pureLiFi Announces The World First Large Scale Li Fi Deployment and Deal With The US ARMY Europe and Africa
pureLiFi and the US ARMY Europe and Africa
pureLiFi made the announcement of the world first large scale Li Fi deployment with the US ARMY Europe and Africa.
pureLiFi develops technology for communication networks that integrates data and lighting utility infrastructures. It offers Li-Fi enabled devices that convert the beam of lights into an electrical signal. The signal is then converted back into data. The company was founded in 2012 and is headquartered in Edinburgh.
This new deal aims to supply the pureLiFi kitefin system, a next-generation optical wireless communication system using LiFi for secure data transmission without radio frequencies. The deployment is composed of thousands of certified office and field-deployable LiFi units in real tactical and strategic environments. Kitefin™ is a newly developed system with unique features for defence use cases.

The use of Radio Frequencies (RF) in secure and Defense environments can bring many challenges; mainly, as RF is a technology that can be detected and targeted. pureLiFi stated on their website that the Kitefin Li Fi system eliminates this risk as it cannot be detected outside of its defined cone of coverage. The Kitefin™ system also allows for rapid setup and positive logistical impact saving time, money and lives on each deployment.
In 2019, a trialling of Li Fi technology with the US ARMY Europe and Africa took place. This helps to persuade key Army stakeholders in realising the great potential of Li Fi applications in the future of Defense communications.
CW5 Andrew Foreman, USAREUR-AF Chief Technology Officer said
” Including optical wireless in the commander’s toolbox is imperative to the survival of communications, command and control systems and, more importantly, Soldiers. Leadership within the Department of Defense are at a major transitional crossroads for communications and mission command systems and must make a critical decision.
Start deploying LiFi and FSO and explore other optical wireless communications technologies or continue to subject the warfighter to increased emission by continuing to field highly detectable RF systems to the tactical edge, thus putting Soldiers and systems in dire straits.”

Alistair Banham, CEO of pureLiFi, stated the following statement about the adoption of LiFi technology:
“This largest real-world deployment of LiFi with the US Army Europe and Africa is a testament to the benefits that LiFi can offer and the technology’s usability. If one of the most significant and advanced Defense organisations in the world can rely on LiFi for the most critical of communications, LiFi can offer unprecedented benefits to the consumer. LiFi, like so many technologies before it, is on a classic journey of adoption in Defense to wide-spread acceptance in the consumer market and eventually LiFi in everyone’s home
Since offering our gigabit components to the market we have developed some very innovative proof of concept integrations with some of the world’s largest consumer electronic and mobile phone brands. We are closer than ever to seeing consumers having LiFi in their homes and their pockets.
This first major deployment with the US ARMY Europe and Africa is just the beginning.”

What is Li-Fi?
Li-Fi, also known as "Light Fidelity" is a wireless optical networking technology, which uses light-emitting diodes (LEDs) to transmit data. In 2011, professor Harald Haas made a Li-Fi demonstration at the TED (Technology, Entertainment, Design) Global Talk on Visible Light Communication (VLC).

VLC uses light as a medium to deliver high-speed communication like Wi-Fi and complies with the IEEE standard IEEE 802.15.7. The IEEE 802.15.7 is a high-speed, bidirectional, and fully networked wireless communication technology-based standard similar to Wi-Fi's IEEE 802.11.
How does Li-Fi work?
Li-Fi is a high speed, bidirectional, and fully networked wireless communication of data using light. Li-Fi constitutes of several light bulbs that form a wireless network.
When an electrical current goes through to a LED light bulb, a stream of light (photons) emits from the lamp. LED bulbs are semiconductor devices, which means that the brightness of the light flowing through them can change at extremely high speeds. The signal is sent by modulating the light at different rates. The signal can then be received by a detector which interprets the changes in light intensity (the signal) as data. Also when the LED is ON, you transmit a digital 1, and when it is OFF, you transmit a 0.
Li-Fi Benefits
The primary benefits of Li-Fi are as follows:
• Security: Provides entirely secure access. Where there is no light there is no data.
• Safety: Does not produce electromagnetic radiation and does not interfere with existing electronic systems.
• Localisation: Allows localisation due to small coverage area of Li-Fi access point - localisation can be used for very precise asset tracking.
• Data density: Provides ubiquitous high-speed wireless access that offers substantially greater data density (data rate per unit area) than RF through high bandwidth reuse.
