Description
802.11ac Wave 2 compliance, MU-MIMO (2SU-2MU), delivering services simultaneously on 2.4G and 5G radios (400 Mbit/s at 2.4 GHz, 867 Mbit/s at 5 GHz, and 1.267 Gbit/s for the device)
One GE uplink port, four GE downlink ports, and two RJ45 pass-through phone ports (compatible with RJ11)
Various installation modes for easy deployment, including junction box–mounting, wall-mounting, and desk-mounting
USB port used for external power supply and storage
Built-in smart antennas, improving the coverage area
Supports the Fat, Fit, and cloud modes and enables Huawei cloud management platform to manage and operate APs and services on the APs, reducing network O&M costs
Huawei AP2051DN-S is a gigabit wall plate access point (AP) targeted at the SMB distribution market in compliance with 802.11ac Wave 2. With mounting brackets, the AP can be easily adapted to junction boxes (86/118/120 mm) and wall-mounting scenarios. The AP2051DN-S boasts built-in smart antennas, a hidden indicator, and a brand-new “morning dew” style. These highlights make the AP suitable for environments with densely distributed small rooms, such as hotel guest rooms, student dormitories, hospital wards, and small offices. The APs provide enhanced service support capabilities and feature high security, simple network deployment, automatic AC discovery and configuration, and real-time management and maintenance. The AP2051DN-S can connect to wireless terminals through wireless connections or to wired terminals using wired cables. This makes the AP the ideal choice for customers to construct indoor distributed networks.
