UK broadband provider Virgin Media is trialing broadband speeds of up to 1.5 Gbps in London around Old Street, an area known as "Silicon Roundabout," including by members at TechHub, a community and workspace for technology entrepreneurs.The 1.5 Gbps download and 150 Mbps upload trial uses the same DOCSIS 3.0 infrastructure and technology as Virgin Media uses to provide residential customers with speeds of up to 100 Mbps, already being rolled out to more than half of all UK homes. The operator claims the 1.5 Gbps trial is the world's fastest cable connection and more than 240 times faster than the national average broadband.
