Fixed telephone definition

A fixed telephone, also known as a landline phone or a wired telephone, is a telephone that is connected to the Public Switched Telephone Network (PSTN) through a physical, wired connection. Unlike mobile phones, which rely on wireless communication technology to connect to the network, fixed telephones use copper wires or fiber-optic cables to transmit voice signals over a wired network.

Fixed telephones typically consist of a handset that is connected to a base unit via a cord, which in turn is connected to the phone line via a wall jack or other connection point. The phone line connects to a local exchange or central office, which routes calls to their destination.

Although fixed telephones have been largely replaced by mobile phones and other wireless devices, they are still widely used in many parts of the world, particularly in areas with poor mobile coverage or unreliable power supplies. They are also used in many businesses and homes as a backup communication system in case of emergencies or power outages.
