another number of data packets associated with one or more versions of the tester identification data to inform the DUT that its testing has passed or failed, and/or is to be repeated.

First claim

What is claimed is:

1. A method for coordinating testing of a wireless device under test (DUT), comprising:
receiving, with said DUT during a first predetermined time interval, a first radio frequency (RF) data packet signal including first identification data corresponding to at least one of said DUT or a tester, wherein said first identification data comprises one of a MAC address or Bluetooth address for one of said DUT or said tester;
determining, with said DUT, a first number of data packets received during said first predetermined time interval in said first RF data packet signal; and
performing, with said DUT, a DUT operation corresponding to at least said first number of data packets and including at least one of transmitting a second RF data packet signal or receiving a third RF data packet signal.

2. A method for coordinating testing of a wireless device under test (DUT), comprising:
receiving, with said DUT during a first predetermined time interval, a first radio frequency (RF) data packet signal including first identification data corresponding to at least one of said DUT or a tester by decoding a portion of said first RF data packet signal including said first identification data to identify a wireless device address;
determining, with said DUT, a first number of data packets received during said first predetermined time interval in said first data packet signal; and
performing, with said DUT, a DUT operation corresponding to at least said first number of data packets and including at least one of transmitting a second RF data packet signal or receiving a third RF data packet signal.

3. A method for coordinating testing of a wireless device under test (DUT), comprising:
receiving, with said DUT during a first predetermined time interval, a first radio frequency (RF) data packet signal including first identification data corresponding to at least one of said DUT or a tester;
determining, with said DUT, a first number of data packets received during said first predetermined time interval in said first data packet signal; and
performing, with said DUT, a DUT operation corresponding to at least said first number of data packets by
performing at least one test of one or more operations of said DUT including at least one of transmitting a second RF data packet signal or receiving a third RF data packet signal, and
generating a plurality of test data corresponding to a result of said at least one test.

4. A method for coordinating testing of a wireless device under test (DUT), comprising:
receiving, with said DUT during a first predetermined time interval, a first radio frequency (RF) data packet signal including first identification data corresponding to at least one of said DUT or a tester;
determining, with said DUT, a first number of data packets received during said first predetermined time interval in said first data packet signal;
performing, with said DUT, a DUT operation corresponding to at least said first number of data packets and including at least one of transmitting a second RF data packet signal or receiving a third RF data packet signal;
receiving, with said DUT during a second predetermined time interval, a fourth RF data packet signal including second identification data corresponding to at least one of said DUT or said tester; and
determining, with said DUT, a second number of data packets received during said second predetermined time interval in said fourth data packet signal;
wherein said performing, with said DUT, a DUT operation corresponding to at least said first number of data packets comprises performing, with said DUT, a DUT operation corresponding to at least said first and second numbers of data packets and including at least one of transmitting a fifth RF data packet signal or receiving a sixth RF data packet signal.
