Glo trailed with no records in several of the districts and third or fourth ranking in just a few.
AirtelTigo Chief Technical Officer, Amir Abdelazim said the company believes the fundamental way of human interaction is verbal communication, and although data was critical to its customers, they continue to invest heavily into improving voice quality because it is equally important.
"AirtelTigo is partnering with world class's class suppliers to ensure superior performance. Also through the consolidation of the Airtel and Tigo networks, the coverage will increase significantly as well as customer call and data quality experience," he added.
MTN said in a statement it believes its network is doing well because it has deployed high definition (HD) voice service, which is now live on its 3G network across the country.
The statement signed by MTN Ghana Chief Technical Officer, Mohammed Rufai said the company has earmarked US$144 million this year for network improvement alone.
Per what accounted for challenges telcos face in some districts, Airtel and Tigo informed the NCA that multiple fibre cuts were the main challenges which disrupted service and sometimes hindered them from meeting the stated KPIs.
Glo indicated that they require new sites to improve coverage especially in newly developing areas and will work to address this. They also submitted that some coverage issues were due to site outage and will focus on improving site availability.
MTN indicated that their three main challenges had to do with Site Acquisition, Fibre Cuts and Permitting challenges. In a few instances, they reported neighbourhood agitation with regards to the sites under constructions.
Vodafone simply said they will work closely with the Authority to rectify gaps identified.
Meanwhile, experts say while telcos continue to invest to improve network quality, it was also important to have compatible handheld devices that can communicate with technologies like the HD voice service in order for customers to derive the benefits.
