I first wrote about Li-Fi, a new delivery method that uses light bulbs instead of radio waves to transmit wireless signals, back on Halloween 2013 but it’s worth re-visiting as it is now being tested in a real workplace for the first time. According to published reports the trial run, which was conducted in Estonia at a tech startup called Velmini, netted speeds of 1 gigabit per second.
Why is this significant? As Quartz puts it: “Light-speed internet may be upon us. A technology called ‘Li-Fi’ uses light waves from ordinary LED light bulbs to deliver internet connectivity that is cheaper, more secure and 100 times faster that broadband internet.”
One hundred times faster than traditional Wi-Fi?!! Now that’s what I’m talking about!
There are some drawbacks, however, such as the fact that it doesn’t work through walls or outside where sunlight interferes with the signal. But that’s okay. Rather than replacing traditional Wi-Fi it can supplement it. Working in places where traditional Wi-Fi is not allowed such as on planes or in hospitals.
As of now we’re still about three years away from this technology becoming commercially viable but it may be worth the wait if lab test results are to be believed. That’s because lab simulations have shown that this technology could be used to generate data transmittal speeds of up to 224 gigabits per second. By comparison the record for traditional broadband speed is 10 Gbps.
Is Li-Fi the Greatest Idea Ever?
