This Standard details definitions, methods of measurement, and minimum performance characteristics for Code Division Multiple Access (CDMA) mobile stations. This Standard shares the purpose of  (and subsequent revision thereof) by ensuring that a mobile 6 station can obtain service in any cellular system that meets the compatibility requirements of .
Compatibility, as used in connection with this Standard and , is understood to mean that any mobile station is able to place and receive calls in any CDMA system. Conversely, all 10 CDMA systems are able to place and receive calls with any CDMA mobile station supporting 11 operation in the same band.
Test methods are recommended in this document; however, methods other than those recommended may suffice for the same purpose.
The performance metrics in this Standard require a mobile station to provide a single antenna connector for testing. Mobile stations having multiple antenna, such as for receive diversity, shall provide a single antenna connector for testing. If a mobile station has more than one antenna connector, only one connector shall be used for testing. Additional 18 requirements specifically for multiple antenna configurations, i.e. receive diversity, are for future study.
