As per @Squozen's advice; outdoor links are potentially very complicated to design with lots of not-obvious considerations to take.
Ruckus have EOS'd the P300 point-to-point/multipoint bridge solution but there may be some left in your geo, so it's worth asking around.
Alternatively, consider the new T350se access point, with the new 30x30, 2-stream MIMO directional antenna and utilising Ruckus SmartMesh with Cloud, Unleashed or SmartZone as the controller to enable the SmartMesh functionality. It should be noted that this isn't the intended use for SmartMesh but there's no reason why it shouldn't work well over 1Km with unobstructed LoS and Fresnel Zone.

I hope that helps,
