Wireless Over Distance
Hello All
Have a Good Mate who have Broadband in his Business in town.
At his home which is 8 KM as the crow flys he does not have access to adsl and next G isn't a great option with 3 teenagers in the house.
Would like to know if possible we can share his internet connection from his Shed at work On edge of town to his Home out of town threw a wireless Connection.
Line of Sight has some trees, Minimal Houses and shed ( Possible a fruit packing shed or 2 )
I have heard about people getting long range connections using Sat dishes and specialized antennas etc.
Can this be done at a reasonable cost.
He has A WAG54G ADSL modem from memory which has wireless working ok within the Business. ( What other hardware should we acquire )
the way I see it if we can get a setup that works say double that distance then 8kms should work very well...

Have been told of a few looking into this for longer distance wireless.
have looked at this in the past
kits are about $1000 and you need clear los
i have to many trees
If you no what you are doing this is the best and most cost afective way , i have 35 km links working at great speeds ,
verry cool stuff and cheep but with all this type of thing you need clear los
As REG said above Line Of Sight is the up most importance especially if it's 8k's away
What about his neighbors maybe he could swing something with some one a bit closer
When you do things right, people won't be sure that you have done anything at all
His house is out of town surrounded but many large paddocks. His business is pretty much on edge of town. Had a look at google maps and it dont look to bad. downloading google earth at the moment to see if I can draw a line from a to b to get a better idea of whats in the way.
Found to be very interesting... and also

Just used Google Earth Ruler and over the 8 KMS amazingly found to be approx 8 large trees and 1 house in line of sight. There is an orchard in between but we plan on putting antennas on roof of shed and house well above fruit treee height.. and also above house height...
The road he Lives on has Crap phone Lines, he is on a pair gain line and a noisy one at that.Originally Posted by best4less

The closest ADSL is approx 5 kms down road
Would rather use his own connection than to use someone elses
but its a good idea just the same
Just one thing with the link you posted you wont get anywere neer what your after with a omni antenna.
I have a friend running units sold by Hills with a fly swat at each end and he gets a good connection over around 5 Km perhaps more. Its clear line of sight too.
From memory the Hills units where around $600 each plus $160 per fly swat but that was 5 years ago now.
A friend has just tested a 2.4 GHz link over a distance of 25 km and no issues at all. Using a couple of 19 dBi grid antennas, and at the TX end (it was a one-way link) he had a 1 watt amp module driving into the antenna. A little bit on the *not legal* side - do the maths with 1 watt and 19 dbi
but it worked well, and he could probably get away with less power into the antenna.
It was LOS however, from on top of a hill range down into a town area.
Awesome. a one way link would be fine, Line of sight provided we get it up above roof line shouldn't be to bad.A friend has just tested a 2.4 GHz link over a distance of 25 km and no issues at all.

What other equipment was he using...
Wireless networking is definitely not limited to short-distance communications within a single building.
Wireless network links are quite common these days with many businesses, medical practices, etc. maintaining wireless links between nearby premises and often across suburbs spanning several kilometres or more. Traffic lights located at many suburban road junctions utilize wireless network technology to ensure synchronisation with traffic lights at other nearby intersections.
Community groups have also established wireless networks in various cities in Australia and their websites are a very useful repository of helpful and practical information for you to use in your own experiments.
Melbourne Wireless and Air-Stream are two such groups in Australia.
Seattle Wireless at is one of many other websites where you can obtain much valuable information and "How-to-do-it" articles to enable you to establish your own wireless network link over distance.
Silicon Chip Magazine has published an article, The Art Of Long-Distance WiFi, part of which can be viewed at
Incidentally, links are not limited merely to several kilometres, but have been established over hundreds of kilometres as reported in many places, including , and . Such large distance links utilize very heavily modified equipment and large antenna systems.
The link provided by REG in post 4 (above) is a very good site to visit as the information located there refers to the use of locally available wifi units.
The Linksys WAP54G Wireless Access Point and similar Minitar units are very popular for the purpose Mutanti outlines, as they are easily modified for higher RF output as described at and others.
The WAP54G is readily available on eBay at reasonable cost and high-gain antennae are easily made by the home constructor as outlined at and similar sites.
There are articles on the www describing how to modify the high-gain ex Galaxy MDDS antennae for 2.4 GHz wi-fi use.
Do a Google for additional information.

Just set up a 19.2Km link @11 Mbit/s today using an old MMDS PayTV dish and a Asus WL500G AP.
I think you will find that one way links wont work as there needs to be a two way association and most protocols require acknowledgement of data transfer.
Good Point...
Ive contacted freenet
Will see what the reply is.
IE3 x 2 systems might be the go..
The system he was testing was effectively a long distance audio link.
The TX end has a digital audio sender fed into the 1 watt amplifier which was modified to handle CW, then fed into a 19 dBi grid antenna.
The RX end was just the receiver part of the digital audio sender system and a 19 dBi grid antenna. That was it. Nothing else.
Correct!, e.g tcp/ip
You can use wifi for download then land line dial up modem for upload of data confirmation (tcp handshaking ) same as satellite
Cheap STL?
