There is a wide range of applications to choose from, e.g. Various other trademarks are held by their respective owners.Using modern mobile devices, you can easily determine the level of Wi-Fi signal from the access point in different rooms of the apartment, private house, or office.įor example, take your Android smartphone or tablet and install a special free application to determine free channels and check the quality of Wi-Fi signal reception and strength. WatchGuard and the WatchGuard logo are registered trademarks or trademarks of WatchGuard Technologies in the United States and other countries. If you have a -41dBm signal strength, and a -96dBm noise level, this results in an excellent signal-to-noise ratio of +55dB.If you have a -41dBm signal strength, and a -50dBm noise level, this results in a poor signal-to-noise ratio of +9dB.
Lower values than +25dB result in poor performance and speeds.
Negative values indicate less background noise.The closer the value to 0, the greater the noise level.This is the power ratio in decibels (dB) of the measured power referenced to one milliwatt. Noise level is measured in -dBm format (0 to -100).If the noise level is too high, it can result in degraded strength and performance for your wireless signal strength.The noise level indicates the amount of background noise in your environment.
For example, -41dBm is better signal strength than -61dBm. The closer the value is to 0, the stronger the signal.Signal strength is represented in -dBm format (0 to -100).Strong signal strength results in more reliable connections and higher speeds.The signal strength is the wireless signal power level received by the wireless client. To make sure that all users in your environment receive a strong wireless signal, consider these guidelines when you install your WatchGuard APs. Wireless Signal Strength and Noise Levels
