Huawei eKitEngine AP661 Wi-Fi 6 Access Point

Huawei eKitEngine AP661 is an indoor AP in compliance with Wi-Fi 6 (802.11ax). It can simultaneously provide services on 2.4 GHz (2×2 MIMO), 5 GHz (2×2 MIMO) and 5 GHz (4×4 MIMO) frequency bands, achieving a device rate of up to 6.575 Gbps. Built-in smart antennas of the AP enable always-on Wi-Fi signals for users, significantly enhancing users’ wireless experiences. These strengths make it ideal for densely populated scenarios such as mobile office, education, and stadiums.

Built-in smart antennas that automatically adjust the coverage direction and signal strength based on the intelligent switchover algorithm to adapt to changes in the external environment, in addition to providing accurate and stable coverage as stations (STAs) move, USB port for IoT expansion (such as ZigBee and RFID) , Working modes: Fit, Fat, and cloud management

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 256- QAM). 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.

MU-MIMO

The AP supports MU-MIMO and supports a maximum of eight spatial streams, two spatial streams on the 2.4 GHz frequency band and six spatial streams on the 5 GHz band (two on the high-frequency band and four on the lowfrequency 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.

Smart antenna

The dual-band smart antenna array technology and intelligent switchover algorithm enable the AP to intelligently sense the application environment and access density, achieving accurate Wi-Fi coverage and interference suppression. They together provide the optimal coverage direction and signal quality for each access STA, and offer seamless and smooth wireless network experience to users.

High-speed access

The AP supports 160 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 6 Gbps on the 5 GHz band, meaning up to 6.575 Gbps for the device. 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.

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.
