3 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.. 2

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, 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. 6

8 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, 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, 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. 7

9 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.

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. 8

10 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! 6.

15 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, the number of base stations deployed by each operator on each network is shown below.
