1)Mobile station’s output power in watts and in db.
2)Beamwidth of GSM and MW antenna.
Waiting for reply and would be thankful.

MS o/p pwr is 0.125 watt or 21 dbm

for all link budgeting purposes we take mobile o/p power as 2W,and BW of antenna is normally variable and normal antennas used are of BW-65deg,and 90deg.HORIZONTAL,7 deg.-VERTICAL respectively,gain around 17 dbi and it is also variable.I hv no idea about MW antenna B.W.

what is full form of DAC14th October 2006 at 10:22 #43039yellaiahGuest
Hi peter ,
If u want to measure frequency,measure it before the site ON-AIR(when OMU disable),
once site is On-Air , DAC value changes due to some BSS parameters.
