Everyone on the globe eventually might have to change its reliance on Wi-Fi to Li-Fi, a different technology that scientists claim can reach speeds of 1 Gbps in real-world use – that’s 100 times faster than your average Wi-Fi speeds.
At such speeds, a high-definition movie can be downloaded in only a few seconds.
A company called Velmenni informed the IB Times UK that it moved the Li-Fi technology out of the labs and into real-world industrial environments and offices in Estonia, where it was able to reach those speeds.
Li-Fi tranfsers data using LED lights, which flicker on and off within nanoseconds, undetectable by the human eye. Li-Fi was invented in 2011 in a lab, and has been able to achieve a mind-blowing speed of 224Gbps.
Dissimilar to Wi-Fi signals which can penetrate walls, Li-Fi uses light and cannot, therefore its range is theoretically more restricted. However, due to that limit, Li-Fi is also possibly more secure from external sniffing.
Li-Fi also opens more potential for smart home appliances. LED lightbulbs for the house could be used for two functions in the future – bringing light to a room and assisting in creating a network in the house for devices to communicate with each other.
Other than Velmenni, many other companies have already emerged to bring Li-FI to customers, such as pureLiFi and Oledcomm, the former established by Harald Haas, Li-Fi’s inventor himself.
Both companies provide kits to early adopters to install Li-Fi networks in the home and office, pureLiFi professes speeds of 10 Mbps with its present offering.
