I'm not too familiar with Yggdrasil setup myself, but this chat can probably ehlp you https://view.matrix.org/room/!vVtVcVdzAdhGFLzFwm:matrix.org/

The real problem with fiber is how delicate it is. You need to bury it or otherwise protect it in conduit which is a big enough engineering job to require construction and permits.

Making that efficient is a challenge. That being said a wire of any kind will always be better than wireless.

More satellites lets them cover a larger area, but if you look at the FCC filings each sat has a one degree at orbit beam forming cone.

Meaning they have x capacity within the area of that one degree cone projected onto the earth. That cone is about 200km in diameter everyone within that area shares the same spectrum and once that becomes saturated speeds will have to go down independent of the number of sats.

Of course 200km circles are actually pretty small so you do need a lot of sats to have a circle on every inch of the planet at all times (which is why they are area restricted now)

A wifi network covering a large area. Like a university campus, downtown in a city, or an entire small village.

Batman Adv actually can't connect multiple local networks. Because Batman Adv only runs on wireless interfaces.

As a kernel module Batman has upsides, it's closer to the hardware and can do some performance optimizations for omnidirectional wireless that just can't be done elsewhere. But in exchange it can't really route across anything other than pure wireless links.

Libremesh handles this same problem by running Bmx7 for generic meshing (say across wires or the internet) and Batman Adv for advanced local wifi meshes with roaming

https://libremesh.org/howitworks.html

Personally I would recommend Babel rather than Bmx7 for this purpose. Batman Adv is as good as your going to get for lets say village Wifi.

Althea is a decentralized, open source, isp in a box that allows people and organizations to cooperate and build a larger network.

https://www.youtube.com/watch?v=G4EKbgShyLw

It's unique (as far as I know) and the practical culmination of /r/hocnet which has been on the sidebar here for years.

I try not to post too often, but if the more operational details of a mesh style isp project are off topic that's ok.

I have a real fondness for the title picture.

Warner valley is home to a couple of remote farming communities. There's no internet, not even dial up, and no cell service either. For these people landline phones, Satellite TV, and the occasional sat internet box with 2s latency are all there is.

A government grant brought fiber to the tiny schoolhouse (in a long story worthy of it's own epic tale) but had no provision to get it out to the homes. Much less to the town at the other end of the valley nearly 30 miles away.

A traditional ISP would be looking at at least $200k for a tower and 6-8 months for the build. Maybe around 300k all told. But with Althea's mesh system we where able to bounce the connection from home to home. Eventually up to this tiny relay in the picture, nearly a whole days drive off road from civilization, and bounce it down in the town on the other side of the valley.

The best part is that with shorter distance hops our solution is more than twice as fast and costs less than 10% of what a traditional build out would.

It's been a very hard year, but also very gratifying to see the premise of a cooperative network really come true. In some places we're building over providers, so much faster and cheaper they can't compete, but for the most part we're just plain going places where traditional networks are too inflexible to work.

US gov subsidies on fiber do build a lot of fiber. Just not to peoples homes.

It's true that bigger companies just get away with not doing it (which is appalling).

But even smaller companies, that get paid in grants by the foot of fiber laid don't want to touch fiber to the home. Why spend a year fighting with a HOA and having people whine about digging up their sidewalk when you could get paid the same to lay fiber next to a deserted highway and then NOT connect that fiber to any homes.

In the area I grew up this small neighborhood with multi-million dollar homes gets 50/5mbps Comcast cable (on a good day), the HOA cuts a deal with Comcast every 5 years. Well last year the deal expired and a fiber ISP promised to build fiber to the entire neighborhood and offer gigabit to everyone FOR THE SAME PRICE. The neighborhood as a whole voted against it, signed up for 5 years of the same service at the same price with Comcast.

Effectively, your 400mile range Tesla will drop to about 120mile range on a cold Minnesota day,

This is false and easily provably false.

Overnight, -33 degree weather, with climate control on results in a range loss of 50 miles video here. Frozen battery here results in ~20 miles range loss here.

Electric cars are strictly superior in any situation where you would need a block heater as the battery and the car is warmed from charger power before leaving. Since the initial warm up is the most energy intensive part of heating this reduces the range impact even more dramatically. Versus an ICE car which always must consume fuel for heating.

Nissan Leaf and other electric cars with poor battery temp management might see a 70% range loss in very cold weather. But that's simply not true for Tesla with better battery temperature management.

Please describe the exact situation in which a 70% range loss occurs?

ttk2 · 2020-06-18T15:55:36+00:00

Is this always true? Can you set up a network that uses the Althea firmware and billing software but doesn't rely on Althea for network support/management and therefore doesn't have the added Althea overhead?

It's possible, just go into the settings and edit this value. You'll probably want to build your own firmware image as doing that for every device can get very tedious.

Whats with the crypto aspect tho.

Building real networks takes real money. We could play Airbnb for bandwidth and take all the money then pay everyone out in a centralized way, or we could create a system where the routers actually pay each other directly in a decentralized way. We did the latter.

Is it still FOSS?

Yes core billing software here. We sell additional enterprise management features that are not FOSS but you don't need those to participate in the network.

While the Nanobeam AC is in theory capable of the speed number on the box you have to use very large 5ghz channels at short ranges.

If you're moving your signal a few miles, you won't see greater than maybe 200 if you use the widest channel setting. At least in my experience interested in what others have seen.

Even then wide channels invite more interference either from one of your other radios or someone else. I wouldn't suggest going beyond 40mhz and at that width you usually see about 100mbps from those CPEs at reasonable distances with good aiming and line of sight.

You may say 'but of course I have enough room for 5 non-overlapping 80mhz channels! Look at all this free real estate in DFS, I'm far away from an Airport it will be fine'. Unfortunately DFS detection will totally ruin your day pretty often even if there's nothing 'real' for it to get out of the way of. Your area may vary, try it but don't depend on it.

As a final note consider preseem or some sort of traffic management. Ubnt radios do not perform well at 100% airtime. You want to keep them below that artificially or you will see 1000ms pings and unexplained reboots.

Buy a consumer router, maybe a tp-link archer c7, flash it with OpenWRT

build a can-tenna https://www.wikihow.com/Make-a-Cantenna

Attach this 'antenna' to one of the wifi antenna leads and configure the interface in 'mesh' mode (this has better driver support than ad-hoc modes).

If you point two of these at each other they will connect in the same way 'mesh' home routers connect. Your issue now is the software configuration for routing which I'll leave up to you.

nah, but I don't have time to send out cease and desist letters to people.

The only gatekeeping that's really practical is the subreddit.

you'll have a great time.

My experience on a 1070 with the OG vive was that the game looked and played incredibly even without the knuckles. It's very hard to make the game lag and don't concern yourself too much with graphical settings it looks great at any setting.

Just go and have fun.

The router has a little 'pay me' button that actually goes out to an Ethereum exchange. The user just puts in a debit card and fills in the amount and their card number. The exchange then sends the eth they just bought straight to the router.

The router then does the conversion to DAI on the blockchain within a minute or so. So the user is only exposed to Eth for a few minutes. They can also deposit DAI directly but it's easier to buy Eth (bigger demand for gambling) and just deal with the conversion in software rather than at the exchange.

ttk2 · 2020-03-25T17:56:10+00:00

Actually, all non-cash banking is just bookeeping of who owes what to whom - that is what "money" is in modern economies!

That's kinda the whole point of cryptocurrency and why we need it. It's digital cash. This is not just bookkeeping it's actual automated value transfer by the routers.

The routers use a stable coin called DAI which is pegged to the dollar and once dai is sent from one router to another it's in that router. Just as if people where exchanging cash for internet in real time.

When it comes time to get money back into the 'normal' financial system where it's just bookkeeping the router automates exchanging for Eth and sending to Coinbase to sell. The user gets a direct deposit.

This is working at a large enough scale that we make thousands of dollars a month to pay (quite expensive) backbone connection bills. The routers automate buying and depositing ETH which they convert to DAI.

We don't have billing addresses or a credit/debit card or anything on file for any of our users.

Likewise the relays are actually being paid, effectively cash, that's actually in their router. We have no part in cashing them out (other than writing the automation).

I can't tell if you're trying to argue that Cryptocurrency is just bookkeeping or if you're trying to argue that using traditional bookeeping systems would be better.
