Wifi spectrum analyzer mac os x

With WiFi Explorer, you can find the best channel for your network or determine a better placement for your access point. You can also identify channel conflicts, overlapping or configuration issues that may be affecting the connectivity and performance of your wireless network. Expert information, available in WiFi Explorer Pro, such as per-channel beacon overhead, gives you a general overview of the Wi-Fi environment to better plan your network installation or mitigate existing problems.

WiFi Explorer has been developed with the support and feedback of Wi-Fi experts. Its ease of use and advanced features, such as the ability to decode network information, access point name discovery or enhanced filtering, give you a full insight into the capabilities and configuration details of wireless networks. Other advanced features include the ability to find and display information about hidden networks, support for external Wi-Fi adapters, Zigbee integration, and much more.

WiFi Explorer Pro's spectrum analysis integration lets you visualize RF information and correlate it with Wi-Fi data to identify non Compatible spectrum analyzers:. Ready to buy?

Feb 11, Wireless networks are everywhere and we use them everyday. However, there are many factors that influence their performance and getting the most out of them is not an easy task. Mar 23, WiFi Explorer provides an option to display signal strength in dBm or percentage values.

The purpose of this blog is to describe this conversion process in WiFi Explorer. Aug 11, In this blog post, I will briefly talk about how Wi-Fi scanning works, and then I will focus on how this process is accomplished in WiFi Explorer Pro, including the pros and cons of each scan mode.

Documentation

Aug 28, A beacon is a type of management frame in Beacon frames are transmitted by access points to announce the presence of the network to nearby clients and for other important network functions. Rather than examining the scan results in the app itself, you can visualize them in WiFi Explorer Pro 1. If you have any questions or comments please contact me. It provides a color-based visualization of the RF level and activity over time.

As signal levels for specific frequencies or frequency ranges increase and decrease, the waterfall map varies its colors. This feature provides a quick glance back into the sweep history to identify aberrations or fluctuation in frequency levels.

The 'Density Map' chart shows accumulated RF energy as a function of frequency. The power of the signal strength in dBm is shown across the frequency span. A signal strength with a relatively low occurrence is 'blueish' in color, whereas increasingly brighter colors are used for signal strengths that occur more frequently. Signal strengths that occur most often are 'redish' in color. Over time, this spectral view will approximate the steady-state RF energy signature of a given environment.

The 'Delta Trace' view can be used to view small or large changes in the RF spectrum over time. Here's how it works When scanning begins the first trace is saved as a 'snapshot'. For all subsequent scans, the snapshot trace is subtracted from the current trace and the difference, i. Plotting the data in this way makes it easy to detect RF changes that occurred since the initial 'snapshot'.

The 'Threshold Trace' view highlights with a yellow box those frequencies whose signal strength exceeds a user-defined threshold. This feature is especially useful for visually emphasizing strong signals and deemphasizing weak ones , where the user gets to define 'strong' and 'weak' according to where they set the threshold.. For example, in the setting of a live performance where it is important to monitor the channels that have been assigned to wireless audio devices, this feature can be used to ensure those channels are not being impacted by other sources of RF transmissions.

Alternatively, if there are wireless devices that transmit at specific frequencies and you wish to monitor their transmissions, then this mode can be used to verify they are currently operating. For example, in a cell-phone free area, the this feature can be used to monitor the frequency bands used by cell phones for the purpose of detecting prohibited transmissions.
