New WiFi Scanner Software - inSSIDer
We have stumbled across a new WiFi signal strength software called inSSIDer that seems a good alternative to the tried-and-trusted Netstumbler.
inSSIDer is available for Windows operating systems. It has two main displays open simultaneously.

The spectrum display above shows clearly how WiFi channels are not as separate as you might think. The APs on channels 6 ("Clark") and 11 (BICTON-AP) are quite separate. But the APs on channels 3 ("TestAP") and 6 ("Clark") overlap somewhat. This is not due to faulty equipment - this is the way WiFi works. An 11g AP actually transmits on 5 channels at all times.
"TestAP" is transmitting on channels 1, 2, 3, 4, and 5.
"Clark" is transmitting on channels 4, 5, 6,7, and 8.

The Signal level display above shows a Netstumbler-like plot of signal versus time. |
inSSIDer works great with the Freenet Antennas UltraUSB which can be connected to an external antenna - making a great site-survey tool.
inSSIDer is available from Wi-Spy Australia.

Product Review of the Month
12 dBi Panel Antenna
I use a pair of these with UltraWAP-G's to provide network access 750m across a paddock. There are some trees in the way but the signal seems to find a way through the gaps. I am very happy with the performance. Thanks!
