Hello guys again!
I do understand how meshtastic works, that buildings, trees may cut the signals and the higher the better etc.
Yet, in my home, leaving my device l1 tracker pro at a specific place, gets lots of traffic, and I receive more messages than before. Since then I always leave it there.
Now my question is, how come I can receive messages but not sent, especially when channel utility is 7 or even 10 percent? Do I miss something?
There is likely someone with a higher power repeater (think RAK 1-watt kit) or much higher gain antenna running a node somewhere nearby. With a better transmitter, there is enough wireless link budget to receive such a strong signal at your location, but the puny 25mW@2dBi from your handheld cannot be heard out through the trees and walls.
Look into getting a roof top node set to CLIENT_BASE.
Thanks for your answer! Yea they told me about the client_base, planing to do it in couple months.
Here’s a graph that help explains how LoRa Link Budget works with antennas and transmitters. You can see how a weaker radio might be able to hear a stronger radio in one direction, but the strong can’t hear the weak in the other based off their EIRP.
