We all know that the NOKIA is a Finnish multinational company which only manufacture mobile phones, but, hold on, actually many of us are unaware of the true potential of the Finnish multinational company. NOKIA is a Finnish multinational communications and information technology company, founded in 1865.

After the sellout of its mobile phone business, the Finnish multinational company Nokia began to concentrate more broadly on its telecommunications infrastructure business, marked by the divestiture of its “Here Maps” division, its venture in virtual reality, and the acquisitions of French telecommunications company which is known as Alcatel-Lucent and digital health maker Withings in 2016.

However, the Nokia Bell Labs which became a subsidiary of Nokia Corporation after the takeover of Alcatel-Lucent. It was subsequently renamed Nokia Bell Labs. Nokia Bell Labs and the Technical University of Munich are responsible for a new technique for data transmission that can offer a terabit per second (Tbps) over fiber (could download the entire series of Game of Thrones in HD in one second).

But, for now, Google’s 1Gbps fiber network offers the best speeds to the home users. The new technique for data transmission is known as Probabilistic Constellation Shaping (PCS), competes directly with another advance technology in the world of optics presented by the researchers at University College London (UCL) earlier this year, ensuring speeds up to 1.25Tbps.

These Terabit networks could help to evolve into a more nimble Internet, as well as operators and companies that could improve the range and transmission capacity with the high-speed data networks.

The present system uses quadrature amplitude modulation (QAM) to achieve greater transmission capacity through a given channel, thus improving the spectral efficiency of optical communications, as indicated from Nokia.

The actual idea is to modify the probability with which the constellation points, the alphabet of the transmission, are used. Traditionally, all constellation points are used with equal frequency. PCS cleverly uses constellation points with a large amplitude less frequently than those with lower amplitude to transmit beacons that on average, are more repellent to noise and other deteriorations. This allows the transmission rate to be adapted ideally to the transmission channel.

However, the technology is yet to be released to the market, as there is still nothing confirm dates were announced for the implementation of this technology in real networks, but it seems to be the part of the revolution “5G” that we could actually expect to see on 2020.
