802.11a

One other option (for the moment) is to spend a little more money and install 802.11a. While more expensive, it operates in a different frequency, reducing (for the moment) the available hardware that can be used against you. Another possible advantage is the fact that 802.11a has a much shorter range.

Bandwidth of 54Mpbs (up to 75Mbps in some vendors’ unique implementation) is sufficient for real-time video. Encryption in some products goes up to 156bit encryption and the range is considerably shorter in the 5Ghtz spectrum. The same antenna site mentioned above offers 5Ghtz units.

In the real world, changes are happening in Internet Time, so keep your eyes and ears tuned in.
