scope:

The present document describes the technical characteristics and methods of testing the improved receiver performance for professional mobile stations (professional MS), base stations (BS) and repeaters for the Pan European digital cellular communications system and Personal Communication Systems (PCS) operating in the 900 MHz band (GSM 900), standardized by ETSI Special Mobile Group (SMG).

The present document is valid for equipment implemented according Phase2+ R99 onwards.

The present document covers the conformance testing of radio equipment supporting the extended frequency range ER-GSM. Equipment not supporting the extended frequency range ER-GSM is not covered in this document. It does not necessarily include all the characteristics which may be required by a user or subscriber, nor does it necessarily represent the optimum performance achievable. It should be noted that a receiver with improved parameters is specified in TS 102 933-1 [7]

The present document is part of the GSM-series of technical specifications. The present document neither replaces any of the other GSM technical specifications or GSM related ETSs or ENs, nor is it created to provide full understanding of (or parts of) the GSM 900 system. The present document lists the additional test procedures for testing the extended frequency band for ER-GSM.

For a full description of the system, reference should be made to all the GSM technical specifications or GSM related ETSs or ENs. Clause 2 provides a complete list of the GSM technical specifications, GSM related ETSs, ENs and ETRs, on which this conformance test specifications is based.

Equipment operating at the edge of the transmit and receive band might be subject to regulatory restrictions in some geographical regions. In areas where systems coexist the received interference power might have to be limited. Coexistence scenarios have been investigated in ECC Report 162 [i.2] providing also recommendations for the application of mitigation techniques.

The present document applies to the unit which includes the hardware to establish a connection across the radio interface.
