Fastest-ever internet speed recorded in London

Even as internet users demand for higher bandwidth, the two communication groups Alcatel-Lucent and BT, achieved internet speeds of 1.4 tera bits per second creating world record with spectral efficiency of 5.7 bits per second Hz over core network during joint testing in London.

One byte is equivalent to eight bits, and is enough, BT said, to send 44 uncompressed HD movies each second. Remarkably, though, such high speeds were achieved using existing fibre cable technology. Essentially, an existing 410 km fibre link between the BT Tower in London and BT’s Adastral Park research campus in Suffolk.

“A a new ‘flexible grid’ infrastructure (Flexgrid) was also used to vary the gaps between transmission channels, usually set at 50 gigahertz. By increasing the density of channels on the fiber, this approach achieved up to 42.5% greater data transmission efficiency compared to today’s standard networks,” the Alcatel-Lucent website informs.

So considering the technology can function on existing infrastructure the success of this test promises of path breaking real world applications. However, it is speculated that consumer implementations may take a few years.

Currently, Asian countries have dominated World’s national average internet speed with South Korea holding the top most position at an average of 14 Mb per second. They are followed by Japan at an average of 11.6 Mbps, and Hong Kong at 9.3 Mb per second.
