I’m trying to make a P2P from my office to my home which is approximately only 7km. The problem is I live in the suburbs and the office is in the city. I’m sure there is no line of sight. Apart from setting the wireless on 30m high, would having the same model help? I’m looking at LHG XL 5 ac on both ends.
Sometimes you can achieve adequate “near line of sight” connections with 2.4GHz, though spectrum is crowded. Better for NLOS is 900MHz, but it is even more crowded. 5GHz and higher, you need true line of sight.
You can use Google Earth’s “viewshed” feature to determine line of sight (modulo buildings and foliage, which it doesn’t take into account). You can set the “altitude” of the waypoints to determine if a reasonable mast extension would make a difference.
