Howdy all!
Here's a converstation starter for you:
What technologies do you either know about, or can conceive of developing so as to create data links between nodes without relying on internet transit?

Ham packet radio is obviously one potential option, but has the hamstring that it requires a special license so is unlikely to be as accessible by the general tinkerer community.

I've been looking at the potential to setup LoRa based (NOT LoRaWan) connections and think that the combination of low cost, long range, and licence free access has great potential. Speeds at realistic distances are fairly comporable to dialup.

To parallel amateur packet radio, CBers also do packet and I understand a

is NOT required. There's also the possibility of building a private 802.11 network not connected to the internet as well.

I'm currently a licensed radio operator so I could use packet.

Now you've done it. This started me into a rabbit hole of LoRa
vs LoRaWAN, TTN, etc..

This article was among the first:

Again, have to be a little careful here. While third party traffic rules aren't an issue (it's basically any TPT is permitted, unless explicitly prohibited), there can be an issue with content. This used to be an issue with Winlink as well, which made it controversial, since Winlink can transmit Internet originated traffic unattended. I can't remember how the ACMA changed the rules to allow this, without manual oversight.

I think FRS radios are used for this purpose in the US, being FM.

SMTP via RF in general is pretty simlar. Postfix, KA9Q, Sendmail, it's
all pretty similar, and is transport agnostic. Once the initial handshaking is done it pretty much sails through fine.

As I said, similar in concept, would like to see the details.

The biggest issues I see are the initial handshaking no matter which service you're looking to use as that's when all the data between each point is
shared such as MTU! The rule of thumb to prevent fragmenting frames is that
the lower MTU wins... however that's not always how it seems to go. Once all that is established, the rest falls into place fairly quickly. This is why
9600 is the preferred speed, but that's not to say 1200 doesn't fly. I've
even seen 300 baud on HF work to do SMTP mail with axMail :)

Cool. Yeah I've been around VoIP too long, where packets are tiny and overheads are big as a result, and you pretty much can't go below around 20kbps on the wire, because of the overheads, even if the payload is only 2400bps. :)

Around the time when I was operating a 2-line BBS in late 90's
to 2003, the phone companies already had LD plans that offered
nation-wide unlimited or limited calls for a fixed $20/mo or
so.

I had once such $20 plan for 500 minutes/mo or something like
that.

It worked well for moving mail to two LD hubs for a couple of
nets and for making crash calls to a few LD relatives that I
set up as points.

Although, the local bbs.scene grew because of it, and
people called local boards that could have gettogethers in
meatspace.

Yes.. the local aspect was a particular characeristic of
calling local boards (and the potential to meet the people you
were conversing with) back then.

Now you've done it. This started me into a rabbit hole of LoRa
vs LoRaWAN, TTN, etc..

Haha, yup. It is a rabbit hole, and most material you'll find is very much geared towards IOT implementations without much base level information made available for easy digestion.

When you say "NOT LoRaWan" are you referring to the entities
that have commercialized it?

No, LoRaWan refers to using a gateway to pass information from/to nodes and a network attached service. It's highly reliant on the presence of an IP network and is really meant to allow for remote sensors/switches to interact with a centralized server.

LoRa itself refers to the equipment and modulation and can be used directly for peer to peer links in a manner very analogous to the acoustic modems of the past, or TNCs in the Ham Packet sphere.

While I can see some potential use cases for LoRaWan implementations to be used in the hobby:

1) Providing peer to peer access to local services NOT just
available on the internet is more likely to attract the tinker/electronic hobbyist crowd. IMHO at least.

2) Relying on the internet is not a good way to seed services that are meant to be an alternative to aspects of it (once again, imho).

I know in the netherlands CB packet is not only legal but moreso used than amateur radio packet from what I've been told. 802.11 would be more feasible and a LOT faster. Just think of what big ISPs would do if they had to

Could LoRa be used to transmit mail packets between peers?

I think the range can be around 20klm - can it?

Yeah, there seem to be a few of us with similar curiosities and ambitions that way. That shows some promise for adoption and hobbyist attraction :)

Everything I've been reading hints at IOT devices, which I am assuming means low (status like) traffic.
Could LoRa be used to transmit mail packets between peers?

The really easily accessible LoRa information, and all the off the shelf modules are geared and directed towards IOT use. And you get far better range and connection reliability at lower link rates. Given that dialup speeds are typical, people tend to write it off for more than signalling use. I have found a couple projects that use peer to peer for exchanging data like sms messages and email. There's no reason it couldn't transfer mail packets, and that's one of the use cases I want to explore. I'd like to have a terminal node via LoRa as well, but even if it ends up having to be more of a mailserver/nntp server type link it could be a huge win I think.

I think the range can be around 20klm - can it?
I know nothing about this technology, so I'm curious...

That's dependent on several factors, but a low data rate link with good antennas with line of site in a rural environment should be able to hit those sorts of distances. From what I've read of experiences of people setting up longer links, 1-10 KM at dialup data rates is fairly achievable in an urban environment.

I'm still largely in the research stage, but have a box of tranceivers coming to start playing with. They've just been in customs processing limbo, which can take a while when dealing with the speed demons in Canadian customs... As soon as I have them in hand I'll be able to experiment more directly and report.

Yeah, I think the longer links would likely require some form of licenced band usage, but if there's a scenario where local areas can connect with cheap licence free options and then hub with someone handling the long distance hops it would still be fairly attractive - I mean it was when we were all on dialup.
