Putting a wideband “high” power signal with a bandwidth and frequency matching an application (like gps / gsm / FM radio / wifi ) will block that application. Receiver blocking by an in-band interferer is a problem for 95% of every wireless link on the world. This is why we have authorities and regulations to guide spectral usage, that is why there is a duty rule.
I am afraid that the only way to deal with is to accept it, this is the ISM band, you have to share it with others, you don’t own it.
