Visualization Tools: Everything You Need
The visualization techniques used in WiPry-Spectrum give you the ability to see your wireless network from a variety of different perspectives. Some prefer the real wave view (top left), and some prefer waterfall mode (top right). Regardless of your preference, we have all the tools that you need to identify and avoid interference.
Identify and Avoid Interference By Changing Channels
The 2.4GHz band is a busy place. Your wireless internet operates in this range, as well as other electronic devices such as baby monitors, cordless phones, garage door openers, and microwave ovens. Since WiFi can extend as far as a football field, nearby buildings or residences can also cause interference. This activity is organized into channels. WiPry-Spectrum allows you to see exactly where noise is coming from along the ‘spectrum’ so that you know which channels to avoid. In the example above, you would avoid channel 3 (along with any overlapping channels) because it has the most noise. Then, you would select channel 10 (or another channel without interference). Now you can answer the question: which channel should my wireless network use?

WiPry-Spectrum will allow you to view which frequencies in the spectrum are already in use or have a high noise floor. Selecting a channel with a low reading will yield increased throughput and lower latency.
For specific frequency measurements, you can use the cursors or the divisions on the screen. To view WiFi channels, click on the plus sign in the top left corner. Then, tap on any of the channel numbers listed. It is also possible to enable specific WiFi guides such as 802.11b, 802.11g, 802.11n -20MHz (2.4GHz only). To change the channel map, go to the menu bar and tap Measure. The option at the bottom of the menu is WiFi guide. This will enable you to manually select a guide. The default is 802.11n - 20MHz.
Yes. Touch and hold the pause / play menu icon and it will change into single shot mode. After the mode has been changed, tap the single shot icon and the next event will be captured and held. To go back to pause / play mode, touch and hold the single shot icon.
20dBm is the max. If you need to make higher power measurements, please make sure that you use external attenuation to bring the power level below 20dBm.
If you're using an iPhone / iPod touch, you can use WiPry-Spectrum continuously for approximately five hours. If you're using an iPad, you can use WiPry-Spectrum continuously for approximately eight hours.
Please understand that these estimates are just that, estimates. Your results may vary based on your background usage level (WiFi, email push, other apps, etc).
