Led light bulbs in the house to get in the future the same processing power at their disposal such as smartphones have now. That claims to be professor Harald Haas, who researches lifi, a internet connection that works via light pulses.
Leds will be according to Haas in the future the same development undergone as mobile phones, which evolved from devices to make calls to devices with much more functionalities. That says, the in Great Britain active German professor Haas in an interview with IEEE. What features leds would get, in addition to that of the receiver and the transmitter of internet signals, mentions the professor. Previously experimented under more Philips all in one system for positioning in stores on the basis of led lamps.
Haas researches lifi, a technology for short-distance internet signals to pass by means of light pulses on high frequencies. With existing red, green and blue leds took his team speeds of 100Mbit/s, but by means of custom leds and systems should lifi able to signals with 15Gbit/s to transfer in the future. An advantage over wifi would be lower latency, while a disadvantage is that two points must be able to ‘see’: the signal can not pass through walls.
The research of lifi been running for years. The opportunity seems to present that the telecomautoriteit ITU lifi will record it as a 5g standard. The current expectation is that 5g will consist of a mix of technologies on a network can collaborate; lifi can provide internet connections over short distances.
