Millimeter Wave board

Millimeter wave is an electromagnetic spectrum band that can be used in a variety of products and services, including high-speed, point-to-point wireless local area networks (WLANs) and internet access. Millimeter wave is utilized in telecommunications for a range of services on mobile and wireless networks because it allows for larger data rates than lower frequencies, such as those used for Wi-Fi and existing cellular networks.

Because of shorter wavelengths on millimeter wave, the 71- 76 GHz, 81- 86 GHz, and 92- 95 GHz( 70/ 80/ 90 GHz) bands permit the use of smaller antennas, than would be required for similar circumstances in the lower bands, to achieve the same high directivity and high gain. The immediate consequence of this high directivity, coupled with the high free space loss at these frequencies, is the possibility of a more efficient use of the spectrum for point- to- multipoint applications. Since a greater number of high directive antennas can be placed than less directive antennas in a given area, the net result is higher reuse of the spectrum, and higher density of users, as compared to lower frequencies. Furthermore, due to the fact that one can place more voice channels or broadband information using a Millimeter Wave board to transmit the information, this spectrum could potentially be used as a replacement for or supplement to fiber optics.
