What is Cisco CleanAir technology?
Cisco® CleanAir™ technology uses silicon-level intelligence to create a spectrum-aware, self-healing, and self-optimizing wireless network that mitigates the impact of wireless interference and offers performance protection for 802.11n and 802.11ac networks.
What is WiFi AOCI?
Adjacent Off Channel Interference (AOCI)—This is interference from a Wi-Fi device that is not on the reporting operating channel, but is overlapping the channel space.
What is wireless network Cisco?
Cisco wireless networking combines the mobility of wireless with the performance of wired networks, offering a dramatic performance increase compared to legacy 802.11a/g networks. Cisco delivers 802.11n and 802.11ac excellence designed to effectively support a vast range of business-focused wireless networks.
What is Edrrm?
Event-Driven Radio Resource Management (EDRRM) Event-Driven RRM is a feature that allows an access point that is in distress to bypass normal RRM intervals and immediately change channels.
What is RRM in Cisco WLC?
Group Leader is the WLC with highest group leader priority. RRM is per radio band(ie separate groups for 2.4 GHz & 5 GHz) & two WLC can be group leader for these two. To configure RRM, you would need to given an RF group name for the controller. That’s pretty much it for most of deployments.
Which authentication methods are most commonly used in enterprise wireless deployments?
Define Your Authentication Mechanism The most commonly adopted and recommended authentication mechanism is EAP. An added advantage of EAP is that it supports both types of authentication. Your choice of EAP type is impacted by many factors, including the following: The client devices you intend to support.
What are the 5GHz channels?
In the 5GHz band, we have channels ranging from 36 up to 165, and in the 6 GHz band, we have Wi-Fi channels ranging from 1-233. Both frequencies allow for channel width from 20 MHz-160 MHz).
What are three options of RRM?
RRM enables controller to monitor their associated AP for the following information.
- Traffic Load (how many clients in a given AP)
- Interference (coming from other 802.11 soruces)
- NOise (non-802.11 that interfere with current CH)
- Coverage (RSSI & SNR for all connected CH)
- Other APs (number of nearby AP)
What is DCA in Cisco WLC?
DCA, or Dynamic Channel Assignment, is a core component of Cisco Radio Resource Management (RRM). It runs a critical algorithm which dynamically changes an access points (AP) client serving channel based on multiple parameters, collectively called a Cost Metric.
