Ok that is what iheard and i want your opinion or if you know how i can do that....i heard that one student has a dsl connection and his friends that live in a distance >5 km and have visual contact with him have satellite dishes and are also provided with the same connection somehow through the dishes....in fact i heard that from another student...can that happen? If yes could you tell me some details? Seems interesting :)
I don't understand what you are asking. If John has DSL and Mike and Derek live two houses over, if he has a strong enough Access Point he can share via Wireless. However, if John has DSL and Mike & Derek have Sat Dishes there is no way they can pick up the DSL signal because it comes through the RJ11 (phone line).
Probably whats happening is the person who has the DSL feed, somehow has it set up so he can transmith the signal over the satelite dish to his two friends via their satellite. Kinda like wireless internet.
I can't tell you how he did it as I've never done it, but I'm sure thats possible to do.
Can be done and is being done, right here to write this reply :)
Quite simple .... I simply set up an wireless Access Point at my sisters house which feed to a directional antenna (sat dish or similar - plenty to choose from) then set up a converted sat dish at my end which feeds down to another wireless Access Point (running in client mode) that feeds my network and presto - full 1.5/256 connection in an area that can not receive DSL due to normal telephone line restrictions (distance from exchange).
I can stream movies, mp3 etc .. from her network straight onto my machine and visa-versa and running 802.11g we generally get a 1.5-2mb/sec connection between the systems. This figure can vary vastly depending on distance, interference etc between your two systems. We are about 1km apart and have good Line of Sight.
A little knowledge on networking helps.
If your really interested may I suggest you search for a local Wireless Users Group near you, there are many out there and they should be able to point you in the right direction, pardon the pun.
Word of caution, some of the gear is not cheap and not always compatible to what you want to set up - so if you are serious, a moments research will save you hours of frustration and save you money.
Also check with the Terms and Conditions of the ISP supplying the DSL feed, if the client is on-selling the service it could be seen as a breach, even the broadcasting of the service outside the supplied address can enter the "grey" area. Some ISP's might get a bit funny about you "giving away" a service they should be getting money for. A quick "anonymous" call to them should let you know what their feeling about the matter are. I did it and was open with them and their people gave me their blessing and wished me luck - but as said, I am outside their service area so things might have been different if they could have supplied DSL at my home through normal channels.
Then there is the Communications laws in your area that need looking at - as you will be running a "radio transmitter" there are restrictions on how much power you can pump out, requirement for a carriers licences (maybe) etc ... but most standard wireless gear can do a 5km link running on standard as long as you have good Line of Sight between the stations.
Have fun, and stay in touch with the security issues with wireless networking, unlike the wired network, any Tom, Dick or Harry with a laptop and wireless card can prop and steal your bandwidth (or worse) if you dont lock things down properly.
Its a good hobby and there are tons of resources on the web to keep you busy for the time being.
PP.
Ok i guess i will now have to read a little bit..any good reading suggested? And i dont think there is a local wireles users group nearby..anyway i live in greece in athens...thanks a lot...right now it is 5 ;ocal time and i am a bit drunk as i just returned from a party so i did not understand everything you said :) I ll look also tomorrow...
Just did a quick search with my friend google and turned up a few things that may help ......
