Rx Level Access Min Parameter in GSM

                               Rx Level Access Min

RxLevAccessMin = Mobile Sensitivity + Body loss + Multipath loss + Interference Margin

Mobile Sensitivity = -104 for GSM900 and -102 for DCS1800

Body loss = 3 dB recommended by ETSI and 5 dB recommended for GSM 900

                 =  3 dB recommended by ETSI and 3 dB recommended for DCS 1800

Multi path loss = Signal loss from base station due to reflection by buildings,etc before reaching mobile.                              

Normally the Multi path loss is around 3 dB but can be overcome by Antenna Diversity which has gain around 3 dB too.  (Space diversity = 3 dB,  90 degrees polarized diversity = 3 dB, 45 degrees slant polarized  diversity = 4.5 dB).

Interference Margin = Margin allocated to overcome C/I and C/N, the recommended value is 2 dB.

RxLevAccessMin = Mobile Sensitivity + Body loss + Multipath loss + Interference Margin

RxLevAccessMin = -104 + 3 + 0 + 2 (for GSM 900 with ETSI standard)                              = - 99 dBm

RxLevAccessMin = -104 + 5 + 0 + 2 (for GSM 900 with Ericsson standard)                              = - 97 dBm

RxLevAccessMin = -104 + 3 + 0 + 2 (for DCS 1800)                              = - 99 dBm
