What Is Store and Forward? Store and Forward (S&F) is a Meshtastic server module that buffers messages for nodes that are temporarily offline. When a client node comes back within range, the S&F server replays the messages the client missed while it was away. ...

Why Position Accuracy Matters An accurate position lets your repeater appear correctly on meshmap.net and in the Meshtastic app's node list. Other operators use your node's reported position to plan coverage, model signal paths, and verify that packets are act...

New York City / Tri-State Area Geographic Context NYC is one of the most RF-challenging urban environments in the world. Dense skyscrapers block ground-level propagation but simultaneously create outstanding elevated repeater positions. The five boroughs pres...

Washington DC / Baltimore Metro Geographic Context The DC/Baltimore metro straddles the Piedmont plateau as it transitions eastward to the Atlantic Coastal Plain. The Appalachian foothills to the west — including the Blue Ridge and Bull Run Mountains — provid...

Atlanta / Southeast Geographic Context Atlanta sits in the Georgia Piedmont at approximately 1,050 ft above sea level — an elevation that already provides a propagation advantage over the Coastal Plain to the south and east. Two prominent landmarks bookend th...

Texas Gulf Coast / Houston Geographic Context Houston sits on the Texas Gulf Coastal Plain at near sea-level elevation — the city and surrounding region are remarkably flat. This lack of terrain variation means that coverage is almost entirely determined by a...

Why Update? Meshtastic releases updates frequently, delivering bug fixes, new features, and performance improvements. For best compatibility with other nodes on the mesh, aim to stay within 1–2 major versions of the current release. Running a very old firmware...

Update Frequency MeshCore releases firmware periodically. Major releases introduce new features and architecture improvements; point releases fix bugs. Check the changelog at github.com/meshcore-dev/MeshCore/releases before updating to understand what has chan...

How Meshtastic Encryption Works Each Meshtastic channel uses AES-256-CTR (counter mode) encryption with a 256-bit pre-shared key (PSK). Any node that has both the correct channel name and the correct key can decrypt messages on that channel. Encryption is end-...

Position Privacy By default, Meshtastic nodes broadcast GPS coordinates to the entire channel at regular intervals. Your approximate location is visible to all channel participants. If your node is on the Default public channel, your position also appears on a...

Why Model Before Deploying Walking a coverage area with a radio after installing a repeater is valuable ground-truth — but it is expensive if the site turns out to be wrong. Free online tools let you model RF line-of-sight and rough coverage before committing ...

Why Field Test? Even the best RF prediction tools are only as good as their terrain models. Buildings, vegetation, and local obstructions can significantly degrade predicted coverage. Field testing confirms what the models predict — and reveals the surprises t...

LoRa Channel Capacity LoRa is a low-data-rate technology. Unlike Wi-Fi, the RF channel is shared by all nodes simultaneously using a CSMA-like approach combined with Meshtastic's flooding mesh mechanism. Understanding channel capacity helps you design a networ...

Geographic Context Metro Vancouver sits between the Coast Mountains to the north and the US border to the south, with the Fraser River delta extending to the east. This geography provides exceptional repeater sites on the North Shore mountains: Grouse Mountain...

Geographic Context Toronto sits on the flat north shore of Lake Ontario at roughly 250 ft elevation. The Niagara Escarpment runs to the west (rising 200-300 ft above the lake plain near Hamilton and Burlington), and the Oak Ridges Moraine rises to the north, p...

Geographic Context Ottawa sits at the confluence of the Ottawa and Rideau Rivers at roughly 250 ft elevation. Directly across the Ottawa River, the Gatineau Hills in Quebec rise to 1,400 ft, providing commanding elevated positions that overlook the entire Nati...

Geographic Context The Twin Cities metro sits on relatively flat terrain at 800-1,000 ft elevation. The bluffs along the Mississippi River -- rising up to 300 ft above the river level -- provide the best elevated positions in the metro. The broader Minnesota l...

Geographic Context Salt Lake City sits in a bowl valley between two mountain ranges: the Wasatch Range to the east (peaks at 9,000-11,000 ft) and the Oquirrh Mountains to the west. This enclosed geography creates both exceptional elevated repeater opportunitie...
