Connecting Two Networks Together Wirelessly

Hi There.

I want to be able to connect two seperate LANS together with a wireless point-to-point link. The problem is that these two LANS are in different building that are about 300 feet away from each other. There are no obstructions between the two buildings, so I believe I should be able to make a point to point connection.

For throughput and security reasons, I want a strong directed signal, rather than using a standard access point with an omni-directional signal.

What is the best product to use for my purpose? I'm sure there must be some Cisco wireless bridges or something that can do the trick.

I want to purchase two such devices, each of which will reside indoors in each of the two buildings in order to establish a point-to-point link. There is a double-pane glass window in each of the two buildings, so I'm hoping the wireless signal will have no problems passing through that.

In addition, I have indoor 802.11g LANS running in both buildings. I don't want the external wireless link to affect the performance of the existing indoor wireless LANS.

peace,
 
You will probably need a directional antenna to do this. Unfortunately I don't have any good links so this will bump the thread for JackMDS.
 
For 300 feet with line of sight even the budget SOHO AP's that will bridge will work. If you don't mind spending some money the Cisco BR350 series are the cream of the crop in 802.11b bridging. At that distance a couple of 5-7 dBi narrow beamwidth yagi's will work fine.

As far as your existing WLAN's, you may or may not run into trouble. Depends on how many AP's you have in that environment that would overlaps with your bridging infrastructure. If you only have one or two then just set your AP's and bridge in that particular building to seperate non overlapping channels, 1 6 and/or 11.
 
I am working on a project sounds similar to what you are trying to do. I am using the Cisco 1400 Wireless bridge outdoor ready to make the directional point from one building to the other. Whats cool about this is that you can use WEP and MAC to MAC address providing you more enhanced security. I am also using a Bluesocket which I am going to create a sperate VLAN to that other building and set authentication for whoever wants to use the network.
