Spirent Communications, a leader in testing wireless networks, services and devices, recently announced immediate availability of the first commercialized test solution for LTE assisted GPS (A-GPS) Over-The Air (OTA) Testing. This is a co-development effort by Spirent and ETS-Lindgren, two leaders in location testing.
Brock Butler, Director of Wireless Location Technology for Spirent Communications was interviewed by GISCafe Voice about this important announcement:
1) What is LTE assisted GPS and why is it important?
Long Term Evolution (LTE), often called 4G, technology is being incorporated into many next-generation consumer devices, including smartphones. It enables voice and high speed wireless data services. Nearly all consumer devices migrating to LTE also have a strong need to provide positioning capabilities. The leading technology for positioning remains Global Navigation Satellite System (GNSS) such as GPS (United States satellite system) or GLONASS (Russian satellite system). Assisted GNSS (e.g. A-GPS) uses an assistance server to provide satellite information to the mobile device and when coupled to a cellular technology like LTE, A-GNSS can provide improved location performance by making position fixes faster particularly at the very low power levels often associated with consumer usage in urban and indoor environments.
