Wi-Fi is the Internet standard that we’ve all come to depend on. It’s hard to imagine the modern workplace or home without it. But is the end of the Wi-Fi era already approaching? A new technology called LiFi (or Li-Fi) is being developed that could radically alter the way our devices connect to the Internet.
LiFi is short for Light Fidelity. It’s a wireless Internet standard that uses light to transmit information. It promises 1Gbps speeds, which is much faster than the current capabilities of Wi-Fi technology. Downloading massive files would only take a fraction of the time with this method. It’s a two-way communication technology that uses blinking LED lights to transmit data. The blinking happens so fast it’s imperceptible to the human eye. The tech dates back to 2011 and the inventor, Harald Haas, has claimed the tech has clocked a staggering 224Gbps in a closed lab environment.
This all sounds amazing! So what’s the catch? Currently, Wi-Fi signals can be transmitted through solid objects like walls and cubicles, but LiFi requires a direct line of sight and only works within a few meters of the transmitter. This severely hampers its ability to dethrone Wi-Fi as the de-facto standard. However, LiFI could still be the perfect solution for our increasingly smart homes. LiFi can be installed directly into the LED bulbs that are already lighting the home. This could provide lightning fast Internet for any nearby devices, as well as thermostats and other stationary home gadgets.
The capabilities and benefits of LiFi are still being discovered and tested, but it’s likely that LiFi will be infiltrating our lives and our homes in the not-so-distant future.
