CSIRO looks to analog TV spectrum for 100Mbit wireless broadband

Australia has already rolled out its plans to bring high-speed broadband to 90% of the country's population via fiber optic lines, and it looks like the folks at CSIRO are now pitching in with some ideas of their own to bring speedy wireless broadband to that ever present "last mile," and anyone else looking for an extra wireless option. As with others, they're looking to take advantage of all the analog TV broadcast towers that'll become available once the digital switchover in the country is complete, and it seems that they also have a few tricks up their sleeves that could eventually deliver wireless speeds up to 100Mbit per second (though it'd apparently be between 12 and 50 megabits per second initially). To reach those speeds, the group is apparently experimenting with a combination of orthogonal frequency division multiplexing (or OFDM), used in basic wireless standards like 802.11g, and multiple input multiple output technology, or MIMO, which uses a range of antennas to transmit and receive multiple data streams. Of course, there's still quite a bit of work to be done before any of that moves beyond the lab, but CSIRO says that field trials could begin in 12 to 24 months, with a commercial rollout possible in the next three to five years.
