The Truelifi series includes communication lights and transceivers that can be adapted to existing household lighting systems. If the speed is not fast enough, two fixed points can be wirelessly connected, and the data rate can be superimposed to 250 Mbps.

Signify's original goal was to focus on professional markets such as long-term lighted office buildings and hospitals, rather than families, but the maturity of technology has made it possible to reach a wider audience.

Li-Fi technology has existed for many years - but so far it has not been widely adopted. Most devices connected to the Internet (such as laptops and intelligence)Mobile phone) An external adapter is needed to receive data through Li-Fi. Because of visible light communication, the signal will be blocked when the receiver is covered and blocked. Signify also said that its Truelifi product needed a USB interface to receive Li-Fi signals.

However, in appropriate cases, Li-Fi has the advantage of using light instead of radio signals to transmit data. For example, it can be used in areas where there may be a lot of radio frequency interference, or in hospitals where RF signals may interfere with sensitive machines. Although making shadows can easily block Li-Fi signals, this disadvantage in turn enables precise directional communication, because users can better control the location of network propagation by occluding visible light.
