Description

AirEngine 6761-21 overview

Huawei AirEngine 6761-21 is an indoor access point (AP) in compliance with the Wi-Fi 6 (802.11ax) standard. The AP uses built-in smart antennas to ensure always-on Wi-Fi signals for users, significantly enhancing users’ wireless network experience. It provides uplink 10GE optical and 2.5GE electrical ports, facilitating flexible deployment and saving the customer investment. These strengths make the AP ideal for densely populated scenarios such as mobile office, education, and stadiums.

  • Working simultaneously on the 2.4 GHz (4×4) + 5 GHz (4×4) frequency bands
  • 1 x 2.5GE electrical port + 1 x 10GE optical port (optical/electrical port, supporting hybrid cables)
  • Independent scanning radio for scanning the air interface without affecting service performance, thereby achieving real-time monitoring and optimization for WLAN network quality
  • Built-in smart antennas that automatically adjust the coverage direction and signal strength based on the intelligent switchover algorithm to adapt to the application environment change, and provide accurate and stable coverage as STAs move
  • USB port for IoT expansion
  • Bluetooth serial interface-based O&M through the built-in Bluetooth module by collaborating with CloudCampus APP; collaboration with a location server to accurately locate Bluetooth terminals and tags
  • Working modes: Fit, Fat, and cloud management
