In June 2011, Comcast showed off a 1 Gigabits per second (Gbps) broadband connection. On Monday, Virgin Media, a UK-based cable company, said that it has started delivering a 1.5 Gbps broadband connection on a trial basis in a section of London known as Silicon Roundabout. The company describes it as the world’s fastest broadband connection:
The 1.5Gb download and 150Mb upload trial uses the same infrastructure and technology as Virgin Media uses to provide residential customers with speeds of up to 100Mb, already being rolled out to over half of all UK homes. Other businesses taking part in Virgin Media’s 1.5Gb trial include BespokeBanter.com, an online media outfit, and soproductions.tv, a video production company.
The DOCSIS2 technology used throughout Virgin Media’s network provides a future-proofed platform with theoretically near infinite capacity. Virgin Media is able to bond multiple downstream and upstream channels together to be used at the same time by a single subscriber to deliver faster speeds. DOCSIS 3.0, the current standard used throughout Virgin Media’s network, also incorporates support for Internet Protocol version 6 (IPv6). (Virgin Media press release)
