802.11ac/ac wave2 Gigabit Wireless Rate
The RU complies with IEEE 802.11a/b/g/n/ac/ac wave2, supports 2x2 MIMO, works on both
2.4 and 5 GHz frequency bands, and provides strong signals and gigabit wireless rate.
Unique, Graceful Plate Design
The RU is white in appearance and has heat emission holes and interfaces at the side and
bottom. The mounting screws are hidden under the slide panel. The overall design is simple
but graceful and blends well with the layout of hotels and apartments.
Easy to Install in a Standard 86-type Box
The RU uses an 86 mm plate in compliance with international standards and can be easily
installed into a junction box in a room, requiring no drilling or cabling.
Flexible Installation Modes
In addition to an 86-type box, the R250D can be installed on a wall or ceiling, and the
R250D-E can be installed on a desk, rendering the installation location flexible.
Hidden Indicator, Zero Impact on Sleep
The RU uses a hidden indicator design. When being turned on, the indicator has soft light.
The AC controls the switch of the indicator and turns off the indicator at nights to prevent
blinking lights from affecting sleep of guests.
Four Downlink Ethernet Interfaces, Supporting Wired Access from Multiple
Users
The R250D-E has four downlink 1000M Ethernet interfaces that can process data
concurrently. The interfaces can be connected to multiple terminals through network cables,
such as the IPTV, desktop computer, and laptop, meeting requirements of hotels and
apartments. One downlink 1000M Ethernet interface supports PoE out and can provide power
supply for connected devices such as IP phones.
Auto Shutdown of the Wired Interface
In some cases, a loop may occur on a network connected to the RU's wired interface, for
example, when the RU and the network are connected through a hub. The auto shutdown
function enables the RU to automatically shut down its wired interface for protection.
This function takes effect only when the wired network connected to the RU's wired interface does not
terminate STP packets from the RU.
Low Engineering Cost
Compared with traditional distributed APs, the central AP cuts down the following expenses:
Construction: Network cables replace expensive feeder cables. The central AP can
directly use the network cables originally routed in the rooms, without the need of
deploying new cables.
