Abstract
Method for testing a radio frequency (RF) data packet signal transceiver device under test (DUT) via a wireless signal medium that enables final functional testing of a fully assembled DUT without requiring wired signal connections. System performance characteristics indicative of manufacturing assembly defects, such as defective antennas or subsystem connections, can be performed using over the air (OTA) test signals communicated wirelessly between the DUT and a tester. By using actual DUT performance characteristics determined during earlier manufacturing tests, such as receiver sensitivity and transmitter power, and known power levels available from the tester transmitter, the OTA signal path loss (i.e., attenuation of the wireless signal) can be estimated and used to confirm the final state of system operation.
