Abstract The dissipation of information is an essential aspect of any community. The advent of media services such as television and radio has improved the way information has been broadcasted to the general public. Unfortunately in Zimbabwe Universities, these services have not yet been utilized. This Dissertation illustrates a prototype of campus radio streaming system over an intranet. This is to provide local universities with a cheaper alternative to providing a local radio station compa...
ABSTRACT Prior studies have identified many problems of having poor water sanitation system. The major problem being rise of water-borne diseases. This thesis is an advancement to an argument that the leading root cause of the water-borne disease outbreaks in Zimbabwe was the unsustainable urban environmental practice especially in the water reticulation system. The overarching purpose of this project is to give a solution to a case in which the failure in proper water reticulation system in ...
ABSTRACT Home/ Bank/ Office security has been a major issue where crime is increasing and everybody wants to take proper measures to prevent intrusion. The project is aimed at developing the security of home against Intruders. In a case of intrusion while the user is out of the house, then the device sends SMS to the emergency number provided to it and also display it on LCD connected to it. The paper consists of a background into the area At mega 2560 microcontroller, sensing elements and GS...
ABSTRACT People living in rural areas need broadband connection for services such as e-governance, virtual class rooms, telemedicine, video-on-demand, home entertainment. Therefore, the need for high speed broadband connection in rural areas is inevitable. However, in order to provide broadband services, service providers must incur high deployment cost and wait for a long time for return on investments. Long Term Evolution (LTE) has been proposed to overcome high deployment cost, although ...
Abstract There has been an emerging demand for quick and easy payment of bills in supermarkets. This project describes how to build an automated and time saving system for the world of retail which will make shopping experience impetuous, customer friendly and secure. In this dissertation, RFID based electronic is proposed that will be capable of generating a bill from the cart itself. The designed trolley helps the shop owner by reducing the shop assistances available on duty at one time th...
ABSTRACT The purpose of the study was to implement a frequency reuse in 3GPP-LTE downlink cellular system which was to be used as the main measurement and as analysis tool for interference mitigation and to evaluate the performance for various conditions enabling the efficient deployment and optimization of femto cells on multi-tier networks. The Mat Lab Vienna LTE simulator was used to analyses the degrading impact of interference on channel capacity when Femto-cells are deployed over a Macr...
ABSTRACT Telecommunications companies, over the last decade, have undergone major change in terms of the manner in which they do business. The objective of this study was to investigate the impact of change implementation on staff turnover in telecommunications industry by reviewing the following key issues, the effect of change implementation on staff turnover, the implementation of change within the industry, the communication of change initiatives by management in the industry, and the eff...
Abstract Pedestrian visitors at Gweru General Hospital are facing challenges crossing the Shurugwi road into the hospital premises due to high vehicular traffic influx to and from town. Thus this Arduino based pedestrian crossing control system has been designed to give priority to these pedestrians so that they can safely cross this perilous main road. The system incorporates the concept of passive pedestrian detection to sense the presence of pedestrians and in turn automatically controls t...
Abstract Voice over Internet Protocol (VoIP) is one of the most important technologies in the world of communication.Mass business sector VoIP telephony started in 2004 with the presentation of VoIP calling arrangements which allowed endorsers of make calls generally as they would with traditional phone organization administrations [1]. VoIP is the steering of voice conversation over the Internet or some other IP-based system [2]. The voice information streams over a broadly useful parcel exc...
ABSTRACT The unavailability of strong technologies in the police force as far as traffic offenses are concerned has led to many law violators going unpunished, and the root cause of this is the limitation that all traffic road blocks around the country are totally dependent on human effort or power. The need for cheaper, smarter and efficient traffic monitoring system facilities in the police force has brought to introduction of small unmanned copters that can execute human tasks with less re...
ABSTRACT The issue of EMF radiation has for years been received with mixed feelings by all stakeholders. In this study, the relationship between EMF exposure levels with distance from the mobile base station has been illustrated. The contributions of each frequency band used by mobile operators in Zimbabwe, with reference to the area of study has been assessed and compared using well informed data and assumptions. Graphs have been used to clearly show such contributions and matlab was used fo...
Abstract In the last half decade data traffic has surpassed voice traffic in telecommunications networks. Legacy networks could not cope with the overwhelming data traffic and exponential increase in subscribers. To address legacy systems limitations in this regard 4G LTE was introduced. With reduced network elements and advanced robust modulation technologies 4th generation systems offer data speeds much more than 3G and wired networks. In addition, 4G offers a variety of services which coul...
Abstract This research work studied the behaviour of Africom’s converged network, measured and evaluated the QoS of service of the network with the various traffic streams. Its objective was to identify and measure the different metrics that affect the delivery of QoS in the network. Parameters for measuring QoS were be identified and measured and the overall performance of the network evaluated. The approach that was adopted was guided by the subscriber concerns as well as the technical pa...
ABSTRACT This report serves to give an account for a research on a Public Transport Inventory Monitoring System for Developing Countries. The research is based on the current situation in Zimbabwe where the public transport industry is dominated by the informal sector. In this document there is a discussion of the transport industry in Zimbabwe, identification of the problem of accountability of inventory in the current industry, a methodology to help solve the problem and the results of usin...
Abstract In Zimbabwe television (ZTV) transmission coverage is approximately 55% nationwide and is mainly confined to urban areas. The dissertation overviews activities of the author’s design of a solar tv transmitter prototype which will act as gap filler in remote areas where there is no television coverage. Due to recent progress in the field of Wireless Sensor Networks (WSN) in industry particularly for control and data processing, the same goal can be achieved in television broadcastin...
