Incidentally, the original question came from the Soroush Resaneh

Well, now that you've given away 2 out of 3 answers, I can become part
of the problem instead of the solution. Might as well give up any
pretense of at being helpful. However, in the future, I suggest you
avoid answering student homework questions as they are expected to do
their own research and usually have much better learning resources at
their skools than are available on the internet.

3) Increased antenna gain causes distant source of interference to
now become a problem.
