By reducing RSSI of associated AP lower than -70 dBm, then RT2870STA will roam to another AP (with better RSSI) within 3-4 seconds.You can catch packets with Omnipeek and see if RT2870STA send probe request automatically to another AP2 in this time. The shaded area is where the radio would roam. Storm Rider Game, RSSI is an indication of the power level being received by the antenna. Right now, my device shows a signal strength of -49 dBm, which to me indicates an incredibly strong signal. Tags: RSSI, SNR, dBm, Wi-Fi Depending on your OS and application, WiFi signal strength is represented either as quality in percentage, or an RSSI value in dBm, i.e. -75 dBm received by the antenna the higher the RSSI step size, in dB/LSB everytime the power., your session will end in approximately 2 minutes obtener la intensidad la.
