Spirent Communications plc has announced that the ETS-Lindgren's EMQuest antenna measurement software now supports Spirent's UMTS Location Test System (ULTS).

This new capability will enable wireless device manufacturers to quickly and easily add Spirent's A-GPS instrumentation to ETS-Lindgren's over the air (OTA) wireless test solutions, streamlining efforts to meet emerging standards for wireless device Assisted GPS (A-GPS) performance.

The combined offering of Spirent's A-GPS instrumentation and ETS-Lindgren's OTA test facilities, antennas, and EMQuest software provide wireless device manufacturers with the ability to test their products in compliance with the upcoming 3.0 release of the CTIA's test plan for mobile station OTA performance. The requirements of this new release will become mandatory at all CTIA authorized test labs that perform OTA testing.

"We are delighted that the Spirent ULTS solution is now supported by ETS-Lindgren. It is a natural step to link Spirent's market leadership in A-GPS testing with ETS-Lindgren's leadership in wireless OTA test solutions," said Ron Borsato, solutions architect at Spirent, who also chairs the CTIA's GPS OTA subgroup. "The large percentage of CTIA Authorized Test Labs that use ETS-Lindgren's OTA solutions for testing GSM and UMTS devices now have a straightforward upgrade path to add A-GPS OTA support."

Poor GPS antenna performance often leads to a disappointing user experience of location-based services, which can reflect negatively on operators' revenues. However, adding a GPS antenna to a densely-packed mobile device form factor can be a major challenge. Because the industry's existing certification standards for A-GPS do not include OTA testing, performance issues due to the GPS antenna are not always caught prior to commercial deployment. This has led the CTIA to broaden the scope of its existing test plan for mobile station OTA performance to include A-GPS.
