> Are there decent wifi communicators on the market? I looked into some Lora projects for this but they never seem to actually ship or get past prorotype
Yes, 100%. Meshtastic and Meshcore both do this, but I'd recommend Meshcore. Here in the Seattle area we have a network that fairly reliably delivers messages from Canada through the Seattle metro area all the way down to Portland. Fully encrypted with dual key cryptography. Meshcore uses a different strategy than Meshtastic, which enables Meshcore to work more reliably. To see what's happening in your area for Meshcore see https://analyzer.letsmesh.net/map
Is very fun to set up a repeater for under $50 and see a noticeable difference in the coverage area. Is a fun technical project that combines the best of hiking/walking/driving geocaching style, ham radio (but without a license requirement), antenna building, and more. I'm getting acquainted with people in my neighborhood too which is a bonus.
Figuring out what hardware to buy that'll actually work can be a challenge, to get started search amazon for "heltec v3" and make sure you get something that includes a battery, and you'll see 2-packs of radios for $60. There's a web flasher at the above link that'll put the software on the radios for you.
