Power (Power (––VeVe) 48 Volt for CAPC) 48 Volt for CAPC
CAPCAP--C CapacityC Capacity
AP Capacity:
The CAP-C is required to support a maximum of 1000 APs. The CAP-C will have a total of 5 active pCAPCs in a fully configured system. Therefore, each pCAPC and the components executing as part of that pCAPC must support a maximum of 200 APs.
Subscriber Capacity:
The subscriber capacity within the CAP-C is determined by the type of traffic, the mobility of that traffic, and the overall throughput that the traffic is introducing within the CAP-C. In WMX 1.0, total 1,000,000 subscribers can be upported by a CAP-C node and each pCAPC can support upto 200,000 subscribers.
CAP-C System Controller
Controller and Switching Blade. The System Controller provides both redundant layer-2 switching and system management.
CAP-C Payload Blade
Each CAP-C blade will be equipped with 8 GB ECC-enabled DDR2 RAM and can be extended up to 16 GBs. Each CAP-C will also be equipped with a rear transition module that comes equipped with dual GbE ports and a Fujitsu 37GB Serial Attached SCSI hard drive used for storing local software and logging information.
Power Entry Module (PEM)
The CAP-C chassis has PICMG 3.0 compliant, dual PEMs and is rated for -40VDC to - 72VDC.
Fan Tray Modules (FTM)
The CAP-C chassis supports three upper and one lower FTM. Each upper FTM houses 4 separate fans and are arranged for maximum volume air flow, even distribution, and fault tolerance.
Rear Transition Module (RTM)
The CAP-C System Controller will come equipped with a RTM that will provide connectivity to external devices. 4 GbE ports will be allocated for extending the data interface fabric to provide connectivity to an external IP network. 8 GbE ports will be reserved for future multi-chassis CAP-C support.
CAP-C Interfaces
1.CAP-C Physical Interface
CAP-C is physically connected to the IP network via the Ethernet interface. Typically, there will be routers in between the CAP-C and other WiMAX network entities, such as AP, AAA and EMS. Each active blade (System Controller or pCAPC) of CAP-C willhave a unique IP address for communication within the IP network.
2. CAP-C Logical Interface Types
There are three types of logical interfaces implemented in the CAP-C node for the system communication and operation management. The logical interfaces are defined as follows:
1. External Communication Interface2. Internal Communication Interface3. Operational Interface
1.External Communication InterfaceThis interface includes the following logical connections.
• CAP-C – AP• CAP-C – CAP-C• CAP-C – AAA• CAP-C - EMS• CAP-C – Router
The connections for CAP-C – AP, CAP-C – CAP-C and CAP-C - Router are controlledby CAP-C Link Management function. The communication between the CAP-C andAAA is being managed by the CAP-C AAA proxy server, which is the Authenticatorcomponent. For communication to the EMS, the CNEOMI-Lite Agent is implemented inthe CAP-C product and acts as the interface between the CAP-C and EMS.
2. Internal Communication InterfaceThe internal communication interface is implemented for messageprocessing between components. This interface will not have exposure to the network entities outside CAP-C node.
3. Operational Interface
The CAP-C Operational Interface consists of the following:• Local Maintenance Terminal (LMT)• CAP-C Shell Access
LMT is a web-based interface, which is used for day-to-day operations including account management, debugging CAP-C, alarm and statistics management, etc. CAP-C Shell Access is utilized to commission the CAP-C for the first time. This interface will not be used for normal operations.

Base Control Unit Components View
Site Controller
It is primarily a digital processing card that contains a microprocessor platform for the site level software, a frequency/timing reference circuit, an Ethernet switch, and interfaces for backhaul and site alarms and I/O. The BCU cabinetcontains slots for two site controllers in a redundant (1+1) mode.
Modem Card
It is a digital baseband card that contains a host microprocessors, DSPs, and an FPGA for performing 802.16e MAC and PHY rocessing. There are four modem slots in the BCU. The typical configuration requires one modem card per sector. Alternatively,one modem per two sectors can also be configured using a trunkedconfiguration.
Alarm/IO
It provides connectivity to the backhaul, remote GPS receiver and
customer I/O.
Power Supply
The BCU contains slots for three mains power supply units. Only two are required to power a fully populated site, the third can be optionally installed to allow for N+1 redundancy.
2.1.6 FansThe BCU is cooled by forced air via the air plenum and contains a fan tray containing a single fan. The fan has a tachometer output that allows it to be alarmed approximately one week before it actually fails. Similar designs have achieved >90% success in alarming fans before failure.
BackplaneThe backplane allows for interconnectivity of the site controllers, modems, and the Alarm/IO card. It also provides +27 VDC power to each of the cards.
Surge ProtectorThe BCU has two surge elements. There’s a module that protects the mains power input and there is a surge card that protects the backhaul, GPS, customer I/O, and power feeds to the RF heads.

Smart Antenna RF HeadSmart Antenna RF Head• Antenna Gain ~ 14 dBi per element• TX power 1 Watt per antenna• Supports adaptive beam forming
– Increases coverage (6 – 10 dB link improvement)– Enables adaptive interference cancellation. Important
for full 1x1 cell reuse patterns without significant capacity loss
– Improves throughput at given distance from antenna site– Self calibrating adaptive antenna system for optimal
performance• Can also support MIMO in a reduced mode using subset of
array• Redundancy
– Independent RF transceivers offers limited loss of RF coverage with single RF failure
– Redundant optical fiber link to BCU cage for redundant modem and optical link support
– Redundant calibration transceiver for adaptive antenna optimization
General RulesGeneral Rules
• 1 RF Head = 1 RF Carrier frequency– Expansion: Widen RF channel or add RF heads and BCU
• 1 Modem card supports 1 RF Head (usually)– For Diversity Antenna RF head, 1 Modem can support up
to 3 RF heads at 1/3 capacity each. Lowest cost, lowest capacity sector option.
– For Smart Antenna RF head, always use 1 Modem card per RF Head
– Modem Card capacity optimized for 10 MHz channels• Each RF Head must always map to a single modem card
– No pooling of modem resources across modem cards• 100 meter max distance between BCU and RF Head
connections• All sites must be synchronized
– GPS for system timing– Same duty cycle (downlink to uplink ratios)
