TDD Demonstrator and Testbed,
TD-SCDMA Trial Network in Beijing 2001
"In August 2000 we succeeded in transmitting high data rate IP traffic over TDD.   For the purpose of the demonstration, a video stream was used, signifying the world’s first video transmission over TDD [in a testbed].
Throughout 2001, we continued to demonstrate the capabilities of 3G wideband communications technology to mobile network operators around the world, including the USA, Dubai and Russia.   At an exhibition in Cannes, the testbed was used to demonstrate 3G communications between a ship and the mainland.   The testbed is now being adapted for an aircraft environment and it has already flown successfully, showing for the first time how 3G could be used to improve security and enhance air traffic management, airline operations and passenger services."
"Together with Siemens representatives in Munich, Milan and Beijing,   Roke Manor
Research is playing a significant role in helping to bring TD-SCDMA to the Chinese
market.   After many months of careful co-ordination and feedback, the team
successfully demonstrated the high range and high mobility of TD-SCDMA, achieving
video calls between
the trial network and a test vehicle at ranges of 16 km from the
basestation.   Shortly afterwards, Siemens CEO Dr Heinrich von Pierer praised
the team’s work when he was able to hold a video call with the Chairman of Datang
Mobile over TD-SCDMA."|
