    Battle to save the 9cm band

    The Wireless Institute of Australia (WIA) has lodged a strong submission to the Department of Communications to save loss of access to two segments of our 9 cm band – a 25 MHz block at 3400-3425 MHz and a 50 MHz block at 3492.5-3542.5 MHz.

    In August, the Minister for Communications, the Hon Malcolm Turnbull MP, issued the ACMA a draft Direction to enable licensing of these two spectrum blocks to the National Broadband Network for fixed wireless services in metro fringe and hard to service areas of the major mainland cities.

    The Department of Communications called for comment, with a closing date of 22 September 2014.

    The block at 3400-3425 MHz overlays the narrowband, weak-signal and satellite segment in the bandplan at 3400-3410 MHz, which also includes beacons. Many countries throughout the three ITU regions have amateur allocations covering this segment. The WIA has argued for retention of 3400-3410 MHz to maintain harmonisation with amateur allocations across the world.

    In summary, the Institute’s submission put the case as follows:

    1. The WIA seeks preservation of Amateur Service use of 3400-3410 MHz Australia-wide, consistent with international allocations and CEPT footnote EU17 in Region 1, and suggests that a 25 MHz block for the NBN could be found elsewhere in the 3400–3600 MHz band.

    2. In addition, the WIA seeks preservation of Amateur Service use of 3492.5–3542.5 MHz (and the repositioned 25 MHz NBN block) outside those geographic areas where NBN fixed wireless services are deployed, such that any likely interference to the NBN service is obviated and subject to the existing provisions of secondary services.

    For ten years I have been warning about expected loss(es) of the 9cm band. This is the first of many such losses. US will be one of the next IMO.

    There are many hams in telecom who defend ham radio, but we neither get the backup we need. nor the interst from other hams. Instead we get vilified as shills or traitors.. Quite the opposite.And this band is almost unused...even now..

    There are probably a very small amount of people who have interest in using the band or even have equipment to use the band. I would guess experimenters and EME'ers make up most of the population of hams that use it?

    Can honestly say I have never used or even heard of this band & I'm sure I'm in the majority.Don't have room for antennas for every band nor do I need every band.Honestly I have more band space to use now with just HF,6 meters,2 meters,& 440 mhz than I will ever use.Not but so many hours in a day & other things to do other than Ham Radio.

    Actually not the first - The UK 3.4GHz / 9cm band is being reduced from 3400-3475 down to 3400-3410 MHz

    I fully expect this band to be reassigned to broadband networks that better serve the public at-large -- in Austrailia and elsewhere.

    The voracious demand for "broadband" spectrum is known... especially below 1 GHz. There's similar pressure into the lower microwave bands as well.

    Technology moves on... requirements change. It is what it is.

    It is only a matter of time before amateur radio will lose the majority of its UHF and microwave bands.

    The reason is simply that this is spectrum "prime estate" for mobile telephony and broadband.

    Spectrum in these regions may be auctioned for billions, as soon as the current primary users, radiolocation a.k.a. radar move on
    upwards in frequency.

    Support from the Administrations and industry cannot any longer be counted on, as
    amateur radio nowadays has got a well-founded image
    as appliance operators of dubious competence.

    I wish that I could join you at the upcoming RCA event. Enjoy yourself.

    If this was to happen in the US, there would be thousands of ham's screaming "Don't take our bands away!!!!!!" Out of those thousands, probably 5 people actually use the band.

    I say, "go for it." Ham radio is a hobby, and it's not important in the grand scheme of things. Our world has become wireless and broadband dependent, and with more and more devices needing wireless network connectivity, the bandwidth has to come from somewhere. I could see the ham community raising hell if 160M-70cm were in danger, but the 900 MHz and above ham bands are just not that widely utilized in most of the US. Sure, a few major metro areas have an active 900/1200 MHz amateur community due to overcrowding of 2M/222/440 MHz (and things like crossband point-to-point links), but in the majority of the country the ham bands above 70cm are quite dead.

    It doesn't help the fact that there are virtually no off-the-shelf radios that do 900 MHz and above. A few exist for 1200 Mhz, but 900 MHz or bands above 1200 MHz require the kind of technical skill that most hams today do not have. 900 MHz is doable with some modified Motorola/LMR gear, but beyond that, you better get out your soldering iron. The hobby has changed since the 1950's. Long gone are the days of homebrew rigs being the norm, we've shifted to appliance operators as the norm and homebrew equipment being a niche hobby.

    Amateur Radio is a hobby that I hold dear to my heart. However, as a Network Admin by trade and tech geek at heart who loves the latest and greatest wireless gadget, I say "Please take our GHz bands." We don't use them, and we could all benefit from having more wireless bandwidth. But leave HF, 6 Meters, 2 Meters, and 70cm alone. (222 Mhz, what's that?? LOL) Those bands are ours and we use them.

    I 100% agree. I too am a Network Admin in the CLEC/ISP world. It comes down to use it or loose it. If hams are not going to use it then turn it over to something useful. That being said that Use it or loose it should be something that is applied to ALL spectrum users, not just hams. If commercial companies are buying up spectrum just to squat on it then they should have it taken away and put that spectrum to good use.
