We should all know at this point that you should not be bringing your cellphone to a protest. (if you don't know this please read up https://www.404media.co/inside-ices-tool-to-monitor-phones-in-entire-neighborhoods/ ) So what do you do for communications? In the 915 mHz band there is something called Meshtastic. It is a mesh text messaging system that can be encrypted. You will need dedicated hardware that doesn't require a phone (I am most interested in the LilyGo Tdeck https://lilygo.cc/products/t-deck-meshtastic) It's nearly plug 'n play #uspol #protest #Chingalamigra
