Under typical urban fading conditions (i.e. multipath delays no greater than 5 µs), the quality threshold for full‑rate speech and PDTCH/CS-1 is reached at a C/I value of approximately 9 dB. The maximum sensitivity is approximately ‑104 dBm for base stations and GSM mobiles and ‑102 dBm for GSM small MSs and PCS 1900 MS s and ‑102 dBm for DCS 1 800 hand‑helds (see 3GPP TS 45.005).

For EC-GSM-IoT, the logical channels can operate in what is referred to as extended coverage. Under typical urban fading conditions, the maximum sensitivity when using the highest number of blind physical layer transmissions is reached at approximately -128 dBm for a base station and -118,5 dBm for an EC-GSM-IoT MS. The co-channel interference performance limit when using the highest number of blind physical layer transmissions is reached at approximately -14 dB for a base station and -10,5 dB for an EC-GSM-IoT MS (see 3GPP TS 45.005).

Multi band MSs shall meet the requirements on each band of operation respectively.
