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."

FCC gets five new applications for non-geostationary satellite constellations - SpaceNews.com March 2017
Boeing: “1,396 to 2,956 low-Earth orbit (LEO) satellites for providing connectivity”

SpaceX: VLEO, “V-band low-Earth orbit (LEO) constellation of 7,518 satellites to follow the operator’s initially proposed 4,425 satellites that would function in Ka- and Ku-band”

Telesat: “V-band LEO constellation as one that “will follow closely the design of the Ka-band LEO Constellation,” also using 117 satellites (not counting spares) as a second-generation overlay.”

Theia: “use V-band frequencies for gateways on the ground that would have originally only used Ka-band. The company wants to operate a constellation of satellites for both communications and remote sensing, and claims that because its spacecraft will have “regenerative” payloads, that “there is no specific relationship between V-band uplink frequency bands and downlink frequency bands.””

OneWeb: “operate a “sub-constellation” of 720 LEO V-band satellites at 1,200 kilometers, and another constellation in Medium Earth Orbit (MEO) of 1,280 satellites. Added together, that expands the OneWeb constellation by 2,000 satellites”

O3b: “up to 24 additional satellites that would operate in a circular equatorial orbit as a constellation called O3bN”
