Networking within 3 kilometers

hi guys, i dont know if this question even makes sense, here goes... is it possible to network wirelessly two computers 3 kilometers away from each other? i have a DSL line at home and i want to share it to our office maybe 3 kilometers away. am paying a lot for the DSL line, but the thing is, i cannot afford another line in the office because DSL subscription here in the philippines is quite expensive especially for commercial use. iv heard about powerline networking, 802 a/b/g, but i dont know if any of these standards is capable of 3 kilometers range even with the help of a bigger antenna. any tips on how to do it and the things i need is very much appreciated... thanks. i dont need 54mbps speed, my DSL line is just 256kbps, so a speed of 1mbps would be very acceptable already. by the way there are lots of houses along the way.

  2. 802.11b is capable of reaching 12 klm. or so.

    But you must have a 19dbi to 25dbi dirrectional antenna and line of sight.Meaning that the antennawill need to be mounted on rooftops or a mast to achieve line of sight.

    I aint signing nothing!!!
  3. can it not work like a walkie talkie radio? coz we have a wireless antenna at home and it can reach our office even though without line of sight
