Linksys makes external N antennas HGA9N.
The access piont can be sealed in NEMA rated weatherproof enclosure with a weatherproof bulhead N connector going to the antenna, and using PoE, the ethernet line can enter the box using a weatherproof rj-45 jack connector. The box and antenna can be mounted on a high structure such as the side/top of a building, or on any other high structure. one device might do the job, but 2 or 3 devices spaced evenly probally would provide the best, most reliable connection. As for security select devices that can use WPA2 encyption. A RADIUS server (ex. Windows server 2003) is needed for the highest level of this method, but a preshared key method can be used. the advantage of using the server method is that you can selectily control what users can use the wireless access and at what times, and for how long.
