Landline telephony refers to traditional telephone systems that use physical wires to connect calls. These systems transmit voice signals over copper or fiber-optic cables, allowing people to communicate over long distances. Landline phones are typically installed in homes and businesses, providing a reliable means of communication. Despite the rise of mobile phones, landline telephony remains important in many areas. It often offers clearer call quality and is less susceptible to signal loss. Additionally, landlines can be essential during emergencies, as they usually work even when power outages occur, ensuring that people can reach emergency services.
