The Genex Assistant is a post-data collection analysis tool which are part of the Genex
series that works with many systems, such as GSM,W CDMA,W iMAX and LTE.
Assistant enables network planning engineers and network optimization engineers to
learn about network performance clearly, locate network problems quickly, improve
work efficiency, and reduce the operational expenditure (OPEX) of operators.
The Genex Assistant processes data automatically, analyze and quickly collects the
statistics of data, and generates reports according to the preset analysis requirements.

9. For the Coverage Probability(85% RSRP>-110dBm&SINR>-3dB)
Click on IE Tab.
Go to “Serving and Neighboring Cells” and expand it.
Right click the selected parameters in red box and display on map to show the
coverage plot / display on caky to get the KPI values for coverage satisfying
the conditions committed to the customer.
10. For Hand off: The values should be taken from
Delay - > HO - > LTE Inter Frequency HO Time Delay right click on it and
Display on sheet and export it to excel.
Suggestion:
In Excel use Left(datetime of LTE Intra Frequency HO Time,20) to get the
minutes information, and then use countif to calculate the times of LTE Intra
Frequency HO Time in each minute.

11. For the Burst Error Rate(BER) and Drop Session Rate(DSR)
We ne e d to do filte r : SINR: 3dB,RSRP: -95dBm
Click on “Configura tion > P roje ct S e tting > Filte r > Add.
The n input S e rving RS RP : > -95dBm a nd Ave ra ge S INR > 3dB, the n click “OK”.
Go ba ck to Analysis Group, right click it the n Run Analysis a ga in.

12. After Run Analysis in Filter mode, now you can get the BER values :
Go to IE > LTE > BLER > DL > Code 0 Residual BLER(%), Dis pla y on s he e t e xport it to e xce l a nd ge t the a ve ra ge va lue .

13. After Run Analysis in Filter mode, now you can get the Drop Session Rate(DSR%) values :
Go to View > KPI Result > Retainability > Session Drop Rate(%).

KPI Stationary Test
Cell edge coverage probability
For the cell edge coverage probability, select 20 edge points (SINR is higher than 0dB but lower than 5dB &
RSRP is lower than -95dB) to perform ftp download, each point last 1 min. Record the detail coordinates and test results.The
RSRP and SINR must be check from Probe, you can use test plan to download and take a Snapshots.
Ce ll e d g e a va ila bility = s uc c e s s ful p o ints /2 0 *1 0 0 %

Maximum Round trip Delay and Jitter
For the Maximum round trip latency, select 1 edge point to perform the ping test. This point must be meet the
condition of -100<RSRP<-90.The ping packet size is 32KB and the ping repeat time is 100. Record the average ping delay.
This test should be implemented for 20% of sectors per cluster.
A c e p ta ble range: the average value is less than 60 ms
c
Ta rg e t range: the average value is less than 50 ms
Calculate the maximum jitter based on above ping result. 5 biggest jitter values can be canceled. This test
should be implemented for 20% of sectors per cluster.

Sector Level – Average Downstream/Upstream Throughput
To the average downstream/upstream throughput (sector level), Use 2 Terminal to perform the ftp download/ upload for
1 min at the same time.
One point (good point) must be get 64 QAM (higher than MCS16 in probe, and RANK2 SINR1 should be between 13 and
18.
The other point (bad point) You have to look at your MCS here. MCS must be 16 QAM (i.e. MCS10 to MCS16)

Please note that your combined DL and UL Throughputs should met the following criteria:
DL:UL (2:2 Configuration)
At good point should be able to get higher than 45 Mbps when downloading alone, and higher than 20 Mbps when
downloading in parallel with User-1.
At bad point should be able to get higher than 20 Mbps when downloading alone, and higher than 15 Mbps when
downloading in parallel with User-2
The combined DL Throughput (User1+User2) should be between 35Mbps and 40Mbps
The combined UL Throughput (user1+user2) should be between 17Mbps and 20Mbps
DL:UL (3:1 Configuration)
The combined DL Throughput (user1+user2) should be between 40Mbps and 45Mbps
The combined UL Throughput (user1+user2) should be between 7Mbps and 8Mbps


26 26

Terminal Level – Average Downstream/Upstream Throughput
For average Downstream/Upstream Throughput (Terminal Level).
Select 3 points of one sector (RSRP=-105~-95 / -95~-80/ >-80 、 SINR=0~10/15~25/25~35) to perform the ftp download/
upload for 1 min. Record the average throughput of the 3 points. This test should be implemented for 20% of sectors per
cluster.
Please pay more attention to 3 points:

RSRP=-105~-95, SINR=0~10, keep the DL throughput between 5M to 15M

RSRP=-95~-80, SINR=15~25, keep the DL throughput between 25M to 35M

RSRP>-80, SINR=25~35, keep the DL throughput between 45M to 55M

DL Average Throughput:
Acceptable range: the result should higher than 4 Mbps ;
Target range: the result should higher than 4 Mbps;
UL Average Throughput:
Acceptable range: the result should higher than 1 Mbps ;
Target range: the result should higher than 1 Mbps ;
