What is the minimum RSSI signal for a data WLAN?

The correct answer is D. -80 dBm. Cisco design guidelines define different minimum RSSI thresholds based on application type. For general data (non-real-time) WLANs, the minimum acceptable RSSI is –80 dBm (D). For voice/real-time applications, the threshold is much stricter at –67 dBm. For location services…

Explanation

Cisco design guidelines define different minimum RSSI thresholds based on application type. For general data (non-real-time) WLANs, the minimum acceptable RSSI is –80 dBm (D). For voice/real-time applications, the threshold is much stricter at –67 dBm. For location services, –72 dBm is recommended. These thresholds reflect the fact that data applications can tolerate more signal degradation and retransmissions, whereas voice and video are latency-sensitive. Understanding these values is essential for proper cell sizing during site surveys.
