Philips Hue announces lights that can transmit data at 250 Mbps


Signify, the company formerly known as Philips Lighting, which produces Hue brand intelligent lamps, has announced a new range of Li-Fi Internet transmission lights called Truelifi. They are capable of transmitting data to devices such as laptops at speeds of up to 150 Mbps using light waves instead of the radio signals used by 4G or Wi-Fi. The product range will consist of both new lights and transceivers that can be adapted to existing lighting. The technology can also be used to wirelessly connect two fixed points with speeds up to 250 Mbps.

Signify, a leading lighting provider, is initially targeting professional markets such as office buildings and hospitals instead of residences where it has the potential to reach a much wider audience.

Li-Fi technology has been around for years – we even tested a prototype of Oledcomm's work at CES 2018 – but so far it has not taken off. Most Internet-connected devices, such as laptops and smartphones, need an external adapter to receive data via Li-Fi, and even then, the signal may be blocked when the receiver is in the shade. Signify says you need to connect a USB access key to a laptop to receive a Li-Fi signal from your Truelifi products.

In the right circumstances, however, the use of Li-Fi light instead of radio signals to transmit data has its advantages. For example, it can be used in areas where there may be too much radio frequency interference or in places such as hospitals where RF could interfere with sensitive machines. Although Li-Fi signals can be easily blocked, this disadvantage can be a benefit to security applications, since you have much more control over where the network spreads.
