Buildings, trees, hills, mountains, etc. all diminish a tower's transmission distance. Cell phones use regular line of sight radio signals. The more stuff that is in that line of sight between you and the tower, the less signal that gets through. You can't have cell sites running at 300+ watts and get better coverage. This is fine for a one-way device like a beeper because your beeper doesn't have to transmit back.
