Just about half of Africa's population is within 25 kilometres of a fiber network for mobile telephone connections. In Nigeria this is much lower at 14%. Instead of having to lay costly fiber optic networks for high speed broadband connections Africa can benefit from new 5G network technologies that enable Africa to leapfrog to better high speed internet connections. The telecom company MTN has started testing 5G mobile internet in Nigeria with live demonstrations in Abuja and Calabar, and in other Nigerian cities during a 3 month trial period. Nigeria is one of the few African countries that is pushing 5G with rollout in 2020. 5G uses radio waves to transmit and receive data between an antenna and one's mobile phone. It operates at high radio wave frequencies which cannot travel as far as other frequencies, so a denser network of base stations or masts is needed. This makes it highly suitable for large urban areas. A report by GMSA shows that South Africa, Nigeria and Kenya and four other African countries will have 5G by 2025 and this will be about 3% of mobile data compared to 16% worldwide. Problems with use of 4G in Nigeria show the issues facing Africa. Cost of using 4G is high for the average user, so that only 4% of users of mobile internet in Nigeria are 4G even though Nigeria has an extensive 4G network. Instead 40% of Nigerian users use 3G networks. 5G faster internet could help Africa in areas such as health with telemedicine, and in remote education, say experts. They also say 5G rollout in Africa will benefit from drop in costs as the technology becomes widely used in Europe, China and America. ...
