A study on a comprehensive protection ratio calculation applicable to initial planning for frequency coordination in the fixed wireless networks

This paper suggests an efficient and comprehensive algorithm of protection ratio derivation and illustrates some calculated results applicable to the initial planning for frequency coordination in the fixed wireless access networks. The net filter discrimination associated with Tx spectrum mask and overall Rx filter characteristic has been also examined to show the effect of the adjacent channel interference. The calculations for co-channel and adjacent channel protection ratios are performed for the current M/W frequency band of 6.7 GHz including Tx spectrum mask and Rx filter response. The proposed method gives some advantages of an easy and systematic extension for protection ratio calculation and is also capable of applying the same concept to frequency coordination of the fixed millimeter wave networks
