If it is clear LOS (Line of sight) it is said to go a TOP of roughly 10 miles, But that is in the best of conditions, expect more like 2-3 miles (Remember LOS). I plan to have exactly the same setup running (VERY) shortly, except im using a RB 112... I will let you know how far I can get when I get there. Good luckWith RB532 and SR2 card, Data rate 1MB 802.11b multipoint AP (15.4 Omni antenna), how far it can go ?
