FreqMapper Help

A FreqMapper trip: a phone, a radio, and independently observed coverage across a valley.

FreqMapper is a community map for measured Meshtastic coverage. It is for the people who look at a trailhead, back road, neighborhood, or valley and wonder: would the mesh make it from here? A result becomes coverage evidence only after an approved MQTT Watcher reports a controlled mapping packet or normal mesh Position Packet received over RF.

What FreqMapper does

With the FreqMapper app on iPhone or Android, a mapper connects a Meshtastic radio, starts a trip, and lets the phone record its own GPS position. The app sends low-rate, tagged tests on the shared wardriving channel. If an approved Watcher independently reports the same packet, FreqMapper can place a verified result on the map.

That keeps the map useful for real-world planning without treating an unobserved coordinate as coverage. Controlled mapping tests and normal mesh traffic retain separate evidence records even when they use the same public signal-quality colors.

Important

A normal Position Packet creates Position Packet coverage only when an approved Watcher actually receives it over RF. It does not create mapper credit. A relayed packet proves mesh delivery, while its RSSI/SNR describes only the final hop into the Watcher.

New regions are not open for self-service sign-up yet. Ask the FreqMapper community or your regional team for a current enrollment code. The guided path is the same on iPhone and Android:

Looking for a region?

A public region directory is available on the map, but self-service regional sign-up is not. Enrollment codes can expire or be revoked. If you would like to help establish a new area, read Start a FreqMapper region.

The one rule that matters

A coverage cell is verified only when all three things line up:

  1. The mapper's phone supplied the location for a tagged mapping test.
  2. The packet has a matching identity and timestamp from that test.
  3. An approved feeder independently uploaded a receipt from the same region.

Several independent feeder receipts can increase confidence. The lines and receipt lists show who reported hearing the test; they do not prove the exact over-the-air route through a Meshtastic mesh.

A few useful expectations

  • The app's map shows your own current session's route, sent-test dots, and verified cells. It does not turn someone else's trip into your live route.
  • The public map is the shared regional snapshot. It refreshes with verified TX coverage and privacy-filtered aggregate RX cells from everyone.
  • Watchers can be useful even without a map position. They can verify a test; they simply cannot be shown with an eye icon on the map until the system has their own position.
