Meshtastic Overview
Meshtastic is an open-source, decentralized communication platform that enables long-range, off-grid messaging and data sharing using low-cost, low-power devices. It leverages LoRa (Long Range) radio technology to create a mesh network, allowing devices to relay messages without relying on cellular networks, Wi-Fi, or internet infrastructure. Meshtastic is ideal for remote areas, outdoor activities, or emergency situations where traditional communication systems are unavailable or unreliable.
Advantages
1. Off-Grid Communication: Meshtastic operates independently of cellular or internet networks, making it perfect for remote locations, disaster scenarios, or privacy-focused communication.
2. Long Range: LoRa technology supports communication between 2 – 10 miles in ideal conditions, far surpassing traditional walkie-talkies. In areas with robust mesh networks ranges can exceed 50 miles.
3. Decentralized Network: The mesh topology allows devices to relay messages, extending coverage as more nodes join, without a centralized network.
4. Low Power Consumption: Devices are energy-efficient, often running for days or weeks on a single battery charge, ideal for prolonged outdoor use. Add a small solar panel for continuous operation.
5. Open-Source and Customizable: Users can modify the software and hardware, tailoring it to specific needs, and the community-driven development ensures continuous improvements.
6. Cost-Effective: Meshtastic devices are affordable, often built on inexpensive hardware like ESP32 boards, making it accessible for hobbyists and professionals alike.
7. Versatile Applications: Supports text messaging, GPS location sharing, and sensor data transmission, useful for hiking, disaster response, or IoT projects.
Meshtastic empowers users with reliable, private, and scalable communication in challenging environments.
In this video, I take a closer look at FCC 47 CFR 15.247 and what it may mean for Meshtastic and MeshCore users operating LoRa radios in the United States.
As these platforms continue to grow, questions surrounding transmit power, dwell time, frequency hopping, digital modulation, and Part 15 compliance are becoming increasingly important. I break down the regulation, why it matters to the LoRa mesh community, and some of the potential challenges it creates for current hardware and firmware configurations.
The important takeaway is that this is not the end of Meshtastic or MeshCore. Developers and members of the community are actively discussing the issue and working toward solutions that can maintain the capabilities we enjoy while operating within FCC requirements.
Topics covered:
• FCC 47 CFR 15.247
• How Part 15 applies to LoRa radios
• Potential impacts on Meshtastic and MeshCore
• Transmit power and modulation considerations
• Why certain configurations may require another look
• Solutions currently being explored by the community
• What users should be paying attention to going forward
The goal of this video isn’t to create panic, it’s to help the community better understand the regulatory environment surrounding the technology we’re using and encourage informed discussion as solutions continue to develop.

If you’re searching for a rugged, field-ready Meshtastic/LoRa radio that thrives in extreme environments, the AT-Labs RM-1 deserves a serious look. Built for resilience and reliable communication, it’s designed to keep you connected when conditions get tough.
MeshCore is an open-source mesh networking platform and software protocol that lets low-power LoRa radios form decentralized, off-grid wireless networks for text messaging and data relay without relying on cellular or internet infrastructure. It’s designed to be scalable, structured, and efficient: devices can be assigned distinct roles like repeaters, companions, and room servers, and the system uses multi-hop routing to pass messages across many nodes in a controlled way, with a focus on managing airtime usage, reducing unnecessary broadcast traffic, and improving delivery reliability. MeshCore supports long-range communication, low energy use, and encrypted communications on common LoRa bands, making it suitable for emergency comms, outdoor activities, and larger planned mesh deployments.
Quick Comparison: MeshCore vs Meshtastic
Network model:
Meshtastic uses a “true mesh” where most devices automatically rebroadcast and flood messages to create ad-hoc paths, good for spontaneous networks. MeshCore separates roles (repeaters vs companions) so only designated repeaters forward traffic, reducing channel congestion and giving more structured routing.
Routing & scalability:
Meshtastic typically limits hops (e.g., default ~3, max ~7) and relies on managed flooding.
MeshCore supports much higher hop counts (e.g., up to ~64) and learns/uses efficient paths, which can be better for larger or fixed networks.
Ease of use:
Meshtastic is widely adopted, simpler to set up, and well supported by community tools and mobile apps. MeshCore may require planning (e.g., repeaters) and has a newer ecosystem, though offers stronger message reliability and control.
Compatibility: They cannot interoperate — a Meshtastic node won’t directly talk to a MeshCore node without switching firmware.
In short: Meshtastic is great for easy, ad-hoc off-grid communication; MeshCore aims for more controlled, scalable, and efficient mesh networking when you can plan infrastructure.
MeshCore offers the unique capability of solving or at least partially solving communication dead zones in rural areas. In today’s video I will be exploring the I-5 project and promoting the I-84 project to bridge Portland OR to Boise ID using LoRa Mesh Radio.
Does MeshCore really live up to the hype. After three weeks and thousands of miles driven, I have to say yes. The reality is that it is the mesh radio network “most people” have been looking for. The question is does it replace Meshtastic or Reticulum. The answer is it depends on what you want from your mesh radio network.
Reticulum is an open-source, decentralized networking stack designed for resilient communications without relying on traditional internet infrastructure. It can operate across LoRa, Wi-Fi, packet radio, serial links, and other transports, allowing devices and networks to communicate securely over a wide range of connection types.
The Zen of Reticulum explains the philosophy and design principles behind the Reticulum Network Stack (RNS), including decentralization, network sovereignty, resilience, and moving beyond traditional client-server thinking. It is a must-read for anyone who wants to fully understand the RNS project, because it explains not just how Reticulum works, but why it was designed the way it was. The official Reticulum documentation itself recommends reading the Zen to understand the project’s foundational philosophy and goals.
Ratspeak is a Reticulum-based communication platform built for private, resilient messaging without accounts, central servers, or traditional internet dependency. In this video, we take a first look at Ratspeak, its role in the Reticulum ecosystem, and how it supports communication across transports like LoRa, Bluetooth, local networks, TCP, and supported mesh hardware. We’ll cover what Ratspeak is, why it matters for off-grid and emergency communications, supported devices like desktop, mobile, T-Deck Plus, and Cardputer, and how it fits into a larger movement toward decentralized, user-owned communications. Topics covered: Reticulum, Ratspeak, LXMF messaging, LoRa mesh communication, off-grid messaging, emergency communications, private communications, decentralized networks, and resilient comms.
