Interferance c5c

i want to install c5c ptp but i have a 4g tower in front of me about 50 meter from my (A) point dose this tower will have interferance with my ptp link link about 7Km

As far as frequencies, it depends on your local regulations and if 4g services can be delivered over the 5 GHz spectrum. Probably not though.

Now if the 4g tower is blocking the link between the two towers or is even in the fresnel zone, then yes there could be issues.
