View Full Version : Wireless LAN

12-01-2005, 04:24 PM
Hello to everyone

I am interested on installing a wireless LAN (compatible for broadband)between my neighbour and me with an areal distance of 400 lineal meters. There are only a few landscaping trees in between that hinder the direct sight.
Does someone know the ins and outs to do this and which machine would be suitable.

A reply is very much appreciated

Two wireless lan cards in two different computers,one at your place and one at your mates, and a chainsaw to chop down the tree.

It sounds possible, I know up to 30Km has been achieved using special antenna's, obviously not at a quick connection speed.

After a quick look on the net this seems to be about the average speed to distance ratio for 802.11B

Max Distance of 11Mbps: 100m
Max Distance of 5.5Mbps: 200m
Max Distance of 2Mbps: 300m
Max Distance of 1Mbps: 400m

Obviously some will be better than others and there may even be some routers specifically designed for longer distances.

Hope this helps...

With home made Cantenna's or dish areials, which cost around $10 to make each, the range is in Kms for line of sight.
If you do not have line of sight you could be wasting you money and time.

If you've got money to burn, take a look at Belkin's Pre-N wireless networking equipment (http://catalog.belkin.com/IWCatSectionView.process?IWAction=Load&Merchant_Id=&Section_Id=202625). It's designed to give greater distance and speeds, but at the moment they only have a router and a laptop card available.

I'm not sure if you can use normal 802.11a/b/g equipment with the Pre-N technology, but I think you can.

However, you should note two things that have been said - trees play hell with wireless networking, and you can make your own aerials to cover extended distances very cheaply.

Thanks so far guys.
Let's see what more is to come.
Is it really that a few leafs can make such a difference? I can understand if it is a wall or any solid barrier over a certain distance..?

So I'll wait and ..

Go for one of those nicer Linksys routers..... And get a booster arial for it :-) You could easily get a KM or two with a few db difference

Hi Chilling_Silence
Can you explain it a bit more for an half way experinced person!
What machine and whatever als is needed? Any idea of costs?
Gion :confused:

Trees are said to make a huge difference, but in practise I have found them to be nothing more than an annoyance - that being said, the power output of my antenna isn't quite legal. If you can get a decent output card and a good booster aerial you should be fine...

You'll need one AP (Access Point) and a compatible protocol adapter for your neighbour at the other end.

Costs? About $200 - $250ish....
Something like:

Great quality AP!

Then you'll be after something like:
Or maybe something even more powerful :)

This may be of interest as to what db rating give roughly what range:

I use the D- Link DSL604+ 22mbps wireles router and built in modem and D- Link DWL - 520+ on the networked machines.

The DSL604+ also has 4 ethernet ports for LAN as well has the capablities of WLAN.

Also look for G+ or G plus or G max from different manafactures as these will double the 54mb speed of the standard G. I use D-Link.
Pick a couple of modles that fit your budjet and come back here to weed the best one out.

Thanks guys,
so to summ up (taking into accopunt that I have to machines that I Like to have on my network, which I have laid the cable)

Getting a router
with modem ?
with the above specs
a cable from the router to the areal
buy or make an areal for both sides
connect all
hold my breath and hope?

Does that sound ok?

How do you connect to the internet at the moment?

Are you going to share the internet or just files?

Gion - do you live in Christchurch? If so, there is a ChCh Wireless Community here that may be able to assist.

You only need one AP and one Booster Antennae because yours will have the range to send/receive over to your neighbours place, even thou they're only using some stock standard 802.11g or even b adaptor.

Good morning to you all
Firstly thanks for all the answers ;
To the area; I live rural in the Nelson area(trees)
In the next few days I intend to go on the roof and check out exactly if there is straight sight or are those trees in the way.
Does anyone know if I could use an old SKY dish as receiver on my end?
And is there somewhere a "manual" how to do the setup step by step?

Yes you can use your Sky dish, you still need to make a cantenna to fit to it tho.

16-01-2005, 02:20 PM
see usbwifi.orcon.net.nz as Im pretty sure somebody there used an old Sky Dish.

I was going to be contacting Sky myself to see if they'd sell me an old 2nd hand one cheap :D

16-01-2005, 06:24 PM
ive got a old sky dish, i was always interested if i could use it for wireless networking, but still dont know how, its not for sale though :p

you could check out trademe, they have sometimes have one there

Thanks John and also all the others for your help.
The links are good!!
I feel that with my neighbour together I can takle this project. Still I need to look at the costing and that will take me a little while.
Once more thanks to you guys!!
