pureLiFi, the home of LiFi, is recognised as the leader in the field – the use of the visible light spectrum instead of radio frequencies to enable wireless data communication. pureLiFi provides ubiquitous high-speed wireless access that offers substantially greater security, safety and data densities than Wi-Fi along with inherent properties that eliminate unwanted external network intrusion. In addition, the integration of illumination and data services generates a measurable reduction in both infrastructure complexity and energy consumption.
Li-Fi is a bidirectional, high speed and fully networked wireless communication technology similar to Wi-Fi. Coined by Prof. Harald Haas, Li-Fi is a subset ofoptical wireless communications (OWC) and can be a complement to RF communication (Wi-Fi or Cellular network), or a replacement in contexts of data broadcasting.
It is wireless and uses visible light communication or infra-red and near ultraviolet (instead of radio frequency waves) spectrum, part of Optical wireless communications technology, which carries much more information, and has been proposed as a solution to the RF-bandwidth limitations. A complete solution includes an industry led standardization process.
What is “LiFi”?
Prof. Harald Haas coined the term “LiFi” at his TED Global talk to describe the high speed, bidirectional, networked and mobile wireless communication of data using light.

JIm, W6LG shows how he recently used 2 off the shelf coax switches to connect 2 antennas to his transceiver at the same time. This simple solution replaced a box with vacuum relays, a control box and control cable. Read more
