Some very basic help needed

[Moo]

Hello everyone,

I'm new to this forum, but come seeking your help. To make a long story short, I have a project for my degree that (amongst other things) involves implementing a variety of wireless devices (Bridges, APs and antennas). The problem is, my tutor has told me that I must find some sort of algorithm\equation to predict wireless range on these devices before I go out and map them, which seems rather silly to me.

I've looked everywhere I can, and can’t find an answer. Of course I am aware that it is not as simple as that, weather, walls etc can all interfere but if anyone has anything then I would be so very grateful. Even an equation to calculate the expected strength in open air would be fine as a starting point, as I have some info on a variety of wall-thicknesses can impede the signal

Thanks,

Martin
