New Measurement/Policy Brief: Mobile and Fixed Broadband in South Africa

Leave a comment

How do mobile and fixed broadband stack up in South Africa?

Unlike in more developed nations, where fixed-line broadband connectivity is the predominant form of broadband access, in South Africa, mobile broadband is predominant. Mobile broadband connectivity is also both cheaper and faster than fixed-line connectivity.   Unfortunately, our study using a BISmark testbed deployment in South Africa shows that wireless is inherently less stable than fixed broadband technologies such as XDSL and fibre and the implications of not having ubiquitous, reliable always-on high-speed connectivity for the economy and global competitiveness are serious.

For a detailed description about the methods applied for measuring broadband performance, download the policy paper draft that we co-authored with Research ICT Africa for comments on investigating broadband performance in South Africa 2013. (Comments welcome!)
