Communications can, in fact, kill people. High-intensity electromagnetic emissions. Those cell towers in the middle of the city have to be very thougthfully planned and installed.
If "high-intensity electromagnetic emissions" from cell towers kill people, I doubt making them safe is just a matter of placement.
If you want to place some in the middle of a city, they will be close to a lot of people, and if their emissions kill people, it's probably not a good idea to place them near lots of people. But they have been placed pretty much everywhere. It appears that either you're overstating the dangers, or we're both about to die any second now.
