Over-the-Air (OTA) Testing
OTA certification testing to ensure the accurate, repeatable, and uniform testing of Mobile Stations and Modular Devices. Certification testing to meet industry, carrier and/or CTIA standards.
Expanded Air Interface Testing Protocols Include:
Over-the-air measurements are performed by measuring the radiated transmit power at various locations surrounding the device to produce a spatially distributed three-dimensional characterization of the transmit performance of the EUT. The TRP is measured under Free-Space conditions, SAM Phantom Head conditions, Phantom Hand Only, and Head+Hand conditions, with the EUT antenna extended and retracted, as applicable.• Total Isotropic Sensitivity (TIS)
Sensitivity measurements are performed by determining the minimum forward-link power to maintain a specific error rate (FER, BER, BLER, PER, etc., depending on the air interface) at each measured location on the sphere in accordance with applicable industry standards. The TIS is measured under Free-Space conditions, SAM Phantom Head, Phantom Hand Only, and Head+Hand condtions, with the EUT antenna extended and retracted, as applicable.• GPS and aGPS Position Location Accuracy and Sensitivity
Testing is performed to determine the wireless devices ability to obtain GPS and aGPS signals. Conducted measurements are performed in addition to radiated OTA testing to measure the carrier-to-noise ratios along points of the major axis of the EUT. Testing is performed to determine the accuracy performance of the carrier network and the wireless test device as a system.• CTIA Test Plan for Mobile Station Over the Air Performance Ver-3.1
