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 (4)

Further Notice of Proposed Rule Making on Regulations for Level Probing Radars

In this Further Notice of Proposed Rule Making (FNPRM), we are expanding the scope of
the above-referenced proceeding to propose a set of technical rules for the operation of unlicensed
level probing radars (LPR) in several frequency bands. LPR devices are low-power radars that
measure the level (relative height) of various substances in man-made or natural containments. In
open-air environments, LPR devices may be used to measure levels of materials such as coal piles or
water basin levels. An LPR device also may be installed inside an enclosure, e.g., a tank made of
materials such as steel or fiberglass and commonly referred to as a tank level probing radar (TLPR)
that could be filled with liquids or granulates. In the Notice of Proposed Rule Making and Order
(Notice and Order) in this proceeding, we proposed rules applicable only to TLPR devices for
operation in the 77-81 GHz band inside steel and concrete tanks, as that was the use requested by the
initial proponents. During the pendency of the rulemaking proceeding, but outside this proceeding, we received waiver requests and other inquiries regarding outdoor use on additional frequencies
under existing Part 15 rules for unlicensed devices.4 To address the apparent need for a
comprehensive and consistent approach to LPR devices, we are proposing in this FNPRM rules that
would apply to the operation of LPR devices installed in both open-air environments and inside
storage tanks in the following frequency bands: 5.925-7.250 GHz, 24.05-29.00 GHz, and 75-85 GHz.

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.

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.

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.
