We have all been wowed by the potential speed and performance of 802.11n indoors.
Q: But how does it perform outdoors
A:Well there are lots of variables here but test have shown the following.
* Distance: 0.95 km ~ 80 Mbps
* Distance: 1.75 km ~ 60 Mbps
Greater then two kilometers nothing? but I imagine that this is a software Mac timing issue, and so a better result could be achieved with directional antenna and software drivers for PCI cards.
Put not bad for a retail hardware hack, trial.
