MeshCore - Lehigh Valley Mesh

Modular, Extensible Mesh Networking

MeshCore is an open-source mesh networking platform designed to be flexible, extensible, and protocol-agnostic. MeshCore focuses on creating resilient, decentralized networks that can support messaging, telemetry, monitoring, and custom integrations across a wide range of hardware and deployment models.

MeshCore is built for experimentation, infrastructure monitoring, and advanced use cases where adaptability and visibility matter.

What Is MeshCore?

MeshCore is not a single-purpose messaging system.
It is a modular mesh framework that allows nodes to form decentralized networks while supporting multiple roles and functions within the same mesh.

MeshCore supports:

Peer-to-peer messaging
Network observation and monitoring
Telemetry and data forwarding
Integration with external systems
Custom services and applications

Nodes automatically discover peers and route traffic without centralized coordination.

Why MeshCore Matters

Many mesh systems are optimized for one specific function. MeshCore is designed to be adaptable.

MeshCore provides:

A flexible foundation for custom use cases
Visibility into mesh health and performance
Support for mixed node roles
Infrastructure-friendly deployment options
Independence from internet connectivity

This makes MeshCore well suited for community infrastructure, research, and resilience-focused deployments.

How MeshCore Works

MeshCore nodes run open-source firmware that manages:

Node discovery
Routing and relaying
Message handling
Telemetry exchange

Depending on configuration, nodes may act as:

Relays
Observers
Gateways
Application hosts

This role-based approach allows a single mesh to support both operational traffic and network insight without creating dependencies.

Common MeshCore Node Types

Relay Nodes

Relay nodes form the communication backbone of the mesh.

Forward traffic between nodes
Extend coverage and reliability
Typically installed at fixed locations
Optimized for continuous operation

Relay nodes are often deployed at elevated or strategic sites.

Observer Nodes

Observer nodes monitor the mesh without generating user traffic.

They provide:

Network health visibility
Routing and performance insight
Status and telemetry collection

Observer nodes are ideal for infrastructure locations where monitoring is valuable but user messaging is not required.

Gateway Nodes

Gateway nodes optionally interface the mesh with other systems.

Possible functions include:

Feeding local dashboards
Bridging data to servers or applications
Integrating with monitoring or alerting systems

Gateways are optional and do not create a dependency on external networks.

Portable and Experimental Nodes

MeshCore supports rapid deployment and experimentation.

These nodes are used for:

Temporary coverage
Field testing
Proof-of-concept deployments
Custom development projects

Power and Long-Term Operation

MeshCore nodes are designed for low power consumption and unattended operation.

Common power options include:

Battery systems
Solar power
USB or fixed power sources

This enables long-term, grid-independent deployments with minimal maintenance requirements.

Line of Sight and Coverage Considerations

MeshCore performance depends on the radio hardware and frequency bands in use.

Depending on configuration:

Some deployments benefit from clear line of sight
Others tolerate partial obstructions
Antenna height and placement remain critical factors

MeshCore’s flexibility allows deployments to be adapted to real-world terrain and infrastructure constraints.

Licensing and Regulations

MeshCore itself is radio-agnostic.

Regulatory requirements depend on:

Frequency bands used
Hardware selection
Local and national regulations

When deployed on amateur radio spectrum, FCC Part 97 rules apply.
When deployed on unlicensed spectrum, applicable unlicensed regulations apply.

Users are responsible for compliance.

MeshCore and LV Mesh

Within LV Mesh, MeshCore serves as a foundational and experimental platform.

MeshCore is used to:

Explore advanced mesh behaviors
Monitor network performance
Support infrastructure-focused deployments
Integrate mesh networks with local systems
Develop custom applications and tools

MeshCore complements other LV Mesh technologies rather than replacing them.

When MeshCore Is the Right Choice

MeshCore is especially well suited when:

Custom behavior or integrations are needed
Network visibility and monitoring matter
Infrastructure-style deployments are planned
Flexibility is more important than simplicity

It may be more complex than entry-level systems, but offers greater control and extensibility.
