Dual Antenna AP + Mesh Parabolic + Omni, serve as NODE?

Hi there, I’ve got a few questions, hopefully they wont come across as being two basic. I’m studying electrometrical engineering at Southampton University in the UK, (this part is irrelevant). The university runs a wireless network for students to connect from nearby houses and student-halls. There are 5 nodes at present.

From September I will be moving outside campus and would still like to have access to the wireless network. Its 2.6KM LOS, which has been tested, from my new house. I would like to set up a node to serve other student in this area.

My question is basically, using a Wireless Access point with 2 antenna sockets (haven’t got one in mind at the moment), is it possible to use a parabolic mesh antenna (because of their cheapness and high gain) to gain a link to the university, then by using the second aerial port to re transmit the signal via an omni. So bascially setting up a node

I’ve got my doubts, so maybe two access ports might be needed for this configuration.

Here is a link to my local, and cheapest supplier:

Any help would ge great.

No, you will need 2 APs, or else a dual radio AP, but those are silly money, so go with 2 normal accesspoints.

If you have the local accesspoint (away from the uni) on the same SSID as the ones at the uni, you will need to get a client mode accesspoint that will allow you to specify the mac address it connects to, the older dlink 2000 firmware did this, and it was good because it meant that it would always client off the accesspoint that you chose, whereas the newer firmwares use teh SSID and find the mac address, and when I tried it would always end up clienting to the AP sitting beside it so not do anything usefull other then sit there repeating packets back to itself.
