Բացատրություն
Amateur mesh nodes are ordinary commercial wireless routers whose firmware has been replaced with amateur mesh firmware that sets the channel, bandwidth, power and identification for amateur operation and adds the mesh routing. Packet radio TNCs on 2 meters or 440 MHz are far too slow, and EchoLink is a voice-over-internet linking system, not a mesh.
