[Abstract] In this paper, the feasibility and performance of millimeter wave (mmWave) 60 GHz ultra?wide band (UWB) systems for gigabit machine?to?machine (M2M) communications are analyzed. Specifically, based on specifications, channel measurements and models for both line?of?sight (LOS) and non?LOS (NLOS) scenarios, 60 GHz propagation mechanisms are summarized, and 60 GHz UWB link budget and performance are analyzed. Tests are performed for determining ranges and antenna configurations. Results show that gigabit capacity can be achieved with omni?directional antennas configuration at the transceiver, especially in LOS conditions. When the LOS path is blocked by a moving person or by radiowave propagation in the NLOS situation, omni?directional and directional antennas configuration at the transceiver is required, especially for a larger range between machines in office rooms. Therefore, it is essential to keep a clear LOS path in M2M applications like gigabit data transfer. The goal of this work is to provide useful information for standardizations and design of 60 GHz UWB systems.
