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.

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.

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.
