SkyBridge

Proposed Use 13.75–14.5 GHz SkyBridge uplink

SkyBridge LLC filed in 1997 with the FCC to provide fixed-satellite service operations from a network of 80 non-GSO satellites, operating 4 satellites per plane in 20 planes, inclined 53 deg. The satellites would be in circular orbits at an altitude of 1469.3 km. The FCC granted launch and operation authority to SkyBridge in 2005 (DA 05-2037), but SkyBridge was never launched.

In 2014, a company registered/operating under the names L5 and WorldVu, based in the Channel Islands, acquired SkyBridge's Ku-band spectrum rights at the ITU. According to a May 30, 2014, Space News article, WorldVu would consist of 360 small satellites operating at between 800 and 950 km altitude at an inclination of 88.2 deg (near polar orbit). Space News quotes the filing as indicating the satellite system would come into use in 2019 or 2020.

WorldVu is now known as OneWeb.

Proposed Air-Ground Broadband for Passengers Aboard Aircraft

Proposed Use 14–14.5 GHz

The FCC has proposed the establishment of a new air-ground mobile broadband service in the 14.0-14.5 GHz band. The current primary allocation is to the Fixed Satellite Service. The FCC proposes to achieve compatibility through “spatial diversity” rules, which would limit the directions in which antennas can point. Since the 14.0-14.5 GHz band is used for sending transmissions from the Earth towards satellites orbiting over the equator, U.S. earth stations all point south, more or less. Antennas in the proposed system would point north (in the case of ground stations) or downwards (in the case of the antennas on the aircraft), which should reduce their interference with satellite users.

The following information is edited from the FCC's Notice of Proposed Rulemaking,FCC 13-66:

We propose to establish a new, terrestrial-based air-ground mobile broadband service with aircraft in the 14.0-14.5 GHz band. The service would provide multi-gigabit broadband connectivity to aircraft flying within the contiguous United States. The service is intended for the business and personal use of passengers aboard aircraft, and will have no role in aeronautical operations or as a safety of life and property service.

The 14.0-14.5 GHz band is allocated on a primary basis to the FSS as an uplink (Earth-to-space) band for geostationary orbit (GSO) FSS operations. The air-ground mobile broadband service would operate on a secondary basis to GSO satellite systems and future non-geostationary orbit (NGSO) satellite systems, and on a co-secondary basis with the National Aeronautics and Space Administration (NASA) Tracking and Data Relay Satellite System (TDRSS) that operates under a Federal Fixed Service (FS) and Mobile Service (MS) allocation. In addition to coordinating with NASA TDRSS in the 14.0-14.2 GHz band, we propose that air-ground mobile broadband would also be required to coordinate with Radio Astronomy Service (RAS) users in the 14.47-14.5 GHz band, in accordance with the procedures set forth for other services in this band. To implement this service, we propose to amend Part 2 of the rules to add a secondary allocation in the non-Federal Aeronautical Mobile Service (AMS) for air-ground mobile broadband in the 14.0-14.5 GHz band.

We propose that under the rules we implement for the 14.0-14.5 GHz band to support the new allocation, we would require a licensee to use this spectrum for air-ground mobile broadband only. We also seek comment regarding the appropriate regulatory framework for the proposed provision of service. We seek comment on our proposal to classify the services as Commercial Mobile Radio Service (CMRS) given the proposed air-ground use of the spectrum. With respect to whether and how to apportion the spectrum, we seek comment on Qualcomm’s proposal to create two 250 megahertz licenses as well as on alternate approaches such as licensing the entire 500 megahertz of spectrum to a single licensee or dividing the spectrum into more than two blocks. Given the proposed air-ground use of the band, we propose to license the spectrum on a nationwide basis. We also seek comment on whether to adopt an open eligibility standard and whether to adopt any specific aggregation limits applicable to the initial licensing of the band.

To the extent that we adopt a geographic licensing scheme for the 14.0-14.5 GHz band, and permit the filing of mutually exclusive applications, we seek comment on a number of proposals relating to competitive bidding. We propose that the Commission conduct an auction in conformity with the general competitive bidding rules set forth in Part 1, Subpart Q, of the Commission’s rules, and seek comment regarding bidding credits for small businesses.
