The expanding vision for location-based services (LBS) is driving the need for solutions that enable mobile operators and device manufacturers to test location features on devices in real-world conditions. To that end, Spirent Communications has added what it describes as carrier-approved Assisted Global Navigation Satellite System (A-GNSS) record-and-playback capabilities to its Hybrid Location Technology Solution (HLTS).
The new capability records GNSS signals in the field and delivers synchronized assistance data over a radio access interface for testing of the A-GNSS positioning performance of mobile devices in a lab environment.
"With user location playing a key role in most smartphone services and applications, A-GNSS positioning performance greatly influences the end-user experience," said Nigel Wright, Sprirent's vice president of wireless. He added that accurately testing this technology using real-world field conditions helps ensure high quality LBS and emergency service performance.
A-GNSS uses an assistance server to provide satellite information to a mobile device. Combining GNSS signals from multiple satellite positioning systems (such as GPS and GLONASS) with assistance data delivered by the network to the device, A-GNSS is regarded as the most universal and precise positioning technology, Spirent said.
