Alcatel-Lucent and BT test transmission to 1.4 Tbps

Alcatel-Lucent and the British operator BT announced that they had reached in test performed in London, speeds of 1.4 Tbps in optical fiber transmission with spectral efficiency of 5.7 bits per second per Hertz. According to the companies, would be 'the fastest connection ever reached in commercial real hardware environment'. The speed would be equivalent to the transmission of 44 movies in high resolution in one second.

The field test was done in a link of 410 km between the BT Tower in the English capital and the company's research campus in Suffolk fiber. By expanding the density of channels, the experience would have enhanced the efficiency of transmission by 42.5% compared with existing networks.

According to a statement from Alcatel-Lucent, "the increase in capacity occurred with existing optical fiber, potentially reducing the cost of deploying more fiber with the increasing demand for bandwidth."

BT trials new network tech for ‘Internet of Things’

BT has begun trialling a new technology from tech company Neul on machine-to-machine (M2M) communications using ‘white space’ technology.

These tests involve sending traffic information to and from moving vehicles via gaps – or ‘white spaces’ – in the frequencies bands used for digital TV broadcasting.

White space networking could enable up to 50 billion devices to be connected wirelessly to the internet by 2020, say BT.

“The internet of things market has huge potential, but existing short-range and cellular networking technologies are unable to meet the requirements of many applications we see,” Mark Harrop, director of mobile strategy at BT, said. “A networking technology that can provide deep indoor coverage, last for many years from a single battery, is simple to use, and comes at the right price point is essential for realizing the true potential of the internet of things.”

Bins that ask to be emptied

BT has been conducting these trials since late last year, but now they are using the new NeulNET system. The NeulNET system provides two-way, wide area M2M networking that Neul claims “far outreaches today’s GPRS, 3G, CDMA and LTE WAN solutions”.

The NeulNET system uses an antenna-equipped base station that can provide wireless coverage in a radius of up to five kilometers, along with terminal modules that can run for up to 15 years on two AA batteries and can communicate from deep within buildings or underground.

The system, delivered by Neul as a cloud-based managed communication service, can operate in either licensed or unlicensed spectrum, and across a wide range of frequency bands.

Neul adds that it expects to announce further deployments of its NeulNET technology throughout 2014. It says the system could enable smart-city applications ranging from waste-disposal bins that “ask to be emptied” to green-belt areas and farms that are monitored and watered efficiently.
