Wide area wireless

Is it possible to create a wireless access area that cover 4 km range?
How would the setup / configuration be?
The necessary devices?

Would it possible to be a few wireless devices at every 50 meters away
and each connected to each other only through wireless (without cable)?

Thanks.

What wireless protocol are you using? 802.11a/b/g, something else?

Tests have shown that with specialized antennas wireless (802.11) signals can
travel very far. Sounds like you need something like WiMAX (5-8km):

Cisco Aironets can also do the job, as well as other brands I am sure. The
problems you have covering a distance that wide with wireless is other
frequencies you will be crossing over.

You also have to be concerned with security. If it's just a point to point
connection you still have to worry about your traffic being sniffed, etc.
Lots to think about in trying to cover that amount of distance.

Hope this helps,
