Wi-Spy Comparison

There are significant differences between the original Wi-Spy and the Wi-Spy 2.4x. Most importantly, the quality and accuracy of the graph displayed by the 2.4x has vastly improved from its predecessor. Please take note of the improvements on this 802.11g spectrum scan.

"So which one to buy? If you're just doing the occasional spectrum sweep, or just curious about the 2.4 GHz airwaves around you, $200 is probably enough to spend to scratch that itch. But wireless installers on a budget and other folks who charge for their services would be better off spending the extra $200 for the extra range and, more importantly, frequency resolution of the 2.4x. As the earlier screenshots show, the difference is both clear and provides value. And don't forget the ability to attach directional antennas!" (Tim Higgins, SmallNetBuilder.com)
