Gas Plasma Antennas Help Wi-Fi Security

mindless4210 writes "Markland Technologies has developed a new gas plasma antenna technology which could help to secure wireless networks. The technology allows for highly directive and electronically steerable digital data transmission via solid-state semi conductor based plasma generators. A plasma antenna can reposition itself at very high speeds, as well as change it's beamwidth and bandwidth, creating spatial and spectral security features which are not presently available with conventional WiFi antenna technology."

Lamest security claim of the century?

What good is a directional beam if it hits some radio-reflective object and bounces somewhere else? Also, even if the beam is 99% directional, sensitive or very close receivers could still pick up the 1% that leaks. A security system that is 99% effective is not much better than a system which is 10% effective. Without solid encryption and authentication built-in to the protocol, directional broadcasting is useless. With solid encryption and authentication built-in to the protocol, directional broadcasting doesn't add anything.

The one place where this could have some good security uses is for undetectable transmission, which is probably interesting to the military.

Of course, directional broadcasting has a whole set of real benefits, such as getting more bandwidth by allowing more transmitters in the same region, minimizing interference, minimizing radiation output, etc. But to call this a security feature? I guess the "everything good is a security feature" is the parallel to "everything bad is terrorist" idea which seems popular lately.
