Ap761 Wi-fi 6 11ax Outdoor 2+2 Dual Bands Built-in Antenna Ble

Features:

Wi-Fi 6 (802.11ax) standard 

• As the latest Wi-Fi standard defined in IEEE 802.11, 802.11ax improves the user access capacity and bandwidth in high-density access scenarios, reduces service latency, and enhances user experience.
• Multi-user multiple-input multiple-output (MU-MIMO) on both the 2.4 GHz and 5 GHz frequency bands, allowing an AP to transmit data to and receive data from multiple STAs simultaneously and multiplying the utilization of radio spectrum resources.  802.11ax supports 1024-QAM, delivering 25% higher data transmission efficiency than 802.11ac (supporting 256QAM).
• Orthogonal Frequency Division Multiple Access (OFDMA) technology enables the AP to transmit data to multiple STAs at the same time using different subcarriers, reducing latency and improving network efficiency.
• Spatial multiplexing technology uses basic service set (BSS) coloring mechanism to enable the AP and STAs to distinguish overlapping BSSs, minimizing co-channel interference.
• Target Wake Time (TWT) technology allows the AP and STAs to negotiate the sleep and wake time with each other, thereby improving the battery life of the STAs.

 

MU-MIMO 

The AP supports MU-MIMO and supports a maximum of four spatial streams (two on the 2.4 GHz frequency band and two on the 5 GHz frequency band). The MU-MIMO technology enables an AP to send data to multiple STAs simultaneously, which doubles the radio spectrum resource usage, increases the number of access users and bandwidth, and improves user experience in high-density access scenarios.

 

High-speed access 

The AP supports 80 MHz frequency bandwidth, which increases the number of available data subcarriers and expands transmission channels. In addition, the AP adopts 1024-QAM and MU-MIMO to achieve a rate of up to 0.575 Gbps on the 2.4 GHz band and 1.2 Gbps on the 5 GHz band, meaning up to 1.775 Gbps for the device.

 

High-specification protection

Extended temperature range of –40°C to +65°C with a metal shell and an overall heat dissipation design, IP68 waterproof and dustproof design, and 6 kA surge protection for Ethernet ports, meeting industrial-grade requirements
Cable connectors are secured using metal fasteners to ensure secure connections and stable device operations.
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:

SmartRadio for air interface optimization

• Load balancing during smart roaming: The load balancing algorithm is used to perform load balancing detection on APs after STAs roam, and adjust the STA load on each AP accordingly to improve 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. Through automatic interAP negotiation, the redundant radio is automatically switched to another mode 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 STA. This ensures that each STA is assigned a relatively equal amount of time for using channel resources and user services are scheduled in an orderly manner, improving service processing efficiency and user experience.

Air interface performance optimization

• In high-density access scenarios, access of many low-rate STAs consumes many resources on the air interface, compromises the AP capacity, and degrades user experience. To address this issue, the AP checks the access rate of STAs and denies access of low-rate or weak-signal STAs. In addition, the AP monitors the rate and signal strength of online STAs in real time, and forcibly disconnects low-rate or weak-signal STAs and then steer such STAs to APs with stronger signals. This STA access control technology can increase air interface efficiency and allow access of more STAs.

5G-prior access

• The AP supports both 2.4 GHz and 5 GHz frequency bands. The 5G-prior access function enables the AP to steer STAs to the 5 GHz frequency band preferentially, which reduces loads and interference on the 2.4 GHz frequency band, improving user experience.

 

Wired and wireless 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 AP supports WEP, WPA/WPA2-PSK, WPA3-SAE, WPA/WPA2-PPSK, WPA/WPA2/WPA3-802.1X, and WAPI authentication/encryption modes to ensure the security of wireless networks. 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 data can only be received and parsed by authorized users.

Analysis on non-Wi-Fi interference sources

• The AP can perform spectrum analysis to identify non-Wi-Fi interference sources, including baby monitors, Bluetooth devices, digital cordless phones (on the 2.4 GHz frequency band only), wireless audio transmitters (on both the 2.4 GHz and 5 GHz frequency bands), wireless game controllers, and microwave ovens. Coupled with Huawei’s NMS, the AP can accurately detect interference sources and display their spectrum, helping administrators eliminate the interference in a timely manner.

Rogue device monitoring

• The AP provides the wireless intrusion detection system (WIDS)/wireless intrusion prevention system (WIPS) attack detection mechanism to monitor, identify, defend against, contain, and perform refined management on rogue devices, providing security guarantees for air interface environment and wireless data transmission.

Authentication and encryption for wired access

• The AP access control mechanism ensures that only authorized users can access the AP. CAPWAP link protection as well as DTLS and IPsec encryption provide security guarantee and improve data transmission security between the AP and WAC.

 

Automatic radio calibration 

Automatic radio calibration allows the AP to collect signal strength, channel, and other parameters of surrounding APs and generate an AP topology according to the collected data. Based on interference from other authorized APs, rogue APs, and non-Wi-Fi interference sources, and their loads, the 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 

The AP uses smart application control technology to implement visualized management and control over Layer 4 to Layer 7 applications.

Traffic identification

• Coupled with a Huawei WAC, the AP can identify over 1500 common applications in various office scenarios. Based on the identification results, the AP can perform policy control on user services, including priority adjustment, scheduling, blocking, and rate limiting, to maximize bandwidth utilization and improve quality of key services.

Traffic statistics collection

• Traffic statistics of each application can be collected globally, by SSID, or by user. In this way, network administrators can gain insights into application use status on the network, and network administrators or operators can implement visualized control on service applications on smart terminals, enhancing security and ensuring efficient bandwidth control.

 

Leader AP 

In small- and medium-sized enterprises (SMEs), one AP can be configured as the leader AP and function as the virtual WAC to manage other Fit APs. In addition, no AP management license needs to be purchased, which effectively reduces customer investment.

 

Cloud management 

The AP supports cloud-based management. It provides various authentication functions, such as PSK, Portal, SMS, and social media authentication, without the need of a WAC or an authentication server. This greatly simplifies networking and reduces CAPEX. In addition, the AP can be deployed on a cloud management platform to implement cloud-based network planning, deployment, inspection, and O&M. In multi-branch deployment scenarios, after cloud APs are preconfigured on the cloud management platform, deployment personnel only need to power on the cloud APs on site, connect them to network ports of switches, and scan their QR codes to achieve plug-and-play. Then the pre-configurations are automatically delivered to the APs. This greatly accelerates network deployment. The cloud management platform can monitor the network status, device status, and STA connection status at all sites of tenants in a comprehensive and intuitive manner.
