The article illustrates the possibility of optimization of HFR network using Genetic Algorithm in order to determine positions of APs. Two new approaches are introduced to solve the global optimization problem the DIRECT and a hierarchic two step optimization combined with genetic algorithm. The methods are introduced and investigated for 1 2 3 and 6 AP cases. The influence of Genetic Algorithm parameters on the convergence has been tested and the optimal radio network is investigated. It has been shown that for finding proper placement the necessary number of APs can be reduced and therefore saving installation cost of WLAN or HFR. It has been shown that for finding proper placement the necessary number of RU can be reduced and therefore saving installation cost of HFR. The results clearly justify the advantage of the method we used but further investigations are necessary to combine and to model other wireless network elements like leaky cables fiber losses. Other promising direction is the extension of the optimization cost function with interference parameters of the wireless network part and with outer interference. 7. References Martin D.
