Fire shuts down cell towers in CA

> Of the 874 outages, 702 were blamed on loss of power to the cell tower site.
> A few, about 60, were down due to wind or fire damage to the sites themselves.
However, cell towers (and telephones in general) are important infrastructure. They should have been designed and maintained with the expectation that power failures will happen and failed safely over to battery/generator backup power.
The traditional POTS infrastructure was[1] designed to work without power for weeks. That involved no only battery backup, but also longer-lasting backup power (e.g. big tanks of diesel) for when the batteries ran out. Cell towers going down when the power was out for a few days is evidence that those towers were not designed to be critical infrastructure and shouldn't be used as a replacement for POTS or other actually-reliable communication methods.
[1] I have no idea if that reliability still exists, or if AT&T ruined that reliability in the name of "efficiency" and profit.

This is addressed in the article. It's unclear to me whether AT&T lines go down due to external power failure, but other providers don't use powered lines:
> Residents said even their once-reliable landlines and Internet, such as those operated by Frontier Communications, weren’t working. Comcast/Xfinity also was down.
> In the era of traditional phone service, Ma Bell’s lines were themselves energized and very reliable.
> But companies’ transition to Voice over Internet Protocol (VOIP) – with phone calls over the Internet – is dependent on outside electricity. VOIP calls fail when either the company’s facility or the resident’s home lacks backup power.
> Comcast customers lose service where the power is out at their home, because the services need energy to operate, according to Comcast’s Joan Hammel. Comcast service also stops if power is disrupted elsewhere in the network, she said. Comcast’s service, like all other companies who have transitioned to Voice over Internet Protocol (VOIP) telephony, fails when either the company’s facility or the resident’s home lacks backup power.
> “Like all PG&E customers, we are also affected by this power shutdown, said Vince Bitong of AT&T. “We are aware that service for some customers may be affected and we continue to move quickly to keep our customers, FirstNet subscribers and public safety agencies connected.”
We had similar issues when power went out in San Diego and took down most of the radio stations which are considered part of the emergency network. Until somebody actually lands in jail for not maintaining lawfully mandated emergency readiness, this kind of crap will continue.
> Federal regulators have rejected proposed changes by the Federal Communications Commission that would require all U.S. cell phone towers to have at least eight hours of backup power.

The current regulations only cover fixed line or fixed-line-like wireless services https://www.law.cornell.edu/cfr/text/47/12.5
A better solution is to require cell phone manufactures with over one million installed units in a given region to include an AM radio feature, even if it only enables when there is no cell service for a while. I know that some AM stations were taken out along with cell towers, but AM signals travel far and there is no doubt that many with an AM receiver in those areas could at least receive a broadcast from out of the area, especially if the local stations are not broadcasting interference. For extra credit, include auto Morse code detection (for even longer range broadcasts and also hearing impaired).
So I don’t know if it’s a matter of antennas, or a matter of “who listens to AM anymore?”
That doesn't clear things up.
The HN title isn't even taken from the page, and yet -- somehow -- it's still up in all its totally inaccurate glory.
While I'm grousing, the HN link is to a tweet that just links https://www.mercurynews.com/2019/10/28/why-you-cant-make-cel... ; unless we're really interested in the reply tweets, the Mercury News link might be a better target.
These systems include a power generator, servers, and a 2G GSM base station for ranges of about 10km.
They don't even require any Internet connection, since their only purpose is to allow emergency calls and SMS. Any cell phone can set up an emergency call then - no need for a special SIM card.
Vodafone has a humanitarian mission that sets up these systems all over the world. (They're using Huawei, though)

One interesting thing is they are also selling them to businesses to enable business continuity during power outages and their site discusses their use of their device in the current blackouts.

[Edit: or you ask some technician of your local operator to bring the system up :)]
But I agree with you.
So basically pay up or move out.
How exactly is the word supposed to get out in dangerous dry windy conditions if the power is out, the cells are out, and the hams move out?
There have been attempts to create apps that allow a combination of store and forward messaging and ad hoc network creation so that messages could be literally carried from where there is no mobile network coverage to places where there is or to be relayed through other devices.
Now I put on my tinfoil hat: the problem is that in densely populated areas this would eat into the revenue that the network operator gets from SMS so no operators have promoted the idea and of course it would be easy to make it somewhat resistant to eavesdropping so no state will promote it either.
Actually I don't know if those things are true but it seems like a plausible reason for the lack of peer to peer capabilities in modern smartphones.
See https://www.computerworld.com/article/2510683/peer-to-peer--...
Software products like Lifenet, Firechat, Bridgefy, and similar generally use wifi-direct or bluetooth to communicate and do support store and forward.
On the amateur radio side js8call does allow forwarding through 3rd parties and store and forward.
Granted the financial model for these kind of things is tricky, but they do seem to be getting more popular. But sure I don't expect any cell provider to help, and was pleasantly pleased when p2p/direct connections was added to android.
I was pretty interested in gotenna and wanted to add a DHT and internet gateway so that messages would be delivered globally if anyone in your mesh had an internet connection. They rejected my idea 8-(.
Smoke signals
"What does it mean?"
"There's a fire there."
"Oh, you can read smoke signals?"
"No."
To be fair, Cal fire and emergency agencies are well-equipped with two-way radios and repeaters. Ham radio operators don't actually do any direct activities with fire management, they might - a rare might - be in the right place at the right time to report a new fire, a structure or people under threat, but typically they don't. They do enhance the public's awareness of a fire's presence but I don't have knowledge of what else hams actually do for a fire.
