Radio signals grow weaker as the distance between the transmitter and receiver increases. Meanwhile, the data rate for a given client will adjust dynamically depending on the distance and signal strength. As the distance between AP and client increase, the signal strength will decrease. As the signal strength decreases, the current data rate cannot be maintained. The transmitting device will drop ....Read more

It’s true that Wi-Fi network documentation isn’t the most fun thing to do. In fact, it can be such an eye-rolling task that engineers in many organizations avoid it until necessary. In some cases, documentation is considered a low priority task – until a problem strikes. When troubleshooting a critical problem, good Wi-Fi network documentation can mean the difference between quick resolution and c....Read more

SNR, or Signal to Noise Ratio, also dBm, or decibel margins, is a measurement of how strong a signal is through the noise of the medium it is traveling through. It is the ratio of Signal to Noise. For example, a Signal of -24dBm with a noise of -90dBm would yield a SNR of 66dB. SNR Connection Quality 10dB - 15dB Unreliable Connection 16dB - 24dB Poor 25dB - 40dB Good 41dB or Greater Excellent Nois....Read more
