Radio Frequency Identification (Rfid) Based Electronic Shopping Trolley

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 ti...

Frequency Reuse In 3gpp-Lte Downlink Celluar System

ABSTRACTThe purpose of the study was to implement a frequency reuse in 3GPP-LTE downlink cellularsystem which was to be used as the main measurement and as analysis tool for interference mitigationand to evaluate the performance for various conditions enabling the efficient deploymentand optimization of femto cells on multi-tier networks. The Mat Lab Vienna LTE simulator wasused to analyses the degrading impact of interference on channel capacity when Femto-cells aredeployed over a Macro-cell...

The Impact Of Implementation Of Change Management Processes On Staff Turnover: A Case Of Zimbabwe Telecommunications Industry

ABSTRACTTelecommunications 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 effe...

Arduino Based Pedestrian Crossing Control System For Gweru General Hospital

AbstractPedestrian 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 th...

The effects of Security mechanisms on VoIP communication Quality of Service

AbstractVoice 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 exch...

Dynamic Quadrotor Traffic Offense Monitoring System

ABSTRACTThe 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 res...

A Model To Determine Safe Zone Margin For Mobile Base Station Sites In Residential Areas With Reference To Emarald Hill And Greencroft Residences, Harare, Zimbabwe

ABSTRACTThe 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 for...

Evolving 4G KPIs to improve end user QoE for 4G LTE broadband systems.

AbstractIn 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 could...

Quality Of Service Measurement And Evaluation In Telecommunications: A Case Study Of Africom (Private) Limited

AbstractThis research work studied the behaviour of Africom’s converged network,measured and evaluated the QoS of service of the network with the various trafficstreams. Its objective was to identify and measure the different metrics that affectthe delivery of QoS in the network. Parameters for measuring QoS were be identifiedand measured and the overall performance of the network evaluated. The approachthat was adopted was guided by the subscriber concerns as well as the technicalparameter...

Public Transport Inventory Monitoring System for Developing Countries

ABSTRACTThis 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 using...

Design and construction of a low cost solar TV transmitter

AbstractIn Zimbabwe television (ZTV) transmission coverage is approximately 55% nationwide andis mainly confined to urban areas. The dissertation overviews activities of the author’s designof a solar tv transmitter prototype which will act as gap filler in remote areas where there isno 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 achievedin television broadcasting by h...

Critical Study Of Bandwidth Management Strategies For Internet Services [Case Study Midlands State University]

ABSTRACTThe internet has become a key resource at Midlands State University for research and communication. The institution is also experiencing high students‟ population which in turn has led to more demand for bandwidth. The high students‟ population makes the overall available bandwidth shrink leading to slow internet connection making internet an ineffective academic resource. The institution has been responding to slow internet connection by buying more bandwidth which is so uneconom...

Mobile Phone Based Scada System

ABSTRACTMonitoring is very important in Industrial Automation to bring out reliability and accuracy thus the use of a SCADA system.SCADA is an acronym for “Supervisory Control and Data Acquisition.” This systems arewidely used in industry for supervisory control and data acquisition of industrial processes. AAndroid-enabled mobile phone can be used as a client in a SCADA application in order to display and supervise an industrial refrigeration system. The project presents an actual implem...

The Impact Of Network Outage On Value Added Services: A Case Study Of M-Pesa In Ilala Municipal In Dar Es Salaam

ABSTRACT The study was aimed at assessing the impact of network outage on the Value Added Services (VAS) particularly Mobile-Pesa (M-Pesa) among other (VAS) offered by Vodacom network operator in Tanzania. The study was conducted in Ilala municipal in Dar es Salaam Tanzania. The basic parameters used to assess the network availability were Mean Time To Repair (MTTR), Call Setup Success Rate (CSSR) and Total User Outage Time (TUOT). The parameters like the time to get response from the ...

Comparative Analysis On Reception Of Digital Video Broadcast-Terrestrial: A Case Study Of Arusha City

ABSTRACT Tanzania has been among the earliest countries in Africa to employ Digital Video Broadcast-Terrestrial (DVB-T) System. The deadline for Analogue Switch Off (ASO) was set to be in 2015, but Tanzania decided to have phased switch off since 2010. DVB-T is a new system in Tanzania and hence the extent of quality of the signal needs to be established. This research compares the reception of DVB-T second generation spatial signal strength as offered by Star Media Limited, Agape ...
