Installing Wifi 900 Ft Underground In An Abandoned Mine

“Ghost Town Living”

It was a historic day at Cerro Gordo! We set off to bring Internet 900 feet underground to have communications, research, and more down in the abandoned mines.

It was an adventure, as all things are up here.

Check it out as I descend 900 feet underground to bring Internet.

  1. Should have contacted Linus Media Group. Could have done a collab and got it for free from his sponsors along with way better equipment. Might even end up with a Noctua ventilation system and RGB.

  2. Way to complicated done with coax and also not needed if you have power down there now. I used drilled pair cable to connect two water Reservoirs with their controls more than 1200m with a P2P DSL (cots less than $300!!!) Allnet VDSL2 modems which on both end then converts to Ethernet. Stable connection since 8 years now with almost 100Mb connection running 2 Full HD surveillance cams 24/7 plus the full communication between two Siemens S7 SPS systems. These drilled pair cables are like ethernet or telephone cable. In fact you could even use normal power line as long as you have 2 wires. It will suffer a little bit on the long run but still will work. I tested it with up to 800m of normal power cable and still got 50Mbits.

    But what I have done would be to have on every major level a rugged outdoor switch as you know have the power down there. Why? Because ethernet can easily transport 1Gbit over 100M, actually I had runs almost 150m long with no issues getting still 1Gbits! So you connect from switch to switch and always get 100m easily out of simple normal ethernet cable which is also available in rugged form. Use POE switches and you then even can power APs way down the longer runs of the mine by simply just lay normal ethernet cable and everything connects back to the Elevator line.

    That way you could eaily establish also a walkie-talkie or alike interfaces and have more communication possibilities. Mumble.info would be an open source or even teamspeak!
    Do not forget to put an UPS at the top for safety!

    Using good ethernet cable with shielding even protecting stuff can be reduced as the shielding itself is making the wire really rugged so conduits are not really needed, and even if a break occurs, ethernet is also so simple to repeair nowadays. Ask me how I know, haha Had to fix so many cables over the years and ethernet is really simple. It's also ultra cheap and no, you do not need Cat 7 cables for that. Cat 5e would be enough for what it is for and that you get even as private consumer in boxes of 300m runs. Put a switch every 80-100m and from there to next or use this ethernet cable as mentioned with a Allnet VDSL2 point to point modem and get 1Gb at the lowest level of the mine.

  3. Congratulations, Brent! You've come a long way!
    Hey, I'm not sure if anyone else noticed, but I don't think you were alone down there at the 900 level. At 18:42, when you were talking about the wi-fi, I heard a man whisper, "Imagine that", over your talking, just plain as day, and that's All he said. That's pretty cool, Brent, perhaps you'll be able to film the ghosts down there now too!
