hi kids, this is your dad, huahuanjayy wkwkwk, Nuenomaru the handsome is back in action.
Okay, this time your dad is going to write a tutorial Ruijie access point roaming using AI roaming in the cloud.
Roaming Introduction:
*An STA moves from one AP to another AP and associates with the new AP.
*When environment variables are changed, and the STA finds that the service quality of AP-B is better than that of AP-A, the STA sends an association request to AP-B. AP-B confirms the association request.
*During roaming, network services are not interrupted, and the user identifier (IP address) is not changed.
*Layer 2 roaming: An STA roams between APs in the same subnet.
*Layer 3 roaming: An STA roams between APs in different subnets.
Roaming Protocol Introduction:
*The 802.11k protocol enables APs and STAs to exchange wireless status information, helping STAs quickly select a roaming AP by collecting and reporting nearby AP data for better roaming recommendations.
*The 802.11v protocol enable wireless devices and APs to exchange network topology and signal environment information, improving the overall network. APs not only respond to neighbor AP reports but also evaluate connection quality and guide STAs to the best AP for better Internet access experience, balancing AP loads.
*With the cooperation of 802.11v and 802.11k, the roaming target AP is determined.
AI Roaming on Ruijie Cloud:

*AI roaming significantly enhances the roaming experience by combining AI with wireless clients and the IEEE 802.11k and 802.11v standards.
*AI adapts to the unique signal reception capabilities and roaming strategies of different clients, addressing challenges in complex environments such as high-density deployments and sudden signal drops.
*By using a scenario-based matching approach, AI ensures smoother and more efficient roaming.
*AI Dynamic Optimization: After it is toggled on, the system intelligently optimizes the roaming handover timing based on the real-time status of clients and APs in complex network environments.
*To ensure smart roaming, when the topology changes, please scan the wireless network again.
*After configuring roaming, Ruijie Cloud Pro provides a view of the device roaming status, enabling the evaluation of wireless roaming performance.
Basic Troubleshooting:
1 Phenomenon
In an office scenario, a client reported that roaming is often slow when walking around, causing problems with sending images and messages on phones and tablets.
2 Roadmap
Check AI Roaming page, find out the signal quality is poor and RSSI is –80 dbm (below normal value).
This indicates a sticky roaming issue, with a STA struggling to roam. The low RSSI value suggests limited signal coverage, causing the STA to connect to the old AP instead of finding a new one while moving.
3 Method
Appropriately increase the AP power and reduce the roaming sensitivity.
Hahaha alright, that’s a wrap for today’s article—my coffee’s gone, so that’s my cue to stop typing.
Let’s end this with a Bismillah at the start and an Alhamdulillah at the finish. Catch you next time, tech gembelers!.
