    Hello all ..:)

    I finally bought a WRT54G wireless router ..the one with no antennas at all .. but it has an input for a linksys antenna (i dont have it) .. i use the router for internat sharing ..

    It works fine .. :thumbup:

    now i want to add a link with a neighbor, he is about 50 meters away .. and there's a tall fat building between us ! ..NLOS :mad:

    How can the mission be done ?

    What antenna do i need for my router (if any) ?
    what does my neighbor need to buy exactly to connect to me ?

    This is my first post .. im still a newbie in this field ..

    pls help :biggrin:

    Thanks in advance,

    You're asking a bit like "how long is a piece of string". Buildings can have a major influence or very litte influence on signal getting through - it usually eats signal like crazy.

    In terms of what antenna you need - can't help you directly, but if you are in the ETSI region, where 100mW or 20dB is the maximum power you can beam, and your WRT is running at 28mW, it leaves you with a maximum about a 6dBi antenna that you can use.

    If you want to project your signal in a specific direction, you need to get a directional antenna like a Yagi, patch, or waveguide type antenna.

    If your neighbor gets exactly the same setup that you have, you might or might not be able to connect to each other. You'll have to test - as mentioned, the "big fat" building's influence can not really be predicted.
