What is LiFi?
Wireless, fast, secure
LiFi, short for Light Fidelity, revolutionizes communication with its bi-directional optical technology, empowering lightning-fast data transfers without relying on radio waves.
LiFi is a cutting-edge technology that transforms light into data through the modulation of an LED-emitted light signal, invisible to the naked eye.
The signal flows between a transmitter device (Access Point or Repeater Antenna) with LED bulbs and a receiver (Dongle) connected to devices. Although an external receiver is still necessary for most devices, PhotonFi offers the first tablet casing with an integrated LiFi receiver.
Thanks to ongoing miniaturization efforts, LiFi technology is on track to be seamlessly integrated into all devices (computers, smartphones, tablets, etc.) in the near future. With its attributes of ultra-fast, healthy, stable, and secure connectivity, LiFi is emerging as a flagship technology in the realm of telecommunications.
The advantages of LiFi
Achieve up to a 50% reduction in energy consumption compared to Wi-Fi.
Unlike WiFi, which relies on energy-intensive devices like routers, modems, and repeaters that are typically left on continuously, LiFi leverages the energy efficiency of LED technology. This results in lower overall energy consumption, offering potential cost savings on electricity bills and reducing carbon emissions.
High-speed and reliable connectivity for multi-gigabit speeds.
Due to the visible light spectrum being 10,000 times broader than radio waves, LiFi can transport a significantly larger volume of data within a given time compared to WiFi. Beyond its economic and ecological merits, PhotonFi’s LiFi solutions exhibit exceptional efficiency, offering speeds of up to 5 Gbps. This high-speed connection allows users to fully capitalize on internet capabilities, including downloading, streaming, video games, online courses, collaborative tools, and more, as well as facilitating point-to-point data transmission.
LiFi guarantees unparalleled security by implementing data partitioning within the broadcasted area.
In an era where critical business operations rely heavily on electronic handling, cybersecurity emerges as a significant concern that current technologies haven’t definitively addressed. Historical evidence shows that WiFi’s radio waves, capable of penetrating walls, compromise the absolute security needed by governments, law firms, and embassies when handling confidential files. Our optical communication solutions transmit data through light, confining it to a defined area and enabling a connection strictly limited to the installation space. Essentially, LiFi is interception-resistant, offering an exceptionally robust cybersecurity solution.
A wireless and compact technology that substitutes conventional cables.
LiFi, by virtue of its direct integration into infrastructures, reduces the need for cumbersome cable installations. This innovative technology eliminates the traditional reliance on extensive cable clusters, offering a more streamlined and aesthetically pleasing solution. Beyond aesthetics, LiFi’s cable-free design brings about practical benefits, particularly in sectors where safety and efficiency are paramount.
Safe data transmission system by avoiding the use of radio waves.
LiFi connectivity, as it doesn’t rely on radio waves, emerges as a completely harmless alternative, offering a definitive solution to a central concern in the future of Internet connections. The ubiquitous nature of radio waves in our daily lives is prompting increasing issues. While the impact of prolonged exposure to radio waves on the brain and disease development remains undefined, it raises concerns. The demand for a connectivity solution devoid of radio frequency pollution is growing for both health and safety reasons.
PhotonFi LiFi
How does it work?
Our LiFiMAX Access Point manages, converts, and encrypts the network signal from modems, servers, and hotspots into beams of infrared light that are picked up by the LiFi transceivers and converted back into data that the device can use. The LiFi system also allows VLAN management from the user’s LAN to be passed through to ensure additional device-specific preferences.
ACCESS POINT & ANTENNA
LiFi system management
The Access Point refers to a LiFi router linked to the Internet via a PoE-enabled RJ45 Ethernet cable, seamlessly integrated into an the antennas. The Access Point receives network information as an electrical signal, which is then translated through the modulation of the LED within the antennas. Emitting a light beam with an intensity that fluctuates tens of thousands of times per second, this oscillation is so rapid that it remains imperceptible to the naked eye. The LED emits a light beam whose intensity varies tens of thousands of times per second, so fast that this oscillation is perfectly invisible to the naked eye.
LIFI DONGLE
LiFi signal reception and processing
The device linked to the dongle or equipped with the integrated LiFi chip, when situated within the light beam’s coverage area, captures data transmitted through light oscillation. The Dongle facilitates the reception and processing of data through its inclusion of a photodiode that captures the light signal. A processor within the Dongle then translates this signal into a binary system, making it comprehensible to computers, smartphones, or tablets.
LiFi use cases
Board Rooms & Offices
PhotonFi reduces the risk of data leaks, increases usable internet speeds on devices, and ensures only approved devices can access sensitive information.
In fixed environments (buildings, offices, laboratories or other large spaces), LiFiMAX offers users the advantages of mobile connectivity and avoids the ergonomic constraints of cable while enjoying optimal security.
Esports & Gaming
PhotonFi reduces latency while increasing flexibility at the arena, in the training facility, and at home. Our LiFi system prevents the need to run cables to the PCs and brings ultra-low latency with guaranteed speeds to your battle stations and practice areas.
By minimizing the requirement of running cables and managing latency for each device on the network, Esports organizations and arenas can ensure fair play while saving costs and minimizing cables.
Radio Frequency Free
RF-free environments are particularly crucial for businesses and industries where the presence of radio frequency (RF) signals can interfere with sensitive equipment, compromise security, or pose health concerns. Our LiFi solutions can support healthcare facilities, research labs, manufacturing, data centers, government facilities, financial institutions, and aerospace and defense connect wirelessly without the risk of radio frequencies damaging their equipment or interfering with mission-critical processes.
Education
The integration of digital technology in school education is expanding, opening up new learning possibilities. However, apprehensions regarding the effects of radio waves on students have prompted stringent regulations on WiFi usage in educational settings. Positioned as an ideal and health-conscious alternative, LiFi in schools distinguishes itself not only for its absence of radio waves but also for its seamless ability to support multiple users simultaneously without latency. Furthermore, LiFi’s space-saving characteristics enable effortless integration into existing lighting systems.
