MTN has invested significantly in its network in the past year, adding new towers and expanding 3G and 4G coverage.
MTN Group chief technology and information officer, and chief technology officer for MTN South Africa, Babak Fouladi said between September 2015 and 2016, MTN rolled out around 1,300 new physical sites – across urban and rural areas.
Over the past 18 months, MTN rolled out 4,500 additional LTE sites in key cities and doubled LTE throughput.
Fouladi said they were able to increase throughput through more efficient use of the frequency spectrum their network runs on.
MTN now uses a full 10MHz in its allocation in the 1,800MHz band.
MTN has also rolled out carrier aggregation technology in certain areas, bringing an additional 15MHz of spectrum to its 4G network.
It has also invested in fibre to increase transmission and transport layer capacity, said Fouladi. Fibre has been rolled out to around 900 additional sites.
In addition to expanding its LTE and 4G network, MTN has also improved its 3G coverage and quality.
Approximately 2,400 new 3G sites were rolled out between September 2015 and 2016.
MTN has also refarmed 5MHz of spectrum in its 900MHz band, he said.
Fouladi said this has been layered on top of the 3G network running in its 2,100MHz band for greater coverage.
