Long Range WiFi

Back in 2005, Team iFiber Redwire “shattered their previous world record of 55.1 miles, and the ground-to-ground amplified record of 82 miles set in Utah. Team iFiber Redwire achieved an unamplified, 124.9-mile, 11-Mbit connection for 3 hours.”

Huge Antennas

One of the biggest myths related to wireless LAN security is that placing an access point in the middle of a building or turning the power down will increase security. The assumption is that the signal will be too weak for anyone outside the building to detect.

This may be true for wireless cards with internal antennas, but any serious attacker will utilize high gain antennas to amplify weak signals. With a large enough antenna, any network is within reach.

Hacker’s Favorite Tool

Most hackers wouldn’t try to access a network that is miles away, but the fact that they could should be a concern. Access from hundreds of yards away is more likely, and is pretty easy with high gain antennas that are very portable and cost less than $50.
