The document summarizes the results of a 2G benchmark test conducted by Huawei for Airtel in Chittagong, Bangladesh. It tested the key performance indicators of four major mobile operators - Airtel, GP, B.Link, and Robi. For voice tests, Robi showed the best coverage while Airtel ranked second. Airtel had the highest average MOS score of 3.48. For data tests, Airtel performed best in GPRS attach rate, FTP upload rate, and HTTP browsing while Robi was ranked first in PDP activation and FTP download rate.

Chittagong is a city in southeastern Bangladesh and the capital of an eponymous district and division. Built on the banks of the
Karnaphuli River, the city is home to Bangladesh's busiest seaport and has a population of over 5.7 million, making it the second
largest city in the country.
Today, Chittagong is one of the fastest growing cities in the world. A major commercial and industrial centre, the city also has a
globally competitive special economic zone. With the Port of Chittagong being expanded and developed, regional neighbors of
Bangladesh.
According to Telecommunication service and respect to business this city is very important for every operator .

Voice Test Algorithm
We 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
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.

8. 2G Benchmark DT Report at Chittagong among Major Four Operator in Bangladesh 8
RxLevel Graphical Presentation:
For Details analysis of Coverage distribution among major four operator Pi chart is define here:
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

9. 2G Benchmark DT Report at Chittagong among Major Four Operator in Bangladesh 9
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
 Grameenphone presents 4th
Position.
MOS Distribution

10. 2G Benchmark DT Report at Chittagong among Major Four Operator in Bangladesh 10
Like 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.
Average MOS value:

the best value. During DT short call value is collected by calling individual own operator number like as (Airtel-676, GP-444555,
Robi-959 & B.Link-4229).
This call setup time will be little increase/Decrease if we call one number to another number.
