Description

Huawei AP661 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
Feature Description
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.
 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 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.
