Australian Researchers Push Near-Broadband IP Over VHF

Curmudgeon Rick writes "A research group at the Australian National University is getting symmetrical 250K bps at 20km, using "empty" 7MHz-wide broadcast TV allocations in the 45MHz band. Story here, project homepage here. Aim is to put some bandwidth out beyond the reach of the wires, where users are few and far between."

    Either the poster is dumber-than-a-brick or has less than zero understanding of RF engineering.

    "7Mhz is for Amateur radio frequencies."

    So? The slashdot-summary-article very very very very clearly states 7MHz-wide broadcast TV allocations in the 45MHz band .

    ie Frequency ~ 45MHz

    Bandwidth (ie width of the band of frequencies) +/- 3.5

    Where oh where does it say "frequency of 7MHz"?

    Anyway, this is talking about in Australia. What on earth or any other planet in the known universe does that have to do with FCC allcoation of frequency use in the US of A?
