The trees are all pretty close to each other, about 3-4 city block radius (map of trees [1]). The issue is that as far as I can tell there is no existing LoraWAN gateway on The Things Network I can tap into [2], which means I will have to setup my own gateway. Which is fine, but it may prove to be difficult to get this onto a tall building since I am just an apartment dweller. At the very least I can put the gateway in my apartment window.
