The Mission: In a mesh network, every device repeats signals. However, a "Repeater" is a dedicated node placed permanently in a strategic location (High Altitude) to bridge gaps between users. It is the lighthouse of your network.
Choosing the wrong board for a solar repeater is the most common mistake. Efficiency is everything.
Great for handhelds, terrible for mountains. They burn too much power just listening.
The industry standard for permanent infrastructure. Modular and ultra-efficient.
You must configure the device role in the Meshtastic App. This tells the node how to behave.
The node tries to sleep as much as possible to save power, but wakes up instantly to repeat packets. It appears on the map.
"Stealth Mode." It repeats packets but mostly hides its own existence from the node list to reduce network clutter. Good for very congested cities.
Acts like a Router but manages Bluetooth connection better. Use this if you plan to visit the repeater often to check logs with your phone.
A repeater on a 100ft hill covers 10x more area than a repeater on a 10ft roof. Prioritize elevation over everything else.
Stock antennas are 2dBi. Upgrading to a 5.8dBi or 8dBi Fiberglass antenna effectively doubles your range without using extra battery power.
How long will your node survive if the sun disappears for a week?
*Calculation assumes average idle current drain. RAK (~5mA), Heltec (~110mA).
