    I know to you guys its normal but I live in the Sonora desert of Arizona in one of the hottest places on earth. Today in only 6/3 its already well over 100 degrees. I was blown away to see how dark it was there with all that fog, Id imagine you guys spend alot of time in doors? Out here its sunny about 350 days a year, the only fog we get is during Monsoon season when these massive storms roll across the desert. Its really truly aww inspiring to see the sheer power of God. Ive been looking into trying lora devices to use as a com system in several of the Turquoise mines I own, ( My hobby and former career was engineering ) I was hoping lora could be used with repeaters in the tunnels so someone on the outside can still have comes with my workers down below but im not so sure this would work without a bunch of repeaters idk? I do know theres a similar system out there that uses wrist band coms for miners to keep track of them underground but they wanted 50K for each arm band for the men and 250k for my unit that acts as a sorta base station. Frankly small mine owners like myself cant afford these crazy prices however I see how valuable this could be during a cave in or someone lost underground which does happen so ive been trying to figure out a system like lora. Any suggestions would be MUCH appreciated!!!

    Last week, I received 6 of the much cheaper - and smaller - HelTec v3 units that can also run MeshTastic for experimental purposes.
    Most MeshTastic units can be paired to a cell-phone which in turn runs an app that can provide delivery notifications. All MeshTastic software is open source, however, the LoRa radio remains proprietary.
    At best, a mesh can be up to 80 units in size and provide a total data through-put of about 50kbps. For an underground station, that could be plenty-enough to provide a text data route from the platform to the surface for most users.
    Your video is a great demo of what can be achieved - and what should be provided - in an underground railway environment - especially if only for emergency services

    Surprised no cell/mobile coverage on a London line. In Australia, NSW we mostly have major city coverage on urban underground lines, via directional antennas. T-Deck is not fully functional yet. Long/Slow channel setting has had minimal testing. 3dBi dipoles antennas would be better perhaps. I'm assuming RX gain boost is on. Nice video. Merry Christmas!

      Some frequencies behave differently in different ways in different locations. For example, UHF is better in built up areas for local communications, VHF better for out in the open. 4m 70MHz is outstanding when it comes to the way signals travel compared to 2m and 70cm! You also find that only certain frequencies work for cave rescue too, or certain frequencies can be heard underground better than others. RF is fascinating to experiment with as you can also try different types of aerials etc.
      In a tunnel the signal will bounce around and reflect off the walls. A bit more power would help.

    This is awesome! I have tried using the T-Deck "simplex" to a second T-Deck with Meshtastic but I guess I keep getting the settings wrong. Love to know your setup.

    I don't know much about radio/mobile signals, but what is there to stop normal mobiles phones with Bluetooth, WiFi, 5g capabilities, etc. being utilised (hacked?) to work as a peer to peer based mesh network somehow. I guess the ranges might be smaller but everyone has a smartphone with these network capabilities so the mesh network could potentially be a lot more densely populated.

    • @andykirby
      @andykirby  Рік тому +1

      It's possible but bluetooth and wifi was never intended for super long range, fine if you have lots of devices close by you could use Bluetooth LE.
      LoRa is better for this purpose though, that's why it works so well.

    Governments don't want citizens using private communications. So they only approve vetted and cooperating private businesses to provide that service. I think mesh networking for local and laser for point to point when talking to different meshes separated by a significant distance, is the answer. Since laser communication is very directional and not accessible to an outside party, it might be legal in some sense.

      Ah yeah, that's why they de-regulated citizens band and amateur radio licencing exists.
      Wonder what they do if they actually want us to have something?
      Oh and IR laser is late 90s tech for point to point computer network links between buildings. It has been done.

    For us above ground people. Can you tell me a bit about the protocol. Is it a network offered by the transit company or something you cooked up? Is it peer to peer, like a walkie talke or must there be some sort of access point?

    Am I missing something? A decent pair of walkie talkies would have the same comms RF wise. If subterranean doesn't connect to above ground why have you not tried it with those devices. Easily confused. Happy Christmas.
