Please also think about this from a long-term perspective - what are we going to need in 2030? what will be the world standard in 2030 for connectivity be.
If you look at the Internet today. More and more people are using services from the Internet instead of services from the local operator - e.g. Skype, Facebook, Google services, You Tube, Amazon, etc. The local telcos (Vodacom, MTN, Cell C and Telkom) are simply becoming bit pipes - and by 2030 connectivity to the Internet will be their sole source of revenue. By 2030, Internet connectivity should be a utility service (like access to water and electricity).
Don't underestimate the need for broadband is rural areas. Broadband Internet in the rural areas may make it cheaper for people in rural areas to use solar-powered 3D-printers to reproduce a spare part for a device than to drive to a urban area to get the part - if petrol is projected to cost much more by 2030. It may also be cheaper to use broadband internet for tele-medicine and holographic meetings than flying or driving (depending on the cost of fuel).
Where do you think the problems are now?
Lack of effective competition at a retail level - as the infrastructure owners have a monopoly over resources. Only a few networks have radio spectrum and don't allow access to non-spectrum holders. Telkom owns majority of the fixed line access and backhaul infrastructure.
How do we deal with these?
Spectrum is a national resource. Radio spectrum holders should allow smaller operators access to their network. Telkom's infrastructure and monopoly value was built during pre-90s and 90s when it had a monopoly and hence they should be subjected to the equivalent of infrastructure equality. They should also be required to provide services to rural areas at subsidised rates.
What is the most important intervention to be made to get cheaper, faster broadband to more people?
Reduce monopolies of infrastructure that was built on exclusive access to radio spectrum and licences in the past.
How do we deal with the problem of broadband services in rural areas?
Impose obligations on monopolies of infrastructure that was built on exclusive access to radio spectrum and licences in the past.
How would you like to see Telkom sorted out?
Split Telkom into multiple companies - Service Provider, Access Network, Backhaul Network, Wireless Network and International Gateway.
