As reported earlier on jxeeno blog, nbn™ has begun testing the use of the 3.5GHz spectrum for Fixed Wireless in outer metropolitan areas.
The ACMA has updated the list of NBN Fixed Wireless towers where 3.5GHz transmitter and receivers have been installed:
|Tower Location||State||ACMA site ID|
|51 Jupp St PROSERPINE||Queensland||9017726|
|10 Morang Crescent MITCHELL PARK||Victoria||9015336|
Earlier, ZDNet reported that the antenna design for the 3.5GHz network will be similar to a “baseball mit”:
“that the antennas installed on top of the premises as part of the trial were designed similar to a “baseball mitt” in that although the 3.5GHz beam is relatively narrow, the capture of it on the antenna was wide to ensure that line to sight between the NBN Co tower and the premises’ antenna was maintained.”
However, the Department of Defense had raised concerns that utilising the 3.5GHz spectrum may interfere with radar capabilities.
While the actual assigned spectrum is 3.56GHz, the assignments were issued under nbn™’s existing 3.4GHz license which it acquired from the now defunct Austar satellite TV company. A full list of ACMA assignments can be found here.
