I have bought a pump. Its job is to spray the house all over with water when a #bushfire comes. There's only so much water, so it needs to be timed right, otherwise the house will dry out before the heat arrives.
So, attached to the pump is a controller made by the thoughtful and nice Graham and Matt at Small Farm Services. (https://smallfarmservices.net.au).
I send it a 'start' over SMS and it starts. Later it sends me status messages. Marvelous.
The trouble, of course, is that #mobile #networks get turned off and/or fail during bushfires.
#Optus, #Telstra, any chance you could give me an indication of failure modes during fires? No, I didn't really think you would. <rolls eyes>. Did you know that #Optus funded a CRC into bushfires at ANU? It did/does really good stuff. (https://brcoe.org). Optus has issued press releases like this: https://www.optus.com.au/about/media-centre/media-releases/2023/11/optus-invests-to-protect-bushfire-prone-communities.
I cannot find out what MY base station's remaining vulnerabilities are, nor understand it's dependancies. Can *that one* last 20 hours without power? Can it's upstream links? Can I send an SMS over it if it is disconnected from Optus' authentication, authorisation and billing systems? What about Telstra? Coverage of both is good and I can see both towers - an advantage of living on a hill.
Without solid answers, I am looking to add some backup communications channel. I have an existing #LoRaWAN setup, and am wondering about firming it up and extending it out to very long range. The safe place I will be during the fire is about 10km away. Maybe that is the best independent path? But, maybe I should use some UHF data medium instead of LoRa? Something plainer, more commonly understood and dull?
Questions:
Anyone have resilience information for 4G SMS networks?
Should I buy a #Telstra or Optus #SIM?
Backup medium? What is the most solid thing for, say 10km?
What does The Department of #Radio Mastodon think please?
