That of course depends on the output-power of the radios. The 5W versions
should provide enough output to cover most interference when all radios are
within close range. Indeed, if it gets very busy, like on an event, it will
get impossible, and you would indeed be better off with a wired system, or
something licensed where you are out of the PBR-spectrum (like VHF).
I have used the 150mW UHF-PBR's in Sydney, which is quite "radio-active"
and we never had any problems.
Oh, thinking of this, in some countries it is not allowed to use PBR on a
commercial-base, so better check this with the proper authorities.
