LiFi Technology

Everything you have to know about LiFi

What is LiFi?

LiFi is a high-speed, bidirectional and fully networked light communication solution. LiFi technology uses light instead of radio waves to transfer data, embedding the information in beams of light. Our LiFi-enabled devices convert these beams into an electrical signal, which are then converted back into data.

We provide LED lighting solutions with the required LiFi hardware and software components installed. Customers simply plug a LiFi dongle into their laptop which automatically connects via the light beam to the nearest LiFi LED light. The device can now receive and transfer data up to 100x faster than WiFi – and with 100% security.

How does it work?

LiFi is a communication technology based on the principles of Visible Light Communication (VLC).  A LED lamp is switched – using binary code – between logical states of “1” and “0”.   Just like a computer. Using this principle, chains of information can be sent at high speed, undetectable by the human eye.

The photodiodes, which convert the light into an electrical current, have an ultrafast response time. As a result, they can register minute changes in light intensity and convert this information into binary electrical signals that can be decoded by the detection device. In this way, the received information is shared with the user.

LiFi and Ellipz LED Technology

99% of the world’s LED lamps are blue chip LEDs which use phosphor to make white light – yet phosphor slows the response time. Ellipz Lighting ensures a rapid response by keeping the layer of phosphor as thin as possible or using no phosphor at all. That’s why, with Ellipz, the LiFi connection is 50% faster than any other LiFi infrastructure.

Another advantage of Ellipz is the stability of the connection. By only using LEDs which have wavelengths similar to the ones recommended for a LiFi receiver, we maximise the sensibility and mobility of the LiFi receiver, improving connectivity.

Solutions

LiFi Glider

Our LiFi Glider enables highly accurate indoor navigation. We are able to micro-locate personal devices to help us track or navigate them accurately. We use ‘geofencing’: this technology creates virtual boundaries which trigger a response in our software when devices enter or leave the defined area.

LiFi Bridge

Our LiFi Bridge is bidirectional and has, in addition to the geolocation characteristics of our LiFi Glider solution, another functionality:

The exchange of data between two objects/devices via LiFi, allowing high-speed streaming of data via light.

LiFi Spotter

Our LiFi Spotter provides a smart solution for precise indoor geolocation. With LiFi, it is possible to have Two-Way Communication (send and receive data) as long as you’re in the light beam. Data can be transmitted to and from devices via light, enabling a stable connection.

Products

Modulator

The modulator is a crucial part of hardware that enables our LiFi lamps to share internet data.

An ethernet (internet) cable is connected to the modulator, which then transforms the data in a way that enables the LiFi lamp to send and receive information through light.

Dongle

A dongle is a small piece of hardware that allows users to communicate with the LiFi lamps. After the modulator has transformed the data into a form that can be sent using the lamp’s light spectrum, the dongle is needed to pick up that signal and translate it into data for the devices. The dongle is also used to send information back to the lamp, functioning as an uplink during the streaming.

Software

The software we’ve created allows our customers to interact with and manage the data communication between the LiFi lamps and the users.

Things such as position tracking, permissioning, push marketing and – more importantly – making sense of data collection, are managed through a software system.
