I assume you have two networks at different locations and wish to bridge them?

If that is the case you will need an accesspoint cabable of acting in that capacity.  Cisco gear will do it, so will symbol.  If you want to go low-end Dlink makes a cheap acces point that can act as a bridge ora  repeater to extend wireless coverage.  If you are trying to cover any sort of range over 300 yards you will need an external antenna better than whaterver one came with the access point.

Typicly a yagi will do, you can get them on ebay cheap, or you may even want a parabolic dish if you realyl want to cover some distance.  A dish can shoot a wifi signal a good mile, provided you have a clear line of sight and no obstructing mediums.  Thing like cardboard, drywall, and metal really eat up signal.  So don't try to plow your signal through 3 buildings, it just wont work well.

You can get 2 cheap little linksys AP's to do the job, as long as you get a good antenna on both sides.  Check out ebay for 802.11 antennas, you will be suprised.

cisco aironet 350 (NIC) gets very good range with an outdoor antenna but I forget if it can do 3km.

I am going for linksys Wireless-G WAP54G Access Point Hub, 802.11g Price: $99.99 , and  2.4Ghz 24dBi Parabolic Antenna System Price: $67.95.

But i don't know about cables , i have measured one side will have 15 meters and the other side 26 meters i don't know if that length is ok or not or the signal will be weak. what is the maximum length of the wireless cables.

...So netstumbler.org is a multi-purpose forum it's not just for the things that aren't supposed to be posted here.  I posted something about downloading something thru a p2p network (which I should not've posted) but this post is different because netstumlber.org actually does have a forum just for building antennas!!!
