Frequency band 733-758 MHz will be used by different unspecified applications in Land Mobile Service. Average density of basestations in frequency band 703-733 MHz (Rx)/758-788 MHz (Tx) in 100 km zone from border is less than 1 station per 100 km 2 except in Narva (59N23; 28E10), Kohtla (59N22; 27E20) and Tartu (58N23; 26E43) area with 10 km radius, where basestation density may be 10 stations per 100 km 2 . The average effective antenna height above ground level is 40 m, maximum effective antenna height is 70 m. Transmitters are using antennas in three 120º sectors with maximum e.i.r.p value of 58 dBm and the down tilt of antenna is 3 degrees. Yours sincerely, Priit Soom Deputy Dir e ctor General
