NCA Publishes Quarter Two Quality of Service Monitoring Results for Five Regions

NCA Tower, Accra, 7th July, 2018 – The National Communications Authority (NCA) has published the Mobile Network Quality of Service (QoS) Monitoring Results for five regions. These results cover 96 district capitals within five (5) regions namely Central, Brong-Ahafo, Volta, Upper East and Upper West Regions that were not covered in the earlier 2018 Quarter One (Q1) monitoring. In addition, the voice quality for 28 district capitals in the Ashanti Region that were not monitored in Q1 are also included; results for only two (2) Districts were made available after Q1 monitoring for the Ashanti Region.

Service attributes monitored included coverage obligations, voice quality and data quality as stated in the Mobile Network Operators (MNOs) licence conditions and with specific Key Performance Indicators (KPIs). All MNOs are 3G Licence Holders; and are required to provide service in all 216 District Capitals. MNOs are expected to meet and exceed the KPIs stated in their licences. The number of districts covered within the second quarter monitoring totaled 96. These excludes 28 districts in the Ashanti Region where the voice quality was monitored.

Results for Voice Quality (Voice Quality and Technical Parametres)

The voice quality measurement is based on Mean Opinion Score (MOS). MOS is a quality measure that is used to assess the human user’s opinion of call quality, testing of quality of voice transmission and measuring voice degradation. The standard for measuring MOS is an ITU accepted standard. The MOS is expressed as a single number in the range 1 to 5, where 1 is lowest perceived quality, and 5 is the highest perceived quality.

Per their 3G licence conditions, MNOs are required to meet a score of minimum MOS score 3.5 for more than 95% of calls. An example of the results is captured in Table 2 below:
