FCC 14-154 4. 60 GHz Bands (57-64 GHz and 64-71 GHz) 70.
Bandwidth: 7 gigahertz and 7 gigahertz, respectively. 71.
Licensing Status:
There are no licensed operations in any of these bands. Unlicensed operation within the 57-64 GHz band is permitted under Part 15 of our rules.109
Non-Federal government operators of outdoor radio equipment in the 57-64 GHz band segment are not required to obtain individual licenses or seek coordination with NTIA if they limit average EIRP to 82 dBm minus 2 dB for every dB that their antenna gain is less than 51 dBi.110
Last year, the Commission expanded the use of Part 15 devices in the 57-64 GHz band in order to “help the Commission fulfill its objectives to bring broadband access to every American by providing additional competition in the broadband market, lowering costs for small business owners accessing broadband services, and supporting the deployment of 4th
generation (4G) and other wireless services in densely populated areas.”111
Specifically, the Commission allowed longer communication distances for outdoor point-to-point systems in the 57-64 GHz band by allowing higher powers, specified emission limits as an EIRP power level to provide uniformity and consistency in the rules, and eliminated the requirement for certain devices in the 57-64 GHz band to transmit identification information.112
Frequencies from 64-71 GHz are not among those listed in our rules as available for licenses issued in the terrestrial Fixed Service113
or for any satellite services except for inter-satellite service.114
Our rules list 65-71 GHz as available for Inter-Satellite (ISS) licenses,115
but there are no current ISS licenses.116 72.
Status of Mobile Allocation and Rights:
Each of the 60 GHz bands has co-primary mobile allocations.117
In the 64-66 GHz band, aeronautical mobile operation is prohibited.118
As noted above, the only operations in those bands are in the 57-64 GHz band pursuant to Part 15 of the rules. 73.
Other Authorized Services:
The 65-71 GHz band is authorized for ISS links.119
There are currently no active satellite licenses in that band. There is also a series of allocations for Federal and non-Federal Fixed, Radiolocation, Radionavigation-Satellite, Earth Exploration-Satellite, and ISS operations throughout these bands.120
International and domestic rules also indicate that any use of the 66-71 GHz band by the land mobile service is subject to not causing interference to, and accepting interference from, the space radiocommunication services in this band.121 74. We seek comment on the advisability of amending our rules to allow unlicensed Part 15 operations in the 64-71 GHz band segment. As an alternative, we seek comment on the possibility of authorizing licensed operations in that band. We request commenters to provide supporting information on existing or in development viable technology that would be envisioned for this band. We also seek comments on any interference that either licensed or unlicensed advanced mobile operations in the 65-71 GHz band segment Peter Ecclesine, Technology Analyst MS SJ-14-4 170 West Tasman Dr, San Jose, CA 95134-1706
