This Standard details definitions@ methods of measurement@ and minimum performance characteristics for access terminals. This Standard shares the purpose of [1] by ensuring that an access terminal can obtain service in any system that meets the compatibility requirements of [1]. Compatibility@ as used in connection with this Standard and [1]@ is understood to mean that any access terminal is able to open data connections in any xHRPD system. Conversely@ all xHRPD systems are able to open connections with any access terminal. 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 an access terminal to provide a single antenna connector for testing. Access terminals having multiple antenna@ such as for receive diversity@ shall provide a single antenna connector for testing. If an access terminal has more than one antenna connector@ only one connector shall be used for testing. Additional requirements specifically for multiple antenna configurations@ i.e. receive diversity@ are for future study.
