A:Answer Hi Dbasu,
If mounted on a pole 20 -30 feet off the ground outdoors in an open field, This would have a HUGE WIFI signal footprint. But assuming that you'll use this INDOORS, there are too many variables in each situation to give a straight answer,
The walls, floors, and ceilings in a home or business, plus their composition and internals -wires, pipes, etc.-can have huge effect on WIFI signals.
In my situation I use this product where it must grab a router signal passing through 3 walls, and send it along through 2 more into my workshop and back again, which it does flawlessly. I now have as good WIFI in my semi-detached shop at the rear of the house as in the living room or den.
Remember, if it doesn't work in your situation, they'll accept a return.
Hope this helps your decision. ~ VOR
