A Review: Evolution of 5G, Security and Multiple Access schemes in Mobile Communication

5G wireless communication is a next generation technology that is set to beat 4G LTE and provide maximum internet speed (Gbps) and high base station capacity. The need for 5G is due to the multiplying increase of smart phones and instantaneous data, introduction of fresh evolving multimedia applications. Security has also been and will be a vital issue in mobile communication systems, especially in key production processes and mobile users’ authentication. In this paper, I intend to make a review of the evolution of wireless communication towards 5G networks alongside key production solutions and authentications and also discuss the different types of multiple access schemes and comparisons used in mobile communication

Design and Simulation of a Smart Traffic System in a Campus Community.

Road traffic within campus communities has increased tremendously. More persons are now moving around campuses with vehicles than previously recorded. This development will pose a major traffic challenge if it is not addressed urgently. Standard technologies for traffic management in campus communities do not have a computerized framework that can control traffic based on detected level of congestion. The main purpose of this research is to propose a more efficient and effective system for road traffic management in a campus community. The system is completely automated and can manage the ever mounting traffic in campus communities. The proposed campus traffic management system was simulated using Proteus®. Tests carried out on the simulated reallife campus traffic scenario confirmed that the proposed campus traffic management system was better than conventional traffic control systems in existence on campuses

Comparative Analysis of the Effect of Distance on Signal Strength using Selected Communication Media

This paper presents an investigation of the effect of distance on communication via optical fibre single mode and multimode structure. It also gives a comparative analysis of transmission over radio wave and fibre optic links. First, data were collected at different distances in the multimode and single mode optic fibre link, recorded and analyzed. Secondly, data was taken and compared to multimode fibre optic and microwave (18GHz) links. It was observed that communication through multimode optic fibre link degraded noticeably with the increase in distance in comparison with the single mode optic fibre link. In comparison with the 18GHhz microwave link, the multimode fibre optic link performed better as a communication medium. This information is especially useful for making critical decisions for the deployment of future communication infrastructure

IoT-Enabled Alcohol Detection System for Road Transportation Safety in Smart City

In this paper, an alcohol detection system was developed for road transportation safety in smart city using Internet of Things (IoT) technology. Two Blood Alcohol Content (BAC) thresholds are set and monitored with the use of a microcontroller. When the first threshold is reached, the developed system transmits the BAC level of the driver and the position coordinates of the vehicle to the central monitoring unit. At the reach of the second BAC threshold, the IoT-enabled alcohol detection system shuts down the vehicle’s engine, triggers an alarm and puts on the warning light indicator. A prototype of this scenario is designed and implemented such that a Direct Current (DC) motor acted as the vehicle’s engine while a push button served as its ignition system. The efficiency of this system is tested to ensure proper functionality. The deployment of this system will help in reducing the incidence of drunk driving related road accidents in smart cities
