The first 19 will be "on air" by the end of August and is "in addition to the existing 959 sites in Johannesburg," the company said.
Some of the areas earmarked for additional sites in Johannesburg include Sandton, Fourways, Bryanston, Morningside, Soweto and Benoni amongst others.
Cell C will also be building an additional 70 indoor coverage sites in Johannesburg and Pretoria.
"Traffic on our network has doubled over the past year and we've been hard at work rolling out new sites and installing additional capacity to cater for this growth and restore quality," said Alan Knott-Craig, Cell C CEO.
"In particular, the network in Johannesburg and Pretoria has been taking strain. In addition to the new sites, we have also embarked on a project to optimise close to 900 existing sites in Johannesburg and Pretoria to improve coverage and minimise interference on the network in high-density areas. We expect these activities to be completed by the end of November 2013."
Knott-Craig added that Cell C will continue to roll out new sites, upgrade and optimise existing sites and add additional capacity across its network nationally.
