Battle to Save the 9 cm Band
The 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.
