Jon, I once attended a talk where the speaker proposes to do ray traicing...

And please keep in mind the GEOMETRIC "period" of minima and maxima in 

IIRC: Rule of thumb: half of the bearer frequencies wavelength. I.e. 
with GSM, round abouht 1 GHz, wavelength round about 30 centimetres.

I.e. 15 centimetres between two points of maximum receiving power.

It was exactly that moment, where I stopped giggling about the persons 
who I've seen "mobile phone callisthenics" by shifting around their 
phones 5 cm to the left or 10 cm to the right in order to increase their 
WWW browsers throughput.

And you want to simulate that, perhaps with ray tracing and perhaps a 
temporal resolution of say 1 ms and a geometric resolution of say 1 cm?

Sorry, I cannot take this seriously.
