Kordia has won the Best Project / Facility Rollout award for its recent digital radio project at the 2009 Annual Content & Technology Awards for Innovation. This was announced last night at the Society of Motion Pictures Technical Engineers (SMPTE) exhibition Gala Awards in Sydney.
Kordia played an instrumental role in the Digital Audio Broadcasting (DAB+) rollout in Australia’s five metropolitan capital cities – Sydney, Melbourne, Brisbane, Adelaide and Perth – during May and June.
“Kordia has leveraged its strong heritage in broadcast engineering to play a vital role in building one of the most spectrum efficient and sophisticated digital radio networks in the world,” said Kordia’s Managing Director: Peter Robson. “We are very honoured to be acknowledged for this major Australian broadcasting milestone.”
Kordia was commissioned as project manager for the rollout by Commercial Radio Australia (CRA) and worked closely with the transmission site supplier to CRA, TX Australia Pty Limited (TXA).
From project inception to implementation, Kordia completed the wide spectrum of complex engineering tasks within the tight timeframe. This included:
- project management for CRA
- pre and post-implementation coverage surveys for and with TXA resources
- design and supply of antenna mounts and associated steelwork
- installation of Rohde and Schwartz transmitters, RFS antenna systems and combiners
- electro-magnetic emission (EME) site surveys
All TXA broadcast transmission facilities across the five capital cities presented numerous logistical challenges. Moreover, the tight delivery timeline of six months meant that Kordia had to simultaneously deploy five specialist rigging teams; each comprising of up to eight riggers and technical specialists.
At least three tonnes of antennas and steelwork were installed at each TXA site. Most of these were mounted at heights of 180m to 200m metres on the TXA broadcast transmission towers, to provide maximum coverage.
The Band 3 antennas, which were used for both analogue and digital television services for Network 7, 9 and 10 and National ABC services, also had to be replaced.
Kordia installed innovative new antenna systems designed by RFS in close consultation with TXA to allow for the broadcast of both television (via horizontally polarised elements) and DAB+ services (via vertically polarised elements) from the same shared antenna panels.
This is the first of its kind in the region. It uses the highest power DAB+ transmitters in the world.
