[AusNOG] Telstra customer routers contact

[mike at duxtel.com]

Hi Andrew,

 

There is actually no “outdoor only” spectrum in 5-6GHz bands – only “indoor only” (i.e. just because the specification requires some bands to be used ‘only indoors’ does not prohibit use of other bands in outdoor scenario (although EIRP limits still apply of course)

 

https://www.legislation.gov.au/Details/F2022C00281#:~:text=per%203%C2%A0kHz.-,60,5725%E2%80%935850,-4%20W

 

Since detected signal is just -82 dBm, it is probably not terribly close, so you may be able to improve the situation for your use by using an antenna with low/no side/backlobe characteristic (like the RF Elements horn series)

 

Cheers!

Mike.

Hi all,

 

I was wondering if there is anyone on the list that I can talk to about Telstra customer router wifi configs that are violating ACMA rules.

 

We see lots of Telstra supplied routers that select the *outdoor only* 5.8 GHz spectrum for their 5 GHz WiFi. 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.
