Luminescent paint makes LiFi networks more secure

“Smart paint” containing fluorescent and phosphorescent pigments could extend the possibilities of proposed LiFi networks, report a team led by K S Narayan at the Jawaharlal Nehru Centre for Advanced Scientific Research in Bengaluru, India. The researchers analysed the effect of nearby luminescent surfaces on the noise characteristics of visible light communication system (VLC) signals, and found that secondary emission could limit bandwidth locally by overwhelming receivers. The residual glow from phosphors could even be modulated to transmit a signal after the primary LED source has been turned off.

Visible improvement

LiFi uses visible and near-visible light to connect electronic devices in much the same way as now nearly ubiquitous WiFi. Like its more familiar counterpart, LiFi technology is expected to play a role in connecting devices within the incipient internet of things. Unlike microwaves, however, visible-light signals cannot pass through walls, meaning that LiFi networks are, in principle, less vulnerable to eavesdropping from outside.

Li-Fi Analysis on United States Market and Global Research in 2017

Li-Fi is the abbreviation of light fidelity and was expressed by Harald Hass who was a German physicist. In Li-Fi the information is transferred through light signals instead of radio waves and mostly Wi-Fi plays an efficient role for wireless information coverage within the buildings whereas by using Li-Fi we can provide the excel density data coverage in a particular area without any radio interference issue.

It furnishes well bandwidth, assurance than Wi-Fi and excels speed. In the coming generation, this technology will be used for transmitting data or information to smartphones, laptops etc. through the light in a room.Li-Fi or Light Fidelity refers to 5G Visible Light Communication systems using light-emitting diodes as a medium to high-speed communication in a similar manner as Wi-Fi.

Lucibel brings Li-Fi Internet connectivity to French hospital

Lighting systems manufacturer Lucibel announced that it has completed its first deployment of ‘LiFi by Lucibel’ in a hospital environment, installing the service in the cardiology department of the Stell clinic in the town of Rueil-Malmaison (Ile de France region). The company said that Li-Fi connectivity is particularly suited to areas within hospitals where the use of Wi-Fi is not recommended or forbidden, due to the risk of interference with medical equipment. The service also offers the additional benefit of providing hospital staff with a secure connection to access patient data.
