1. Coverage Map Accuracy
2nd Nov 2016

2. Coverage Map Accuracy
Only calculate the value, no need analyze it fail or pass.

3. input
Cluster polygon
RND Output: Nominal plan RND_RSRP txt file, the tab file can’t accept.
DT result: DT RSRP txt file
Note: Coverage Map Accuracy compare RND to DT RSRP with in 8dB margin.

4. EXPORT FILE FROM NEMO Right click KPI-> Export file
Note : Minimum and Maximum value of nemo output is mismatch, choose the good value.

5. Create Point in mapinfo
Open txt file in mapinfo-> Create Points

6. Comparing DT and prediction on Mapinfo
Copy the following files:
“gridmakr.mbx” into “C:\Program Files\MapInfo\Professional\Tools”
“delta_calculation.thm” into “C:\Program Files \MapInfo\Professional\AddUser\ThmTmplt”
On Mapinfo – Tools – Tool Manager, check option “loaded” and autoload” for “Grid maker”

7. Comparing DT and prediction on Mapinfo
Create a grid that covers the entire DT route.
(see example)
Change the grid size as per requirement.
Select the location to save the grid file.
Table – Maintenance – table structure, select the newly created grid file.
Add field: add “prediction” (float type), “DT” (float type), “delta” (float type)
Add grid file into the current map window.

8. Example
Click this button
Grid size = 20m or 50m
file name and folder

9. Add new fields

10. Comparing DT and prediction on Mapinfo
Table – update column
(refer to example)
Update “DT” column before “prediction” column.
For “DT”, select “is within” option.

11. Comparing DT and prediction on Mapinfo
Query – query “DT” columns which has value < 0 (filter out squares without DT points)
File – Save Query – save the above query as xxxx.tab.
Open saved file above (xxxx.tab)

12. Comparing DT and prediction on Mapinfo
Table – update column
Select xxxx.tab (the tab is Query saved in last step, it’s very import to save time)
Update “Prediction” column to include the prediction values.
For prediction, select:
“intersect” option for .tab file exported from ATOLL directly.
“is within” option for .txt (or .csv) file exported from ATOLL.

13. Comparing DT and prediction on Mapinfo
Output:
For RSRP, (DT RSRP+8dBm) compare with RND RSRP.
Calculate the percent of “DT RSRP+8dB” >= RND RSRP.
