Figure 2 ASN Reference Model

As viewed from the network architecture and application networking, mobile WiMAX (IEEE 802.16e) is essentially a cellular network oriented to broadband data transmission and is used to implement certain mobility. WiMAX advocates broadband mobile services to implement broadband access at a lower cost, thus allowing the users in hotspot or suburban areas to enjoy the convenience of mobile broadband. Figure 3 depicts the schematic diagram of the WiMAX network.

Figure 5 Distributed Network Structure

At present, network construction faces two challenges: (1) take measures to save equipment room construction investment and shorten construction time, and (2) as frequencies increase, the use of traditional indoor macro BS mode results in the large RF cable loss. Therefore, the radio BS design trends to separate the digital baseband part from the RF part, which is call RRU + BBU structure.

This document is primarily oriented toward the centralized network structure and introduces the remote RF unit in this network structure.



The RRU is a piece of important equipment in distributed BS networking. It implements the RF functions of the baseband-RF interface and the R1 interface. It is located near the antenna port.

ZXMBW R9100 is one of ZTE’s macro cellular coverage RRU products. Its position in the system is shown in Figure 6.

Figure 6 ZXMBW System Structure

• Forward service

The CSN signal is sent to the BBU through the AGW. The BBU is responsible for encoding and modulation of the signal. After that, the signal is sent to the R9100s through fiber-optical. After the R9100s perform IQ modulation, up-conversion, and power amplification, the signal is sent to the MSs through the antennas.

• Reverse service

The MS signal is received by the R9100s through the antennas. The R9100s perform down-conversion and IQ demodulation for the signal. Then the signal is sent to the BBU through the fiber-optical for decoding and demodulation. After that, the signal is sent to the CSN through the AGW.



1.3 Standards Complied ZXMBW R9100 conforms to the following standards and specifications:

• IEEE Standard 802.16-2004, IEEE Standard for Local and Metropolitan Area Networks - Part 16: Air Interface for Fixed Wireless Access Systems

2 Highlight Features ZXMBW R9100 is primarily oriented to outdoor large-capacity macro coverage and can also meet the coverage requirements of the city’s dead zone or hotspot. It has the following characteristics:

• Small size, light weight, and flexible layout 5

The R9100 is merely 19L in size and 17 kg in weight. It supports pole-mounted and wall-mounted installation, which means it is not limited to the equipment room and auxiliary facilities. It supports four-level cascadings and supports star, chain, ring, and hybrid networking modes. It can comprehensively speed up the future WiMAX network construction. 10

• Strong environmental adaptability and easy site selection for engineering installation

• Support various bandwidth applications

Support 5 MHz /10 MHz bandwidth for 2.3G/2.5G; Support 5 MHz / 10 MHz/7MHz for 3.5G. 20

• Support standard interfaces

The baseband-RF interface uses OBSAI-RP3 standards. The RRU can be mounted below the antenna to reduce the RF feeder loss. Besides, it supports flexible networking modes such as star, chain, ring, and hybrid networking. Its interface supports fiber backup to ensure high reliability. 25

• Support multi-voltage support and flexible power supply

Compatible with 220V/110V AC and -48V/+24V DC, the R9100 provides undervoltage /overvoltage protection and reverse polarity protection to greatly improve security and flexibility of the installation while reduce construction and maintenance costs. 30

• To be mounted without room, the design of the ZXMBW R9100 meets the anti-theft demand

• Marks

The board connectors/plugs, jumpers, switches and test point, the power supply and the ground are marked clearly, without obstacles of components, including fuse mark, protection ground mark, warning label, power label, laser label, safety label, energy label and heavy module label. All the marks meet the requirements of safety codes of China or the purchasing country (region). All the marks are clear, complete, easy to understand, and not erasable.

• Overturn protection

The rack is arranged symmetrically to enhance the stability of the equipment provided that the performance indices and heat design requirements are met. In normal conditions, the equipment will not turn over at a plane tilted at 10 degrees. The shell stands external hit.

The rack and the shelf are fixed reliably and are not loose.

• Fire protection

The shell of the BSS, PCB board, cables, power cables that are related to the anti-fire regulations use the inflammable materials. The combustion time after these materials are lit is compliant with the safety standards. The circuit design takes over-current and over-voltage protections into account to prevent overhead caused by normal or faulty conditions. There are fuss and anti-arc resistor protection in the power supply to further prevent overheat and fire caused by shorted circuit. The overall design ensures that the internal flame will not extend to the shell, that is, the shell isolates the fire.

• Mechanical and physical damage

There are no sharp edges, angles, or burrs. There are no mechanical structure defects or technical procedure problems that would lead to human damage.

• Lightning protection



The system has anti-lightning measures. The working ground and the protection ground are reliable and the grounding resistance of the protection ground is less than 10 ohm. The protective grounding terminals are capable of anti-erosion. The grounding cable is 8AWG in size. The insulation layer of the grounding cables is in yellow/green. The bolt that connects the protection ground and the shell (or PCB) has a tooth washer to make the protection ground more reliably connected.

• Components/devices and materials requirements

During the product design, the selection of materials and devices is compliant with UL (or CSA) and VDE (or TUV, NEMKO, and SEMKO) certification. These devices are:

PCB board, fuse, and fuse socket, EMI capacitor, photocoupler, relay, power switch, voltage-selective switch, cables, AC input socket, rheostat, insulation washer and insulation tube, NTC thermistor, plastic materials of the product, connectors, laser module, power module, transformer, fans, and voltage-sensitive resistor (TVS).

• Protective grounding and connection requirements

The protective grounding symbol is near the first protective grounding of the equipment and is easy to see after the PCB is assembled.

The protection grounding terminal does not have switch or over-current protection device.

The protection grounding cable is in yellow/green.

The design of the protection ground ensures that connecting the protection grounding first when accessing the power supply and disconnecting the protection grounding last when shutting off the power supply.

The design ensures that it is unnecessary to disconnect the protection grounding with the dangerous voltage connected during maintenance.

The implementation of the protection grounding function does not depend on the telecommunication network.

• IP Protection Class

The IP protection class is IP65.

• Environmental impact

The equipment uses materials that do not product gases that harm either human beings or the atmosphere or the environment.

The noise produced by the ventilation fan of the equipment will not cause harmful disturbances to the technicians.

The spurious emission produced by the equipment body or the spurious conduction caused by the antenna port will not harm the technicians or the environment.
