Telecommunication operator Glo Mobile has been adjudged the best in Voice Call Audio Quality by the National Communications Authority (NCA) in a survey conducted for the Central Region from 3 – 12 May 2016.
The report revealed that “Glo was assessed to give good speech quality while MTN, Vodafone, Tigo and Aritel were assessed to give fair speech quality,”
According to NCA, the survey was conducted for all the communication operators except for Expresso due to technical challenges, adding that it has “notified operators of these findings and has directed all operators to improve their coverage in some localities by October 2016.”
The report explained that Voice Call Audio Quality is the perceptibility of the conversation during a call.
Voice Call Audio Quality is measured by a parameter called the Mean Opinion Score (MOS), which categorizes speech samples in ranges from 0 to 5 with 0 being poor and 5 rated as excellent.
After the analyses, Glo had an MOS score of 3.51 followed by MTN (3.49), Vodafone (3.44), Tigo (3.34) and Airtel (3.26).
The report pointed out that sanctions imposed on Vodafone for failure in Call Setup Time in the Central Region has been suspended pending resolution of outstanding issues while Airtel has been sanctioned for failing Call Congestion in the Central Region.
The NCA said in pursuing its stipulated 3G Cellular Mobile License obligations, it conducts quality of service tests nationwide to ensure that operators deliver quality service to consumers.
