The Regulatory Agency for Electronic Communications and Postal Services (RATEL) carried out, in the period from September through December 2022, comparative quality parameter measurements and analysis in mobile communications networks (Mobile Network Benchmarking) involving all three mobile network operators in the Republic of Serbia, and performed comparative QoS testing in mobile networks, by measuring voice service and data transmission service quality parameters.

The Mobile Network Benchmarking was conducted in accordance with international standard ETSI TR 103 559 Annex A, enabling an objective assessment of the user’s experience and the quality of service of all mobile network operators.

The scoring methodology has been developed for the purpose of ranking mobile operators following the measurements, during which an assesment of users’ perception of the quality of mobile network services is made, namely transmission of voice, data and video content.

Benchmark measurements were carried out in 55 cities, along 16,000 km of roads and more than 1,400 km of rail corridors in the Republic of Serbia. During the campaign, more than 9,000 calls and 7,000 sessions were performed for each of the data transmission services in each operator’s network, in all available technologies (2G, 3G, 4G). The measurements included:

• measurement of quality parameters for voice service and data transmission services, including WhatsAPP message transmission,
• measurement of radio parameters for 2G/3G/4G technologies.

By implementing this methodology, it was found that Telekom Srbija had the best total score of 88.70 points, followed by A1 Srbija with 86.98 points and YETTEL with 84.06 points (out of possible 100), resulting in an average of 86.58 points.

This year’s results revealed an improvement in the quality of services provided by mobile operators to their users, compared with their previous year’s average score of 83.51 points.
