Interview: Roger Hislop on TV white-spaces spectrum

In this episode of the TechCentral podcast, Duncan McLeod talks to Internet Solutions senior research engineer Roger Hislop about television white-spaces (TVWS) spectrum and how the technology could be used to connect the unconnected.
In the podcast, Hislop explains what TVWS is, how it works and why it could be transformative for the telecommunications industry and for end users.
He explains why the technology could deliver Internet access to people at significantly lower cost than what is available from mobile operators today and why it will allow new entrants into the industry.
Hislop talks about the two TVWS trials that were conducted in South Africa - in the Western Cape and Limpopo - and the recent introduction by communications regulator Icasa of regulations to govern the introduction of commercial services, and why this is significant.
When can South Africans expect to see commercial services rolled out on the back of those regulations, who is likely to build TVWS networks and what sort of equipment will be needed to deploy infrastructure?
It's a great discussion - don't miss it!
