11.263GPPBase Station System (BSS) equipment specificationPart 4: RepeatersRelease 1997TS
A.2.1 Test purpose
To determine the net gain of the repeater outside its specified operating band (or bands), when this is less than a GSM band defined in subclause 4.1 of this ETS. The requirements of clause 7 of this ETS shall always be met, whether or not this test is also performed.
This test is not a normative requirement of this ETS.
A.2.2 Test case
The repeater shall be set to maximum gain. In case of a channel selective repeater, two of the channel selective modules shall be set to the lowermost and the uppermost ARFCN within the repeaters operating band.
A continuous sinusoidal RF signal shall be fed successively at each specified frequency into the relevant input port of the repeater. The power level of the RF input signal shall be at least 5 dB below the power level which would produce, when applied within the specified operating band, maximum rated output power, as declared by the manufacturer. This is to ensure that the equipment is operating in the linear output range.
The average output power in each case shall be measured and the net gain shall be recorded.
The measurements shall apply to all antenna ports of the repeater.
Test environment: Normal
A.2.3 Conformance requirement
At each frequency specified to be measured, the gain through the repeater shall be less than the specified value.
Annex B (informative): Change history
This annex lists all change requests approved for the present document since the first phase 2 version was approved by ETSI SMG.
