What is Li-Fi ?
LiFi( light fidelity) is a wireless technology which carry the key to solving challenges faced by 5G. LiFi can transmit at multiple gigabits, it is more reliable, virtually interference free and uniquely more secure compared to radio technology like Wi-Fi or cellular.
LiFi is a mobile
wireless technology that makes use of light rather than radio frequencies to
transmit data. The technology is upheld by a global ecosystem of companies
driving the adoption of LiFi, the next generation of wireless that is ready for
seamless integration into the 5G core.
How is works ?
Radio frequency communication requires radio circuits, antennas and complex receivers, whereas LiFi is much easier and uses direct modulation systems similar to those used in low-cost infrared communications devices such as remote control units. LED light bulbs have high intensities and therefore can achieve very wide ranging data rates.
- Speed and Bandwidth - The light spectrum is many
times wider than the radio spectrum, which increases the volume of data it
can carry and transmit it per second .
- Reliability - Lifi transmits its signal
without any interruptions, which make communication more stable than Wifi.
- Cheaper - It is upto 10 times cheaper
than wifi, is more sustainable, uses less energy.
- Wireless - It takes advantage of light
and dispenses with router, so it successfully works without the use of
cables.
