What Telkom’s network looks like

Telkom CTO Alphonzo Samuels recently discussed Telkom’s network and wholesale services with investors, which included an overview of what Telkom’s network currently looks like.

Samuals said the quality and reach of their telecommunications infrastructure in South Africa has improved dramatically over the last decade.

The most notable areas of improvement, said Samuels, were:

  • The number of undersea cables that have landed on our shores
  • National and regional data backhaul networks being built by Telkom and others
  • Significant Metro and access fibre roll-out
  • Satellite coverage covering the country and beyond
  • Significant build out of mobile networks

Telkom formed part of many of these developments, and has by far the largest fixed line network in the country. Telkom’s mobile network is also steadily growing.

The following sections provides an overview of Telkom’s fixed line, mobile, and international networks.
