Wireless Data Communication

The technologies based on the radio frequency used for wireless transmission indoor are more congested than ever these days, therefore several wireless communication alternatives are intensively searched. Some most promising technologies are based on the optical part of the electromagnetic spectrum. The benefits and drawbacks in optical wireless data communication models design are presented in this work. The key characteristics of the VLC systems are briefly discussed, as well. Some models developed for wireless data transfer in visible light communication and infrared are presented, and their operation related to the data rate and the length of the optical link, are briefly compared.

Abstract: A major issue in public places like shopping malls, museums and hospitals is parking. Parking is the main service used by the people in these private units. The management of these public units invests more time and money in designing parking systems. Existing parking systems are equipped with appropriate sensors and controllers to count the parked cars automatically, but it does not indicate empty parking slots. These systems consume more power and tend to wireless interference. The proposed system, namely, Visible Light Communication based Smart Parking System introduces Visible Light Communication, a data communication technology using a low power Arduino Uno – Atmega328microcontroller to help drivers to get real-time parking information. Real-time information on free parking slots helps drivers to save time and reduce fuel consumption. Visible Light Communication (VLC) or Li Fi or Optical Wireless technology means the wireless data transfer using LED. Wireless interference is greatly reduced by using VLC. The proposed system is suitable for multiple floor buildings, which involves data gathering from parking side modules integrated in multiple floors of the building. Parking side modules continuously collects the data and intimates the module integrated in the vehicle section. The module in the vehicle section interfaces a GSM modem to send the detected information to the user mobile. The result of the proposed system is validated in an indoor environment.

Visible Light Communication (VLC) technology allows wireless data transmission piggybacked by illumination. Highly accurate and reliable systems based on VLC, as Indoor Positioning System (IPS) have been already developed by academics and specialized companies. Underground Positioning System (UPS) addressed here is embedded into the protection equipment, compulsory to be used underground, being therefore important to workers in potential dangerous spaces since fast data communication and real-time data interpretation is therefore possible. This paper presents the VLC technology implemented in mining underground specific environment for an accurate positioning and fast data communication for underground navigation with the main aim of developing a real time warning and alarming system based on Augmented Reality (AR) and Neural Networks (NNs) principles.

LiFi is a wireless optical networking technology that uses light-emitting diodes (LEDs) for data transmission. LiFi is designed to use LED light bulbs similar to those currently in use in many energy-conscious homes and offices. LiFi data is transmitted by the LED bulbs and received by photoreceptors. Li-Fi technology transmits data at very high speed and is capable of delivering 224GB of data per second. Furthermore, it offers better security as compared to Wi-Fi. Due to its high speed, Li-Fi technology can be widely used in electromagnetic sensitive areas, such as, hospitals, airplanes, and nuclear power plants. Light Fidelity (Li-Fi) is a data transfer technique that uses light. Light is analogous not only to illumination but also to speed. Li-Fi is also much secured since light cannot pass through walls. It uses visible light portion of the electromagnetic spectrum to transmit information. Hence the visible light communication solves the problem of radio frequency congestion. In this project we transmit data and audio through light at very high data rates without use of microcontrollers and its other peripheral devices.

The spectrum crunch in Radio Frequency (RF) Communication and the prospect of Visible Light Communication (VLC) as an alternative to RF has made way for high speed VLC deployment. The ubiquitous coverage of RF and the high speed data rate achieved with VLC, make the two technologies complimentary to each other, making the hybrid RF/VLC an emerging trend in wireless networks. This study presents a downlink communication of a hybrid RF-VLC, where the signal received through RF channel by a relay is decoded and the symbols are converted into an electrical signals. The electrical signal is fed to an array of LEDs in the relay where data is transmitted in rays of light from LEDs. The hybrid RFVLC system performance is compared with a conventional RF system to understand the performance difference between the two communication models. Thus, the performance of both system models are analysed in terms of Symbol Error Rate and Outage Probability. Numerical results show that the proposed hybrid RF-VLC system is superior to conventional lone RF cooperative system.
