FIGURE 3 APPEARANCE

Basic Principle

System Structure

Based on the easily extensible and flexible MicroTCA (also calledTCA) open standard communication service platform, the ZXSDRB8200 W100 is composed of the following modules:

Control and Clock module (CC)

X BaseBand Process module (XBP)

Site Alarm module (SA)

Fan Array module (FA)

Power Module (PM).

Figure 4 shows the ZXSDR B8200 W100 system structure.



FIGURE 4 SYSTEM STRUCTURE

Service Flow

The ZXSDR B8200 W100 service flow is described as follows:

Forward service

The service signals from the AGW are sent to the ZXSDR B8200W100 through TDM or Ethernet. After R6 interface protocoltermination, they are sent to the baseband MAC and PHY layerprocessing modules for WiMAX protocol processing through thegigabit Ethernet. After undergoing crossover, framing, paral-lel-to-serial conversion, the demodulated IQ data is distributedto RRUs through the OBSAI optical interface.

Reverse service

The service signals from RRU are multiplexed and processedat PHY and MAC layer. After being demodulated, they undergoR6 interface protocol processing and then are packetized intoEthernet frames. Afterwards, these Ethernet frames are trans-mitted to the CC module to process through the gigabit Ether-net before being sent to AGW through TDM or Ethernet.

Networking

R6 Interface Networking

R6 interface connects an AGW with a ZXSDR B8200 W100 throughan E1/T1 or a GE/FE Ethernet physically. Figure 11 illustrates theR6 interface networking architecture.

FIGURE 11 R6 INTERFACE NETWORKING ARCHITECTURE

A ZXSDR B8200 W100 can access an AGW through an E1/T1.

Every ZXSDR B8200 W100 is directly connected to aTDM transmission network in point-to-point mode, andthen to an external IP-TDM protocol convert before beingconnected to the AGW.

An AGW can access a ZXSDR B8200 W100 through the GE/FEEthernet interface by using the following methods:

Connect the AGW to the ZXSDR B8200 W100 through anetwork cable.

Connect the AGW to the ZXSDR B8200 W100 through aHub or a switch.

Connect the AGW to one or more ZXSDR B8200 W100sthrough a router.



Baseband-RF Interface NetworkingMode

The baseband-RF interface is located between ZXSDR B8200W100and RRU, complying with the OBSAI protocol. Fibers are usedto connect baseband-RF interfaces physically. In ZXSDR B8200W100, each XBP provides four optical interfaces.

Figure 12 illustrates the baseband-RF interface networking archi-tecture.

FIGURE 12 BASEBAND-RF INTERFACE NETWORKING ARCHITECTURE

As shown in Figure 12, the BBU and RRU support chain networking,star networking and combination of the two networking modes.

In a star network, every RRU is connected to the BBU in thepoint-to-point mode. This networking mode is more reliablethan the chain networking mode but costs more transmissionresources.

In a chain network, multiple RRUs form a chain and then areconnected to the BBU. This networking mode is more reliablethan the chain networking mode applicable to the areas in banddistribution. It costs less transmission resources but is lessreliable than the star networking mode.

Operation and MaintenanceSystemFigure 13 illustrates the management architecture of ZXSDRB8200 W100.



FIGURE 13 ZXSDR B8200 W100 MANAGEMENT ARCHITECTURE

The ZXSDR B8200 W100 supports the following two operation andmaintenance modes:

LMT, which is a local network management system provided bythe WEB server of every NE. It is a WEB browser for on-sitemaintenance of BSs.

OMC (i.e., NetNumen M3(WiMAX OMC-B)), which is used toremotely manage NEs.

Here describes the ZXSDR B8200 W100 operation and mainte-nance through OMC.

The NetNumen M3(WiMAX OMC-B) network management sys-tem integrates the management of the global network to pro-vide a complete operation and maintenance function. It supportsZTE WiMAX series products, centralizes the management of theseproducts and provides standard northbound interfaces for the up-per-level network management system.

The NetNumen M3 (WiMAX OMC-B) provides abundant appli-cable management functions, satisfying various management re-quirements in actual network operations.

It delivers the maintenance functions required by TMN Specifi-cation such as configuration management, alarm management,security management and performance management, as well astopology management, system management, log management,tool console and integrated system analysis. These functions helpoperators accurately understand the operation status of networkdevices so that they can maintain these devices in time to ensurethe best operation status of the system.

GPS Antenna Feeder System

GPS Antenna Feeder System Structure

GPS signal is the system clock and frequency reference. The GPSantenna feeder receives the navigation and location signals fromthe GPS satellite. The clock module demodulates the frequencyand clock signals and provides them to corresponding modules ofZXSDR B8200 W100.

The GPS antenna feeder system is used for indoor ZXSDR B8200W100 installation, as shown in Figure 27.
