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 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.

Compliance rate of 9/12 KPIs. The network failed on only the PS Call Drop Rate, CS321InterRatHoSR and

PS321InterRatHoSR, same as in the previous month. 733 Cells deployed at end of August 2017 No cells reported downtimes during the month.

GAMCEL – 3G

Compliance rate of 4/12 KPIs. The network failed on all but the CS Data CSSR, CS Voice CDR, PS Call Drop

Rate and Soft HO Success Rate. 135 Cells deployed at end of August 2017 No cells reported downtimes during the month.

It is worth noting that GAMCELL has the smallest deployment of 3G sites and they only

operate in the Greater Banjul Area (GBA) and in Kanilai.

In addition, GAMCELL had billing platform issues and their entire network was open

for free on-net calling and Internet access, free of charge since users could not

recharge their accounts.

The main desired impact of the QoS Monitoring System is the improvement of services by

MNOs, and this includes the addition of new and/or improved Cell Sites to better serve the

consumers, and increase geographic coverage.

At the end of August 2017, compared to December 31st 2016, the number of Cells

deployed by each operator on each network is shown below.
