    Smart high-density antenna

    Embedded with smart antennas purpose-built for high-density scenarios, the AP is easy to install, reducing network deployment costs. The directional coverage can mitigate interference between APs, meeting high-density coverage requirements of indoor stadiums.

    PoE out function

    When the AP uses 802.3at PoE power supply, the Ethernet interface GE1 supports the PoE out function and can be used to provide power for other devices.

    MU-MIMO

    The AP supports MU-MIMO. MU-MIMO technology allows an AP to send data to multiple STAs at the same time (currently, most 802.11n/11ac Wave 1 APs can only send data to one STA simultaneously). The technology marks the start of the 802.11ac Wave 2 era.

    GE access

    The APs support the 80-MHz bandwidth mode. Frequency bandwidth increase brings extended channels and more sub-carriers for data transmission, and a 2.16-fold rate increase. Support for High Quadrature Amplitude Modulation (HQAM) at 256-QAM increases the 5 GHz radio rate to 867 Mbit/s and the AP rate to 1.267 Gbit/s.

    Cloud-based management

    Huawei Cloud Managed Network (CMN) Solution consists of the cloud management platform and a full range of cloud managed network devices. The cloud management platform provides various functions including management of APs, tenants, applications, and licenses, network planning and optimization, device monitoring, network service configuration, and value-added services.

    High-density boost technology

    Huawei uses the following technologies to address challenges in high-density scenarios, including access problems, data congestion, and poor roaming experience:

  • Interference suppression
  • In high-density scenarios, APs are usually densely placed. Huawei uses small-angle antennas that are purpose-built for high- density scenarios to mitigate interference. These antennas have good radiation angle control and can regulate AP coverage radius to within the appropriate range. Additionally, Huawei’s Clear Channel Assessment (CCA) optimization technology reduces the possibility of air interface resources shared by multiple devices, allows higher user access, and improves the throughput.

  • Air interface performance optimization
  • In high-density scenarios where many users access the network, increased number of low-rate STAs consumes more resources on the air interface, reduces the AP capacity, and lowers user experience. Therefore, Huawei APs will check the signal strength of STAs during access and rejects access from weak-signal STAs. At the same time, the APs monitor the rate of online STAs in real time and forcibly disconnect low-rate STAs so that the STAs can reassociate with APs that have stronger signals. The terminal access control technology can increase air interface use efficiency and allow access from more users.

  • 5G-prior access (Band steering)
  • The APs support both 2.4G and 5G frequency bands. The 5G-prior access function enables an AP to steer STAs to the 5 GHz frequency band first, which reduces load and interference on the 2.4 GHz frequency band, improving the user experience.

  • Load balancing between APs
  • After the load balancing function is enabled, the AC distributes users evenly to APs based on user quantity and traffic volume. Traffic load is therefore balanced among APs to ensure stable AP performance.

  • Smart roaming
  • Smart roaming technology is based on the 802.11k, 802.11v, and 802.11r technologies and allows STAs to connect to APs with stronger signals, improving user experience and the overall performance of the wireless network.

  • Agile Beam
  • Agile antenna polarization beam automatic adaption.

    Wired and wireless dual security guarantee

    To ensure data security, Huawei APs integrate wired and wireless security measures and provide comprehensive security protection.

  • Authentication and encryption for wireless access
  • The APs support WEP, WPA/WPA2–PSK, WPA/WPA2–802.1x, and WAPI authentication/encryption modes to ensure the security of the wireless network. The authentication mechanism is used to authenticate user identities so that only authorized users can access network resources. The encryption mechanism is used to encrypt data transmitted over wireless links to ensure that the data can only be received and parsed by expected users.

  • Analysis of non-Wi-Fi interference sources
  • Huawei APs can analyze the spectrum of non-Wi-Fi interference sources and identify them, including baby monitors, Bluetooth devices, digital cordless phones (at 2.4 GHz frequency band only), wireless audio transmitters (at both the 2.4 GHz and 5 GHz frequency bands), wireless game controllers, and microwave ovens. Coupled with Huawei eSight, the precise locations of the interference sources can be detected, and the spectrum of them displayed, enabling the administrator to remove the interference in a timely manner.

  • Rogue device monitoring
  • Huawei APs support WIDS/WIPS, and can monitor, identify, defend, counter, and perform refined management on the rogue devices, to provide security guarantees for air interface environment and wireless data transmission.

  • AP access authentication and encryption
  • The AP access control ensures the validity of APs. The CAPWAP link protection and DTLS encryption provide security assurance, improving data transmission security between the AP and the AC.

    Automatic radio calibration

    Automatic radio calibration allows an AP to collect signal strength and channel parameters of surrounding APs and generate AP topology according to the collected data. Based on interference from authorized APs, rogue APs, and non-Wi-Fi interference sources, each AP automatically adjusts its transmit power and working channel to make the network operate at the optimal performance. In this way, network reliability and user experience are improved.

    Automatic application identification

    Huawei APs support smart application control technology and can implement visualized control on Layer 4 to Layer 7 applications.

  • Traffic identification
  • Coupled with Huawei ACs, the APs can identify over 1,600 common applications in various office scenarios. Based on the identification results, policy control can be implemented on user services, including priority adjustment, scheduling, blocking, and rate limiting to ensure efficient bandwidth resource use and improve the quality of key services.

  • Traffic statistics collection
  • Traffic statistics of each application can be collected globally, by SSID, or by user, enabling the network administrator to know application use status on the network. The network administrator or operator can implement visualized control on service applications on smart terminals to enhance security and ensure effective bandwidth control.
