Telkom’s mobile voice network comes out on top in Bloemfontein
MyBroadband Insights recently completed its Voice Network Testing Project and found that Telkom has Bloemfontein’s best mobile voice network.
The project assessed key performance indicators (KPIs) such as Call Setup Time, Call Setup Success Ratio, Dropped Call Ratio, and Speech Quality mean opinion score (MOS).
All four major South African mobile voice networks were tested — MTN, Vodacom, Cell C, and Telkom.
This project is the largest of its kind ever to take place in South Africa, comprising over 633 call hours and 10,000km of travel across South Africa’s major cities, secondary cities, smaller towns, and major roads.
To ensure accurate results, MyBroadband Insights partnered with Keysight distributor Coral-I and used the world-renowned Keysight Nemo testing platform.
Tests used an originating station and a terminating station, both using Android devices running custom firmware to measure network KPIs.
The terminating station was located in a building with a strong signal for each mobile voice network and a reliable backup power system to avoid potential power outage issues.
The data was collated using European Telecommunications Standards Institute (ETSI) specifications to determine the performance of each mobile voice network.
For Bloemfontein, the data revealed that Telkom has the leading mobile voice network, with an overall score of 93.9.
It also boasted a distinct advantage in Speech Quality MOS, with an impressive score of 4.38/5.
All four mobile voice networks performed excellently for Call Setup Success Ratios with a perfect 100%, while Vodacom, MTN, and Cell all had a 0% Dropped Call Ratio.
Vodacom boasted the best Call Setup Time at only 0.99 seconds.
