Appendix 1 – Regional KPIs Per Network ............................................................................ 20 2 May 2017 Introduction PURA is mandated by Section 13 of the PURA Act 2001 and Section 83 of the IC Act 2009 to monitor and measure the quality of service of licensed GSM operators and apply sanctions where the Licensees fail to meet set targets or to provide adequate information relating to Quality of Service. This report is produced and published by PURA in accordance with the Authority’s mandate, pursuant to Section 83 (d) of the IC Act and Section 10 of the Quality of Service Guidelines for Mobile Network Operators (MNOs) in The Gambia. The objective of the report is to benchmark, evaluate and publish quality Levels offered by Mobile Network Operators, based on identified Key Performance Indicators (KPIs). The Mobile Network Operators covered by the report include all four licensed MNOs. Currently, there are two types of mobile network services offered by the operators, 2G and 3G, as shown below: Operator Networks AFRICELL 2G, 3G COMIUM 2G GAMCEL 2G-A⃰, 2G-H*, 3G QCELL 2G, 3G Table 1 – Mobile Network Operators Gamcel 2G-A is the old Alcatel Network Gamcel 2G-H is the newer Huawei 2G Network. As new technologies are rolled out in the future, the reports will be adjusted accordingly. The assessments are conducted using state of the art, modern technology, to obtain data from the MNO’s systems directly. Human interference is minimal to zero. 3 May 2017 1.
