Moscow will test the technology for transmitting data using visible light


Moscow authorities in the spring of 2017 will begin testing the technology Li-Fi, which provides high-speed data transmission using visible light. After a year it can be implemented in the capital of MFC, schools and museums, said Deputy head of the Moscow Department of information technology Andrei Belozerov.

“While Li-Fi is more suitable for inner areas service centers, museums, schools. Solar street light, fog, or smog can create noise, though the manufacturers argue that the future of Li-Fi adapt and open spaces,” — said Belozerov.

The technology will be tested in the pavilion “Smart city” at ENEA. The official said, Li-Fi provides higher data transfer speed than Wi-Fi — 20-30 GB/s. In addition, the transmission of information via visible light better protected than electromagnetic radiation. Mass adoption may begin no earlier than 2018.

In the Department claim that Li-Fi should not cost more than existing solutions, which cost in 2016 175 million rubles: Moscow held a competition for the creation of a network of Wi-fi on the streets inside the Garden ring. It was won by OOO “Prestige-Internet” (included in JSC “ER-Telecom holding”). The operator must equip the 1.1 million access points and provide wireless network. To date, installed 300 access points.

Now the technology Li-Fi test Boeing and Lufthansa: aircraft light bulbs above the seats of passengers who can be a source of transmission, and it will not create interference to navigation equipment, said Belozerov.

President of Association of regional Telecom operators Yury Dombrovsky said that Li-Fi really higher speed than Wi-Fi, but this technology is experimental and expensive. The first time it can cost several times more expensive than the usual wireless network. For example, all capital equipment of the IFC may require hundreds of million dollars. The expert doubts that the technology will become wide-spread.

“Li-Fi need a special access point. Now the operators use these devices to transfer data between base stations. Street technology is dependent on weather conditions, indoor light does not pass through the wall,” said Dombrowski.

Free network of urban Wi-Fi is available in Moscow since 2012 in parks, pedestrian zones, as well as libraries, cultural centers and student hostels.In 2013, Wi-Fi launched in the capital’s subway. Now operates as one seamless area by public transport: metro, buses, trolley buses, trams and trains. If the passenger once connected to the network, after transfer to another mode of transport he will not have to log in to Wi-Fi.

Until the end of the year to a single network is planned to connect MCK and commuter trains. Wireless Internet is also available in 450 public transport stops, near metro stations, railway platforms and bus stations.
