Footnotes

5.547 The bands 31.8-33.4 GHz, 37-40 GHz, 40.5-43.5 GHz, 51.4-52.6 GHz, 55.78-59 GHz and 64-66 GHz are available for high-density applications in the fixed service (see Resolution 75 (WRC-2000)*). Administrations should take this into account when considering regulatory provisions in relation to these bands. Because of the potential deployment of high-density applications in the fixed-satellite service in the bands 39.5-40 GHz and 40.5-42 GHz (see No. 5.516B), administrations should further take into account potential constraints to high-density applications in the fixed service, as appropriate. *This resolution was revised by WRC-12. (WRC 07)

Band Uses (65 - 66 GHz)

802.11/WLAN/Wi-Fi/WiGig

Wireless LANS utilize various channels in the 2.4, 5, and 6 GHz bands (multiple countries), and (in theory) the 3.6 GHz band (U.S. only). For a list of which channels are available in which regions, refer to the Wikipedia article.

Wi-Fi is a trademark permitted for devices that are based upon a published standard of the IEEE 802.11 committee and that have been certified by the Wi-Fi Alliance. Wi-Fi is presently incorporated in about three billion devices. Wireless cash registers were one of the earliest applications of what is now Wi-Fi.

Wi-Fi devices operate on an unlicensed basis, generally meaning they cannot cause interference to licensed services, and must accept any interference caused to them. Wi-Fi shares bands with other unlicensed or ISM devices, such as cordless phones at 2.4 and 5.8 GHz and microwave ovens at 2.4 GHz.

Some of the key patents related to Wi-Fi are credited (in the courts at least) to the Commonwealth Scientific and Industrial Research Organisation (CSIRO) in Australia, which has collected over $400 million in royalties and legal settlements over patent rights.

V-band

The range 57-66 GHz is considered the V-band. According to ETSI:

"V-Band is characterized by a continuous block of 9 GHz of spectrum between 57 and 66 GHz, oxygen absorption that implies immunity to interference and enhanced frequency re-use, a favourable licence regime, mostly unlicensed or light licensed (country dependent)."

Please see the document section for a link to an ETSI report on worldwide regulation of V-band and E-band.

FCC Proceeding (3)

FCC Above 24 GHz Mobile Radio Services Notice of Inquiry

In this Notice of Inquiry, we begin a proceeding to examine the potential for the provision of mobile radio services in bands above 24 GHz. As technologies continue to evolve, innovators are working to tap into the potential of using high-band spectrum for mobile services. In particular, industry and technical groups are beginning to examine the use of higher frequencies sometimes known as millimeter wave (mmW) bands for mobile use. This examination of the possible uses of the mmW bands for mobile use takes place within the context of broader efforts to develop technical standards for so-called Fifth Generation (5G) mobile services. In view of the technological and marketplace developments outlined in this item, we seek to discern what frequency bands above 24 GHz would be most suitable for mobile services, and to begin developing a record on mobile service rules and a licensing framework for mobile services in those bands.

Above 24 GHz Mobile Broadband Notice of Proposed Rulemaking

Today we take further steps to promote a flexible regulatory environment for the next generation of wireless services. In this Notice of Proposed Rulemaking, we continue our examination of higher frequency bands for mobile and other uses. In that regard, we identify specific spectrum bands above 24 GHz that appear to be suitable for mobile service, and we seek comment on proposed service rules that would authorize mobile and other operations in those bands. This development of service rules for mobile use of the millimeter wave (mmW) bands occurs in the context of our efforts to develop a regulatory framework that will help facilitate so-called Fifth Generation (5G) mobile services.

FCC Above 24 GHz Report and Order and Further Notice of Proposed Rulemaking

According to the FCC:

Today, we take a significant step towards securing the Nation’s future in the next generational evolution of wireless technology to so-called 5G. We build upon years of successful spectrum policy – including flexible use, unlicensed, and sharing policies – to create service rules for using four spectrum bands above 24 GHz. These high frequencies previously have been best suited for satellite or fixed microwave applications; however, recent technological breakthroughs have newly enabled advanced mobile services in these bands, notably including very high speed and low latency services. To promote the deployment of these highly beneficial technologies, we are acting quickly –- more quickly than most of our counterparts around the world – to establish a coherent framework built on a robust public record. In addition to this significant step forward, we will also continue to explore new opportunities to make additional bands available and to explore other issues, including robust Federal sharing, raised in the accompanying Further Notice of Proposed Rulemaking.
