[AusNOG] Telstra customer routers contact

Just to quickly follow up on this, I was in error and had the 5725-5850 MHz band in my head as outdoor only. I could swear I had read that on the ACMA site but of course it’s not there.
The current version of the Radiocommunications (Low Interference Potential Devices) Class Licence 2015 at https://www.legislation.gov.au/Details/F2022C00281 <https://www.legislation.gov.au/Details/F2022C00281> says (there’s no change as far back as I dug too):
Class of transmitter
Permitted operating frequency band (MHz) (lower limit exclusive, upper limit inclusive)
Digital modulation transmitters
The radiated peak power spectral density in any 3 kHz must not exceed 25 mW per 3 kHz.
My apologies for the list noise and for apparently triggering some people by referencing these devices.
On a side, related, note apparently these routers sometime have an issue where they stop working on 2.4 GHz and as a result people crank up the power of the 5 GHz radio. I’d guess that that’s what has happened in this case since it’s only transmitting on a single chain which limits throughput but increases power output. Frustrating thing is that it’s set to 80 MHz too but in a NBN fixed wireless area where a single chain 20 MHz channel is faster than the Internet connection and going to both creating and receiving less interference…
Thanks again for the responses

This interferes with real outdoor links, and unless the router is mounted on a roof it would be in violation of ACMA rules. I’m hoping to get in touch with someone suitable in the team that manages these to get an update done to correctly limit these devices to the indoor spectrum only.
> I’ve included an example scan from a Mikrotik link of ours that had started playing up due to interference below. It shows a Telstra router broadcasting on 5805 MHz running with an 80 MHz bandwidth (eeeC) and on single chain instead of dual chain so that it can bump up it’s output power even higher. In this case it only leaves a single 20 MHz channel, or potentially 30 MHz with certain radios, at the top for anyone else.
