It completed the project of setting up an optical fiber cable network based on the advanced technology. On this basis it built the world-level information superhighway and established 3G mobile communication network system across the country.

A satellite communication system of our own style has been built thanks to the rapid growth of satellite communication capability based on the latest technology.

The communication optical fiber cable network was put on digital and automatic basis, radically updating the country's communication structure.

The Pyongyang Optical Fiber Cable Factory has strongly backed the project.

The nationwide optical fiber cable network system has been established amid the completion of communication infrastructure. The optical fiber communication network has been updated as a digital technology. The previous telephone switching system has been completely converted into a digital one and an automatic switching capacity of telephone has expanded nearly twenty times as against the past.

The communication machine plants have been updated and delicate and highly efficient communication equipment and materials have been mass-produced, positively promoting the modernization of the optical fiber communication.

The introduction of optical fibre cable to all parts of the country on the basis of up-to-date technology paved a wide avenue for developing the nation's tele-communication in the shortest possible time as desired.

This success helped cover the country with a network of high-speed communications of the world's advanced level.

The units in the field of communications have boosted the transmission band of communications between Pyongyang and provinces hundreds of times in a matter of half a year.

A large-capacity high speed communications channel of the world's high level has been built in a matter of one year, increasing the transmission capacity thousands of times.

The formation of high-speed communications network made it possible to ensure on a high level telephone, data and mobile communications, the dissemination of science and technology, distance education, on-line healthcare, video conference, etc.

A 3G mobile communications network has been formed throughout the country to facilitate telephone and mail services and render diverse services including transmission of image and multimedia.

A micro satellite communications network has been laid to provide a reliable guarantee for command communications for state economic management under any circumstances.

All the satellite communications and TV relay equipment have been digitalized in a brief span of time to digitalize the TV relay of international events by satellite.

High quality TV transmission equipment has been successfully installed to ensure international tele-communication and TV relay of international events by satellite on the highest level.

Thanks to the establishment of satellite communications system of Korean style, the nation's tele-communication network is capable of successfully ensuring any international conference and event.
