Inexpensive Meshtastic Long Range (LoRa) Radios, No License Rqd

[Adonsa7100]

Long Range (LoRa) shares the 915 MHZ band with Ham Radio and other services in the US.  In Europe and other countries the 800MHZ and other bands are used. Meshtastic is extremely popular in UK.  No license is needed,  OR,  Ham License is applicable too. The Station G-2 Node does both.  

Bottom Line:  Internet is NOT required for day to day operation.  The nodes (transceivers) are cheap!!!  Encryption is possible for non-ham radio uses. 
Let's take a look at a much better description than I can provide. 

Meshtastic® is a project that enables you to use inexpensive LoRa radios as a long range off-grid communication platform in areas without existing or reliable communications infrastructure. This project is 100% community driven and open source!

Meshtastic utilizes LoRa, a long-range radio protocol, which is widely accessible in most regions without the need for additional licenses or certifications, unlike HAM radio operations.

These radios are designed to rebroadcast messages they receive, forming a mesh network. This setup ensures that every group member, including those at the furthest distance, can receive messages.
