Internet Download Speed Hits 1,83,501Mbps in Test Scientists in the UK have achieved the "fastest ever" broadband speeds of 1.4 terabits per second . The joint test by British Telecom (BT) and French networking equipment company Alcatel-Lucent achieved the high speeds of 1.4 terabits per second, or 1,83,501Mbps, on the existing fibre network in London. The breakthrough is being seen as highly important for internet service providers (ISPs), as it means a greater amount of information can be sent through existing broadband infrastructure, reducing the need for costly upgrades. There are faster methods of transmitting data - such as the use of complex laser technology - but this is the first test to achieve such high speeds in "real world" conditions, outside testing labs, 'BBC News' reported. The test was conducted in October and Nove...
