Over-the-air test solution delivered to 7 Layers

Spirent Communications has announced the first delivery of its over-the-air (OTA) test solution for assisted GPS (A-GPS) in mobile devices to 7 Layers in Irvine, California.

It is the first CTIA-accredited third-party laboratory to enlarge its OTA service portfolio with Spirent's UMTS location test system (ULTS).

Poor GPS antenna performance often leads to a disappointing user experience of location-based services, which can reflect negatively on revenues.

Adding a GPS antenna to a densely-packed mobile device form factor can be a major challenge.

As 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 OTA Performance Test Plan to include A-GPS.
