H2020 project ” Internet of Radio Light”
contact: xun.zhang at isep.fr
Wireless networks in buildings suffer from congestion, interference, security and safety concerns, restricted propagation and poor in-door location accuracy.
The Internet of Radio-Light (IoRL) project develops a safer, more secure, customizable and intelligent building network that reliably delivers increased throughput (greater than 10Gbps) from access points pervasively located within buildings, whilst minimizing interference and harmful EM exposure and providing location accuracy of less than 10 cm. It thereby shows how to solve the problem of broadband wireless access in buildings and promotes the establishment of a global standard in ITU.
IoRL project designs a Remote Radio-Light Head (RRLH), so that it can easily be installed in a wide range of different types of properties and Network Management & Operations Plane API for buildings where third party application developers can develop and exhibit their innovative network services in homes, businesses and public space buildings using open source development environment. Example services will be developed in the project such as one that ameliorates the need for using HeNB/HgNB or WLAN in buildings and eliminates the uplink interference that they induce. This will have the effect of incentivising all building construction companies to install an RRLH throughout their new build developments. Building landlords will be incentivized to find funding to realize this solution for their properties to increase their value resulting in a stimulated market for broadband networking products in buildings, benefiting society and stimulating the world Gross Domestic Product. Thus there are four use case scenarios for the most important type of buildings: homes, public spaces – museums, shopping malls and metro stations.
TECHNICAL AND RESEARCH CHALLENGES
The challenges are to (i) Develop broadband communication solutions for buildings by integrating VLC, mmWave and SDN/NFV technologies to exploit the pervasiveness and accessibility of the existing electric light access points, the broadband capacities of mmWave and VLC technologies and the flexibility of SDN/NFV; (ii) Industrially design a remote radio-light head solution that can be integrated into the myriad of form factors of existing electric light systems and consumer products.

Usage of light emitting diode (LED) is rapidly growing due to its reliability, low power consumption and high efficiency. In Visible Light Communication (VLC) system, LED is used for illumination simultaneously its can be used for communication. The objective of this project is to study the VLC system and design a prototype to demonstrate the functionality of VLC system for audio and digital signal transmission through modulated LED light beam. The VLC system consist of two main components which are transmitter and receiver. The transmitter is attached with LED and the receiver is attached with photodiode, such that, the signal can be transmit through LED and receive by Photodiode. The design of the VLC system involved idea of generating negative voltage, signal amplification, compensating background light intensity, recovering attenuated signal.
