New Specification Could Speed Upload Times

Most Internet users make due with broadband upload speeds that are about ten times slower than their download speeds. But a new broadband specification could change that.

CableLabs has announced that it has completed work on an upgrade the DOCSIS 3.1 specification called Full Duplex DOCSIS 3.1. Within two years, the specification would allow cable Internet users to get 10 Gbps speeds for both uploads and downloads. And importantly, it would not require the installation of new fiber.

“In the United States, more than 90 percent of households are connected to an HFC (hybrid fiber-coaxial) network, and consumers typically have higher download speeds than upload speeds,” said CableLabs CEO Phil McKinney. “By enabling Full Duplex DOCSIS, the upstream and downstream traffic can flow at up to 10 Gigabits concurrently, doubling the efficiency of spectrum use.”
