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-A,⃰ 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.
1.5. Data / information shall be provided to the Authority promptly and
consistently in prescribed standards. Deviation from the standards may be
considered non-compliance.
1.6. 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.
1.7. With effect from September 2017, the monthly comparative performance
reports, along with other pertinent analyses and reports may be published
on the PURA website as deemed necessary by the Authority.
