How strict is line of sight?

Solution 1:

There are equations for figuring out this kind of thing. The tricky thing to find is exactly how opaque whatever kind of leaves those trees have are to 2.4000-2.497GHz radio waves, and how thick they are. The spec-sheet includes the antenna data as well as the transmission power, which are the other things you'll need. Once you have all that, you can figure out expected signal loss over that path.

I am not an RF Engineer, so I don't know those equations. The people who run those FreeNets you find in some cities have spent a lot of time on this kind of question are the kinds of people who'd know this stuff. And, you know, RF Engineers.

My crystal ball says it'll probably work, so long as you get your pointing exactly right. Trying is probably your best bet. If that fails, time to go for the grounded masts to get around/over the trees.

Solution 2:

There are arguments both ways but ultimately there's literally no way of knowing for sure but to try it out. Of course there's going to be a huge difference between summer and winter but worst comes to worst you could always have a small 'accident' with a chainsaw :)(

Solution 3:

I don't think that some trees will cause total lost of connection {I don't know what will happen in the "forest" case :} }

Is there a minimum throughput that you want to achieve ? If not, you could either increase the transmission power {to legal bounds} , decrease the transmission rate by hand in order to have a more "robust" connection.

In any case, i don't think that with your equipment you 'll have problems :>
