About the Project

In September 2017, SEE Telecom received the order for the radio transmission system covering the delivery of equipment allowing AM and FM retransmission in the 11km Liantang/Heung Yuen Wai link including the Cheung Shan tunnel in the North and the 4.8km Lung Shan tunnel in the South, the longest in Hong Kong. The equipment is equipped with necessary modulators allowing break-in message insertion inside the tunnel tubes for both tunnels.  Modulators and switches are foreseen to enable the following functionalities:

  • Simultaneous AM & FM “Bilingual” Voice break-in messages per tube, with different messages per tube and per tunnel, or e.g. VBI in tube 1 of Cheung Shan tunnel and Broadcast everywhere else.
  • VBI will be effective on FM and AM at the same time
