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

 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. .

10. RECOMMENDATIONS 1.1. Contents from this technical report will be used and put in an appropriate format for publication. 1.2. As agreed with all Mobile Network Operators, they should ensure that faults are reported to the Authority, by email, in line with the fault reporting Guidelines. Planned maintenance or other offline periods should be reported prior to the event(s). 1.3. All new Cells should be reported to the Authority in writing, prior to putting them in service, as indicated in the QoS Guidelines. 1.4. Requests for QoS information or updates should be fulfilled as a matter of priority, on or before the stated deadline in the request. Data / information should be provided to the Authority promptly and consistently in prescribed standards. Deviation from the standards may be considered non- compliance.

November 2017

1.5. NO changes shall be made on the approved counters for the LPI Data without the express consent of the Authority. Such requests for approval must be in writing or by email. Non-compliance in this issue shall be considered serious a breach and will attract immediate regulatory action. 1.6. With effect from March 2017, the monthly comparative performance reports, along with other pertinent analyses and reports may be published on the PURA website and publicly accessible media as deemed necessary by the Authority.
