A-GNSS Over-the-Air Performance Test Methodology


Antenna Performance for Location-Based Services

sc-AGNSS-OTA_Antenna_Performance_for_LBS

With the growth in usage of Location-Based Services (LBS) and the need to meet E911 requirements, the number of wireless devices supporting Assisted Global Navigation Satellite System (A-GNSS) is steadily on the rise.

As one of the enabling LBS technologies, A-GNSS offers its customers higher position accuracy, quicker location fixes, and improved coverage of service in difficult locations, such as urban environments. As a result, mobile operators and device manufacturers are looking for testing choices that quantify and benchmark real-world device performance.

The goal of Over-the-Air (OTA) testing is to obtain a “snapshot” of the performance of the device-under-test in all directions around the device. OTA testing includes all relevant components (antennas, “phantom” head and hand, etc.) in an isolation chamber to give a complete picture of real-world antenna performance and its impact on the end-user experience of LBS applications.
