They sure would interfere!  On a high building  or a hilltop at 100 watts
the range would be 50 miles or more.  Of course that's only from the fixed
location to the receiving telephone.  It is extremely stupid to use this
power on the fixed transmitter when the romote telephone only has a
couple of watts or usually much less.
