Propagation and Interference Issues in a 60 GHz Mobile Network

Abstract

In the framework of the 4 th Generation Wireless (4GW) Infrastructure project, the study of new air interfaces is needed to provide a broadband wireless infrastructure to mobile users. The 60 GHz frequency band presents a very large bandwidth that has been allocated to mobile communication. In this paper, propagation and interference issues in different environments are presented and analyzed to identify the air interface limitations for the deployment of 60 GHz networks. Simulations using a ray-tracing tool show the dynamics of the interference in chosen situations. The very short time variation scales underline the need of ad-hoc solutions, directional antennas, fast and intelligent IP handovers, and efficient network design
