Nathan,
No algorithm per say, however, when two waves that meet, at the same frequency,
they will have a net loss equivalent to the amplitude of the opposing wave --
This will yield in the weaker signal being drowned-out by the stronger signal
and the stronger signal being degraded by the strength of the weaker signal.
Moreover, as a radio signal loses power (amplitude) at a rate that is inversely
proportional to the distance squared, one can calculate signal strength at a
given distance from the source. This is a gross simplification, but essentially,
since both services are using the same frequencies they will both experience
degradation to their signal.
In an area the size of Pioneer square, there is no reason why both services
cannot coordinate the use of their frequencies. The fact that this band is
unregulated does not preclude courtesy and cooperation.

So what are the quantitative facts behind this claimed "degraded service"?
Is there some sort of known algorithm for determining reduction in
bandwidth/throughput based on the signal strength of overlapping base
stations at a certain point?
Thanks,
Nathan
