A customer is acquiring a new VoWLAN system to replace their existing wired phone system. When reading about his system's requirements, you learned that is requires 25 db of SNR to work as expected. After surveying the environment, you discovered that the noise floor is -88 dBm. What should be the minimum RSSI value to meet the system's requirements?

After deploying a 5 GHz-only WLAN infrastructure in the USA, using 20 MHz channel widths and all 25 available channels, a manager tests the Guest SSID on his 802.11n tablet. During testing, he experiences several areas with poor RSSI (below -80 dBm) or no signal at all. Upon checking, all APs are operational, and coverage was validated post-deployment. What is the likely cause of this issue?

Of the following antenna connector types, which one is the smallest?

What limitation exists when WMM is not enabled on an 802.11n WLAN?
