A standard testing signal is inputted in the multi-path environment.
When the level is set as the reference sensitivity level, the data
generated after modulation and channel encoding have the FER,
generated after modulation and channel encoding have the FER,
RBER or BER performance that can satisfy the requirements
specified.
Compliant with GSM 11.21 and GSM 05.05.

Compliant with GSM 11.21 and GSM 05.05.
iv. Referential interference level (interference and suppression of the
same frequency and adjacent channels).
The referential interference level means the capability that the
transmitter receives the expected modulation signal not over the
The referential interference level means the capability that the
transmitter receives the expected modulation signal not over the
given degraded quantity, which is caused by the unexpected
modulation signal on the same carrier frequency (inference of the
modulation signal on the same carrier frequency (inference of the
same channel) or any adjacent carrier frequency (inference of the
adjacent channel).
Compliant with GSM 11.21 and GSM 05.05.

Compliant with GSM 11.21 and GSM 05.05.
v. Block and spurious response suppression
The block and spurious response suppression is to test the
capability that the BSS transmitter receives the GSM modulation
signal when interferential signal exists.
Compliant with GSM 11.21 and GSM 05.05.
signal when interferential signal exists.
Compliant with GSM 11.21 and GSM 05.05.
vi. Inter-modulation suppression
This index is for measuring the linear degree of the RF part of the
transmitter. It indicates, when two or multiple unexpected signals
which are relative to the expected signal in frequency exist, the
transmitter. It indicates, when two or multiple unexpected signals
which are relative to the expected signal in frequency exist, the
transmitter’s capability of receiving the respected modulation signal
is not over the given degraded quantity.

Compliant with GSM 11.21 and GSM 05.05.
vii. AM suppression
AM suppression means the transmitter’s capability of receiving the
expected modulation signals is not over the given degraded
expected modulation signals is not over the given degraded
quantity when an unexpected modulation signal exists.

viii. Spurious emission
The spurious emission is the emission on the frequencies except
that of the RF channel of the transmitter and adjacent frequencies.
