What is a wireless phone?
A wireless phone is a two-way radio. It has both a receiver and a transmitter. When a user makes a call, the voice sound is converted to radiofrequency energy and is transmitted to the nearest base station. Hence, a wireless phone exposes the user to small amounts of radiofrequency energy because of the short distance between the phone and the head. Wireless phones are also called mobile phones because they are hand-held and do not use wires and cables like conventional phones. (However, they are different from “cordless” phones that have a base unit connected to the telephone wiring system. These operate at very low power levels). Wireless phones are also called cellular or cell phones, for reasons that are explained in FAQ #21.
