Product Description
Huawei R251D-E Remote Units
R251D-E mainframe(11ac Wave 2,2x2 dual bands,built-in smart antenna,USB,BLE,PSE)
Huawei R251D and R251D-E are gigabit remote units (RUs) in compliance with 802.11ac Wave 2 in Huawei Distribute Wi-Fi
Solution. They can be easily installed in a room and are connected to a central AP through Ethernet cables. The central AP
manages the RUs for central service forwarding. The RUs process radio signals independently. Such as solution greatly improves the WLAN coverage range and makes AP deployment more flexible. With mounting brackets, RUs can be easily adapted to junction boxes (86/118/120 mm) and wall-mounting scenarios. The R251D and R251D-E boast built-in smart antennas, a hidden indicator, and a "morning dew" style. These highlights make the RUs suitable for environments with densely distributed small rooms, such as hotel guest rooms, student dormitories, hospital wards, and small offices.
