Well, I doubt very much that the NBN would use this technology because it's still at CSIRO demonstrator stage. It would then have to go through something like the NICTA process to develop it into a ready-to-commercialise product that someone might want to invest it, and then in turn that would require the investor to gear up for mass production and have the supply chain in place -- wholesale supply, service, support, warranty repair of faulty units, technical manuals etc.

At this stage it's not even clear that any vendor would want to invest in the development of this technology, rather than some other technology.

Meanwhile NBN Co has already issued an RFP for a wireless solution. This will include recommendations on technology and equipment. Indeed, "Our wireless RFP we have just issued," NBN Co CEO Mike Quigley told Senate Estimates on 19 October, on page EC 92, and at the moment no-one would be in a position to offer that TV-channel-based system.


Also, the number of simultaneous user video streams per channel was... six. So, in each location with a TV repeater you'd be looking at maybe two dozen simultaneous users. Sounds like something only suitable for a village of 50 people out in the desert.
