Can we send guided mobile (microwaves) signals in order to reduce environmental impact?

I am sustainable development student, often I read articles that mention, that mobile signals sent through mobile towers disturb environment (birds mostly). So, I want know, that can there be a cost-effective technology which can make these microwaves environment-friendly.And therefore have towers which can send and receive signals through a protected medium which would reduce this impact.
