How many P4 can operate simultaneously in a location ?

[Jongsun Lee]

Hi,
I would like to know how many Phantom4 can operate simultaneously in same location. I used to connect 4~5 Phantom 3 at the same time. Someone said, more than 2000 P4 can connect and operate simultaneously. Is it true?

I assume since it's 2.4 there won't be interference
