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.
PoE OUT power supply
The AP2050DN-E supports PoE OUT and can supply power to STAs such as IP phones (providing that the AP uses 802.3at or DC
1-meter Bluetooth location
The AP2050DN-E supports built-in Bluetooth. In compliance with BLE4.1, the AP2050DN-E can work with eSight to achieve precise Bluetooth location.
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.
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:
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 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.

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 on 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 the 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.
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.
