1. 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 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-B, 3G
QCELL 2G, 3G
Gamcel 2G-A is the old Alcatel Network
Gamcel 2G-B 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.

• AFRICELL 2G
During the month of November 2016, the AFRICELL 2G network was compliant in 7 out of 10 KPIs, as shown above. The network failed on CSSR, CSR and TCH Drop Rate.
The CSSR, CSR and CDR KPIs also indicated that during the period, 204, 289 and 368 BTSs respectively were non-conforming, i.e., performed below compliance levels.
At the end of November 2016, AFRICELL had a total of 466 2G BTSs deployed, out of which 12 BTSs went offline for some period during the month. These offline BTSs were not reported to PURA prior of after the downtime as required in the Authority’s Fault Reporting Guidelines.
November 2016
7
• COMIUM 2G
The COMIUM 2G network had 4 compliant KPIs out of 10, as shown in the table above. These were TCH Availability, SDCCH Availability, TCH Congestion and SDCCH Congestion rates.
Some of the non-compliant KPIs include CSSR, CSR, HO and Call Drop Rates.
CSSR, CSR and TCH Drop Rate KPIs had 204, 289 and 236 non-conforming cells respectively during the month.
During the month, out of a total of 269 total deployed BTSs, 49 went offline for a period, but were not reported to the Authority before or after the downtimes.
• GAMCEL – (ALCATEL) 2G-A
The GAMCEL (Alcatel) 2G-A network is their old Alcatel Network, which is being
phased out and is mostly operational in the provinces.
As seen from the 2G Table above, this network is compliant in 4 out of the 10 KPIs
shown. The non-compliant KPIs include TCH Availability and SDCCH Availability, at
57.33% and 74.23%.
At the end of November 2016, out of a total of 146 BTSs deployed on this network, 123 went offline for a period, but were not reported to the Authority before or after the downtimes.
• GAMCEL – (HUAWEI) 2G-B
The GAMCEL (Huawei) 2G network had 9 compliant KPIs out of 10, shown in the
table above. The only non-compliant KPI was the TCH Drop rate, at 4.19%.
In November 2016, out of a nationwide total of 326 deployed BTSs, 143 went offline
for a period, but were not reported to the Authority before or after the downtimes.
• GAMCEL – 2G-A AND 2G-B
The weighted average KPI values for GAMCEL’s Huawei 2G and Alcatel 2G may be
used in the future, to indicate a combined 2G Network. However, GAMCEL had
decommissioned some ALCATEL cells during the period and the application of
weighted average using the cells on both network would not yield accurate results for
analyses.
Indicative figures are however provided, as shown in the table above.
• QCELL – 2G
The QCELL 2G network rated a compliance level of 6 out of 10 KPIs for the month.
Some of the non-compliant KPIs include CSSR, CSR, HO Success and TCH Drop
Rates.
November 2016
8
TCH Availability, SDCCH Availability, and TCH Drop Rates were among the
compliant KPIs on the network during the period.
At the end of the reporting period, the network had a total of 592 BTSs deployed
countrywide, with 57 of them having gone offline for a period, but were not reported
to the Authority before or after the downtimes.

• AFRICELL 3G
The AFRICELL 3G network had a compliance level of 10 out of 13 KPIs in November
2016, as shown above.
The three non-compliant KPIs were PS Call Drop Rate, CS321InterRatHoSR and
PS321InterRatHoSR.
AFRICELL had 622 BTSs deployed in the 3G network, out of which 57 BTSs went
offline for a period, but were not reported to the Authority before or after the
downtimes.

• GAMCEL – 3G
GAMCEL’s 3G network showed 2 KPIs non-compliant as CS321InterRatHoSR and
PS321InterRatHoSR performed at 81.55% and 85.17% respectively.
With a total of 152 BTSs deployed, GAMTEL’s 3G network had only 1 BTS indicating
a downtime during the month. This was not reported to the Authority before or after
the event.
GAMCEL has better performance averages for many 3G KPIs, but it’s worth noting
that they only operate in the Greater Banjul Area (GBA) and in Kanilai.
• QCELL – 3G
QCELL’s 3G network successfully complied with 9 out of 13 KPIs. The noncompliant
KPIs, as shown in the table above, include CS RAB Setup Success Rate and CS
Voice Call Drop Rate
QCELL had 592 BTSs deployed nationwide on this network. None of the QCELL
BTSs had a downtime during the month!

9. NUMBER OF BASE STATIONS DEPLOYED
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 and/or base
stations to better serve the consumers, and increase geographic coverage.
At the end of November 2016, the number of base stations deployed by each operator
on each network is shown below.

11. RECOMMENDATIONS
1.1. Contents from this technical report may be used and put in an appropriate
format for publication.
1.2. As agreed with all MNOs, 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 base stations 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.
