PureLiFi, a developer of LiFi technology, has raised $18m in a series B funding round, which will enable the firm to provide components to mass-market mobile device and lighting manufacturers.
The funding round included Temasek, an investment company headquartered in Singapore, and the Scottish Investment Bank. The investment will allow the company to further develop Gigabit LiFi components and make them available in form factors ready for mobile device integration.
Light fidelity (Li-fi) is a mobile wireless technology that uses light rather than radio frequencies to transmit data. Li-fi comprises of multiple light bulbs that form a wireless network. When an electrical current is applied to a LED light bulb, a stream of photons is emitted from the bulb. LED bulbs are semiconductor devices, which means that the brightness of the light flowing through them can be changed at extremely high speeds. This permits the transmittance of signals through modulatiion of the light at different rates. The signal can then be received by a detector which interprets the changes in light intensity (the signal) as data.
PureLiFi announced its move from li-fi systems to components at Mobile World Congress in February where it demonstrated new Gigabit li-fi integrated into a laptop. Since this announcement, PureLiFi has been working with device manufacturers to integrate li-fi technology into commercial laptops, tablets and mobile devices.
Recently, PureLiFi announced its collaboration with Getac, a manufacturer of tablets and PC’s. The firm has also partnered with companies across several industries such as telecommunications company O2 Telefonica and lighting companies
