I know. But our LoRa-Modules have very good RF-Parts (~150 db).
More gain? I mean every FullGW should be recieve every message from the nodes in his reachingarea from every position (horiz/vert/diag).
More gain. Hmmmm… In some cases it would be an good solution. But in my opinion i am not that meaning. Why?
Have a closer look at an omni antenna with 0 dBi
That antenna recieves all transmissions from every side like an globe.
Antennas with higher gain concentratet there energy in one direktion
But now, what is with the nodes under ore over the antenna???
Some datas for dBi vs aperture
Omni with 12 dBi Gain has an aperture about 7° degrees
Omni with 15 dBi … 3,5°
Omni with 18 dBi … 1.8°
When the nodes are all in the same line and hight, cool. But when not???
Ergo. We need more GWs with antennas that transcieves like globes to cover the areas.
