A landline network is a system of communication that uses physical wires to connect telephones. These networks transmit voice signals through copper or fiber-optic cables, allowing people to make calls over long distances. Landline phones are often considered reliable and provide clear sound quality. Landline networks are typically managed by telecommunications companies, which maintain the infrastructure needed for service. While mobile phones and internet-based communication have become more popular, landline networks still play a crucial role in providing stable connections, especially in areas with limited cellular coverage.
