Supersonic DOCSIS: 15 Gigabit Cable 2020, 50-80 Gigabits 2030
Tom Cloonan of Arris is confident of remarkable speeds. (Video and transcript below). At CableLabs' 2015 summer event he predicted DOCSIS would reach 15 gig (shared) in a few years and 50-80 gig a decade later. 15 gigabits would require using 1.7 GHz and higher speeds would require going to 6GHz and more. Jeff Baumgartner at Multichannel calls this "supersonic DOCSIS."
"Sound crazy?" Cloonan asks. "Maybe, maybe not." Higher frequencies attenuate quickly in longer cables. If you run fiber to the edge of the drop cable, the loss is modest. At CableLabs, they demonstrated a 6 GHz signal over 50 meters of drop cable. 50 gigabits, here we come.
DSL has already done this, going from 1.5 megabit HDSL in 1995 to near gigabit G.fast over 106 GHz in 2015, Cloonan graciously acknowledges.
Compensation to be negotiated. SASAC, the State Holding Company, will have 50% - 1 share in the combined Nokia China and Alcatel Shanghai Bell. Yuan Xin will continue as chairman and party secretary. No word yet on whether Luis Martinez-Amago will continue as second in command. Nokia, the European survivor, will have 50% +1 but is unlikely ever to challenge Chinese control. Chinese sales are absolutely crucial to Alcatel and Nokia. They had no real negotiating room and had to take whatever the Chinese offered.
Jean-Paul Sartre died in 1980. There were fewer than a thousand cellphones in the world. The World Wide Web was a decade away. He's the most prominent existentialist philosopher. There's no obvious connection between his work and this analysis of the impact of Wi-Fi on telephone companies.
Realworld likely speeds of 50-150 megabits 90+% of the time. Two 20 MHz bands will deliver speeds like this. You rarely will need that kind of speed but higher capacity wireless means more bandwidth for all. The 2 gigabyte and 5 gigabyte caps need to disappear and they will where there's enough competition. 55% of Singapore is covered now and they'll be close to 100% next year.
