How Mobile Phone Towers Work

Cell phone towers emit signals in a "flower petal" pattern around the tower. This 360-degree radius around the tower is called a "cell" and this is what the term "cell" in cell phone means. (5) When your phone is in a "cell" you get good reception and when it isn"t in a "cell" you get poor reception. So, for a cell phone company to provide complete coverage cell phone towers and antenna towers must be positioned all across the country so that the "cells" overlap. You can begin to see what a huge infrastructure needs to be created to provide complete cell phone coverage. That"s why cell phone towers and antenna towers are so prevalent. Furthermore, that"s why these antennas are installed in so many places like rooftops, fire stations, schools and churches. This is what is necessary for complete coverage.
