Hi everyone! quick question.
I’m trying to use NetSpot Planning Mode to design a Wi-Fi setup. But now I’m stuck on the antenna part.
NetSpot lets me import antenna pattern files, but where am I actually supposed to get those files? Or do people just use the default antenna settings and move on?
I’m not doing a huge enterprise deployment, just trying to make the prediction more realistic. I don’t want to overcomplicate it, but I also don’t want to model everything wrong.
You usually get antenna pattern files from the vendor. Check the official product page, downloads section, technical documentation, or support portal for your access point or antenna model. Some vendors publish antenna patterns openly, especially for enterprise gear. Others hide them in support downloads, and some don’t publish them at all. If you can’t find the file, email support and ask for the antenna radiation pattern or antenna pattern file for your exact model. Don’t just grab a random file from a similar-looking antenna unless you’re okay with a rough estimate.
For a basic indoor design, I’d start without custom antenna files. Things like walls, layout scale, and where you put the AP matter way more than obsessing over antenna files anyway. But if you’re messing with heavy-duty enterprise gear or directional outdoor antennas, that’s when you definitely want to import the actual pattern.
NetSpot supports importing antenna patterns, but the file has to be in a format it can read. From what I’ve seen, supported pattern formats include things like .json, .ant, .ana, .msi, .adf, and .prn. So if you’re searching vendor sites, don’t just search “antenna file”. Try searches like:
“AP model antenna pattern file”
“AP model MSI antenna pattern”
“antenna radiation pattern download”
“vendor name antenna pattern”
For example, some vendors provide .msi antenna pattern files because those are commonly used in RF planning tools.
Check the AP vendor’s official site.
Check the antenna vendor’s site if the antenna is separate.
Look in datasheets, technical downloads, or RF planning downloads.
Contact vendor support if you can’t find it.
Use a generic/default antenna only if you understand it’s an approximation.
Also, make sure you’re using the file for the exact antenna/AP model. Same brand doesn’t mean same pattern. Even similar-looking antennas can have different gain, beamwidth, and vertical coverage.
