LiFi Explained The Wireless Laser Tech That Could Leave 5G In The Dust

LiFi might not only give 5G a data speed run for its money, but could actually be the answer to many of the questions posed at the fifth-generation wireless technology. While 5G is now available in some locations, the market remains some distance away from what consumers have come to expect from the promise of 5G.

In a world where everything is connected, 5G is supposed to act as the data hub supplying everything from smartphones to smart cars with the data they need. One of the problems with 5G is that it relies on radio frequencies and they have limitations. Although light also has some of the same limitations, it is not quite as limiting as radio.

Put simply, the idea behind LiFi is that light bulbs can provide data to devices. Just like radio frequencies, light has a spectrum and utilizing that spectrum to deliver data means LiFi works regardless of whether the light is switched on or visible. This is not just a pipe dream either. As IEEE Spectrum points out, tech companies including pureLiFi and SLD Laser are already working on making LiFi a consumer reality. SLD Laser recently exhibited its LiFi-based solution during CES 2020, promising data speeds multiple times faster than what 5G offers. SLD Laser’s products potentially offer even greater performance than other competing LiFi products due to them utilizing lasers instead of LED lights.

Will LiFi Replace 5G

While many view solutions like 5G, Wi-Fi and LiFi as competing technologies, in the real world they are all part of a much wider and integrated solution. Like 5G and Wi-Fi, LiFi also has its own limitations. For example, most LiFi solutions are expected to use some form of visible light, which cannot pass through walls. With LiFi only providing data within the light source’s reach, the data it provides will also not be able to pass through walls. In theory, there would need to be a light source (bulb) covering everywhere a person, business or city wants data to be delivered, and that sort of deployment takes time. Likewise, it could be possible other light sources might interfere with data signals delivered by LiFi.

Due to LiFi and 5G having their own limitations, LiFi is probably best viewed as a likely counterpart to 5G. They are not competing for your data allowance, but instead could be used together to form a richer data delivery system overall. Where 5G is limited, LiFi could step in and vice versa. However, it may be some time before consumers actually start to see any LiFi products delivering data to their personal devices. Due to the benefits of greater amounts of data delivered faster and further, it is likely LiFi will first start to be tested and used commercially within some of the extremely data-heavy industries, such as autonomous vehicles.
