What outdoor access point with range

A friend of mine asked if I could help setup an outdoor access point at his business to allow three or four laptops to connect to his LAN. He has a small warehouse and the signal will need to be strong and reliable for about 150 yards away. I haven't ventured off much from the basic Best Buy Linksys and like but I would like to help him out.

I was advised about the Cisco Aironet 1300 but I'm not sure of how complicated it would be to setup or if it's just overkill. I've also seen a couple of APs at radiolabs that might do the trick but I thought I would do additional research. The three concerns are range, security and reliability as the clients will be logging into a small database. He's willing to pay for better hardware that will last through his growth and is reliable as he has no real internal IT. Any advice would be greatly appreciated.

Are the laptops all in one direction or a central location?

You would want an AP with a high amount of mW, especially if its all going to stay inside (antenna and all). It would really depend on how much interference you have between the AP and the laptops (trees, other wireless devices, thick/metal walls, etc). Those factors alone will determine wither you need to go with something like I listed below, or a simple, everyday router.


A high powered AP for larger coverage and for wireless dense areas: 802.11a/b/g ENGENIUS ECB-8610S 600mW WIRELESS AP / BRIDGE

An every day, basic, consumer based router: http://www.linksys.com/servlet/Satel...=4329833028B07

The Linksys would work well, again, depending on your environmental factors. There are also 3rd party firmware which you can update this router with, which will unlock other features. One of which could be range extending (higher mW) controls, depending on the firmware.

A good Outside mounted antenna for the router would be the best place to start.

you would be better off using the outdoor version of the ecb-8610s the
