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.
Telkom’s access network
Telkom shared the following network diagram, illustrating what its access network topology looks like for copper, fibre, and LTE.
Telkom’s national fibre network
Samuels said that Telkom has more than 147,000 km of fibre, which is critical to support the current and future telecoms services in the country.
Telkom’s national mobile network
Telkom Mobile’s network consists of 2,428 3G sites, 1165 LTE sites, and 2426 Wi-Fi access points. This network covers 55% of South Africa’s population.
Telkom’s submarine cables
Telkom uses three cable systems to service its connectivity needs – SAT-3/SAFE, WACS, and Eassy – and uses 3 gateways – Yserfontein, Melkbosstrand, and Mtunzini.
The company also has terrestrial fibre which connects multiple SADC countries, and has 3 major earth stations to serve its satellite needs.
