The millimeter-wave band, especially the unlicensed spectrum at the 60 GHz carrier frequency, is at the spectral frontier of high-bandwidth commercial wireless communication systems. Compared with microwave band communication, spectrum at 60 GHz is plentiful (frequencies of 57-64 GHz are available in North America and Korea, 59-66 GHz in Europe and Japan , ), but attenuation is more severe (20 dB larger free space path loss due to the order of magnitude increase in carrier frequency, 5-30 dB/km due to atmospheric conditions , and higher loss in common building materials ). These characteristics make 60 GHz communication most suitable for close-range applications of gigabit wireless data transfer.
