Method and device for predicting interference of outdoor wireless network to indoor wireless network

Abstract

The invention provides a method and device for predicting the interference of an outdoor wireless network to an indoor wireless network. The method comprises the following steps of: acquiring an outdoor distance from an outdoor interference base station to a target building where a target terminal is located and an interference base station parameter; obtaining unit outdoor wall surface signal power according to the outdoor distance and the interference base station parameter; acquiring a signal penetration loss value of the target building to obtain unit indoor wall surface signal power; obtaining unit outdoor signal power at the target terminal; and carrying out wall surface integration of the target building on the unit outdoor signal power to obtain outdoor signal power at the target terminal. The propagation of an outdoor wireless network signal to the indoor is divided into an outdoor propagation part, a wall penetration part and an indoor propagation part, thus, the interference level at the target terminal can be rapidly and precisely obtained, filed simulated test carried out by technical personnel is avoided, and the indoor wireless network planning and designing efficiencies are increased.

Description

technical field [0001] The invention relates to communication technology, in particular to a method and device for predicting interference from an outdoor wireless network to an indoor wireless network. Background technique [0002] In the era of the third-generation mobile communication network, high-speed wireless networks have begun to enter the lives of thousands of households. Under the strong market demand, major operators have already started to carry out unified indoor and outdoor collaborative optimization for the unified planning of the whole network. Among them, indoor network planning is a part that needs to be considered. [0003] At present, during the planning and design of indoor wireless networks, the leakage of outdoor wireless network signals indoors must be resolved to prevent outdoor wireless signals from having a greater impact on indoor signals, resulting in enlarged switching areas and frequent switching. In the prior art, technicians usually conduc...
