The mobile has to be able to receive data in the presence of power in an adjacent timeslot not intended for the mobile. In this case, the standards specify that the mobile must be able to cope with a difference in power levels between the timeslots of up to 6 dB, without degradation of performance. The mobile has to receive data in an adjacent timeslot intended for it as well as the timeslot in question. The mobile is also required to receive data when there is power in adjacent timeslots with respect to the following two situations: GSM 450, GSM480, GSM750, GSM850 and PGSM class 4 or 5 (small) MS: +2 dBĭCS1800 class 3 and PCS1900 class 1 or 2 MS: +2 dB The input levels provided in the above table are referenced to a normal PGSM mobile (MS), and must be corrected by the following values for other MS: Reference level under static conditions (dBm) The BLER in each case must be less than or equal to 10%. The following table shows the reference sensitivity input levels for GPRS mobiles in the various bands under static conditions. The Release 99 GSM 5.05 standard defines the reference sensitivity of GPRS mobiles. Standards Definition for Reference Sensitivity
