Product features

Large-capacity and high-performance design

The AC6805 is capable of supporting medium and large campuses with up to 6K APs.

Provides 2 x 40 GE optical interfaces, 12 x 10 GE optical interfaces and 12 x GE electrical interfaces, supporting up to 40 Gbit/s forwarding performance.

Note: One 40 GE port is mutually exclusive with four 10 GE ports.

SmartRadio for air interface optimization

Load balancing during smart roaming: The load-balancing algorithm can work during smart roaming for load balancing detection among APs on the network after STA roaming to adjust the STA load on each AP, improving network stability.

Intelligent DFA technology: The Dynamic Frequency Assignment (DFA) algorithm is used to automatically detect adjacent-channel and co-channel interference, and identify any 2.4 GHz redundant radio channels. Through automatic inter-AP negotiation, the redundant radio channel is automatically switched to another mode (dual-5G AP models support 2.4G-to-5G switchover) or is disabled to reduce 2.4 GHz co-channel interference and increase the system capacity.

Intelligent conflict optimization technology: The dynamic Enhanced Distributed Channel Access (EDCA) and airtime scheduling algorithms are used to schedule the channel occupation time and service priority of each user. This ensures that each user is assigned relatively equal time for using channel resources and user services are scheduled in an orderly manner, improving service processing efficiency and user experience.

Various roles

The AC6805 has a built-in Portal/AAA server and can provide Portal/802.1X authentication for users, reducing customer investment.

Flexible networking

The WLAN AC can be deployed in inline, bypass, bridge, and Mesh network modes, and supports both centralized and local forwarding.

The WLAN AC and APs can be connected across a Layer 2 or Layer 3 network. In addition, NAT can be deployed when APs are deployed on the private network and the WLAN AC is deployed on the public network.

The WLAN AC is compatible with Huawei full-series 802.11n, 802.11ac, and 802.11ax APs and supports hybrid networking of 802.11n, 802.11ac, and 802.11ax APs for simple scalability.

Built-in application identification server

Supports Layer 4 to Layer 7 application identification and can identify over 6,000 applications, including common office applications and P2P download applications, such as Lync, FaceTime, YouTube, and Facebook.

Supports application-based policy control technologies, including traffic blocking, traffic limit, and priority adjustment policies.

Supports automatic application expansion in the application signature database.

Comprehensive reliability design

Supports redundant AC power supplies and hot-swappable power supplies.

Supports WLAN AC 1+1 HSB, and N+1 backup, ensuring uninterrupted services.

Supports port backup based on the Link Aggregation Control Protocol (LACP) or Multiple Spanning Tree Protocol (MSTP).

Supports WAN authentication escape between APs and WLAN ACs. In local forwarding mode, this feature retains the online state of existing STAs and allows access of new STAs when APs are disconnected from WLAN ACs, ensuring service continuity.

Built-in visualized network management platform

The AC6805 has a built-in web system that is easy to configure and provides comprehensive monitoring and intelligent diagnosis.

Health-centric one-page monitoring, visualized KPIs

One page integrates the summary and real-time statistics. KPIs are displayed in graphs, including user performance, radio channel performance, and AP performance, enabling users to extract useful information from the massive amounts of monitored data, while also knowing the device and network status instantly.

Monitoring interface

Profile-based configuration by AP group simplifies configuration procedure and improves efficiency.

The web system supports AP group-centric configuration and automatically selects the common parameters for users, meaning that users do not need to pre-configure the common parameters, simplifying the configuration procedure.

If two AP groups have small configuration differences, users can copy the configurations of one AP group to the other. This improves configuration efficiency because users only need to modify the original configurations, not create entirely new ones each time.

Configuration interface

One-click diagnosis solves 80% of common network problems

The web system supports real-time and periodic one-click intelligent diagnosis from the dimensions of users, APs, and WLAN ACs, and provides feasible suggestions for troubleshooting the faults.
