Meshtastic is an open-source project that uses LoRa radios to create encrypted, decentralized mesh networks. 
It enables text and data communication without cellular, Wi-Fi, or internet infrastructure.

Meshtastic offers:

• 📡 LoRa Mesh communication without Wi-Fi, cellular, or Bluetooth.
• 🔐 Encryption for secure channels.
• 🌍 Community-driven networks for emergencies, experiments, and exploration.

👉 TAMI Meshtastic Workshop – Meetup: November 2, 2025

  Disclaimer:
  Meshtastic configurations and deployment for this workshop are designed around the legal ranges and information published by the Ministry of Communications for LoRaWAN. 
  However, as there has been no updated official guidance specific to LoRa in Israel for several years, 
  the community and Israeli users are working with the best possible configurations within firmware limitations to remain aligned with the current amorphic legality.
  All information shared in this workshop—and within the community—is publicly available for anyone to research independently. 
  The workshop itself will be ~85% hands-on, and each participant is solely responsible for their own use of Meshtastic.
  
  Participation in the Meshtastic community and activities is entirely voluntary. If these conditions do not meet your needs or interests, you are under no obligation to join or continue.
