"Technology God" here as the sarcasm poster called me ... I'm not going to make it too easy on you since you could have simply Googled it and found out what I already know. I mentioned that a cell tower GENERATES a signal ... here's an excerpt from a site that will break it down for you

Besides the physical building, there are many components to make a complete cell tower:

Telephone lines (generally fiber)
