5.458 In the band 6 425-7 075 MHz, passive microwave sensor measurements are carried out over the oceans. In the band 7 075-7 250 MHz, passive microwave sensor measurements are carried out. Administrations should bear in mind the needs of the Earth exploration-satellite (passive) and space research (passive) services in their future planning of the bands 6 425-7 075 MHz and 7 075-7 250 MHz.
5.459 Additional allocation: in the Russian Federation, the frequency bands 7 100-7 155 MHz and 7 190 7 235 MHz are also allocated to the space operation service (Earth-to-space) on a primary basis, subject to agreement obtained under No. 9.21. In the frequency band 7 190-7 235 MHz, with respect to the Earth exploration-satellite service (Earth-to-space), No. 9.21 does not apply. (WRC 15)
NG118 In the bands 2025-2110 MHz, 6875-7125 MHz, and 12.7-13.25 GHz, television translator relay stations may be authorized to use frequencies on a secondary basis to other stations in the Television Broadcast Auxiliary Service that are operating in accordance with the Table of Frequency Allocations.
NG171 In the band 6875-7125 MHz, the following two channels should be used for airborne TV pickup stations, wherever possible: 7075-7100 MHz and 7100-7125 MHz.

6 GHz Fixed Service Band

Current Use 5925–7125 MHz 6 GHz fixed service links

The 6 GHz fixed service bands are usually the first choice for long microwave links (tens of kilometers or more). The "Lower 6" band at 5925-6425 MHz is shared on a co-primary basis with the Fixed Satellite Service (uplinks), which hinders frequency coordination in some areas.

802.11/WLAN/Wi-Fi/WiGig

Current Use 5925–7125 MHz Wireless LANs (U-NII-5, U-NII-6, U-NII-7, U-NII-8)

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.

Unlicensed Level Probing Radars

Proposed Use 5925–7250 MHz

The FCC has released a Notice of Proposed Rule Making that would allow downward-pointing, unlicensed level probing radars, for use both in tanks and outdoors, at 5.925-7.250, 24.05-29, and 75-85 GHz.

Proposed EIRP boresight emissions limits are:

5.925-7.250 GHz: -33 dBm/MHz average and +7 dBm across 50 MHz.
24.05-29 GHz: -14 dBm/MHz average and +26 dBm across 50 MHz
75-85 GHz: -3 dBm/MHz average and +34 dBm across 50 MHz

Proposed average emissions limits to the sides and upward are:

5.925-7.250 GHz: -55 dBm/MHz
24.05-29 GHz: -41.3 dBm/MHz
75-85 GHz: -41.3 dBm/MHz

Wideband Systems under 15.250

Current Use 5925–7250 MHz Wideband systems (FCC part 15.250)

Part 15 of the FCC's rules accommodates operation of wideband systems in this band. The -10 dB bandwidth of the systems must be at least 50 MHz, but must be fully contained within 5925-7250 MHz. Average power of the devices is limited to -41.3 dBm. Peak power can be as high as 0 dBm across 50 MHz, which makes the band suitable for devices that generate a wideband signal by emitting a train of short pulses. Devices under this rule section may not be operated aboard aircraft or satellites.

Historical Use 7000–8000 MHz Possible new primary EESS allocation (WRC-15 agenda item 1.11)

ITU World Radiocommunication Conference 2015 Agenda Item 1.11:

"To consider a primary allocation for the Earth exploration-satellite service (Earth-to-space) in the 7-8 GHz range, in accordance with Resolution 650 (WRC-12)"

WRC 23 Agenda Item 1.2 IMT identification

Proposed Use 7025–7125 MHz Possible IMT identification

"to consider identification of the frequency bands 3 300-3 400 MHz, 3 600-3 800 MHz, 6 425-7 025 MHz, 7 025-7 125 MHz and 10.0-10.5 GHz for International Mobile Telecommunications (IMT), including possible additional allocations to the mobile service on a primary basis, in accordance with Resolution 245 (WRC-19);"
