80% of American homes can receive a gigabit downstream from the cable company. Comcast announced they can reach 58 million locations with gigabit DOCSIS, almost their entire network. Charter, with almost as large a network, and #3, Cox, are also nearly all gigabit enabled. Customers are responding to the speed: in Q2, U.S. cable added about 585,000 subscribers while telcos lost about 130,000.
Similarly, Rogers in Canada offers a gigabit to all 4 million customers. They just reported their best quarter in years.
Cable wireless in the U.S. will be "humongous," a guy building the networks tells me. With fiber and power very close to most Americans, they will put small cells - 4G & 5G - almost everywhere. To match the Verizon & AT&T 5G nominal latency, DOCSIS latency needs to be < 10 ms. John Chapman at Cisco and Jennifer Andreoli-Fang at CableLabs have demonstrated a solution, DOCSIS pipelining. (Test pictured.)
Chapman tells me Full Duplex upstream is ready to come out of the labs. He expects wide deployments to begin in 2020. Speeds could reach a gigabit. Comcast and Charter are readying their networks.
