From Boeing to SpaceX: 11 companies looking to shake up the satellite space | FierceWireless
"Companies filed with the FCC last year to launch 8,731 non-geostationary orbit (NGSO) communications satellites, according to Parabolic Arc. Not all of them are proposing to connect the unconnected to the internet; some are geared toward IoT and others are looking at serving the space industry. Performance is expected to be far better than previous satellite generations, with fiberlike speeds and lower latency."

New Dual-band Ku/Ka Terminal Enables In-flight Network Switching Across Commercial Ku- and Ka-band Satellite Networks | ViaSat
"In-flight network switching between commercial Ku- and Ka-band satellites has been successfully demonstrated by ViaSat Inc. (NASDAQ: VSAT), using its innovative dual-band terminal and a new radome. The test flights, conducted in July and August on a commercial 757-200 aircraft, demonstrated the state of the art in broadband enroute communications with the aircraft transitioning among multiple satellite beams from six satellites and three Ku- and Ka-band networks."

"Over the past year, ViaSat Exede® in-flight internet has enabled broadband satcom communications on 200 commercial aircraft operating over the ViaSat high-capacity Ka-band satellite network in North America. "

Dish Network battles OneWeb and SpaceX for Ku-band spectrum rights - SpaceNews.com June 2016
FCC filing

"A coalition of 5G terrestrial mobile broadband companies led by Charlie Ergen’s Dish Network on June 8 asked U.S. regulators to strip future low-orbiting satellite Internet constellations of their priority access to 500 megahertz of Ku-band spectrum – spectrum coveted by prospective constellation operators including OneWeb LLC and SpaceX."

“There is simply no basis to jeopardize 5G [Multi-Channel Video Distribution and Data Service, or MVDDS] deployment to give additional spectrum to a speculative NGSO service that already has access to ample spectrum,” the MVDDA Coalition said in its FCC petition, referring specifically to OneWeb.

"The coalition said a recent study performed by Tom Peters, a former chief engineer at the FCC’s Wireless Telecommunications Bureau, found that new technology would permit 5G to coexist in this spectrum with current direct-broadcast television satellite signals. The coalition concedes that no such spectrum sharing is possible with low-orbiting satellite systems without “severe operational constraints on MVDDS, NGSO FSS [fixed satellite service] or both services.”"

"Hawthorne, California-based SpaceX, a growing provider of launch services, in January 2015 announced that it would build a satellite production facility in Seattle, Washington, for a constellation of 4,000 satellites, also using Ku-band for the links to end users."

Satellite industry opposes Qualcomm's proposed in-flight mobile broadband service — PolicyTracker: the spectrum management newsletter
"The US regulator is considering a Qualcomm request for a passenger in-flight mobile broadband service in the 14.0-14.5 GHz band. US satellite operators are opposed to the proposal, which could also have implications for European operators." "The new service would operate in the 14.0-14.5 GHz band on a secondary, non-interference basis for fixed satellite service (FSS) earth-to-space communications. The key to such sharing is spatial diversity, with FSS earth station antennas oriented to the south and above the horizon, air-ground mobile broadband base stations pointing to the north, and air-ground mobile broadband aircraft stations oriented below the horizon, the NPRM said. Air-ground mobile broadband services would have to protect primary FSS in the band from harmful interference, and also accommodate other federal and non-federal users."
