With the huge growth in usage of Location-Based Services (LBS), 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. A-GNSS OTA testing gives a complete picture of real-world GNSS antenna performance and its impact on the end-user experience.
In February 2016, the CTIA expanded the OTA testing mandate scope to consider both GPS and GLONASS satellite constellations and require all location-enabled wireless devices—including laptops, tablets, and M2M devices, to undergo A-GNSS testing as part of the certification process.
Characterization and performance for both TDD-LTE and FDD-LTE devices

Test for CTIA mandates and operator-specific A-GNSS OTA performance requirements
A-GNSS OTA testing is performed in a controlled radiated environment and includes all relevant components (antennas, “phantom” head and hand, etc.). This ensures that all interaction factors between the radio and the rest of the wireless platform, including radiation pattern and platform interference, are taken into account when determining overall wireless performance.
