A SCOTS firm has continued its rise as a world tech leader in a demonstration of its LiFi technology connecting two off-the-shelf mobile phones.

Edinburgh-based pureLiFi has produced a video – shown at this year’s virtual Optical Fibre Conference (OFC) – showing the two devices, each with the company’s light antenna technology installed in consumer-style phone cases.

The cutting-edge demonstration showed how two LiFi enabled phones can connect to each other offering more reliable, faster, and more secure communications, which make it much more secure and easier to share data, collaborate and play games with friends using your mobile.

LiFi is a wireless technology that uses light rather than radio frequencies (RF) to transmit data.

By harnessing the light spectrum, it can unleash faster and more reliable wireless communications with unparalleled security, compared to conventional technologies, such as cellular, WiFi and Bluetooth. LiFi is a disruptive technology with almost limitless applications, and it has propelled the young Edinburgh company firmly into the spotlight in recent years.

Earlier this year, it scored a world first with a multi-million-pound deal to supply a futuristic communication system for the US Army in Europe.

Last year pureLiFi was crowned Scotland’s most innovative technology company after securing backing from a high-profile judging panel and readers of tech publication BusinessCloud.

The new video demonstrates how much LiFi technology has matured over the past few years, with pureLiFi now offering components ready for integration into everyday consumer electronics.

This latest demonstration is another milestone in realising pureLiFi’s vision to connect everything and everyone with LiFi.

Alistair Banham, the company CEO, previously described LiFi as a motorway compared to RF’s “country road”, with the light spectrum – 1000 times the bandwidth of RF – able to cope with significantly more data.

He debuted the video at this year’s OFC, saying: “With LiFi in a phone you can enable and enhance use cases like contactless payments and data sharing with military grade security.

“You can transfer 4K videos in just a few seconds or join in a multiplayer game with the same speed and reliability as your game console at home.

“With LiFi your phone can be more than just a slick bezel and a great camera.”
