60-GHz UWB System Performance Analysis for Gigabit M2M Communications

In this paper, the feasibility and performance of mm-wave 60 GHz ultra-wide band (UWB) systems for gigabit machine-to-machine (M2M) communications are analyzed. Specifically, based on specifications and experimental channel measurements and models for both LOS and NLOS scenarios, 60 GHz propagation mechanisms are summarized; 60 GHz UWB link budget and performance are analyzed. Tests were performed for determining ranges and antenna configurations. Results show that gigabit capacity can be achieved with omni-omni antenna configuration for LOS condition. When the LOS path is blocked by a moving person or radio wave propagation in NLOS situation, omni-directional antenna configuration is required for bigger range between machines in office rooms. Therefore, it is essential to keep a clear LOS path in M2M applications like gigabit data transfer in office rooms. The goal of this study is to provide useful information for design of 60 GHz UWB systems in gigabit M2M communications.
