The many mobile phones in a mobile communicate with this antenna on individual frequency channels, assigned from a common pool of frequencies. The goal of mobile Corporation should be to conserve radio bandwidth by frequency reuse. Very low power transmitters are employed Therefore the radio waves Employed in a cell tend not to travel significantly past the mobile, allowing the same frequencies to become reused in geographically divided cells. Each time a person carrying a cellphone crosses from one particular cell to a different, his telephone is instantly "handed off" seamlessly to the new antenna and assigned new frequencies.
