![]() With noise, you want to get as far away from zero as possible, so -90 is better than -80. For example, an RSSI of -50 is better than an RSSI of -60. RSSI is indicated in negative numbers, and the closer it is to zero the better because zero means that no signal strength has been lost during transmission. ![]() Noise indicates how much interference caused by other signals affects the particular connection. The former stands for “Received Signal Strength Indicator,” and indicates how well a WiFi-enabled device can receive signals from a WiFi router. To determine which non-overlapping WiFi channel is the best, you need to consider Step 1: Understanding RSSI and Noise Values ![]() ![]() In such situations, your best option is to use a WiFi channel scanner or analyzer and find the least crowded non-overlapping channel. In public spaces, apartment buildings, offices, and other densely populated areas, it’s very common for multiple WiFi routers to broadcast simultaneously on a single non-overlapping channel. ![]()
