Total DT route: 550 KMs (Approximately) DT Date: 13th August to 31st August’2014 Time :From 9 am to 8 pm

The drive route was created to cover the dense population area , key commercial area, key residential area, Highways, Main Roads, Other roads and Streets in the composition mentioned below. The DT log shows that every area has covered in city area except vehicle accessible roads.

KPI Equipment and setupThe flowing equipment used to collect KPI data:

Mobile Station (MS), Model: Huawei U2800 Data Card (MS),Model: Huawei E372u GPS NMEA (WGS84), Model No: BU353 Power Source (Inverter). PC HP Probook 4340s Scanner Exflex

The flowing software used to collect and analyze KPI data: Genex probe. Genex assistant. MapInfo professional 10.5 Google earth. Microsoft office.

Voice Test AlgorithmWe have categorized voice call into two types’ short call and continuous call. Short call for 2 minute duration. This short call will be used to calculate call setup time CS accessibility, blocked call rate, dropped call rate etc. On the other hand Continuous call will be used to calculate SQI MOS. SQI MOS algorithm as per Airtel recommendation defined by the ITU..Scanner has used to measure coverage that means RXLEVEL as well as to measure Ec/Io value.

Voice Data Summary: For Voice testing in field level the major DT KPI is coverage area which can be represent by RxLevel is the collected RF energy after the correlation / descrambling process, usually given in dBm unit. RxLevel value generally fluctuates from -10 dBm to -120 dBm in theoritically. Here define the major four operator RxLevel plot. From this we can define the coverage distribution.

RxLevel Plot

2G Benchmark DT Report at Chittagong among Major Four Operator in Bangladesh 7

From the Rxlevel plot this is shown that some area of airtel found poor coverage. But overall is good.To minimize the poor coverage required some site as well as some optimization. Then Coverage plot will better than present situation. This Ploot is taken from outdoor DT.

RxLevel Graphical Presentation: For Details analysis of Coverage distribution among major four operator Pi chart is define here:

2G Benchmark DT Report at Chittagong among Major Four Operator in Bangladesh 8

If we consider the best value of RxLevel from (0 to -75 dBm) then from Pi Chart this is shown that

Airtel cover the near 92 percent area. Robi Cover the near 96 percent area B.Link Cover the near 91 percent area GP Cover the near 91 percent area

Overall Coverage Distribution:From total sample percentage distribution among four operator final results calculated according this equation by which coverage rate scoring will measured.

Coverage Rate Score(%) = (A%*10+B%*8+C%*6+D%*1)/10

Distribution plot according to this equation and percentage of various range of sample distribution:

Table: Coverage distribution scoring table

From Avobe all graphical and educational result we can say that

Robi presents the best coverage in Chittagong city for GSM technology and getting 1st position. Airtel presents 2nd position. Banglalink presents 3rd Position and

2G Benchmark DT Report at Chittagong among Major Four Operator in Bangladesh 9

Grameenphone presents 4th Position.

MOS DistributionLike as 2G, MOS is a major KPI of 2Gnetwork which is define the quality: To compare the MOS value of each operator defines the value by plotting. The MOS value presents from 0 to 5 ranges. Maximum the MOS value presents the good network quality. This MOS value counted from long call which is performed from MS1 to MS2.

Presentation of four Major Operator MOS value

From The MOS plotting result this is shown that maximum the best value which range from 3.5 to 5 presents the airtel. That means Airtel showing the best position according to MOS value. Then Grameenphone figure looking good.
