[bars] Is anyone familiar with mesh networks ? from W1LPG

[geoffreyf at comcast.net]

Referring to hacker wet dreams is really not a good argument. Examining the specification or reading others examination of the 5G / 6G specification might be a lot more work than you wish to do - but it's the only basis for useful comment about hacker nocturnal emissions.  Actually, it's a basis for why that is utterly irrelevant to the question about Mesh networks for amateur radio.

A simple explanation of mesh was requested, and that simple explanation is all transceivers are repeaters.    Then there are problems with loop repeating, solved by algorithms.  Asked and answered.

This kind of colorful ejaculation of ideas is why these list serves can be very tedious.

"Now imagine if your cell phone also sent information to other nearby cellphones and nearby cell phones could route messages, calls, or data through your cell phone to reach the towers. How’s it is a mesh network."

You just described a hacker's wet dream.

Imagine the cell phone system. You phone just receives data from the cell phone towers. Now imagine if your cell phone also sent information to other nearby cellphones and nearby cell phones could route messages, calls, or data through your cell phone to reach the towers. How’s it is a mesh network.

If you are familiar how the National Traffic System works to send radiograms, that is technically a mesh network. I can create radiograms and any operator can receive them and forward them onto the final recipient but I also accept radiograms from other to sent them either to the recipient or another operator to continue it on its way.

That’s my best simple explanation. There are a lot of more complex topics beyond this to increase efficiency and improve resilience of the mesh but that’s beyond basics.

gives me too much.  I want a very simple, basic explanation
for something which could be the next FT8 ???
