Wi-Spy 2.4 GHz Spectrum Analyzer
August 17, 2007 by Truman
Wi-Spy is the world's smallest 2.4 GHz spectrum analyzer. What does that mean? Well, let's say that your internet reception from your laptop or wifi enabled desktop seems rather slow. Your router is in the other room, or on the other floor. Or, let's say you are installing your router in a new house and are trying to decide where is the best place to put it. Or, maybe you want to see where you would get the best wifi reception on your laptop. All of these tasks are made simple with the Wi-Spy. The truth is, your wifi signal can easily be weakened my everyday non-wifi devices.  Ideally, you should use Wi-Spy if:
- You deploy and maintain wi-fi networks
- Your wi-fi has intermittent bandwidth problems
- The microwave interferes with your wi-fi network
- When the phone rings your network connection drop
When you are deciding which channel to put your wifi on, Wi-Spy is the perfect gadget. It will tell you which channels are the most clear of disturbance, and that way, you can choose a channel that will be fastest for you. This product is designed for troubleshooting any problems with your wifi connection or reception, and also analyzing your connection.
Here are some additional info about the Wi-Spy:
Helps you identify wifi interference
Frequency range is 2.400 - 2.485 GHz
Record/playback data traces
Frequency/amplitude marker
Spectral, Topographic, and Planar Views
-
New Wi-Spy software available here (Windows and Mac OS X)
Linux software download is here
When using the Wi-Spy, which plugs into your usb port, you get an instant view of Amplitude, Frequency and Time, all in Spectrogram Form. This tool also runs on the three main operating systems in use today: Windows, Mac OS X, and Linux. Unfortunatley, this gadget is rather expensive. Now, compared to Other spectrum analyzers, this may seem pretty cheap, but to the average Joe who wants to optimize his network, it's going to cost you. $200. So, if you are a really wealthy person who just feels like constantly making sure their wireless network is ok, then Wi-Spy is for you. But, if you are an independent wireless consultant, home theater installer, or something like that, then you seriously should consider the Wi-Spy.
