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.
5.460A The use of the frequency band 7 190-7 250 MHz (Earth-to-space) by the Earth exploration-satellite service shall be limited to tracking, telemetry and command for the operation of spacecraft. Space stations operating in the Earth exploration-satellite service (Earth-to-space) in the frequency band 7 190-7 250 MHz shall not claim protection from existing and future stations in the fixed and mobile services, and No. 5.43A does not apply. No. 9.17 applies. Additionally, to ensure protection of the existing and future deployment of fixed and mobile services, the location of earth stations supporting spacecraft in the Earth exploration-satellite service in non-geostationary orbits or geostationary orbit shall maintain a separation distance of at least 10 km and 50 km, respectively, from the respective border(s) of neighbouring countries, unless a shorter distance is otherwise agreed between the corresponding administrations.

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.
