To support a high availability Base Station, the fan tray includes 10 brush-less fans, where 9 fans are sufficient for cooling a fully loaded chassis

Failure in any of the fans is indicated by both the front panel LEDs and a trap that is sent to the management system

To further support high availability, the chassis may operate with the hot-swappable fan tray extracted from it for a period of time sufficient for replacing it (up 10 to minutes)


Network Processing Unit (NPU)

Network Processing Unit (NPU) serves as the heart of the base station, provides:

Aggregate backbone connectivity via a 100/1000 BaseT

Local management port 10/100 BaseT

Traffic classification and connection establishment

Policy based data switching & forwarding

Service Level Agreements management

Base station overall management

Overall operation control and alarm management

Serial port for monitor connection

The bandwidth of each SU is limited by license at the SU side, an NPU license is available to remove the limitation

The bandwidth of CG connections is limited by license at the SU side, an NPU license is available to remove the limitation

Base Station Shelf Components Power Interface Unit (PIU)

• The interface between the base station site’s DC power source (48 VDC) and the Base Station chassis power supply

• Filters and stabilizes the base station input power and protects the system from power problems such as over voltage, surge pulses, reverse polarity connection and short circuits

• Filters high frequency interference (radiated emissions) and low frequency interference (conducted emissions) to the external power source

• Each base station chassis contains two slotsfor an optional 1+1 PIU redundancy

• One PIU is sufficient to support a fully populated chassis

• Two PIU modules provide redundant power feeding (two input sources) while avoiding current flow between the two input sources

• Remove the PIU only after disconnecting itspower cord, failure to comply may cause damage to the equipment

• Frequency 3.3 - 3.8 GHz

• N-Type Connector

Base Station Shelf Components IF Cable

• The AU-ODU is connected to the AU-IDU/Micro Base Station via an IF cable carrying both signals and power

• The maximum permitted attenuation of the IF cable at applicable frequencies depends on its screening effectiveness and its maximum permitted DC resistance

• To comply with the required screening effectiveness requirement, it is recommended to use double shielded cables

• Following are the cables that recommended by Alvarion and their maximum length

– LMR-195 80 m

– LMR-240 150 m

• The IF cable carries– Full duplex data– Control and management signals – Power (-48 VDC) – 64 MHz synchronization reference clock

from the IDU to the ODU– IF Frequencies

• Tx: 240 MHz • Rx: 140 MHz

– IDU-ODU service channel at 14 MHz serves for bi-directional control, status and management signaling

Micro Base Station Components Micro Base Station Indoor Unit

• Provides the full base station functionality necessary for serving a single sector

• There are two different models

– Powered from the AC mains (100 - 240 VAC)

– Powered from a -48 VDC power source

• The functionality of the Micro Base Station is very similar to the combined functionalities of NPU and AU-IDU modules of the modular Base Station

– Backbone Ethernet connectivity via a 10/100 Base-T network interface

– Traffic classification and connection establishment initiation

– Policy based data switching

– Service Level Agreements management

– Centralized agent for management the Micro Base Station unit and all registered SUs

– Alarms management, including external alarm inputs and activation of external devices (future option)


• An SNMP agent incorporated into the unit enables extensive In-Band (IB) management of the Micro Base Station and all its registered SUs

• Out-Of-Band (OOB) management is supported through a dedicated 10/100 Base-T interface

• A serial RS-232 port supports local configuration, monitoring and debugging

• The Micro Base Station also contains the wireless IEEE 802.16a MAC and modem

• The Micro Base Station also includes two 3.5/1.75 MHz PHY channels

• The number of SUs that connect to the microBST might be limited than the specification, depends on the microBST license
