Signify also makes a faster version that offers up and download speeds of up to 250 Mbit / s. That Trulifi 6013 system, however, uses visible light beams of blue, red or green light and is a fixed point-to-point connection, whereby the sender and receiver must always be in the same place. With this variant, the company is mainly aiming at industrial environments, which is understandable because of the limitations and the colored, visible light beams. The French Oledcomm is also launching lifi products on the market . The company will be selling its LiFiMAX system from September. This consists of an access point with the appearance of a fire detector, with which up to sixteen users can simultaneously connect via a USB dongle. The Oledcomm system works outside the visible spectrum and offers download and upload speeds of up to 100 and 40 Mbit / s. According to the company, one access point can provide a space of 28 square meters with signal, but the signal strength decreases as the distance increases. The specified range applies at a minimum speed of 5 Mbit / s. A combination of an access point and one dongle will cost around eight hundred euros.
