outdoor Wireless-indoor access

[afshin]

Dear Helpers,
I want to know if there is a solution for wireless
Network in a 2 KM circle?
In Other words I want to if the Below Situation would
work or not:
Installing an Access Point 802.11b with an omni
anthena in  20 Meter high from the earth.
and then I want to know can an indoor wireless LAN
card 802.11b can access the AP or not.

Thank you in advance,
AFShin (AAS)
