Predictive Wireless Surveys - Ekahau alternatives

Hi All,

My company is recently opening many new locations from small offices to huge warehouses. Wireless is our main connection type. I came on board recently and been asked to prepare BoMs for all new locations across the globe.

We have no budget to do site survey each time. I though predictive wireless site survey tool would help me a lot. Looking at Ekahau, but cost may be to high. Do you know other options on the market worth checking?

I need a tool mostly for predictive surveys. Will not have a chance to be on site in 95% of locations.

Thanks for any suggestions.
