Fixed-line telecommunications commonly refer to the wired networks that support fixed broadband and telephone services. These forms of communication can be viewed as a connection to an end customer using a cable, through which the user can connect to the internet or make a phone call. Fixed data, or fixed broadband, involves the use of a variety of technologies for any high-speed data transmission to a residence or a business. Methods of transmission include cable modem internet, digital subscriber line (DSL) internet, fiber optic cable, and other fixed broadband technology connections. A landline telephone, or fixed phone line, is a telephone that transmits signals using metal wire or fiber optic cable, as opposed to wireless transmission as seen in mobile phones.
Revenue from fixed voice communication services is predicted to reach close to 142 billion U.S. dollars in 2022, a fall of over three percent compared to the previous year. Figures suggest there were around 884 million fixed telephone line subscriptions worldwide in 2021, with the market experiencing a gradual decline from the 2006 peak of over 1.26 billion. The advancement of mobile network technology, as well as older, networking infrastructure such as copper wiring becoming obsolete, has meant landline telephone use has declined in popularity. Instead, consumers are looking toward a newer digital technology known as voice over internet protocol (VoIP) which refers to phone calls that are made through the internet, rather than through a regular landline or a mobile network.
