Hardware WiFi signal analyzers: Aimed at professional network administrators and security experts, hardware WiFi signal analyzers are physical devices used for troubleshooting and performance testing.The good news is that WiFi analyzers have become readily available at a variety of price points, and they can be roughly divided into two categories:

Without knowing how to use a WiFi analyzer, it’s very difficult for home users, small businesses, and schools to provide reliable coverage and the best data transfer speeds possible. These days, WiFi networks are everywhere, and our expectations of them have never been greater. In the past, WiFi analyzers were used predominantly by large organizations and enterprises that needed to cover a large area with a strong WiFi signal. The purpose of a WiFi analyzer is to gather as much information as possible about available wireless networks to help professionals and home users alike troubleshoot WiFi-related problems, ensure optimal router placement, and more. WiFi analysis isn’t hard to do, provided you use a good WiFi analyzer app, and its benefits are plentiful. WiFi analysis performed using a wireless network analyzer can reveal which WiFi channels are used the least and provide plenty other information necessary for comprehensive WiFi optimization. In theory, 11 channels should be more than enough even for densely populated urban areas, but, in reality, people seldom change the default configuration of their wireless router, which results in a situation where too many wireless routers transmit data on the same channel. In North America, the 2.4 GHz radio band is divided into exactly 11 channels, with channels 1, 6, and 11 being the only channels that don’t overlap with other channels. This radio band is divided into multiple channels, which are like the lines on the highway. Most wireless routers use the 2.4 GHz radio band to transmit data. But with at least one wireless router in nearly every home, the WiFi radio spectrum can get cluttered pretty easily.

The best WiFi signal strength software can even turn the gathered data into heatmap visualizations, showing exactly where dBM values are high and where they are low, allowing even beginners with limited technical knowledge to instantly spot signal weakspots and other issues.ĭo you want to know how is WiFi signal strength measured using WiFi signal strength software? Then continue reading.Any modern home isn’t modern without a wireless router.

WiFi signal strength Mac and Windows WiFi signal strength software applications can detect all available WiFi networks and instantly reveal how strong the signals emitted by them are, making it easy to find the strongest network in any location and troubleshoot connectivity issues caused by interference and other common problems.īesides allowing you to test WiFi signal strength, WiFi signal strength software can also be used to optimize the deployment of multiple WiFi hotspots by ensuring that they together provide even coverage of the entire area where you want wireless internet to be available. The other half is collecting and analyzing WiFi data to determine the current dBm value of your signal, and that’s where wireless signal strength software comes in. Knowing what the WiFi signal strength dBm values mean and understanding how they can affect your online experience is only one half of the battle. What Is the Purpose of WiFi Signal Strength Software? Of course, you want the Signal-to-Noise ratio to be as high as possible so that it’s less likely for a signal to disappear in environmental noise. For example, if you receive a signal of -70 dBm and the noise floor is measured at – 80 dBm, the SNR is 10 dB. You can see just how much noise there is by measuring the Signal-to-Noise ratio (SNR), which is the difference in decibels between the received signal and the background noise level. If you’re in the same room as your wireless router and have trouble achieving good network performance, the chances are that there is a lot of environmental noise from various electronic devices and other wireless networks. Signal strength between -55 dBm and -75 dBm is acceptable, depending on how close or far away from your wireless router you happen to be. Generally, -80 dBm is considered to be the minimum signal strength for basic connectivity, while -67 dBm is good WiFi signal strength even for streaming and other demanding tasks.
The closer this number is to zero, the stronger the signal is.
