R250D&R250D-E Product Description 1 Product Positioning and Characteristics  Issue 01 (2016-07-05) Huawei Proprietary and Confidential                                     Copyright © Huawei Technologies Co., Ltd. 1  1 Product Positioning and Characteristics 1.1 Product Positioning Product Overview The R250D and R250D-E are remote units (RUs) used in Huawei agile distributed Wi-Fi solution. They support PoE power supply, and are deployed indoors and connected to the central AP.    The central AP and RUs are connected through network cables, which greatly extends the coverage range, enhances flexibility in AP deployment and planning, and reduces the engineering construction costs. The central AP manages the RUs and processes services in a centralized manner. The RUs process radio signals independently. Such distributed architecture further improves the wireless access capability, creating optimal service experience for users. The RU uses an 86 mm plate in compliance with international standards and can be easily installed into a junction box in a room. It is equipped with a built-in antenna and a hidden indicator; therefore, installation of the RU does not affect indoor decorations and designs. It also has an IEEE 802.11a/b/g/n/ac/ac wave2 wireless module and can work on both 5 GHz and 2.4 GHz frequency bands. The RU is recommended for environments with complex wall structures and high-density rooms, such as schools, hotels, hospitals, and office meeting rooms. Signals are transmitted through network cables without attenuation. The RUs are deployed indoors and provide comprehensive signal coverage. The RUs are managed by the central AP. The central AP and RUs are plug-and-play and can be managed and maintained in real time. Compared with traditional distributed AP solutions, the AC in Huawei agile distributed Wi-Fi solution needs to manage a smaller number of APs. A large number of RUs can be deployed, which improves the overall performance and reduces network deployment costs.
R250D&R250D-E Product Description 1 Product Positioning and Characteristics  Issue 01 (2016-07-05) Huawei Proprietary and Confidential                                     Copyright © Huawei Technologies Co., Ltd. 2  Usage Scenario Figure 1-1 Distributed wireless access   As shown in the figure, the downlink GE interfaces of the central AP support PoE power supply and can be directly connected to RUs. The central AP can connect to more RUs through a PoE switch. RUs are deployed indoors and communicate with the central AP through network cables. 1.2 Product Characteristics Long-Distance Network Coverage Unlike the traditional distributed AP which allows for a maximum feeder length of 15 m, the central AP uses network cables to replace feeder cables and supports up to 100 m distance from the RUs. The network coverage range is therefore expanded by several times. No Wall Penetration Loss, No Coverage Hole Restricted by feeder length or installation requirements, signals have to pass through walls in some scenarios, resulting in large signal attenuation. If rooms to be covered have complex structures, coverage holes may occur. To prevent these problems, lots of calculation and verification work needs to be carried out. Huawei distributed solution solves these problems. In this solution, RUs are placed in rooms, and signals are transmitted over wired cables, without wall penetration loss, delivering high-quality wireless access services.
R250D&R250D-E Product Description 1 Product Positioning and Characteristics  Issue 01 (2016-07-05) Huawei Proprietary and Confidential                                     Copyright © Huawei Technologies Co., Ltd. 3  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.

Therefore, one central AP can use RUs to cover dozens of rooms. Hierarchical Processing Technology, High Wireless Forwarding Capability Huawei distributed solution uses innovative hierarchical processing technology. The central AP manages RUs in a centralized manner and concurrently forwards service traffic, while the RUs only process radio signals. The hierarchical design makes the network structure clearer and reduces the processing burden on the central AP and RUs, improving efficiency and optimizing the overall wireless forwarding performance.

These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:   —Reorient or relocate the receiving antenna.   —Increase the separation between the equipment and receiver.   —Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.   —Consult the dealer or an experienced radio/TV technician for help.   FCC Radiation Exposure Statement    This device complies with FCC radiation exposure limits set forth for an uncontrolled environment and it also complies with Part 15 of the FCC RF Rules. This equipment must be installed and operated in accordance with provided instructions and the antenna(s) used for this transmitter must be installed to provide a separation distance of at least 25 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter. End-users and installers must be provide with antenna installation instructions and consider removing the no-collocation statement.    This device complies with Part 15 of the FCC Rules. Operation is subject to the
