Author: Mamushiane, Lusani ; Lysko, Albert A ; Kobo, Hlabishi I ; Mwangama, J Date: Aug 2023 Field trials and experimentation are crucial for accelerating the adoption of standalone (SA) 5G in Africa. Traditionally, only network operators and vendors had the opportunity for practical experimentation due to proprietary systems and ... Read more
Dynamic spectrum allocation for TVWS wireless access from high altitude platform

Author: Hussien, HM ; Katzis, K ; Mfupe, Luzango P Date: Dec 2021 The issue of spectrum allocation in cognitive high altitude platform wireless networks using TV White Space (TVWS) spectrum is presented in this paper. The mathematical model of spectrum allocation is given, and this model is converted into ... Read more
Experience in profiling and optimizing a 5G standAlone Radio Access Network (RAN) based on an open source testbed

Author: Mamushiane, Lusani ; Lysko, Albert A ; Mwangama, J ; Kobo, Hlabishi I ; Otieno, HO Date: Aug 2023 The adoption of 5G technology in Africa has been increasing steadily, with initial emphasis on non-standalone (NSA) architecture to leverage existing 4G investments and accelerate return on investment. The uptake of standalone (SA) 5G has ... Read more
Innovating for Broadband: The Case of Television White Space Networks in Sub-Saharan Africa

Author: Mzyece, M ; Mfupe, Luzango P ; Mekuria, Fisseha Date: Nov 2018 Television white space (TVWS) networks based on geo-location spectrum databases (GLSDs) present an excellent opportunity to provide affordable broadband to underserved rural communities in Sub-Saharan Africa. In this paper, we explore potential ... Read more
Integration of massive MIMO and machine learning in the present and future of power consumption in wireless networks: A review

Author: Nwachukwu, SE ; Chepkoech, M ; Lysko, Albert A ; Awodele, K ; Mwangama, J ; Burger, Chris R Date: Aug 2022 The steady increase in data traffic rates and systems’ complexity have contributed to the information and communication technologies (ICT) sector’s increased energy consumption and CO 2 emissions. These pose a significant challenge to the ... Read more

Metaheuristic optimisation for radio interface-constrained channel assignment in a hybrid Wi-Fi–Dynamic Spectrum Access wireless mesh network

Author: Zlobinsky, N ; Johnson, D ; Mishra, AK ; Lysko, Albert A Date: Dec 2021 Channel Assignment (CA) in wireless mesh networks (WMNs) has not been well studied in scenarios where the network uses Dynamic Spectrum Access (DSA). This work aims to fill some of this gap. We compare metaheuristic algorithms for optimising ... Read more
Proceedings of IEEE AFRICON 2021, Arusha, Tanzania, Virtual Conference, 13-15 September 2021

Author: Mfupe, Luzango P ; Kaijage, S ; Mwangama, J ; Oyerinde, O ; Katzis, K Date: Sep 2021 AFRICON is the Institute of Electronics and Electrical Engineers (IEEE) Region 8 flagship conference on the African continent. IEEE AFRICON 2021 was virtually held in Arusha, Tanzania from Monday the 13th to Wednesday the 15th of September ... Read more
Real-time spectrum occupancy measurements based on the energy detection method in cognitive radios

Author: Lebese, J ; Olwal, T ; Mfupe, Luzango P Date: Sep 2021 Spectrum occupancy measurements have become vital due to the proliferation of radio users. Literature shows that most of the allocated spectrum is used sporadically. This brings in the idea of dynamic spectrum access techniques using Cognitive ... Read more
Software tools for power consumption monitoring of open 5G and beyond research: A review

Author: Ebrahim, Rozeena ; Luvhengo, Fhatuwani ; Vilakazi, Mlamuli ; Mamushiane, Lusani ; Lysko, Albert A Date: Sep 2023 This paper investigates four software tools with CPU power consumption estimation capabilities and identifies the most suitable tool for open fifth-generation (5G) and beyond research. The tools considered are Open Hardware Monitor (OHM), ... Read more
Testing performance for several use cases with an indoor OpenAirInterface USRP-Based base station

Author: Dludla, Angeline G ; Vilakazi, Mlamuli C ; Burger, Chris R ; Lysko, Albert A ; Ngcama, Lwando ; Mboweni, Lawrence ; Masonta, Moshe ; Kobo, Hlabishi I ; Mamushiane, Lusani Date: Nov 2022 This paper presents the early phases of the implementation of a Radio Access Network (RAN) based on OpenAirInterface (OAI) for a fifth-generation (5G) mobile network. Because the availability of full OAI 5G support was delayed, we initially ... Read more
Towards bridging the digital divide using innovative and community-based interventions

Author: Masonta, Moshe Date: Jun 2023 Access to high-speed broadband infrastructure and services plays a vital role towards achieving the United Nations’ Sustainable Development Goals (SDG). However, the International Telecommunication Union (ITU) revealed that only 63% of the ... Read more
