Research on frequency distribution and interference coordination method of power wireless private network based on service isolation

Allocating different frequency resources for different services is an important means to achieve end-to-end physical isolation of power wireless private network. However, the traditional frequency allocation method does not consider the characteristics of power services and isolation requirements. In this paper, a method of frequency allocation and interference coordination for wireless private network based on service isolation is proposed, the frequency allocation process for power service is designed, which can dynamically adjust the frequency subset according to the change of service demand of power service management area. On the basis of ensuring the service bearing isolation of different service areas, more flexible frequency allocation is realized, and the spectrum utilization efficiency is improved. In order to minimize the network interference, a cell interference coordination method for chain networking is proposed, which fully considers the service transmission characteristics and traffic distribution in different scenarios.
