Hi, been looking at P2P bridging for internet access to a external building, few 100 meters of distance. Came across the CPE210, but wondering is there a minimum distance that the like would be effective. My understanding suggests they are designed for bridging distances in the Kilometre range (5km + I believe they are intended). Would it still work in this relatively short distance? 
 

Any other factors to consider at this short distance?
 

Any other products to consider?
