This presentation presents a solution for creating and funding 5G testbeds for key university campuses to accelerate the development of smart cities in Africa. Cities become smarter as technology develops and people and things become increasingly connected. Thanks to the introduction of sensors and active data, cities will become more efficient, sustainable and habitable. 5G technology plays a central role in developing smart cities. (1) 5G contains cellular IoT standard which is suitable for Smart cities. (2) 5G contains the Ultra reliable low latency (URLLC) standard necessary for smart transportation design, necessary in smart cities. (3) 5G provides high bandwidth wireless connectivity, throughout smart cities for exchange of relevant data between government agencies and municipalities. The history of previous generations of mobile systems in Africa shows that when operators and equipment suppliers open their laboratories for young innovators to experiment with, mobile applications like MPESA, which provided financial access to several million unbanked subscribers, can flourish and impact the sustainable socio-economic development of society. But how do we create and finance these developmentally important 5G testbeds. This presentation presents a model with which 5G testbeds can be quickly started on central university campuses and instead of appearing as extra costs for universities, they are indeed means of earning for universities. By including 5G testbeds as part of the wider learning, innovation and remote work Tech Space concept, which also serves as an exceptionally good Talent and project platform for international and local companies, a new service concept with significant added value can be created on the market at the same time.
