LiFi Towards 5G: Concepts, Challenges, Applications in Telemedecine

EasyChair Preprint no. 4089

5 pagesDate: August 25, 2020


In recent years, the number of devices, applications and services based on a wireless connectivity has grown exponentially resulting in deep changes in our ways of living. New concepts such as the Internet of Things (IoT) associated with the connectivity of sensors and machines will amplify this phenomenon. The term "wireless" refers primarily to radio frequencies (30KHz to 300GHz), the main challenge is the saturation of the spectrum electromagnetic. In this paper, we give a survey of the most significant issues Li-Fi (Light Fidelity) systems that operate at short ranges. We consider the challenging issues facing these systems: link design and system requirements, transmitter and receiver structures, challenges and possible techniques to mitigate the impairments in these systems, applications in medicine and open research issues. In Li-Fi, the data are transmitted in several bit-streams flickering of the LED bulb and decoded on the receiver side. This happens in the form of a binary transmission of data, where ‘0’ is the LED in its ‘off-state’ and ‘1’ is the LED in its ‘on-state’. we use this concept to transmit data (audio signal) to demonstrate the use-cases and the possible impact it can have in the ever growing field of communication.
