System ArchitectureArchitecture Figure 9 illustrates the ZXMBW B9100 system architecture.

FIGURE 9 SYSTEM ARCHITECTURE

Signal Flow Forward Service

The ZXMBW B9100 receives the forward service from AGWthrough R6 interface, and implements signal coding and mod-ulation. After that the coded and modulated signal is transmit-



ted to the RRU via fiber or local connection. The RRU performsradio modulation, amplification and filtration on the signal, anthen the signal is radiated through the antenna and receivedby access terminals.

Reverse Service

The antenna receives the reverse service that from access ter-minals, and passes the service to the RRU. The RRU performsradio demodulation on the service. The demodulated signal istransmitted to ZXMBW B9100 through fiber or local connec-tion. The ZXMBW B9100 decodes the signal, and sends thesignal to core network via R6 interface.

Signal Flows

Service Signal Flow

In ZXMBW B9100, control plane signal flow and media plane signalflow are combined into one signal flow.

Forward SignalFlow

Figure 10 shows the forward service signal flow.

FIGURE 10 FORWARD SERVICE SIGNAL FLOW


Chapter 2 Work Principle

The service signal from CN flows through AGW and into the CSIMboard via R6 interface. After Ethernet switch, it is distributed toMPXM, MPIM and WBPM to finish the MAC and PHY processing ofbaseband modulation, and then sent to RRU through the base-band-RF optical interface.

Reverse SignalFlow

Figure 11 shows the reverse signal flow.

FIGURE 11 RESERVE SERVICE SIGNAL FLOW

The RF signal from MS flows into WBPM board through the base-band-RF optical interface. After Ethernet switch, MPXM, MPIM andWBPM completes the MAC and PHY processing of baseband de-modulation. Finally, the signal is sent to AGW via the R6 interfacein CSIM board.

Clock Signal Flow

ZXMBW B9100 system clock is wholly distributed by TFM.

TFM processes received satellite signals and outputs PP1S, 4CHIPand SerDes clock signals. Afterwards, it distributes these clocksignals to each board of ZXMBW B9100, as shown in Figure 12.



FIGURE 12 CLOCK SIGNAL DISTRIBUTION

Power DistributionThe external -48 V power supply goes through the DC power cableto PM via its panel inlets. PM processes and outputs voltages of12 V and 3.3 V for distribution into each board in the cabinet.

Ventilation andHeat-dissipation PrinciplesZXMBW B9100 adopts forced aircooling with front intake andrear exhaust. It is equipped with 3 separated fan units.


Chapter 2 Work Principle

The cool air blows into the cabinet through the air intake vent atthe bottom and goes upwards through the air exhaust vent at top.

Figure 13 shows the air flow in the ZXMBW B9100 air channel.

ZXMBW B9100 and AGWNetworking

One AGWConnected toMultiple BSs

ZXMBW B9100 supports the star networking mode with AGW, asillustrated in Figure 14.

FIGURE 14 ZXMBW B9100-AGW STAR NETWORKING

Every ZXMBW B9100 is connected to AGW through transmissionmedium, which facilitates network maintenance and engineeringinstallation because of high line reliability.



One BS Connectedto Multiple AGWs

To improve the reliability and AGW disaster recovery capability,one BS is connected to multiple AGWs. Both layer 2 and layer 3exchanges between BS and AGWs are supported.

1. In layer 2 mode,

One BS is connected to multiple AGWs through a layer 2 switch,as illustrated in Figure 15.

FIGURE 15 BS CONNECTED TO MULTIPLE AGWS VIA LAYER 2 SWITCH

In this mode, the external IP address of MPXM is in the samesubnet with interface IP addresses of these AGWs. Because allmedia plane and signaling plane packets sent to an AGW shouldbe transferred by the interface of the AGW, the correspondingroute table should be configured in MPXM.

2. In layer 3 mode,

The external IP address of MPXM, interface IP addresses, sig-naling IP addresses and media plane IP addresses of AGWs canbe in different subnets. In this mode, the media plane and sig-naling plane packets sent to any AGW should be only routed tothe external router connected to the MPXM because of simpleconfiguration of MPXM.

Figure 16 illustrates the layer 3 connectivity mode.


Chapter 3 Networking and Configuration

FIGURE 16 BS CONNECTED TO AGWS VIA LAYER 3 SWITCH

Baseband-RF InterfaceNetworkingZXMBW B9100 supports a star or chain networking with RRU.

Star Networking In star networking, each RRU connects directly to ZXMBW B9100via optical fiber, as is shown in Figure 17.

GPS Antenna FeederSystem

GPS Antenna Feeder SystemStructure

GPS signal is the reference clock and reference frequency for theBBU system. GPS antenna feeder system receives the positioningsignals from GPS satellites. The TFM demodulates and extractsthe frequency and clock signals to send them to each unit in theZXMBW B9100.

Different GPS antenna feeder system structure is implemented ac-cording to the installation mode of the ZXMBW B9100 cabinet.

For ZXMBWB9100 Indoor

Installation

When the ZXMBW B9100 is installed indoors, the GPS antennafeeder system structure implemented is as shown in Figure 55.

GPS Feeder

Functions The GPS feeder performs following functions:

Connects the GPS antenna with the clock module.

Transmits signals received by the GPS antenna to the clockmodule for proper processing.

Transmits the DC 5 V power generated by the clock module tothe GPS antenna as the working voltage.

PE insulation impedance is 50 ohm. It is one-layer bare copperbraided shielded.

Structure When the GPS feeder length is less than 100m, 1/4" RF coaxialcable can be used. 1/4" RF coaxial cable appearance is shown inFigure 57
