While cellular carriers can reuse frequencies over large
areas, a two way radio system often is required to cover
a large area from one location.
In all cases, a tower, pole or other structure is required
to elevate the antennas to a height capable of covering
the required area.
Local governments often regulate the erection of towers.
In addition, labor regulations have increased the scrutiny
of those who climb towers.
Expert advice should be sought before planning or constructing
a communications structure.
