Communications in Iran - Internet

Internet

In 1993 Iran became the second country in the Middle East to be connected to the Internet, and since then the government has made significant efforts to improve the nation's ICT infrastructure. Iran's national Internet connectivity infrastructure is based on two major networks: the public switched telephone network (PSTN) and the public data network. The PSTN provides a connection for end-users to Internet service providers (ISPs) over mostly digital lines and supports modem-based connections. The Data Communication Company of Iran (DCI), a subsidiary of TCI, operates the public data network. Iran's external Internet links use the basic Internet protocol of TCP/IP (transmission control protocol/Internet protocol) via satellite exclusively. For data lines, copper, fibre, satellite and microwave are the available media, and popular services are high-speed Internet via digital subscriber lines (DSL), high-bandwidth lease lines and satellite. About 33 Iranian cities are connected directly by the Trans-Asia-Europe cable network, or "silk road", connecting China to Europe.
