When enabled on the global radio settings, Cisco access points advertise their channel and transmit power level in the beacons and probe responses. If using 2. Use the CMU-DEVICE wireless network for smart devices that typically do not support web browsers or login (authentication) capabilities. If no radar is detected on the projected channel for at least one minute, then the new radio service device may begin transmissions on that channel. It automatically selects a frequency that does not interfere with the radar systems. Products (1) Cisco 5500 Series Wireless. 2 Antenna Details Ant. The process for a radio to detect and identify a radar signal is a complicated task that sometimes leads to incorrect detects. Cisco Bug: CSCvc41438 - WGB running 15. If radar pulses are detected, that channel is black-holed for at least 30 minutes. This only adds the needed registry change for DFS channels. Different vendors use different ways to report the events, at my company we use Cisco WLC and it only reports DFS-events via SNMP-traps. The Cisco® Aironet® 2800 Series Wi-Fi access points are highly versatile and deliver the most functionality in the industry.
