A framework for sharing broadband infrastructure in South Africa : a case of rural community.

Mkhomazi, Sharol Sibongile. January 2013 (has links)
D. Tech. Computer Science and Data Processing (Business Information Systems) / The research examined the interplay between actors in the deployment of shared telecommunication infrastructures such as broadband. The study was conducted from a social context perspective, in three-fold. This includes understanding of sharing telecommunication infrastructures in rural areas; investigation of the influencing factors; and the roles of the community members. The analysis and interpretation of the empirical data revealed that the interaction amongst actors, which manifests from processes, politics and legislation are critical in the deployment of shared telecommunication infrastructures in South Africa rural areas. Based on the findings from the study, a Telecommunication Infrastructure Sharing framework was developed. The Telecommunication Infrastructure Sharing framework is aimed at guiding shared broadband deployment in the rural areas of South Africa.

A systematic framework for the evaluation of rural telecommunications infrastructure

Nepal, Thiruthlall January 2002 (has links)
submitted in partial fulfillment of the requirements for the Degree of Doctor of Technology: Information Technology, 2002. / The evaluation of telecommunications infrastructure in rural areas is a complex and messy problem that involves many tangible and intangible factors. Some of them are technical in nature while others are soft, involving social, cultural and political aspects of the problem. The evaluation requires, inter alia, societal intervention, and since societies reflect a multiplicity and diversity of values and goals, the intervention should confront these realities / D

Error monitoring for leased line data communication services

Gildenhuys, Burgert 11 February 2014 (has links)
M.Ing. (Electrical & Electronic Engineering) / This thesis investigates the problems associated with providing end to end in-service performance monitoring on leased line data networks. These problems are of both practical and theoretical nature. A solution to this problem is presented and is based on linear block coding using some overhead bandwidth available within the channel. The coding scheme relies on the characteristics of shortened cyclic codes. A method is given to obtain the undetected error probability for an arbitrary code generation polynomial with a specified degree of shortening. References to the literature explain why this type of calculation is not straightforward. This method is used to compare various candidate codes. A method is discussed which facilitates rapid isolation of groups of favourable candidate codes for further study. Software is developed to aid in the code selection process and optimum codes are selected for leased line application. It is shown that in most cases improvements in undetected error probability are achievable, when comparison is made to previously published codes, proposed for error detection. This is because code generators optimum at their published or natural coding rate are seldom optimum at the rate which results from shortening the code.

The implementation of an activity-based costing system in a service organisation with specific reference to Telkom

Tolsma, Peter 10 February 2014 (has links)
M.Com. ( Business Management) / This study wants to express an opinion on the implementation of an activity-based costing system in a service company with specific reference to Telkom SA Ltd. (hereafter Telkom), which has implemented a costing system as a first step towards an activity-based costing system. This studyis seenas a follow-up study on the work doneby Van Dyk(1993), which was also seconded to the Cost Management team within the Financial Management section of Telkom. His research paper was entitled: "Activity-based costing as a managerial control measure in a service organisation". His work in chapter one on the historical overview of accounting, the evolution of cost management systems and the description of the cost accounting system of Telkom must be seen as stepping stones on which this study will build. In chapter two Van Dyk(1993) concentrated on the influence oft he five competitive forces in the formulation of a generic strategy and the role of the value chain concept in order to understand the behaviour of costs. All of this work must be seen as the foundation and complementary to this study.

Telkom and the South African economy : achieving the optimal relationship

Baird, Peter Walther Orgell January 1995 (has links)
Includes bibliography. / South Africa needs a modern, sophisticated telecommunications network to ensure economic development and political stability. The same network must also provide affordable and reliable service to a great percentage of the population. The telecommunications industry is currently monopolised by Telkom, a state-owned business enterprise (SBE), and does not appear capable of meeting these basic requirements. The purpose of this paper is to present a case for restructuring Telkom and liberalising the telecommunications industry to best serve the needs of the South African economy. The objective for restructuring the telecommunications industry must be to maximise long-term consumer welfare for all South Africans. This paper argues that consumer welfare will be maximised only by dismantling the statutory monopoly structure and moving toward a highly competitive, privately owned telecommunications industry. The economic issues, of course, cannot be discussed realistically without reference to political, social and historical variables, all of which are also considered. By focusing primarily on economic issues, however, this paper strives to avoid the ideological disputes which usually surround discussions of state ownership. This paper focuses on the telecommunications industry because it represents the single most important infrastructural component in a modern economy. It also presents a unique opportunity if managed well, and a grave danger if allowed to continue in its current structure.

The impact of telecomunication reform on universal access in South Africa

Gregory, Angela Stuart 03 1900 (has links)
Thesis (MBA)--Stellenbosch University, 2006. / From the 1990s onwards, significant developments have occurred in the international telecommunications sector that have affected the South African telecommunications industry and peoples' access to the telephony. Rapid developments in Information and Communication Technologies together with the reorganisation of telecommunications operators through commercialisation, privatisation and market liberalisation have resulted in monopoly operators moving away from their public service mandates. Globalisation and adherence to World Trade Organisation rules are causing operators to rebalance their tariffs, long-distance rates are decreasing while the cost of local calls is increasing. High-end users of telecommunication services are benefiting while low-end, largely residential users are being priced off the network. The end result is a negative effect on universal access to telecommunications. This study examines the extent of telecommunications reform within the South African telecommunications industry as it affects the provision of telecommunication services and the government's goal of achieving universal access in South Africa. Quantitative research methods utilising secondary data were utilised to establish that the state owned operator, Telkom, has transformed itself from a public service operator to one that is fully commercialised and prepared for competition. This study finds that despite the large roll-out programme in fixed-line telecommunications, there has been only very limited uptake for rural and low-income users. Although Telkom's exclusivity period initially caused an acceleration of the growth in net new lines from Telkom's greater investment levels, this acceleration only lasted until 2000/1 when Telkom started to enforce timely accounts payment more strictly. This resulted in an actual decrease in the total number of active lines in 2001 and 2002, despite new lines being rolled out. Household figures suggest that low-income households disconnected in large numbers. Fixed line telephony access was given to people who could not afford telephones and hence they were later disconnected. The end result was that fixed lines ended up growing at a similar rate to what they were prior to the exclusivity period, suggesting that the grand subsidisation of universal access was most likely a waste of resources and only resulted in temporary ownership improvements. A further problem now faced by government is the number of people who were disconnected from Telkom and remain indebted to the company. These households are prevented from getting a fixed-line phone until they repay their deb!. This has potentially far-reaching effects on their lives through destroying their credit rating. In contrast to fixed line telephones, the growth in cellular subscribers has grown beyond all expectations. Almost all the gains in ownership have come from the adoption of cellular by rural and low-income users. This study demonstrates that cellular is the rational choice for most low-income consumers given the different tariff structures and the average monthly spend on communication. The study further suggests that future use of universal service funds should be more technology neutral, this will enhance the role of cellular telecommunications in such plans. Removing the burden off fixed line for universal service provision may enable the acceleration of telecommunication liberalisation in South Africa. Obvious benefits are better prices and products for business users. Fixed-line technology remains the core technology for business users who require bandwidth for data services and make considerably more calls than residential users, making fixed-line the cheaper technology. Amongst the current biggest users are cellular network operators. Improving prices on leasing and interconnection should lower cellular call rates, making it even more attractive to low-income users. Finally, the new Intemational Telecommunication Union definitions for universal access and service now include cellular technology and move away from a fixed-line focus. These definitions are very much in line with the results identified in this study.

Factors influencing the effectiveness of project managers in the telecommunications industry in South Africa

Ndlovu, Pholani January 2017 (has links)
Submitted in fulfillment of the requirements for the degree of Master of Management Sciences (Business Administration), Durban University of Technology, Durban, South Africa, 2017. / The South African mobile telecommunications industry has grown into a multi-billion rand industry that employs thousands of people and connects millions of people across the globe. In order to accomplish the latter, multi-million rand capital projects must be initiated and successfully executed. It is against this background that this study investigated the factors influencing the effectiveness of project managers in the telecommunications industry in South Africa. The target population of the study consisted of project managers in the five telecommunications companies in South Africa who were registered with Project Management South Africa (PMSA). The primary data, which was collected personally by the researcher through self-administered questionnaires, was analysed using the Statistical Package for Social Sciences (SPSS), Version 23. The study revealed, inter alia, that most project managers in the telecommunications industry in South Africa perceived negotiating skills, technical knowledge, and management style as being most important for effectively confronting the many challenges faced by them, inter alia, scope management, quality management, and risk management, so that projects were successfully executed. There was unanimity amongst the project managers that training in project management had a positive impact on the performance of project managers. Although three out of every four project managers possessed a postgraduate qualification, the majority of project managers were of the view that a diploma was adequate to practice as a project manager in the telecommunications industry in South Africa. However, it was more important for project managers to possess project management qualifications. In addition to the above, an analysis of the results revealed that, in order of importance, the effectiveness of the project managers in the telecommunications industry in South Africa was influenced by communication skills, technical skills, education skills, leadership skills, interpersonal skills and negotiating skills. / M

Corporate telecommunications infrastructure as a service provider for small medium and micro enterprises

Pillay, Deenasegari January 2003 (has links)
Submitted in partial fulfilment of the academic requirement for the Masters in Technology: Entrepreneurship, Durban Insititute of Technology, 2003. / South Africa has been classified as an upper-middle mcome developing country with a growth rate of 2.6%. In order to improve the quality of lives of all its citizens that includes the lowering of the unemployment rate, South Africa needs to achieve a growth rate of not less than 7%. One of the pre-requisites for economic growth is entrepreneurship. The SMME sector has been universally accepted as having the potential for generating employment and contributing to economic growth. In South Africa the SMME sector is a major contributor to the economy. Research has revealed that SMMEs fail in the first five years of start up or. stagnate in terms of development because of lack of skills, management expertise, finance and lack of basic infrastructure (such as electricity, physical premises and telecommunication). South Africa's entry into the global economy makes it imperative for businesses to have access to Information Communication Technologies regardless of the size of the business. The de-regulation of the Telecommunication Act 106 of 1996 made provision for SMMEs to provide telecommunication access to under serviced areas. This is a double-edged opportunity for the Durban Institute of Technology (M L Sultan campus) in that, the Durban Institute of Technology (M L Sultan campus) could become a Service Provider for Telecommunications access and at the same time provide SMMEs within its vicinity with Information Communication Technology access. This research outlines the various elements that a Higher Education Institution such as the Durban Institute of Technology (M L Sultan campus) needs to take into consideration for developing a Business Model to provide Information Communication Technologies to SMMEs within the vicinity of the Durban Institute of Technology. A sample of the SMMEs around the Durban Institute of Technology (M L Sultan campus) was interviewed to determine their ICT needs and their understanding of the impact of access to ICT on their business. It was found, inter-alia, that many SMMEs had no access what so ever and that there was a lack of understanding of the potential impact of ICT on their enterprise. / M

E-trust: a building block for developing valuable online platforms in Higher Education

Van Wyk, Byron Jay January 2013 (has links)
Thesis submitted in fulfilment of the requirements for the degree Master of Technology Design in the Faculty of Informatics and Design at the Cape Peninsula University of Technology Supervisor: Prof J Messeter Cape Town, 2013 / The aim of this research project was to provide an answer to the question: “How can an understanding of online trust be used to build valuable online applications in Higher Education?” In order to present an answer to this question, a literature survey was conducted to establish: • An understanding of the phenomenon of online trust • What the factors are that influence a loss of trust in the online environment The literature survey highlighted several factors that influence a loss of trust in the online environment, called trust cues. These factors, however, were often tested within the E-commerce environment, and not in organization-specific contexts, such as online platforms in use in Higher Education. In order to determine whether or not these factors would influence the development of trust in context-specific environments, the author of this research grouped the indentified trust factors into three focus areas, i.e. content, ease of use, and navigation. These factors were then incorporated into a series of nine different prototypes. These prototypes were different versions of a particular online platform currently in use at the Cape Peninsula University of Technology (CPUT). The prototypes were tested over a three week period, with certain staff members at the institution in question recruited as test participants. During each week of user observations, a different focus area was targeted, in order to establish the impact that it would have on the perceived trustworthiness of the platform in question. User observations were conducted while test participants completed a standard process using the various prototypes. Semi-structured interviews were also conducted while participants completed the specific process. Participants were asked to evaluate each screen in the process according to its perceived trust worthiness, by assigning a trust level score. At the completion of the three rounds of user observations, in-depth interviews were conducted with test participants. The participants’ trust level scores for each prototype were captured and graphed. A detailed description for the score given for a particular screen was presented on each graph. These scores were combined to provide an analysis of the focus area tested during the specific round. After the three rounds of user observations were completed, an analysis of all the trust factors tested were done. Data captured during interviews were transcribed, combined with feedback received from questionnaires, and analysed. An interpretation of the results showed that not all trust factors had a similar influence in the development of trust in the online platform under investigation. Trust cues such as content organization, clear instructions and useful content were by far the most significant trust factors, while others such as good visual design elements, professional images of products, and freedom from grammatical and typographical errors had little or no impact in the overall trustworthiness of the platform under investigation. From the analysis done it was clear that the development of trust in organization-specific contexts is significantly different than developing trust in an E-commerce environment and that factors that influence the development of trust in one context might not always be significant in another. In conclusion, it is recommended that when software applications are developed in organization-specific contexts, such as Higher Education, that trust factors such as good content organization, clear instructions and useful content be considered as the most salient. Organization-specific contexts differ quite significantly in that the users of these systems often convey a certain degree of trust toward the online platforms that they work with on a daily basis. Trust factors that are geared toward developing an initial or basic trust in a particular platform, which is often the case with first time users engaging in an E-commerce platform, would therefore not be as significant in the development of a more developed level of trust, which is what is needed within the development of organization-specific online platforms.
