4.2. Rx Characteristics

4.2.1. Sensitivity

E-GSM 900 Full 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.

Channels

TCH/FS FER Class lb (RBER) Class ll (RBER)

The reference sensitivity level is < -102 dBm. NOTE: 1 < _ < 1.6. The value of a can be different for each channel condition but must remain the

same for FER and class 1b RBER measurements for the same channel condition.
