telefonivõrgus

Telefonivõrgus refers to the telephone network in Estonian. It is the infrastructure that allows voice communication over distances using telephones. Historically, this network was primarily circuit-switched, meaning a dedicated physical connection was established between two phones for the duration of a call. This traditional network, often referred to as the Public Switched Telephone Network (PSTN), utilized copper wires for transmission.

In modern times, the telefonivõrgus has evolved significantly with the advent of digital technologies and the internet. Voice over Internet Protocol (VoIP) has become a prominent part of the network, allowing calls to be transmitted as data packets over the internet. This transition has enabled new features and services, such as video calls and unified communications. The infrastructure now comprises a mix of copper, fiber optic cables, and wireless technologies to support both traditional and newer forms of communication. Mobile networks, which are a crucial component of the overall telefonivõrgus, provide untethered access to voice and data services. The continued development of telecommunications aims to enhance speed, reliability, and accessibility for all users.
