Smart Roaming

Hi, user_3357613

1. rrm-profile name wlan-rrm
2. smart-roam roam-threshold check-snr check-rate  //it mean ap will check both snr and rate of station
3. smart-roam roam-threshold snr 30  // SNR threshold is 30 dB and noise floor is -95 dBm, when the STA's RSSIis lower than -65 dBm (30 dB + (-95 dBm) = -65 dBm). AP sends a Disassociation frame to the STA so that the STA can reinitiate a connection with the AP or roam to another AP with strong signals.
4. smart-roam roam-threshold rate 30  // If the maximum capability of the AP and STA is 54 Mbit/s and the rate threshold is 30%, the lower rate threshold is considered 16.2 Mbit/s (54 Mbit/s x30% = 16.2 Mbit/s). The AP sends a disassociation frame to the STA so that the STA can reinitiate a connection with the AP or roam to another AP with strong signals.

Whats the difference between soft roaming, hard roaming and smart roaming, ?
