Low Cost 5G Wireless Backhaul Bridges Based on LED Technology

Posted May 14, 2018 by Prerit Tomar

Firefly LiFi - a manufacturer of Visible Light Communications (VLC) and Infrared Light Communications (ILC) LiFi products - is bringing affordable backhaul connectivity to 5G Smart City networks and the security camera market, using LED technology. Firefly LiFi demonstrated the fastest commercially available LiFi solution at the Global LiFi Congress in Paris, France, has been shipping indoor LiFi products, however, this new product addition is the company’s first solution designed for longer range indoor and outdoor point-to-point applications using advanced LED technology.

The solution is designed for building-to-building or lightpole-to-lightpole backhaul of WiFi, LiFi, 5G LTE, and IP security camera backhaul - using light spectrum to carry the data, rather than radio frequency (RF) technology. Firefly’s units are designed for ‘Wireless To The Home’ and Small Cells. Small Cells, which complement macro networks, are forecast to grow to US$2.2 billion in 2021 according to the Small Cell Forum and IHS Markit.

Its wireless bridge is ideal for both indoor communications and for license-free outdoor 5G backhaul and Small Cell applications - supporting ubiquitous coverage in carrier environments without the need for RF spectrum licensing, or complicated millimeter wave planning. This makes for robust load-bearing capacity, fast rollouts, and unsurpassed scalability. And it provides telecoms, businesses, schools, entertainment venues, and security integrators the ability to deploy wireless backhaul affordably, and without the congestion, capacity, and cyber security issues associated with RF solutions. And the system can be integrated with light fixtures - both conventional lighting and LiFi-enabled - and security camera systems.

Firefly LiFi’s wireless bridge is license free, immune to RF interference, avoids RF congestion in Metropolitan Area Networks, and is more secure than RF/WiFi backhaul solutions. It can be deployed on campuses - connecting school buildings - and be used in large facilities such as stadiums, warehouses, factories, airport terminals, and other venues.
