At present, the wireless low frequency band 2.4GHz and 5.8GHz are allocated to the local wireless communication applications. They are widely used in 802.1bgn wireless WIFI, Bluetooth and microwave. The 60Ghz is a millimeter wave communication with 7 Gbps between devices with more wide wave spectrum range and information capacity. Since the 60Hz band has not been used in most applications, it can effectively avoid interference sources such as smart phone, routers, Bluetooth speakers or microwave ovens, etc.
