"Not talking about loss off signal at all, rather the intereference. At half the maximum range of a 1 watt TX, a 32mw TX right next to the receiver will have the same signal strength... and interfere if on the same frequency. Further out and the 32ms watt TX next to the receiver will have a stronger signal."



I'm not talking about a loss of signal either. The energy density of a signal decreases as the signal is spread out over a larger distance from the source. The total radiated power remains the same.

32 mW TX right next to the receiver will have far more signal strength than a 1 watt TX at "half it's maximum range". They will not have the same strength. But yes, if they are operating on the same frequency it could result in interference. However, spread spectrum does have the ability to discriminate between two competing signals. but of course, that will only get you so far.
