scope:

This Standard detai ls de finitions, methods of measurement, and minimum performance characteristics for access terminals. This Standard shares the purpose of UMB^{TM 1} ensuring that an access terminal can obtain service in any system that meets the compatibi lity requirements of UMB.

Compatibi lity, as used in connection with this Standard and UMB, is understood to mean that any access terminal is able to open data connections in any UMB system. Conversely, all UMB 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 speci fically for multiple antenna configurations, i .e. receive diversity, are for future study.
