Honestly, its a fun side project, but without enough nodes its more of a hobby. If you want to make it usable, its probably better to use internet or higher power devices (like ham). Or buy a metric ton of these and throw them up high.
As long as you have a node in sight, it should be good for at least some communication. My little window node gets 20+ nodes.
