LEHIGH VALLEY MESH
01 / 03
Off-grid communication
Communicate without depending on cellular service, commercial internet, or a centralized provider.
Our mission
Lehigh Valley Mesh is a collaborative effort to design and deploy decentralized mesh communication systems throughout the Lehigh Valley. Using open hardware, LoRa-based mesh networks, and amateur radio techniques, we focus on practical, real-world deployments that work when traditional infrastructure does not. Join a growing community of makers, radio operators, and technologists pushing mesh communications forward.
MESHCORE / NORTH AMERICA
Start on the same frequency.
For LVMesh companions, repeaters, and room servers, configure the radio with the LVMesh settings shown here. Every radio on the network must use matching RF parameters.
TX POWER IS DEVICE-SPECIFIC AND IS NOT PART OF THIS NETWORK PROFILE.

THE NETWORK
Independent communication. Regional reach.
02 / 03
Long-range LoRa
Efficient sub-GHz links make strategically located, low-power infrastructure practical across regional terrain.
03 / 03
Community infrastructure
Repeaters hosted on homes, rooftops, towers, businesses, and elevated sites create useful regional paths.
PACKET PATH / MESHCORE
A message finds its own way.
A companion sends the packet, repeaters relay it, and the destination receives it. Observers listen separately for network telemetry.

HOPREACH / REGIONAL COVERAGE
See where the network can reach.
Explore terrain-aware coverage for LVMesh’s primary 500 kHz network and the surrounding 62.5 kHz mesh. Filter the preview by frequency and bandwidth, then open the same selection in HopReach.
MESHMapper / ABE COVERAGE
Map what actually works.
Wardriving pairs phone GPS with a Bluetooth-connected MeshCore companion to record where repeaters are heard, signal strength, and whether a path works both ways.

FINDWeak edges + gaps
IMPROVERepeater placement
Field observations let us compare measured coverage with HopReach predictions, prioritize useful repeater sites, and verify improvements after a deployment changes.
DRIVE SAFELY Configure the app before moving and let a passenger operate it. GPS coordinates upload to MeshMapper rather than being broadcast over RF by default.
