Band Uses (92 - 94 GHz)

E-band

The range 71-76 and 81-86 GHz is considered the E-band. According to ETSI:

"E-Band: since 2000, regulators have made available high frequency bands at 71-76 GHz and 81-86 GHz. E-Band enables gigabit-per-second data rates given the huge amount of available spectrum (10 GHz) without any oxygen absorption, thus allowing longer distances compared to V-Band."

The E-band is frequently considered to also include the 92-95 GHz band.

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

70/80/90 GHz Bands

According to FCC document DA 16-974:

In 2003 the Commission adopted a Report and Order establishing service rules to promote non-Federal development and use of the “millimeter wave” spectrum in the 71-76 GHz, 81-86 GHz and 92-95 GHz bands on a shared basis with Federal Government operations. It modified those rules on reconsideration in 2005. The Commission adopted a flexible and innovative regulatory framework for the 70/80/90 GHz bands that allows for the issuance of an unlimited number of nonexclusive, nationwide licenses to non-Federal Government entities for a total of 12.9 gigahertz of spectrum allocated for commercial use. These licenses serve as a prerequisite for registering individual point-to-point links in a link registration system developed and managed by one or more third-party database managers. A licensee is not authorized to operate a link under its nationwide license until the link is both (1) coordinated with the National Telecommunications and Information Administration (NTIA) with respect to Federal Government operations and (2) registered as an approved link. The Report and Order noted that, in the past, the Commission had introduced market forces into the frequency coordination process wherever possible and appropriate because competition among coordinators promotes cost-based pricing and provides incentives for enhancing customer link management. Accordingly, the Commission directed the Bureau to select one or more database managers pursuant to its existing delegated authority and to consider the benefits of competition during the selection process. On that basis, the Commission determined that there was no reason to set limits on the fees charged by a
database manager.

In March 2004 the Bureau issued a public notice seeking proposals from parties interested in developing and managing the link registration system, and four parties initially submitted proposals. One party decided to remove its proposal from consideration, and the remaining three ultimately submitted an amended joint proposal on September 9, 2004 (Joint Proposal). Later in September 2004, the Bureau designated three companies to be Database Managers for the 70/80/90 GHz bands: Frequency Finder, Inc. (FFI), Micronet Communications, Inc. (Micronet), and Comsearch. In doing so, the Bureau rejected Comsearch’s original proposal to restrict frequency management in the 70/80/90 GHz bands to a single manager. The Bureau also reserved the discretion to designate additional managers or change the current designations at a later date if circumstances indicated that such action was warranted.

The Designation Order acknowledged that the Commission had envisioned a single, shared database if more than one database manager were selected, but the Bureau decided that it could accomplish the same purpose by accepting a joint proposal by the Database Managers to link their separate databases through coordinated communications to form a unified link registration system.

Accordingly, the Bureau required the Database Managers to build a cooperative environment to expedite link registrations through their combined efforts, sharing link information on a continuous basis to provide users, the public and the Commission with access to the most up to-date link information.

Database Managers register links and maintain a record of the requested and approved links for each licensee. In the event of an interference dispute, interference protection rights with regard to affected links are established based on the date and time of link registration, i.e., as between two or more links experiencing or causing interference, the link with the earliest registration date would acquire the right to protection from the later registered link or links, and so on in order of priority based upon the earliest date registered. The Designation Order noted that the Commission had expressly stated that Database Managers would not have authority to recommend specific frequencies to users, but would be responsible for keeping current link registration information to aid in resolution of interference disputes.

In 2005 the Commission revised its rules to (i) require licensees, for each link as part of the registration process, to submit a frequency interference analysis to a Database Manager, and (ii) direct the Database Managers to retain such analyses electronically for subsequent review by the public to aid in the resolution of any interference disputes that might subsequently arise. The Commission foresaw little likelihood that any such disputes would develop after operations commenced in the 70/80/90 GHz bands, but it provided an avenue for interference complaints to be submitted to, and resolved by, the Commission. The Reconsideration Order clarified that the Commission was neither requiring nor precluding Database Managers from providing additional services such as frequency coordination, link design or interference analyses.

FCC Proceeding (2)

FCC WRC-12 Notice of Proposed Rulemaking (FCC 15-50)

In the Notice of Proposed Rulemaking (WRC-12 Notice), we propose to amend Parts 2, 15, 80, 90, 97, and 101 of the Commission’s rules to implement allocation decisions from the WRC-12 Final Acts and make certain updates to our rules. Specifically, we propose to:

• Allocate the 8.3-11.3 kHz band to the meteorological aids service on a primary basis.

• Allocate the 472-479 kHz band (630 meter band) to the amateur service on a secondary basis.

• Amend the amateur service rules to provide for use of the 135.7-137.8 kHz (2200 meter) and 472-479 kHz (630 meter) bands. Amateur stations would share the band with power line carrier (PLC) systems operated by electric utilities. Amateur stations would be permitted to operate in these bands at fixed locations when separated from electric transmission lines by a specified distance.

• Amend Part 80 of the Commission’s rules to authorize radio buoy operations in the 1900-2000 kHz band under a ship station license.

• Limit the use of the 495-505 kHz band to the maritime mobile service.

• Allocate seven frequency bands (4.438-4.488 MHz, 5.25-5.275 MHz, 16.1-16.2 MHz, 24.45-24.65 MHz, 26.2-26.42 MHz, 41.015-41.665 MHz, and 43.35-44 MHz) to the radiolocation service (RLS) on a primary basis for Federal and non-Federal use, allocate the 13.45-13.55 MHz band to the RLS on a secondary basis for Federal and non-Federal use, limit the use of these RLS allocations to oceanographic radars, require that these radars not cause harmful interference to, or claim protection from, existing and future stations in the incumbent fixed and mobile services, and amend Part 90 of the Commission’s rules accordingly.

• Reallocate the 156.7625-156.7875 MHz (AIS 3) and 156.8125-156.8375 MHz (AIS 4) bands to the MSS (Earth-to-space) on a primary basis for Federal and non-Federal use to allow for greater probability of vessel tracking, with resulting benefits to maritime safety and security.

• Seek comment on the ability of Federal/non-Federal AMT stations to share spectrum with the incumbent services in the 4400-4940 MHz and 5925-6700 MHz bands.

• Extend the AM(R)S allocation from the 5091-5150 MHz band (adopted in the WRC-07 R&O) by also allocating the 5000-5091 MHz range to the AM(R)S on a primary basis for Federal and non-Federal use. AM(R)S use of the smaller 5000-5030 MHz range would extend the tuning range for AeroMACS, with the use of the 5010-5030 MHz band limited to those requirements that cannot be meet in the 5000-5010 MHz and 5091-5150 MHz bands. AM(R)S use of the 5030-5091 MHz band would support line-of-sight control links for unmanned aircraft.

• Allocate the 7850-7900 MHz band to the meteorological-satellite service (space-to-Earth) on a primary basis for Federal use.

• Allocate the 15.4-15.7 GHz band to the RLS on a primary basis for Federal use.

• Allocate the 22.55-23.15 GHz band to the space research service (SRS) (Earth-to-space) on a primary basis for Federal and non-Federal use and allocate the 25.5-27 GHz band to the SRS (space-to-Earth) on a primary basis for non-Federal use.

• Delete the aeronautical mobile service allocation from the 37-38 GHz band.

• Encourage operators of fixed stations operating in the 81-86 GHz and 92-94 GHz bands to take all reasonable steps to ensure that their unwanted emissions power in the 86-92 GHz band does not exceed the levels recommended by WRC-12.

FCC 70/80/90 GHz Report and Order and Further Notice of Proposed Rulemaking

Specifically, based on the record and following extensive consultation with federal stakeholders, in this Report and Order we authorize certain point-to-point links to endpoints in motion in the 71–76 GHz (the 70 GHz band) and 81–86 GHz (the 80 GHz band) bands under our part 101 rules to facilitate the use of these frequencies for access to broadband services on aircraft and ships. We also update our rules to permit the use of smaller and lower-cost antennas to facilitate the provision of backhaul service in the 70 GHz and 80 GHz bands and mandate a channelization plan in those bands. And we further adopt changes to the link registration process in the 70/80/90 GHz bands to require certification of construction of registered links, which will promote more efficient use of this spectrum and improve the accuracy of the link registration database. Finally, in the Further Notice, we seek comment on the potential inclusion of ship-to-aerostat transmissions as part of maritime operations otherwise authorized in this Report and Order and of Fixed Satellite Service (FSS) earth stations in our light-licensing regime for the 70 GHz and 80 GHz bands.
