Import Engineer Parameter
• Fill the field with the right name, it is same like mandatory item in Genex Probe, please don’t leave it blank. Then click OK
• Please wait while generating. Make sure all the field is correct

Import Engineer Parameter & Upload the Logfiles
Consulting | Training | Research
• Choose Analyze Group Manager and add logfile
Consulting | Training | Research
• Once finish, you can make a group for your logfiles with click analyze group manager and add choose your logfiles
Grouping the logfiles & Run the analysis
Consulting | Training | Research
• After that, you can view your logfiles group at the leftside, right click then run analysis

KPI Summary for cluster Drive Test
Consulting | Training | Research
Cluster Reporting & KPI (Setting Legend DL Throughput)
Choose DL grup -> click Legend -> search for Throughput Download -> Edit into standard
value
Throughput DL Legend
• Load all the logfiles and make a group depend on your method, for example we load the DL,UL,Ping,and SC test. After that we should set the download Legend (Throughput) for default .

Cluster Reporting & KPI (Setting Legend UL Throughput)
Choose UL group -> click Legend -> search for Throughput Upload -> Edit into standard
value
Throughput UL Legend
Consulting | Training | Research
Choose DL grup -> click Legend -> search for SINR -> Edit into standard value
SINR Legend
Choose DL grup -> click Legend -> search for RSRP -> Edit into standard value
RSRP Legend
Cluster Reporting & KPI (Setting SINR & RSRP)

- Speed is very useful to make sure your’e on the right track, in some case wes can got a lost signal while drive testing and its not recorder. But we can give justification by showing the speed map- Choose DL -

Cluster Reporting & KPI (Plotting Download (Throughput))
Choose DL grup -> search Throughput menu -> right click on PCC MAC Throughput -> Display On MapYou can add some route and legend with click the layer button and legend button
Consulting | Training | Research
-Histogram is very important thing while reporting, RF engineer can analyze the distribution of the Download value and make decision about the next step- Choose download -> search Throughput -> PCC MAC Throughput ->Display on Histogram

Cluster Reporting & KPI (Plotting Download (Histogram))
Consulting | Training | Research
-Display the statistics is needed to view the valid value for average,maximum,minimum range of the throughput.- Choose DL -> search MAC Throughput -> right click and display on sheet

Cluster Reporting & KPI (Plotting Download (add layer & Missing Route))
- Click the layer button to add some routes it will make you easier to locate where is the missing route and create justification at that area

Cluster Reporting & KPI (Plotting Download (set Legendand edit cell size))
A. Download
-Click legend button to view your throughput DT result,if necessary you can edit cell size to make it easier for analyzing logfiles. Choose the 1.20 size then click OK. You can see the difference cell result after that

Cluster Reporting & KPI (Plotting Download ( Plot & Synchronize PCI))
A. Download
- we should to synchonize the PCI to make it effective for reporting,you can define the site is cross feeder or not.- search for Serving and Neighboring Cell -> click serving cell -> right click and Display On Map- we can see from the picture above that the PCI is sycnhronized and we can define which site is not serving at that time

Cluster Reporting & KPI (Plotting Download ( RSRP))
A. Download
- RSRP plotting is needed to predict the low coverage at that area, you can see if there any blocking building oretc that causing the low coverage- Choose LTE -> Serving and Neighbouring cell -> Serving Cells -> RSRP
Consulting | Training | Research
Cluster Reporting & KPI (Plotting Download(Display RSRP Statistics and Histogram))
A. Download
- RSRP Statistics is needed to the average value, maximum or minimum value at that area
Consulting | Training | Research
Cluster Reporting & KPI (Plotting Download ( SINR))
A. Download
- SINR plotting is needed to predict the low quality at that area, you can see if there any intereferrence or etc thatcausing the low quality- LTE -> Radio Parameter -> PCC SINR
Consulting | Training | Research
Cluster Reporting & KPI (Plotting Download ( Hand Over))
A. Download
- Plotting Hand Over is using to define if there any hand over failure during the drive test, if any we can check theneighbour relationship and delete it if the location is more than one tier or the distance is too far- Choose DL -> LTE -> righ click on LTEintrafreqHOAttemp / success -> display on Map
Consulting | Training | Research
Cluster Reporting & KPI (Plotting Download (Scatter))
A. Download
- Scatter is using to compare the result of RSRP VS SINR, its needed for make a conclusion the distribution SINR and RSRP in yourroute- Choose DL -> right click on RSRP then custom display on chart -> choose Y axis, do the same step to SINR but choose the X axis

Cluster Reporting & KPI (Plotting Download (EARFC))
A. Download
- EARFCN is using to define the frequency while you Drive Test- choose DL -> serving cell -> Serving DL EARCN -> display on map
Consulting | Training | Research
Cluster Reporting & KPI (Plotting Upload (Map))
B. Upload
Choose UL grup -> search Throughput menu -> right click on PCC MAC Throughput UL-> Display On MapYou can add some route and legend with click the layer button and legend button

C. PING
-In Ping Method, we no need to plot the distribution, we just need to view the average value of that method- Choose LongCall test, -> search PS analys -> righ click on PING and display on sheet
Consulting | Training | Research
Cluster Reporting & KPI (Plotting Upload (Map))
D. Short Call
-In Shortcall test, we can see is there any dropped call, RRC SR, Connection SR, Etc- Choose SC test -> right click and view KPI result

SSV Reporting & KPI (Legend and site Information))
A. Global Method
It have different legend with cluster, because in cluster we have some interferrence, so that’s why operator give other value on it
RSRP Value
SINR Value

SSV Reporting & KPI
A. Global Method
Accessibilty is needed to guarantee our user can connect to the network as fast as possible and keep stable of course
Consulting | Training | Research
SSV Reporting & KPI
B. Idle to Active Test
Idle to Active: to measure how fast the response from UE to ENODEB
Consulting | Training | Research
SSV Reporting & KPI
C. Static test (PING test)
PING test: to make sure user can send and receive without interruption such as connection time out and latency is less than 30ms

SSV Reporting & KPI
D. Download (Download and Upload (near,middle,far )
Download and Upload: our user spread from near until far distance, that’s mean we should keep the network in the good performance
