Side note: how do y'all carry your antennaed nodes while out and about? Like to the gym or errands

I really like the idea and I want to get into meshtastic, so that I can communicate in case of an emergency.

Two questions:

  1. is meshtastic the only protocol, or are there others?
  2. does the community take the risk of an EMP seriously, or can I expect to be the only one with a working device after an EMP?

  1. There are two others that I know of: Meshcore, and reticulum.
  2. In my short time in the scene, I haven't seen anyone talk about anti-EMP measures they have taken.

Its my understanding (I may be wrong here) that the antenna wouldn't be able to be exposed during the initial EMP anyways, so you'd need to keep a stash of nodes in a Faraday cage to deploy after an EMP

Most of these devicesbwould definitely gsr damaged or disabled by an emp. The voltage is very small on most of these devices.

Yeah, that's where the Faraday cage would come in to play

Thanks for answering

  1. Are those protocols interoperable? Or are they fighting for individual market dominance?
  2. Sad, but that’s often the case. And yes, you’d need to store a couple of devices in a hell of a faraday cage, in hopes they will survive an EMP detonated above your head. In the end, this is one of the main use cases I can see. If you use those devices today, it is similar to amateur radio: Fun and nerdy, but not needed.

  1. Semi, there are some network bridges that translate packets in to ones that the target network expects. Meshtastic has the "market share" in my area, and is completely FOSS, so I gravitate towards it. Reticulum seems very interesting but doesn't have high adoption at this time.
  2. Yeah, I'm sure that some people do. Cell networks may also go down if overloaded during a natural disaster, but yes this is mostly a hobby.

I'm planning on leaving a few nodes in advantageous locations near families work and home to ensure we can coordinate if cell goes down, and will get around to stashing a few away in a cage just in case
