Phase one of Sydney Airport's wireless network APEC-ready

200 antennas and 8km of fibre tested

Customised telecommunications solutions provider Kordia has completed the first phase of a complex in-building coverage (IBC) design to deliver wireless mobile access at the Sydney International Airport.

Phase one of the project, completed in time for the APEC Summit, covers all major public areas at the airport with remaining areas due for completion in October.

Vodafone Australia selected Kordia to design an in-building 2G and 3G WCDMA wireless network at the airport that could be shared by multiple telecommunications carriers.

Kordia managing director, Peter Robson, said the company presented a clever design using the existing airport backbone infrastructure combined with LGC Wireless' Unison active and passive technology.

He said this produced a cost-effective yet robust solution capable of combining technologies at 850Mhz, 900Mhz, 1800Mhz and 2100Mhz, satisfying the requirements of all carriers operating off the system.

To ensure the different technologies didn't interfere with one other, Robson said Kordia tested every component of the system for inter-modulation, which included 200 antennas and approximately 8km of fibre, co-axial and data cables.

"There was a high level of complexity to the project," he said.

" Agreement needed to be sought from all carriers on the required technologies and detailed design.

"Then, the IBC had to be built within a condensed two-month timeframe to meet Vodafone's requirements for the APEC Summit.

"Due to the enormous security complexity, build could only take place between 10pm and 6am each night, while ensuring zero impact on existing network services."
