Exposure Minimization in Indoor Wireless Networks

This letter presents the impact of indoor wireless network planning on human exposure to radiowaves and suggests network configurations that targets exposure minimization. The aim is to deploy an indoor wireless network with the minimum radiation impact on humans. The indoor environment is modeled in a vector format, and a deterministic ray tracing algorithm is used for field predictions. For the purpose of the investigation, a genetic algorithm (GA) optimization technique is developed. It is shown that exposure due to the transmitting stations and the terminal devices can be minimized when the network is deployed in an optimum way. A robust and effective planning tool is suggested.
