All modules seem to be us-only. Is there a modules usable in eu frequency?
The airtime restrictions make it pretty much useless in the EU

#32I played with HaLow for a while but the only stuff I could get here in the UK was some undocumented crap from AliExpress, anything more robust looking only seems to work in the US. A shame because it’d solve a infrastructure challenge I have to juggle each year

Meshtastic has been popular, but relies upon a terrible implementation of a mesh -- and it's vastly oversold on its capabilities. I understand some hams run a meshtastic repeater primarily to convince meshtastic users to become hams.
It's worth commenting to me that MeshCore performs much better than Meshtastic at scale and as an emplaced deployment. We have a very active network of about 60 nodes in the Boston area which feels similar to iMessage in deliverability and speed. But yes, it can't realistically be compared to something like a "real" MANET system with $10k radios that can do something like 100mbps data rates. It is dramatically more a…
MeshCore is a huge step in the right direction. Especially over Meshtastic which is very poorly designed.
However MeshCore makes one fundamental choice which is severely limiting. It uses a single LoRa discriminator and channel for all nodes. That said, LoRa limitations pretty much force this choice.
This, limits a typical network (3 repeaters) to about 500 messages/hour. The throughput scales inversely by how many repeaters you can hear.
The code does try to adjust down the TX power of a repeater in repeater-dense networks, which probably helps keep throughput consistent for a while.
For these things to work at scale they either need something other than LoRa (which is quite novel, but limited) or they need to figure out how to use LoRa in a way which allows for more channelization.
Until then, the “one transmission at a time on the air” in these very low baud networks is severely limiting.

#34Ever since 802.11ah devices started appearing I've thought it would be perfect for partnering inside wireless IP cameras... and hell, make them mesh together with something like this so each one configured on your network extends the range of the others in it's area. Streaming 720P H265 is easily doable at the speeds the networks achieve for a few cameras, and the range would be perfect for perimeter monitoring most properties ala farms & industrial parks.
This device however - an entire Raspberry Pi + hat for a router to do..? ... seems like a solution in search of a problem to solve.

Semtech announced recently that their new chips will be able to decode all spread factors on a specific bandwidth and center.
That being said, that would allow new LoRa nodes being capable of listening on effectively 8 different channels (that dont conflict) and transmitting on 1.
Re: OpenMANET Wi-Fi HaLow open-source project for Raspberry Pi–based MANET radios
#36MANET is one of the protocols I was involved in implementing for a certain network protocol suite back around 2012. Mesh routing protocols only work for the most limited of use cases. They don't know about the capacity of the underlying wireless network and basically fall apart when things are congested or there are radios with poor reception. QoS is implemented far better in modern cell phone networks, and if the ro…
Interesting! If someone with a math background (but not a CS background) wanted to dig deep into learning about mesh networking protocol theory - do you have any recommendations for learning resources or places to get started?
I've long imagined that a content centric mesh network approach would be a better starting point than what we've built up currently, but it seems like such a deep and mysterious subject and I have no idea where to even begin to get started.

#37I wonder if you could air drop these at some location, it wouldn't last long but way to deploy the nodes.

I feel like a HAM license is something of an inevitability of my future, although I don’t have any practical need for one. Catching satellite signals in my backyard is a lot of fun.
The technician license is honestly "good enough" for a lot of people. Particularly now that the digital voice modes allow people to chat across countries through the internet. DMR/SystemFusion/MMDVM are things you might want to research.

I use it for hiking, its great.
How do you use it for that?
Can design then export routes from any geospatial tool like CalTopo, AllTrails, or even WinTAK directly to your ATAK device. Then in ATAK you can use it basically as something like AllTrails on steroids, including offline map caching, route guidance, markers, tracking etc... even geotagged photos. This can be synced across multiple devices among friends using a TAK server. It can also be used for off grid communications and tracking between hikers via something like Meshtastic, which I use fairly regularly with my partner out camping well outside of cellular coverage.
ATAK is not necessarily the most intuitive UI, but it's crazy powerful for doing basically anything outdoors.

Oh that sounds quite nice, thanks for sharing!
