laptop, pda and mobile phone usually have weak reception and transmit, they have small antennas. Even if you have the most powerful wireless card, and biggest antenna, still the mobile devices will not work further than some 300-400 meters in perfect conditions.

Is the area flat, or is the AP going to be on a hill? How is the visibility to the AP from all area of this 2Km radius? Are there buildings or other obstacles?

with just one tower, at such low height, you will not reach 2km for mobile users.

Like I said, the mobile devices phsically have no ability to send data to such distance. They will "see" the AP, but will not be able to talk to it. They have too small antenna. You need to have a smaller radius (less than 1km) and higher antenna mast. This would mean more antennas/APs per area.

Hi,

Just start with one tower, but know that you wil have to add at least one or two more to become optimal results on al devices.
Hardware? hard to say, how many concurrent users will you approx. have? What's your available bandwidth? Do you think you have enough and accurate network/wireless knowledge to bring this to a good end?
Do you have a radius available for auth en accounting? Thought about billing yet?

Everybody wants to become a wisp, some of them become one, few of them survive :-)
Reading your questions I think you simply don't have enough background to do this.
Hire a consultant or you will probably loose lots of money with zero results.

kind regards,
B

PS Please don't take this wrong, it's good advice.

normally a mobile device can connect some 200-300 meters from the AP

so you would need at least 4 AP devices to cover this area, if you are lucky.

To simplify installation, I suggest using this device as the AP:
http://routerboard.com/GrooveA5Hn

and using a omni antenna with it. as the distance will not be big, the gain doesn't matter so much. 7.5dBi should be enough I think. Maybe somebody else can comment too?
