TIA ANSI/TIA/EIA-136-270-C

This standard details definitions, methods of measurement, and minimum performance requirements for 800 MHz and 1900 MHz Wireless¹ mobile stations. Unless otherwise stated, the same requirements apply to both 800 MHz and 1900 MHz digital operation. These standards defined herein share the purpose of assuring that a mobile station can obtain service in any network that meets the compatibility requirements of TIA/EIA-136².

Compatibility, as used in connection with these standards and TIA/EIA-136, is understood to mean: Any mobile station is able to place and receive calls in any wireless system. Conversely, all wireless systems are able to place and receive calls with any mobile station.

These standards allow the minimum performance requirements of, Analog 800 MHz, Digital 800 MHz and Digital 1900 MHz equipment to be measured. This standard does not suggest or imply any dual mode or dual band equipment implementation requirements. It merely provides the test methodology for mobile equipment designed for use on wireless systems complying with TIA/EIA-136.

To assure compatibility, it is essential that both radio system parameters and call processing parameters be specified. The speech-filtering, modulation, and RF-emission parameters commonly encountered in analog cellular systems have been updated and expanded to reflect the unique radio plan upon which wireless systems are based. The sequence of call processing steps that the mobile station and base station execute to establish calls has been specified in TIA/EIA-136 along with the digital control messages and/or analog signals that are exchanged between the two stations.

A mobile station is intended to be used while in motion or during halts at unspecified points. It is assumed that mobile stations include portable units (e.g., hand-held "personal" units) as well as units installed in vehicles.

Although the basic purpose of wireless telecommunications has been voice communication, evolving usages (e.g., data) may allow the omission of some of the features specified herein provided that the system compatibility is not compromised.

These standards concentrate specifically on the mobile station; they cover the operation of the land station, the wireless switch, and the base station control equipment only to the extent that compatibility with TIA/EIA-136 is assured.

¹ In the context of this standard, wireless systems are taken to mean Cellular and PCS systems.
