    • Free-space optics backhaul: a strategic necessity for 5G and 6G rollout within Zimbabwe's emerging telecom environment 

      Kudzanai, C.; Simbarashe, M. (БНТУ, 2025)
      In 2024, Zimbabwe's mobile data traffic grew by 35 %, which put a lot of stress on the backhaul infrastructure [1]. Microwave links have limited capacity, and fibre is expensive in rough terrain. Free-Space Optics (FSO) is a solution that uses light beams to send data at speeds similar to fibre optics. This makes it possible to quickly deploy 5G and 6G in both rural and urban ...

    • Secure mesh networking chip designs for resilient iot and mobile systems 

      Gashirai, J.; Simbarashe, M. (БНТУ, 2025)
      This study introduces a hardware-software co-design for a secure, autonomous mesh networking infrastructure aimed at enhancing the resilience of IoT and mobile systems. Leveraging recent developments in LoRa mesh architectures, MANET routing, and hardware secure elements, we propose a cohesive SDR/ASIC-based node (the Compact AI Cube) that amalgamates multi-radio communications ...
