Workshop on the Public Application of DMB, Chongqing, China

Join us for a Workshop on the Public Application of DMB
Chongqing, China, 21 – 22 October, 2013
Co-sponsored by WorldDMB and Chongqing University of Posts and Telecommunication

The Microelectronics Laboratory of CQUPT has focused on the public application of DAB for several years and made progresses in various directions. Its work proves that DAB can have a wide range of applications on campus, in community and as an alarm system. 

Taking DAB on the CQUPT campus as an example, it is used for examinations, not only for listening tests but also to announce rules in voice/text before tests, to give instructions and messages in text during tests. Although FM can be used for listening (not as good quality as DAB), it cannot deliver digital messages, and other techniques cannot provide data to many terminals at exact same time. DAB is also used for releasing administrative information and broadcasting courses in audio and video. So DAB is ideal for educational use and it has actually become a facility of the university.

China suffers frequent disasters, such as earthquakes and cyclones. South-east Asian countries also suffer many cyclones and tsunamis. In these countries, an authoritative alarm network based on DAB can be built. All sorts of terminals such as screens, LEDs, loudspeakers and radios could be used to issue alarm and give instructions to evacuate, along with maps, warnings and other useful information. After a disaster, DAB could be used to deliver messages to manage evacuation, and to coordinate medical, fire brigade and rescue staff. In extreme situations, when all communications and transport are cut off, an isolated place could establish communication with the outside world, if it has a local DAB transmitter, even a low power one, in operation.

People now tend to rely on mobile phone and internet too much but ignore their limitations. In many situations broadcasting is the most reliable and easy solution. We need to explore what DAB can do as a compliment to mobile phone and internet.

For these applications, relevant techniques need to be developed. Fortunately, DAB standards are capable of supporting such applications. The workshop is a good opportunity to introduce and demonstrate their operation to delegates.

About CQUPT

Chongqing University of Posts and Telecommunications (CQUPT), founded in 1950, is located at Chongqing, the biggest city in Southwest China. There are over 20,000 students, including more than 3,000 postgraduates. It has a faculty of more than 1,600, and has 30 overseas prominent scholars as the visiting professors.

CQUPT is one of the origins of Chinese digital communication. In recent years, more than 1000 research papers have been published in SCI/ET over 600 scientific projects in either state or provincial and ministry level have been assumed, in which 80 projects were granted the “Scientific Research Achievement Awards”. CQUPT is the only university participating in the project of TD-SCDMA, the 3G mobile communication, in setting standards, researching and manufacturing the chips, developing the software and promoting the industrialization of the end products, and great success has been achieved. Being a core member, the university played an important role in the establishment of the first national "EPA Communication Standard for Industrial Measurement and Control System", which became the first in China to own independent intellectual property right and was recognized by IEC as international standard in the field of industrial automation.
