wifi antenna with wifi AC?

I am a college student who is moving off campus and was trying to amplify the wifi signal to my house which is 530 feet away from the on campus apartments, which provide wireless internet. there are trees that obstruct the line of sight, but no buildings

I found plans to build an antenna here and fix it on the roof

http://www.engadget.com/2005/11/15/how-to-build-a-...

i plan on connecting it to this access point (which will be sitting in a vented tupperware box next to the antenna (so it will be waterproof, not a problem), and then connecting a second AC using an ethernet cable which will be in the house so we can get better signal inside without loosing gain by having a long antenna wire.

http://www.newegg.com/Product/Product.aspx?Item=N8...

the question I had was: will we be able to get signal from one of the cisco access points inside the building to the antenna, and through the 2 other access points? right now, in order to connect my laptop to the school wireless internet, I have to open a web browser and log in using

the student account.

    That is not going to work. I have never seen an omnidirectal wireless internet connecton that will work like.

    I have seen some that could do, they may be more difficult to install and uses a satellite-like wireless receiver. Chances are that it need to line of sight and those trees might pose a problem.

    There is a way to build an antenna out of a coffee can. I have used these a couple times and the range boost if phenomenal. There are nothing more than what you would use for a feed on a parabolic dish, which the feed has considerable gain in it's own right.

    I have gotten a range of nearly 1/4 mile (1320ft) using this antenna design. If you have a clear shot out of a window there should be no problem.

    I have also used these for amateur radio at frequencies higher than 2.4gHz, on paths longer than 10 miles, so I know that they work.

    Yes and no. You have to have the correct equipment. I have a Linksys WAP54G which I re-flashed with firmware from dd-wrt.com. The new firmware allows me to connect to other access points as a client, should I so choose, it will then allow me to bridge this connection and share the network I'm connected to inside my house. Two main reasons I would not attempt this. 530 feet is a pretty long shot for reliable wireless, and the trees WILL affect your signal. Secondly, wireless is really a pain in the rear to deal with, and it's not worth the fight most of the time to not just order internet and find someone to split the cost with. One last thing, if you didn't understand what I was talking about earlier (re-flashing the router's firmware) then don't attempt to do it! Just recognize this project as a little out of your league and give it up. No shame in that. Save the money for your internet bill :)

    What is this AC you speak of? Do you mean AP?

    This will not work. Your house might (I stress *might*) be able to pick up a stray signal from the APs on campus, but there is no way the APs on campus will hear the return signal from your house.

    The only way to make this work is to use specialized wifi transceivers that have the balls to throw a signal that far. We're talking expensive, proprietary equipment. Connecting at that distance requires technology outside of the 802.11 "wifi" standard.

    The 802.11 standards were designed for close-range connectivity. There's no way to use consumer equipment for long range connectivity unless you use huge dish reflectors, some super-accurate positioning, and some serious noise filtering.

    Also, the APs at school have their radios intentionally powered low to prevent off-premises access. They only want coverage where it's needed. Campuses use a large number of low-power APs to control coverage. A typical household uses a small number of full-power APs (usually one) for maximum coverage.

    If you did have line-of-sight, one possible solution would be to build and use RONJA transceivers. These use a visible beam of light to establish a 10Mbps full-duplex connection up to 1.4km (0.8 mi) away. It's built at home using typical red LEDs, and the plans are freely available here: http://ronja.twibright.com/

    Maybe you can make friends with someone that lives in an apartment with line-of-sight to your house?

    My suggestion you don't have to provide any access point just use 2 wireless device like cisco, linksys.

    Use the outdoor grid antenna with big power 24dB on your campus apartment and your home, and set your wi-fi with point to point setting.

    Use the same brand wi-fi.

    The two use completely different radio bands and are of different technologies all together. They would not cause interference.
