Rohde & Schwarz has been commissioned to supply terrestrial digital multimedia broadcasting (T-DMB) transmitter systems for the world’s first
T-DMB network in Korea. All of the various network operators involved in setting up the T-DMB transmitter networks in the country are being supplied with transmitter equipment by R&S. The system is used to transmit radio and TV programs as well as data to mobile receivers.
After a successful test phase with the company’s air-cooled transmitters, the network operator Korean Broadcasting System (KBS) ordered liquid-cooled T-DMB transmitter systems with an output power of 1.4 and 2.3 kW for regular operation. Rohde & Schwarz is also supplying further transmitters with air and liquid cooling for Seoul Broadcasting System (SBS), MBC and YTN.
The complete T-DMB transmitter systems are designed to meet high fail-safety requirements as all have passive standby, while a special redundant system of combiners has been developed to increase reliability. The equipment is currently being supplied with installation expected to be completed by the end of 2005.
