1. How does wireless phone service work? Similar to how a cordless phone works with its base in your kitchen or bedroom, wireless phones receive and transmit messages using low-power radio transmitters located in your community. Each transmitter serves a geographic area called a cell. Equipment within each cell relays your message to a mobile telephone switching office, which in turn sends the message to the local landline telephone system to complete your connection. As you travel from cell to cell, your calls are transferred to you without interruption. 2. What is the difference between analog and digital? Wireless calls can be transmitted using either digital or analog technology. Analog technology transmits your voice over airwaves to cellular antennas, much like a radio broadcast. Digital technology converts your voice into groups of electronic bits that are “reassembled” into your voice when they reach their destination.
