I'm looking for wireless heat mapping software. I'd love some that is free or cheap.

I'm only in the early days of starting my business and can't afford the Ekahau software, I've head it's USD4000.

I am happy to pay that money, if it was the main core of my business, but it isn't and I might have a job once a month for a wifi survey and can't justify spending that amount on a tool I'm going to use so little.

I have Windows 10 64 Bit
