Wireless 802.11N USB Adapter for long range P2P link

Hi All,

A mate and I are about to test out the following Wireless 802.11N USB adapters in an attempt to create a neighbourhood link that stretches 2kms.

We intend to create an antenna similar to the ones shown at http://www.usbwifi.orconhosting.net.nz/.

We found the cheap adapters at a decent Chinese wholesaler which had them at our doorstep within 3 days for next to nothing! The adapters work fine locally, but the real test will be when they are out on the roof going for the distance using a unidirectional antenna.

They’re obviously not designed for outdoor use, but we’re just going to wrap up the metal parts in tape, and hope for the best. Worst case we’ll be up for another set if it corrodes over time, and might end up trying silicone. For that price, who cares. If it works, we’ll save about $500 each in expensive wireless kit!

Will let you know our progress.
