Re: New Sydney Light Rail to use TETRA
Posted: Wed Sep 07, 2016 7:08 am
One important bit of information is being overlooked
Sydney Light Rail is a private consortium/company - using 460mhz TETRA
Sydney Metro (AKA North West Rapid Transit and being extended to the City and the Bankstown line) is a private consortium/company - using 460Mhz TETRA
As private entities they can use whatever communication system they want or deem suitable.
TETRA seems to be popular for mass transport systems.
As for using the P25 network, the railways need exclusivity in the same way our emergency services demand .... Needs to be available when required ... Not when there is a talk path available. At the end day GSM-R was deemed by the major state railways as the best fit across all australian rail systems for voice and signalling - which is why the Federal Government reserved a block of 1800mhz spectrum back in 2013. On the basis that GSM-R is a Australian railway standard for the future the NSW Telco would have signed off on it as it was a 200 million dollar project.
