January 2004 Stephen Berger, TEM Consulting Slide * Conclusion CTIA Over the Air Test Plan provides a repeatable measure of radiated performance of wireless devices. The results of this test are far better indicators of mobile station performance than current conducted power class measurements. Phones should be classified based on radiated performance, not conducted power. Near-field couplers and test boxes can be used in production environments to test entire radiated path when adjusting output power.

Created to provide the wireless industry with an unbiased, independent and centralized product evaluation service. 3-Part Evaluation Program 1. Testing to wireless industry technology platform standards. 2. Over-the-air performance tests. 3. FCC Type Acceptance Tests Certified products also required to contain information on driver safety, consumer safety, audio accessibility, and hands-free capability. CTIA Certification Program Working Group (CPWG) develops test requirements for parts 1 and 2. 1. CDMA, GSM, TDMA, and Analog test plans. 2. Over-the-Air Performance Test Plan (Antenna Test Plan). January 2004 Stephen Berger, TEM Consulting Slide * CTIA Status Manufacturers wishing to sell CTIA Certified mobile devices must perform all required tests. Some US wireless carriers have made CTIA Certification a requirement. Tests for Parts 1 and 2 must be performed at a CTIA Authorized Test Lab (CATL). CATLs are A2LA Accredited. Part 3 tests must be done by FCC authorized l
