Antenna Performance for Location-Based Services

A Spirent White Paper

White paper cover

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.

Read Spirent’s White Paper, A-GNSS Over-the-Air Performance Test Methodology: Antenna Performance for Location-Based Services, to learn more about:

  • Key test areas that characterize A-GNSS antenna performance
  • Specialized equipment and setup required for comprehensive lab testing

In February 2016, CTIA mandated Version 3.5.2 of its Test Plan for Wireless Device Over-the-Air (OTA) Performance. For more information particular to the CTIA standard, reference Spirent’s White Paper, A-GNSS Over-the-Air Performance Test Methodology: CTIA Test Plans and Their Implications.
