Phillips Says Light Bulbs Could Replace WiFi

Li-Fi is an idea that has been floating around for a few years but Phillips wants to make it a reality.

Phillips Li-Fi Technology is entering a real-world test in a Parisian architecture office, where LED light bulbs will replace their conventional Wi-Fi.

Yes, you read that right.

Li-fi wants to use visible and infrared light instead of radio signals in order to create a wireless internet network, which has a few big benefits. Unlike radio, light doesn’t penetrate walls or furniture, so it allows two computers to use the same bandwidth without interference. 

As we pointed out in an earlier report on Li-Fi technology, it could be 100 times faster than WiFi!

In order to create a Li-Fi network, you have to run internet cables and modems to all light fixtures that will participate in that network. The modem converts data packets and modulates LED lights in order to transmit signals, which are then captured by a USB dongle plugged into a laptop and converted back to data. When uploading, that USB dongle will send data up with infrared.

Of course, if some object gets in the way of the LED lights and dongles’ communication, your connection will be dropped. But still, let’s not throw shade its way, since it’s still in the early days and a few years away from mass adoption.

LiFi technology could find its way into a lot of open-space offices and environments which need to put a big emphasis on security. Because Li-Fi is based on light, not radio waves, it’s harder to intercept and it could ward off a lot of cybersecurity attacks currently threatening business operations.

“By plugging into a LiFi internet zone users can access and transfer data instantly by using a simple personal USB access key. The LiFi zone is completely secured within the pool of light created by the LED luminaire,” says Phillips.

For home use, we’d say that Li-Fi technology is still light-years away, though Phillips might have other plans!

It all depends on how the tests go so stay tuned, we’ll keep you updated.
