Are You Ready to Meet the New CTIA Version 3.0 Over the Air Test Plan?

Cedar Park, Texas – July 13, 2009 — ETS-Lindgren announced an integrated solution that lets wireless device manufacturers test their products for compliance with the new requirement from CTIA – The Wireless Association® for over the air performance testing of Assisted-GPS (A-GPS) enabled mobile devices. With the release of Version 3.0 of the CTIA's Test Plan for Mobile Station Over the Air Performance, this requirement will become mandatory for certification testing at all CTIA authorized test laboratories (CATLs).

ETS-Lindgren's integrated solution expands the company's AMS-8000 series of antenna measurement systems to support fully automated A-GPS receiver performance testing per CTIA's new test plan. For convenience, instrumentation options are also available to support A-GPS testing of GSM/UMTS and/or CDMA devices.

“Basically, we've developed upgrade pathways for the AMS-8000 series so our existing customers can easily modify the system to now perform over the air performance testing of A-GPS enabled mobile devices,” said Jari Vikstedt, Principal RF Engineer with ETS-Lindgren. “We're also happy to share our expertise with customers. We can quote our services for complete audit assistance for obtaining CATL status, including operating procedures and measurement uncertainty documents. We can perform a trial audit for a customer to assess their performance and correct any deficiencies prior to a final audit. Because of our detailed knowledge of the test plan, we can quickly bring existing and new customers up to speed to meet the new CTIA Version 3.0 test plan,” he added.

The AMS-8000 series systems include a fully anechoic radio frequency (RF) test chamber equipped with device under test (DUT) positioning equipment, antennas, instrumentation, and test automation software. Version 1.07 of ETS-Lindgren's EMQuest™ EMQ-100 Antenna Measurement Software adds support for A-GPS and other RSS based measurement methods. The system supports wireless communication test instrumentation from most leading suppliers as well as other third party communication test equipment through the use of plug-in drivers.

ETS-Lindgren has been manufacturing antennas and antenna measurement systems since the 1960’s. In 2000, ETS-Lindgren began developing systems for wireless over the air performance testing. In 2002, ETS-Lindgren became the first CTIA Authorized Test Lab (CATL) for Mobile Station Over the Air (OTA) Performance Testing. Since then, ETS-Lindgren has supplied the OTA systems for over 80% of all CATLs. The company has also developed the Radiated Performance Test (RPT) systems used by the majority of WiMAX Forum® certification laboratories worldwide.
