The Complete Handbook of Cordless Phones

Chapter 1: Understanding Cordless Phones

A cordless phone is a wireless telephone handset that communicates with a fixed base station, allowing you to move around a building or outdoor area while maintaining a voice call over a local radio link. The base station connects to a telephone line—either a landline (POTS), a PBX system, or an internet-based service—and relays calls between the handset and the public switched telephone network (or your internal phone system). The handset contains a rechargeable battery, a radio transceiver, a microphone and speaker, and a user interface; the base station contains another transceiver, a charger cradle, and the connection hardware to your actual phone line.

The key distinction is that cordless phones are not mobile phones. A mobile phone (cellular) communicates with distant cell towers through licensed public spectrum and works anywhere within tower range. A cordless phone communicates with a single base station over a much shorter distance—typically 50 to 500 feet in open space, depending on the frequency, power, and interference environment—and stops working entirely once you move beyond that range. This short-range, fixed-base-station model is why cordless phones are primarily a business and residential technology tied to a specific building or site, not a mobile technology.

This distinction matters because it determines when and why you would choose cordless phones. A business with a small or medium office, a restaurant, a warehouse, or a medical practice may use cordless phones to let staff move around while staying connected to the office phone line.
