In every town and city in the world i think almost everywhere there is a tall building, they could be apartments, corporations, hospitals, etc whatever...

Why not use their tallness, (their roofs as) as signal trasmitter whether is Cell Phones or Radio Transmission or some other transmission, like towers....I dont know if they thought about it already....Just trying to help...

They like to go to mountains but how many, MOUNTAINS ARE THERE...Like for in the city...

And you just rent the roof from a Tall building...Dont you hear all the time that phones are losing signals or radio cant be heard that good.....

or to create: Internet Networks or small networks...

I was just trying to find a use for the roof of tall buildings...
