As technology evolves, it provides the construction industry with additional tools to make processes more efficient and effective. Undoubtedly, companies of every size have benefitted from the myriad uses of WiFi (wireless fidelity), and now there is a new generation of wireless technology to consider: LiFi.

LiFi (light fidelity) is a wireless technology that transmits information by using light — as opposed to radio frequencies used for WiFi and cellular. Many corporations are supporting the rise of LiFi, seeing it as the next option for 5G core integration.

Radio frequency communication relies on antennas, radio circuits, and receivers. In contrast, LiFi functions with simpler, direct modulation processes — much like the infrared communication used for remote control devices.

A high-speed, mobile, and bidirectional communication technology, LiFi uses multiple light bulbs to form a wireless network. When an LED light bulb receives an electrical current, streams of light are produced from the bulb. The bulbs are like semiconductors, so the light they emit can change at high speeds. This means the LiFi can send signals by modulating the light at various intensities. The signals are received by detectors that can interpret the intensity as information. Since the human eye cannot detect this intensity modulation, the data communication is seamless. Thus, wherever there is LiFi-enabled light, LiFi users can be connected, and data can be transmitted.
