Enhances roaming efficiency for wireless workgroup bridges by utilizing dual-radio configurations to minimize service disruption and downtime during network transitions.
Dual-radio WGBs are wireless workgroup bridges that
-
use two radios to enhance roaming efficiency,
-
minimize service disruption by skipping the active scanning phase with an existing scanning table, and
-
initiate roaming when beacon frames are missed or packet retry thresholds are reached.
From the Cisco IOS-XE 17.15.1 release, devices with dual-radio configurations have improved roaming efficiency. This reduces service downtime.
Trigger factors for roaming
Trigger factors for roaming include:
-
Low RSSI: Measures the power level that a wireless device, such as an AP, receives from a signal. Use RSSI values to determine the quality of the wireless connection to troubleshoot and optimize wireless networks.
-
Beacon miss-count: Indicates the number of consecutive beacon frames that a client device has missed from an AP in a wireless network.
-
Maximum packet retries: Specifies the maximum number of times a data packet can be retransmitted if the client device does not send an acknowledgement.
Configuration options for dual-radio
Here are the possible configurations for the IW9165E AP in a dual-radio setup:
|
