In russia they have limited internet now. something like mestastic is something everyone would need to make sure we could have communication even though someone tried to limit it.
Is russia densely populated enough to be able to make it work? Around me I'm having trouble getting a connection to any other nodes because there isn't a critical mass of other people running mesh nodes and there's a hill between me and the next city
In that case I think Reticulum would be the better use case as it's encrypted from the start.
https://reticulum.network/manual/whatis.html
Reticulum is an open-source, cryptography-based networking stack designed to build secure, resilient, and decentralized low-bandwidth wide-area networks using readily available hardware. It operates efficiently over various mediums like LoRa, WiFi, Ethernet, and serial connections, enabling autonomous communication that cannot be easily censored, surveilled, or controlled
There are lot of Meshtastic nodes over Moscow and some larger cities.
Since wired internal connection inside Russia is not limited, so _for now_ there is no need in dense LoRa meshes - Meshtastic mqtt transport will work just fine.
Are you trying about cross-border communication in event where the internet is somehow blocked near the border?
I'm on a fence about this.
First, the biggest issue r/n is the concern that external internet will be limited to a point of no return, for this meshtastic is quite useless because to go across the border you need powerful transmitters and risk of placing and maintaining them near the border. In russia this is not only risk of going to prison but also being literally shot if border patrol/FSB overreacts. Even if you're successful bandwidth is miniscule compared to what a modern country needs to communicate internationally.
Second, due to Ukraine piggybacking on cellular networks for drone targeting/control cell service is frequently disrupted by authorities in the areas of a likely attack (it's obviously as effective as this sounds compounded by general incompetence of the government). While they cannot shut it down completely because russia still doesn't want to go back to the stone age, this concern is largely non-existent for meshtastic though. If it becomes widely popular and coverage expands, it also could be used by Ukraine as a control network, and in this case I would expect russian authorities to just jam the whole frequency range and be done with it. So the moment it becomes viable alternative is the moment it will be shut down.
