Networks wireless signal amplification

hello, now you can't say i didn't warn you because im going to say it now. i am a very BIG amature to the wireless world. i have set up wireless for my dads laptop in the house but im looking to do something bigger. i wanted to send a signal strong enough to shoot it about a mile. i have a simple wireless router and i can adapt it to hook up to a coax cable. now i do know it sends a RF signal at 2.4 GHz like the popular cordless phones. my question is, is there a type of cable amplifier that is relatively inexpensive that i can use to amp the signal to rig it up to an antenna such as the ever so popular "Cantenna". Any advice, links or points to other threads, would be super helpful.

Thanks, Eric

 

If i dont understand wrong, you need, more than a amplifier cable, put your AP on the roof and hook up an cantenna, with this u can handle this distance, with out a problem.

 

ok, sounds good, thank you for the info

 

Just watch out for interference

 

You will also have problems with range if it's not line of sight also, so be sure you have a good clean path without trees preferbly and you being able to see the recieveing ends cantannea.

 

Hi!

Got a simular situation going on here. My brother wanted to be on the internet, but did not have a phone line. He lives about a mile away across my town.

Firstly - Line of sight. Luckly, we're both on the top of a hill - there's about 6 houses between the two antenna, but that didn't cause a problem. If there's a hill in the way or something that solid, unless you can afford a repeater, then you've got a problem.

Next access points. I got hold of two Linksys 54G APs. I know there's lots of people out there with problem with these models, but there is custom firmware (known as mustdie) which allows you to increase output above legal limits of this country (not that I would consider breaking the law).

Then there's the antenna themselves. I got hold of a couple of these...



Then I put them into the attics of both houses (although prepared to mount them outside of the house, this actually wasn't needed).

After about 4 straight hours of making sure they lineup, I get around 6 to 10Mbyte/s through the connection, which is enough for streaming video, internet etc.

I did consider building a form of antenna, but in the end went for a purchased solution to make sure it works.

Also, I was ready to build an in-line amplifier for the system if it had failed, but those are costly.



Good luck!

 

wharrad: Nice antenna's!

 

This one wireless internet service in my neighborhood uses those antennas like that, I use a different one that provides faster speeds and the antennas are quite smaller and seem to work better also.

 

Cheers! Bought them from the net in the end, cost around £50 each for -21Db. It's a touch expensive compared to building stuff yourself, but it came down to being worth it when you know they work!

Yeah, there are a few different types of antenna out there - this being my first real attempt I just stuck with the biggest Db number really! Size is definately something to think about if you keep them out in the wind, 1" movement either way would cause too many problems when on a ladder.
