Li fi technology

  1. 1. Lifi….the latest technology in wireless communication • LiFi is a new class of high intensity light source of solid state design bringing clean lighting solutions to general. • With energy efficiency, long useful lifetime, full spectrum and dimming , LiFi lighting applications work better compared to conventional approaches. • This technology gives the general construction of LiFi lighting systems and the basic technology building blocks behind their function.
  2. 2. Advantages • Using this innovative technology 10,000 to 20,000 bits per second of data can be transmitted simultaneously in parallel using a unique signal processing technology and special modulation • As communication technology is expanding at a rapid pace we are running out of radio frequency spectrum but this new visible light spectrum has 10,000 times more capacity than radio frequency. •
  3. 3. • Cellular masts or base stations worldwide uses a lot of energy particularly for cooling and it operates at only five percent efficiency whereas LiFi technology can transmit data through the 14 billion light bulbs already installed worldwide. So it is virtually free . • The whole process of transmitting data through light is more energy efficient than using radio frequency.
  4. 4. Applications • Can be used in the places where it is difficult to lay the optical fiber like hospitals. In operation theatre LiFi can be used for modern medical instruments. • In traffic signals LiFi can be used which will communicate with the LED lights of the cars and accident numbers can be decreased. • Thousand and millions of street lamps can be transferred to LiFi lamps to transfer data.
  5. 5. Conclusion • The design and construction of the LiFi light source enable efficiency, long stable life, full spectrum intensity that is digitally controlled and easy to use.
