The test results didn't disclose many of the factors affecting WiFi range and performance, I'd like to know more about these. I think the key factors are:
* Nearest other WiFi unit. Interferance from nearby networks can hurt the signal-to-noise ratio.
* Proximity to walls and ground, as reflected signals may affect signal strength up or down.
* Polarization and coverage pattern, as lobes and nulls are inevitable.
The quantities I am really looking for are:
* Maximum usable range in free air and best conditions.
* Data rate in those conditions.
* Attinuation due to each intervening wall or ceiling on both 2.4 and 5 GHz bands.
With this information I might better evaluate which solution is best for a particular situation.
