The group, led by Intelsat, SES, Eutelsat and Telesat — four of the world’s largest satellite operators — agreed to offer up 200 megahertz of C-band spectrum for use in 5G mobile networks, up from the 100 megahertz first proposed in February by Intelsat, Intel and SES.
Intelsat and SES have said the loss of spectrum, especially 200 megahertz or more, would require new satellites to make up for lost capacity already in orbit. Under their plan, now embraced by Eutelsat and Telesat, cellular operators would be responsible for the cost of replacement infrastructure.
Looks like this move is solidifying, and may have interesting implications for the geostationary satellite production and launch markets.
