<div dir="auto">I couldn't have said it better myself. So many ideas come to mind I don't want to bake them all out right now. But once more clearly thought out (by me...)<br><br></div>

<div dir="auto">Tell me also please - do we have existing technology (frequencies, products?) to accomplish such a "...cross-continent Amateur RF Terabit Digital Backbone..." yet? Or do you mean with regards to overall capacity over redundant links and nets as apposed to that capacity in a single beam/hop? Curious about your thoughts...<br><br></div>

Great ideas in there!

I like being able to layer different technologies and experiment with different topologies.
</div>
<div>
- A static/intentionally engineered cross-continent Amateur RF Terabit Digital Backbone (anyone want to help coordinate a national weekend event to see how far it could go?)
</div>
<div>
- A static/intentionally engineered mesh, ala aredn to cover counties
</div>
<div>
- A dynamic, fault-tolerant, delay-resistant, mobile-capable mesh, ala InterPlaNet to fill in the gaps between counties or states (never underestimate the bandwidth of an SSD or 2 on a RaspberryPi 4 driving cross-country in a Tesla)
</div>
<div>
- Local BBHN/AREDN meshes and New Packet Radio (more of a star topo) to serve areas of concern, especially between EOCs, Hospitals, Shelters, Schools, etc.
</div>
<div>
- Good old packet as "interface of last resort" with store/forward files, email, text/sms, APRS, "Virtual Assistants", interface to D* digital services, etc
</div>
<div>
<br>
</div>
<div>
There are so many aspects to the various ways we can experiment as amateurs and actually contribute to the technologies involved in each.

<br> Here is an idea on how they are building out their network in Slovenia.
<br> Maybe there are some good ideas that will catch your fancy.
<br>
<br>
<br> Maybe a concrete example of our current and future S5net in Slovenia
<br> together with our expectations from broader 44net community could help.
<br>
<br> As you can see from schema of current and planned links:
<br>
<br>
<a href="https://groups.io/g/nbp/topic/s5net_stanje_in_plan/79358609" rel="noreferrer" target="_blank">https://groups.io/g/nbp/topic/s5net_stanje_in_plan/79358609</a>
<br>
<br> we are building nationwide radio network, linking our hills with DMR
<br> repeaters into a fully redundant network, as much as possible
<br> independent from public internet. Main goals:
<br>
<br> - reliable DMR, EchoLink, APRS network,
<br> - emergency communications for our communities,
<br> - for radioclubs and individual radioamateurs,
<br> - open for experimentation and innovation into the future.
<br>
<br> Besides mesh-like radio layer there is also a star-like ground layer
<br> connecting gateways to public internet via tunnels to main router in our
<br> capital. VPN server is established to connect easily and from everywhere
<br> to the S5net. Offering L2TP and SSTP VPN access which is easiest for
<br> most people.
<br>
<br> We are using Mikrotik routers and Wifi antennas from Ubiquiti and
<br> Mikrotik. But we care not to become too dependent to any vendor.
<br> Sticking to standards is a key here.
<br>
<br> We allocate our 44.150 IPs in the following way:
<br>
<br> - /28 with reserve /28 to each hill,
<br> - /24 with reserve /24 to each interested radioclub,
<br> - /28 with /28 to a LAN of each interested radioamateur,
<br> - static /32 and dynamic /32 (like for mobile phones) to each interested
<br> - more for specific needs (for experimentation, some IoT projects etc.)
<br>
<br> Allocation is not forever, it will probably cease 5yrs after inactivity.
<br>
<br> OSPF protocol routes traffic in S5net. Therefore we are free to raise
<br> any subnet anywhere in the network. For things like roaming..
<br>
<br> BGP to the public internet for a whole national 44.150 allocation is
<br> something we are thinking about. Like in Netherlands as I understand?
<br> All access from outside disallowed by default, switched on manually for
<br> each individual IP or subnet.
<br>
<br> For peering we are talking with our Academic network ARNES, because they
<br> are similar in philosophy and have a lot of knowledgeable networkers
<br> willing to help.
<br>
<br> To interconnect with HAMnet in neighbor countries we also plan to use
<br> BGP with a whole S5net as one AS with private ASN.
<br>
<br> Our DMR master server is multihomed - with public access for hotspots
<br> and with 44 IP via S5net for DMR repeaters.
<br>
<br> Hope this helps a bit
