INTRODUCTION TO MESHTASTIC FOR AMATEUR RADIO OPERATORS by Matt Patrick, VE6AZX

Meshtastic is an open source packet radio protocol using low-power, long-range radios. This presentation will introduce the Meshtastic project from an amateur radio perspective: we will demonstrate how to get set up with some inexpensive hardware, and show some of the infrastructure and activity on Calgary’s mesh network. This system provides text communication without any other infrastructure. This is an independent self-forming mesh network that works if the power is out and / or the cell phones are down. You don't have to be a licensed ham to set up a Meshtastic node. Another piece in your emergency planning toolkit, and it's just plain fun to play radio with tiny devices.
