In reality the signal correlations of the different receiving branches are not even close to the zero and the signal levels are not equal. The actual parameter ranges have to be taken into account when BTS sensitivity and diversity reception is determined. 3 Mobile station sensitivity Mobile station sensitivity covers the same parameters as the base station but diversity reception is not typically used at the mobile station receiving end. Mobile station suppliers have also improved sensitivity: the value of – 104 dBm, or better, has been frequently recorded.

3 reviews the conclusion that can be made: that traffic demand from the radio network and the average base station antenna height are the parameters that have to be optimised in order to maximise the overall radio quality called Quality of Service (the coverage, capacity, interference level and cost efficiency). Hence, an optimised radio network configuration can be provided by taking into account the characteristics of radio wave propagation in different environments. 08.

G. antenna gain, low noise amplifier (LNA), power amplifier (PA), diversity reception). The optimised base station configuration can finally be analysed by calculating the power budget for the BTS–MS connection for the uplink and downlink directions. The above mentioned capacity and coverage related equipment specifications can be taken into account in this power budget calculation and both coverage as well as capacity can be optimised. The above mentioned issues related to single band and multi band planning bring about new equipment (like multi band antennas, cables, LNAs, boosters and diplexers) and questions arising from their need at different base station sites.
