  • Aderonmu, AI; Rotimi, AH; Masonta, Moshe T; Mzyece, M (Springer, 2012-11)
    Radio Frequency (RF) spectrum is a natural resource widely used by wireless network operators to provide radio communications or transmission systems (e.g. telephone operators and TV broadcast stations). Scarcity of RF ...
  • Roux, K (2007-05)
    In countries where cable infrastructure is lacking, satellite communications is often the preferred alternative to reach the mass market. Interactive video-on-demand requires a large amount of bandwidth per subscriber, ...
  • Von Staden, R; Roux, K (2009-10)
    The Meraka Institute, together with its partners, have undertaken an ambitious task to provide broadband connectivity to under-served areas of South Africa through a community centric model, as opposed to a typical national ...
  • Pejovic, V; Johnson, DL; Zheleva, M; Belding, EM; Lysko, Albert A (Springer International Publishing, 2015)
    Internet connectivity is available to merely 39% of the world’s population. Lack of internet access is primarily restricted to developing regions, however, many remote communities in the developed world are currently ...
  • Pejovic, V; Johnson, DL; Zheleva, M; Belding, EM; Lysko, Albert A (2014-01)
    White spaces promise to revolutionize the way wireless connectivity is delivered over wide areas. However, large-scale white space networks face the problem of allocating channels to multiple contending users in the wide ...
  • Masonta, Moshe T; Johnson, D; Mzyece, M (Springer, 2011-11)
    The global migration of television (TV) from analogue to digital broadcasting will result in more spectrum bands (known as TV white space), previously used in analogue broadcasting, becoming available and unoccupied. A ...
  • Abu-Mahfouz, Adnan MI; Isaac, Sherrin J; Kruger, Carel P; Niels Aakvaag, N; Britta Fismen, B (IEEE Xplore, 2014-04)
    Approximately 70% of South African mines are classified as fiery, where methane gas potentially could cause explosions. The number of flammable gas reports and accidents are increasing steadily for both gold and platinum ...
  • Molefi, M; Markus, ED; Abu-Mahfouz, Adnan MI (IEEE, 2019-06)
    LPWANs are emerging to provide solutions for covering very low-power Internet of Things devices and applications which may be distributed over large geographical areas. LPWANs generally consume very low power thus their ...
  • Abu-Mahfouz, Adnan MI (2012-10)
    MI2T-WSN is a multi-level infrastructure of interconnected testbeds of large-scale WSNs. MI2T-WSN consists of 1000 sensor motes that will be distributed into four different testbeds. The variations of these testbeds will ...
  • Adedeji, K; Hamam, Y; Abe, B; Abu-Mahfouz, Adnan MI (http://www.satnac.org.za, 2016-09)
    With increasing population in South Africa coupled with improved standard of living, the demand for water has increased dramatically in the past few years. To meet this demand and for effective water supply, the water loss ...
  • Dludla, Angeline G; Abu-Mahfouz, Adnan MI; Kruger, Carel P; Isaac, John S (IST Africa 2013 Conference Proceedings, 2013-05)
    Wireless sensor networks (WSNs) have been used in different types of applications and deployed within various environments. Simulation tools are essential for studying WSNs, especially for exploring large-scale networks. ...
  • Zlobinsky, Natasha; Johnson, David (2016-09)
    The concept behind this work is to build mesh net-works in the TVWS band for developing regions to improve internet access opportunities. The purpose is to solve a pertinent problem within the context, namely to find an ...
  • Lysko, Albert A (IEEE, 2016-07)
    There is a need for work around improving frequency spectrum utilization efficiency to support the South African government targets of 100% broadband by 2020, with tough specifications stated by the National Broadband ...
