I use a "home brew" version of the Wi-Fi Ranger. From what I'm told the outdoor module is the same one they use with a different name on the box.
How it works?
Well. note that I might not have chosen the best outdoor module but it gives me RANGE more than anything else.. IF the signal is week inside it MAY increase throughput or not depending on many factors
Example.. one park I frequent the Wi-Fi is all but useless. Even sitting on the router (Within sight of it, direct line of site Same room) there are so many users DSL is faster.
On the other hand if it's not that crowded.. then if I've got a "Weak" signal on my laptop I can fire up my "Ranger" and the throughput goes up... WHY>
Each packet contains some self-check bits. if the packet fails the test then the computer asks for a repeat ... The weaker the signal.. the more repeats.
Home was where I park it. but alas the.
