Best Server (LTE Cell) raster data and polygons

[MEHMET HINC]

Hi All,

I'm an ex vertical mapper user but now fully switched to x64 platform and I have MapInfo Pro Raster. It seems that I can easily calculate for each polygon and how much % of signal strength this is good however I need to know from each specific LTE cell (Raster data) bringing a X pct with Y amount of signal strength.

It seems that it is easily to calculate total amount of signal from this raster data for each polygon but I need to have from each LTE cell when I have more than one serving cell (cell intersects polygon) to the polygon. This must be done by SDK because in interface I don't see any such an option and it returns only the value (Region Inspection) ?

So, I couldn't find anything about SDK ??? and this option is not available with current UI ? And basic functions in MapBasic does not give me what I want. 

What do you think ??? what are the options ? 

//PS it is not possible to have for each specific lte cell in each different raster file because in that case I would work with planning tool such as Atoll rather than mapinfo.

Cheers,

Mehmet

are you using a grid ? 30 meter?

Hi Glen,

50m in big/small cities and 100m on highways :)

can you send me a small example

seem easier to just do it in Atoll or Planet EV

Hi Glen,

Think like you have Atoll export for signal strength in vertical mapper grid format and you have the below situation where your grid is covered by 2 different cells (polygons) so I would like to know from which cell and how much % coverage and RSRP value . However like I said signal strength data is in grid format and when I use region inspection in MapInfo Pro Raster it will give me only the value evaluated from 2 cells (2 polygons) in total. So basically I need to know each polygons bring what to the grid...

Cheers,

Mehmet

Hi Mehmet,

I would do a proportionoverlap SQL query of the LTE dominance against your grid.

Ensure the grid has unique names against every 50x50m grid bin.

That will tell you for each LTE Cell, how much of the 50x50m grid is covered by that cell. 

So in your example below you would end up with the purple LTE cell returning about 80% (0.8) of the grid being covered and the green LTE cell would return around 15%, with 5% unaccounted for as not being covered.

Note that the proportionoverlap query against dominance plots like the LTE footprints will be very memory intensive. When exporting out of Atoll, I would try to average the LTE prediction to normalise the export to a smaller resolution. Look it up in the Atoll user manual how to do the Mapinfo exports in as clean and small a size as possible.

Making your grid bins larger will speed up things as well as you will have less bins to query against.

The quickest way to test the whole thing is to do an LTE export of a small geographical area and run the query on that to ensure you are getting the output expected.  Putting the wrong table first in the proportionoverlap query will end up returning the amount of overlap of the grid on the LTE cell rather than how much of the grid is covered by the LTE cell.

It should be in the form

Proportionoverlap(LTECell.OBJ, GRID.OBJ), LTECellREf,RSRP, GRID_REF, and any other columns from the original tables you want

Hi Ed,

Many thanks for your return but proportional overlap is not possible.

Coverage data (signal strength) data is raster not a vector. Previous one was just an example.
