Abstract: For purpose of promoting the coverage rate of Access Point (AP) in power distribution communication network, an AP planning model and the corresponding solving algorithm in the network composed of PON and wireless LTE private network are proposed. Firstly, the reliability of APs are analyzed according to their importance so that the covering mode can be determined. Secondly, considering the constraints of reliability and budget deployment cost, an AP planning problem model in PON-LTE mixed network is established with the aim of maximizing AP coverage rate. Then, the solution based on a hybrid of multiple intelligent optimization algorithms is proposed for this NP-hard problem. Finally, the proposed method is simulated to show the numerical network performance and the planning effect. The simulation results show that the proposed method owns better performance on coverage rate of AP in the LTE-PON mixed network than the strategies of separately deploying LTE or PON network.
