R230D&R240D Product Description 1 Product Positioning and Characteristics Issue 02 (2015-10-31) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd.1 1 Product Positioning and Characteristics 1.1 Product Positioning Product Overview The R230D and R240D are remote radio units (RRUs) 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 RRUs 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 RRUs and processes services in a centralized manner. The RRUs process radio signals independently. Such distributed architecture further improves the wireless access capability, creating optimal service experience for users. The RRU 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 RRU does not affect indoor decorations and designs. It also has an IEEE 802.11a/b/g/n/ac wireless module and can work on both 5 GHz and 2.4 GHz frequency bands. The RRU 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 RRUs are deployed indoors and provide comprehensive signal coverage. The RRUs are managed by the central AP. The central AP and RRUs 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 RRUs can be deployed, which improves the overall performance and reduces network deployment costs.

R230D&R240D Product Description 1 Product Positioning and Characteristics Issue 02 (2015-10-31) 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 RRUs. The central AP can connect to more RRUs through a PoE switch. RRUs 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 RRUs. 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, RRUs are placed in rooms, and signals are transmitted over wired cables, without wall penetration loss, delivering high-quality wireless access services.

R230D&R240D Product Description 1 Product Positioning and Characteristics Issue 02 (2015-10-31) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd.3 802.11ac Gigabit Wireless Rate The RRU complies with IEEE 802.11a/b/g/n/ac, 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 RRU 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 RRU 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 The R230D can be embedded into an 86-type box or mounted to a ceiling or wall. Its installation positions can be flexibly planned. Hidden Indicator, Zero Impact on Sleep The RRU 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 R240D has four downlink 100M 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. 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.  License: The maximum number of central APs in Fit AP mode allowed by the AC is controlled by licenses, but RRUs do not require licenses. Therefore, one central AP can use RRUs to cover dozens of rooms. Hierarchical Processing Technology, High Wireless Forwarding Capability Huawei distributed solution uses innovative hierarchical processing technology. The central AP manages RRUs in a centralized manner and concurrently forwards service traffic, while the RRUs only process radio signals. The hierarchical design makes the network structure clearer and reduces the processing burden on the central AP and RRUs, 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

R230D&R240D Product Description 4 Technical Specifications Issue 02 (2015-10-31) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd.26 antenna(s) used for this transmitter must be installed to provide a separation distance of at least 20 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 following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Caution!  Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.
