摘要： Method for testing one or more of a group of radio frequency (RF) data packet signal transceiver devices under test (DUTs) with reduced signal interference from the remaining DUTs. A tester broadcasts a signal containing power control instructions about uplink signal power characteristics for communication with the tester. For example, for the LTE 3GPP standards, such characteristics could include power ramping step size, preamble initial received target power or maximum number of preamble transmissions for uplink signals transmitted from the DUTs. Following initiation of communication between the tester and one or more DUTs, the tester broadcasts a signal containing power control instructions to instruct the remaining DUTs to transmit any future signals with different uplink signal power characteristics. For the LTE 3GPP standards, such different characteristics could include reduced power ramping step size, reduced preamble initial received target power or reduced maximum number of preamble transmissions for uplink signals.

摘要： A method for wireless communications testing using downlink (DL) signal transmissions from an access point to a mobile terminal and uplink (UL) signal transmissions from said mobile terminal to said access point. Accurate block error rate (BLER) testing of LTE mobile devices in a wireless signal environment is enabled by preventing repeated transmissions of the same downlink (DL) data block that would normally follow reception of uplink (UL) transmissions of negative UL acknowledgments (NACKs) caused by failures to decode prior DL data transmissions, thereby producing cumulative NACK counts accurately reflecting data reception errors.

摘要： Method for calibrating an over-the air (OTA) test system for testing multiple radio frequency (RF) data packet signal transceiver devices under test (DUTs), as well as using such a calibrated OTA test system for performing such tests. Calibration is achieved by placing a known good device (KGD) in multiple defined locations within the OTA test system, radiating the KGD with RF test signals at each location, and collecting from the KGD at each location channel quality information identifying optimal RF test signal sub-band channels for ensuring reliable communications within the test system. Use of such system includes placing multiple DUTs at the defined locations within the OTA test system and communicating with them wirelessly via the identified optimal RF test signal sub-band channels.
