Together we build the LiFi ecosystem

Standards-based, multi-vendor ecosystem. Every day, we do amazing things with light. Where there’s light… there can be wireless communication through LiFi. Within Signify, I am responsible for building a worldwide, cross-industry ecosystem around this latest innovation in lighting. Fast, reliable and safe data communication not using RF but light. How cool is that !?!

Optical Camera Communication, a wireless communication between LED Light and camera of the phone (image sensor) for usage of b2b2c

OCC technology that stands for Optical Camera Communication is a one-way communication flow between an LED lamp and a smartphone.
This allows for glocalization with ultra-precision limited strictly and securely to the beam of the LED. It detects the presence of a user under a specific light at a live timeframe.

Light Communication as a part of 5G and Beyond

deepak solanki

With internet users growing by the minute, comes the great challenge of ensuring faster speeds and higher bandwidths. 5G, the next wireless revolution, comes as a solution that can cater to the endlessly growing base of users. But 5G infrastructure requires denser deployments of small cells within cities having high backhaul capacity. The fibre optic cables can meet this demand but rolling out an extensive fibre network poses deployment complications. Laying down fibre is time consuming and costly process and makes expansion near impossible specifically in developing nations.

What is Li-Fi?

According to Wikipedia: Li-Fi (ˈlaɪfaɪ; short for light fidelity) is wireless communication technology, which utilizes light to transmit data and position between devices.

In technical terms, Li-Fi is a light communication system (hence based on photonics) that is capable of transmitting data at high speeds over the visible light, ultraviolet, and infrared spectrums. In its present state, only LED lamps can be used for the transmission of visible light.

In terms of its end use, the technology is similar to Wi-Fi – the key technical difference being that Wi-Fi uses radio frequency to transmit data.

Optical wireless communications technologies for the internet of things

by Dominic O’Brien, Professor of Engineering Science, Department of Engineering Science, University of Oxford

The Internet of Things (IoT) presents a wide range of implementation challenges, including ensuring security, lowering energy consumption, and providing reliable communications. Optical Wireless Communications (OWC) and LiFi can assist in achieving this, and provide secure contained communications channels, energy that can be harvested by IoT nodes, and critically; new regions of the electromagnetic spectrum to alleviate the demands on the congested RF spectrum.

LuxSenz: Exploiting Sunlight for Wireless Communication

Marco Zuniga

by Marco Zuniga, TU Delft (Network and Embedded Systems Group)

In this information age, communication is central to our societies but it is taking a toll on the earth. As reported by Time Magazine, by 2013, we were already using 50% more energy moving bytes than moving airplanes around the world. Our societies face a major challenge: How can we satisfy our ever-growing demand for communication but in a sustainable manner?
