Extending the range of a wireless LAN

Hi Group, I am looking into extending the range of a wireless LAN setup - I would like to reach a target approximately 400 meters away. I could setup external antenna/s on the source but the receiver will only be a laptop with no access or provision for external antenna's.

Has anyone had experience in overcoming this sort of problem?

No experience, just aware of the following from lunch break chat. Free net access via maccas?

Would a passive repeater work?

You need an external antenna , if it has a nic then apply a suitable router/ap mounted in a water proof box under the external and cat back to the lappy ( although you might detect the wireless in the house it is unlikely) email me if you want more information ,

is it 400m in the clear line of sight ? ( or it wont work)

Only? :-)

Hope you have an USB port .. :-)

Sure! :-) here is a repost ... from sci.electronics.design ============================================

get the cheapest Usb one like Canyon CN-WF518 for 20$ :-)

set to 802.11b Only mode!

USB one (easier to implement "enhancing") ... & do some enhancing with it ... Buy cookies in a reusable tin box! For few km links :-) ... see some mine experiments & data (measures etc) ... text you won´t understand (sorry still not translated in english for my site, planning to do it in few months when having time to spare ..) ´cause its in my native one -slovene ... check fotos: SpajkyTenna®s :-))

Yep

1) It MUST BE be clear line of sight. Anything in between (walls, glass, etc can stop it working.

2) If that doesn't work, then you need an NIC that will take an external aerial, which you install with clear line of sight.

3) If that doesn't work, then you needs a focused external aerial (about $300 each) and clear line of sight.

4) If that doesn't work, then something ic fscked.

Theoretically, you can stand 400 metres away across a cleared paddock and depending on the nics, they should connect. Sometimes you might need to stand on a tall ladder at each end.

Generally, the internal aerials are crud for distance. They are really only designed for a WAP in the top corner of a room.

Suitable aerials are available for less if you know where , I would suggest most situations are covered by the home made bi-quad antenna

agreed

Agreed, but I expect OP isn't looking for a home made solution, thus he could be pleasently surprised when he found a cheaper commercial aerial, That was actually an old price on a high gain directional from Rojone.

Considering that peeps have 8kms (hill top to hill top) on pringles can, but that was fiddlers and sadly they only used netstumbler and didn't test through put.

COmpnay based in WA with outlets in most states has a suitable for around $160.00 plus mount

It's easy to achieve with the right equipment .

that was basically what we were demonstrating. so long as you ave good line of sight, no problems.

Sadly I'm in a valley and were did all these trees come from {:-)

and line of sight

Hi atec77, what are you using at each end and for the aerials and what speed can you maintain?

The devices are commercial 21 db devices (aerials) and it's fast enough to do whats needed so better than I expected ( unless it rains) also a fair bit of heliax and some range boosters :)

Thanks to all the useful posts, I will continue my research on antenna's etc.

Yes I did leave out the vital "line of sight" situation that I need to over come, with increasing the height of the "base" I should be ok.

Once again thanks for all who have given me some more directions to take.
