GSM 1800 Half rate speech
The reference sensitivity performance in terms of frame erasure, bit error, or residual bit error rates (whichever is
appropriate) is specified in the following table, according to the propagation conditions.
Blocking:
Measurement Conditions:
Wanted carrier is 3dB above reference sensitivity.
Interferer is CW
Spurious response exceptions:
6 exceptions are permitted IN band 915 - 980MHz
24 exceptions are permitted OUTSIDE band 915 - 980MHz.
