Import Engineer Parameter

• Click the LTE symbols then View the Engineer Parameter

• Upload your engineer parameter with the default format



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



• Choose Analyze Group Manager and add logfile



• 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



• After that, you can view your logfiles group at the leftside, right click then run

analysis



KPI Summary for cluster Drive Test

Cl t R ti & KPI (S tti L d DL



Cluster Reporting & KPI (Setting Legend DL

Throughput)

Choose DL grup -> click Legend -> search forThroughput 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 -> cl ick Legend -> search

for Throughput Upload -> Edit into standard

value

Throughput UL Legend



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 (Speed))




A. Download

Cluster Reporting & KPI (Plotting Download (Throughput))

Choose DL grup -> search Throughput menu -> right click on PCC MAC Throughput -> Display On Map

You can add some route and legend with click the layer button and legend button




-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

A. Download

Cluster Reporting & KPI (Plotting Download (Histogram))




-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 (Display Statisctics))

A. Download




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

A. Download




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 s ize 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 ( Plot & Synchronize PCI))

A. Download

- we should to synchonize the PCI to make it effective for reporting,youcan 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 or

etc that causing the low coverage

- Choose LTE -> Serving and Neighbouring cell -> Serving Cells -> RSRP




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




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 that

causing the low quality

- LTE -> Radio Parameter ->PCC SINR




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 the

neighbour relationship and delete it if the location is morethan one tier or the distance is too far

- Choose DL -> LTE -> righ click on LTEintrafreqHOAttemp / success ->display on Map




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 your

route

- Choose DL -> right click on RSRP then custom displayon 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 DriveTest

- chooseDL -> serving cell -> Serving DL EARCN -> display on map




Cluster Reporting & KPI (Plotting Upload (Map))

B. Upload

Choose UL grup -> search Throughput menu -> right click on PCC MAC Throughput UL-> Display On Map

You 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





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




SSV Reporting & KPI

B. Idle to Active Test

Idle to Active: to measure how fast the response from UE to ENODEB




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
