About WiMAX
Emanating from the broadband world and using all-IP architecture, mobile
WiMAX is the leading technology for implementing personal broadband services.
With huge market potential and affordable deployment costs, mobile WiMAX is on
the verge of a major breakthrough. No other technology offers a full set of
chargeable and differentiated voice, data, and premium video services in a variety
of wireless fashions - fixed, portable and mobile - that increase revenue and
reduce subscriber churn.
WiMAX technology is the solution for many types of high-bandwidth applications
at the same time across long distances and will enable service carriers to converge
the all-IP-based network for triple-play services data, voice, and video.
WiMAX with its QoS support, longer reach, and high data capacity is positioned
for fixed broadband access applications in rural areas, particularly when distance
is too large for DSL and cable, as well as in urban/suburban areas of developing
countries. Among applications for residential are high speed Internet, Voice Over
IP telephony and streaming video/online gaming with additional applications for
enterprise such as Video conferencing, Video surveillance and secured Virtual
Private Network (with need for high security). WiMAX technology allows covering
applications with media content requesting more bandwidth.
WiMAX allows portable and mobile access applications, with incorporation in
notebook computers and PDAs, allowing for urban areas and cities to become
“metro zones” for portable and mobile outdoor broadband wireless access. As
such WiMAX is the natural complement to 3G networks by offering higher
bandwidth and to Wi-Fi networks by offering broadband connectivity in larger
areas.
The WiMAX Forum is an organization of leading operators and communications
component and equipment companies. The WiMAX Forum’s charter is to promote
and certify the compatibility and interoperability of broadband wireless access
equipment that conforms to the Institute for Electrical and Electronics Engineers
(IEEE) 802.16 and ETSI HiperMAN standards. The ultimate goal of the WiMAX
Forum is to accelerate the introduction of cost-effective broadband wireless access
services into the marketplace. Standards-based, interoperable solutions enable
economies of scale that, in turn, drive price and performance levels unachievable
by proprietary approaches, making WiMAX Forum Certified products.

Figure 1-3: ASN Reference Model containing Multiple ASN-GWs
The various components and entities involved in the networking architecture are:
1.2.2.1
Access Service Network (ASN)
An ASN is defined as a complete set of network functions needed to provide radio
access to a WiMAX subscriber. The ASN provides the following mandatory
functions:
„ WiMAX Layer-2 (L2) connectivity with WiMAX mobile station (MS)
„ Transfer of AAA messages to the WiMAX subscriber's home network service
provider (H-NSP) for authentication, authorization and session accounting for
subscriber sessions
„ Network discovery and selection of the WiMAX subscriber's preferred NSP
„ Relay functionality for establishing Layer-3 (L3) connectivity with a WiMAX MS
(i.e. IP address allocation)
„ Radio resource management
„ ASN-CSN tunneling
„ ASN anchored mobility
4Motion System Manual
4Motion Solution
An ASN is comprised of network elements such as one or more base transceiver
stations and one or more ASN gateways. An ASN may be shared by more than one
connectivity service network (CSN).
1.2.2.2
Connectivity Service Network (CSN)
A CSN is defined as a set of network functions that provide IP connectivity
services to WiMAX subscribers. A CSN may offer the following functions:
„ MS IP address and endpoint parameter allocation for user sessions
„ Internet access
„ AAA proxy or server
„ Policy and admission control based on user subscription profiles
„ ASN-CSN tunneling support
„ WiMAX subscriber billing and inter-operator settlement
„ WiMAX services such as location-based services, connectivity for peer-to-peer
services, provisioning, authorization and/or connectivity to IP multimedia
services, and facilities to support lawful intercept services such as those
compliant with Communications Assistance Law Enforcement Act (CALEA)
procedures
A CSN is comprised of network elements such as routers, proxy/servers, user
databases, and inter-working gateway devices.
1.2.2.3
Network Access Provider (NAP)
An NAP is a business entity that provides WiMAX radio access infrastructure to
one or more WiMAX network service providers (NSPs). A NAP implements this
infrastructure using one or more ASNs.
1.2.2.4
Network Service Provider (NSP)
An NSP is a business entity that provides IP connectivity and WiMAX services to
WiMAX subscribers compliant with the established service level agreement. The
NSP concept is an extension of the Internet service provider (ISP) concept,
providing network services beyond Internet access. To provide these services, an
NSP establishes contractual agreements with one or more NAPs. An NSP may also
establish roaming agreements with other NSPs and contractual agreements with
4Motion System Manual
Chapter 1 - System Description
third-party application providers (e.g. ASP, ISP) for the delivery of WiMAX services
to subscribers. From a WiMAX subscriber standpoint, an NSP may be classified as
a home or visited NSP.
1.2.2.5
Base Station (BS)
The WiMAX BS is an entity that implements the WiMAX MAC and PHY in
compliance with the IEEE 802.16e standard. A BS operates on one frequency
assignment, and incorporates scheduler functions for uplink and downlink
resources.
The basic functionality of the BS includes:
„ IEEE 802.16e OFDMA PHY/MAC entity
„ R6 and R8 functionality according to NWG definitions
„ Extensible Authentication Protocol (EAP) relay
„ Control message authentication
„ User traffic authentication and encryption
„ Handover management
„ QoS service flow management entity
1.2.2.6
ASN Gateway (ASN-GW)
The ASN-GW is a network entity that acts as a gateway between the ASN and
CSN. The ASN functions hosted in an ASN-GW may be viewed as consisting of two
groups - the decision point (DP) and enforcement point (EP). The EP includes
bearer plane functions, and the DP includes non-bearer plane functions.
The basic DP functionality of the ASN-GW includes:
„ Implementation of EAP Authenticator and AAA client
„ Termination of RADIUS protocol against the selected CSN AAA server (home or
visited AAA server) for MS authentication and per-MS policy profile retrieval
„ Storage of the MS policy profile
„ Generation of authentication key material
4Motion System Manual
4Motion Solution
„ QoS service flow authorization entity
„ AAA accounting client
The basic EP functionality of the ASN-GW includes:
„ Classification of downlink data into generic routing encapsulation (GRE)
tunnels
„ Packet header suppression functionality
„ DHCP functionality
„ Handover functionality
The WIMAX Forum NWG has adopted two different approaches for ASN
architecture - centralized and distributed: In the centralized approach there is at
least one central ASN-GW, and the BTS NPU operates in transparent mode, as
shown in Figure 1-4.
Figure 1-4: Centralized Network Reference Model
4Motion System Manual
Chapter 1 - System Description
In the distributed approach, the BTS NPU operates in ASN-GW mode, as shown in
Figure 1-5.
Figure 1-5: Distributed Network Reference Model
Alvarion believes in providing operators with the flexibility to select the mobile
WiMAX network topology that best suits their needs and existing network
architecture. Therefore, 4Motion is designed to support both distributed and
centralized topology approaches according to WiMAX Forum NWG profile C.
1.2.2.7
Reference Points
„ Reference point R1 consists of the protocols and procedures between the MS
and ASN as per the air-interface (PHY and MAC) specifications (IEEE 802.16e).
„ Reference point R2 consists of protocols and procedures between the MS and
CSN associated with authentication, services authorization and IP host
configuration management. This reference point is logical in that it does not
reflect a direct protocol interface between the MS and CSN. The authentication
part of reference point R2 runs between the MS and CSN operated by the
home NSP, however, the ASN and CSN operated by the visited NSP may
partially process the aforementioned procedures and mechanisms. Reference
point R2 might support IP host configuration management running between
the MS and CSN (operated by either the home NSP or visited NSP).
10
4Motion System Manual
4Motion Solution
„ Reference point R3 consists of the set of control plane protocols between the
ASN and CSN to support AAA, policy enforcement and mobility management
capabilities. It also encompasses the bearer plane methods (e.g. tunneling) to
transfer user data between the ASN and CSN.
„ Reference point R4 consists of the set of control and bearer plane protocols
originating/terminating in various functional entities of an ASN that
coordinate MS mobility between ASNs and ASN-GWs. R4 is the only
interoperable reference point between similar or heterogeneous ASNs.
„ Reference point R5 consists of the set of control plane and bearer plane
protocols for internetworking between the CSN operated by the home NSP and
that operated by a visited NSP.
„ Reference point R6 consists of the set of control and bearer plane protocols
for communication between the BS and ASN-GW. The bearer plane consists of
an intra-ASN data path between the BS and ASN gateway. The control plane
includes protocols for data path establishment, modification and release
control in accordance with the MS mobility events.
„ Reference point R8 consists of the set of control plane message flows and
optional bearer plane data flows between the base stations to ensure a fast
and seamless handover. The bearer plane consists of protocols that allow data
transfer between base stations involved in the handover of a certain MS.
It is important to note that all reference points are logical and do not necessarily
imply a physical or even direct connection. For instance, the R4 reference point
between ASN-GWs might be implemented across the NAP internal transport IP
network, in which case R4 traffic might traverse several routers from the source to
the destination ASN-GW.

for NPU redundancy). The remaining seven double-Euro slots are dedicated for
Access Unit (AU) modules, thereby enabling various network topologies and future
redundancy configurations. In addition, the shelf contains an Air Ventilation Unit
(AVU).
1.3.2
NPU
The Network Processing Unit is the controller of the Base Transceiver Station.
Serving as the central processing unit that manages the BTS components, the
NPU aggregates traffic to/from the AU modules, and transfers it to/from the IP
backbone through a dedicated Gigabit/Fast Ethernet interface. In addition, the
NPU can be operated in ASN-GW mode, in which case it also implements ASN-GW
functionality.
When operating in ASN-GW mode, the NPU implements the R3 reference point
toward the CSN, R4 reference point toward other ASN-GWs, and R6 reference
point toward AU/BSs. The R8 reference point traffic is transparently relayed
between AU/BSs (intra- or inter-BTS).
When operating in transparent mode, the NPU transparently relays R6 and R8
reference-point traffic between AU/BSs (intra- or inter-BTS).
The BreezeMAX shelf is hardware-ready for 1+1 NPU card redundancy.
The NPU main functions, when operating in transparent mode, are:
„ Aggregate backbone Ethernet connectivity for user and control traffic
„ Aggregate backbone Ethernet connectivity for management traffic (in-band or
out-of-band)
„ Connection to a cascaded shelf (future feature)

BS capabilities and capacity via software upgrades only, to add more features,
and to comply with future WiMAX Forum profiles. In addition, the SDR approach
prepares the AU for adaptive beam-forming. The AU design is based on Alvarion's
programmable, off-the-shelf, cutting-edge components, in order to provide a
future-proof solution with excellent cost and performance.
The AU card interfaces with the NPU card for R6/R8 functionality, as well as
control, synchronization and management between the NPU and AU.

1.3.4
PIU
The single-Euro Power Interface Unit module serves as the interface between the
DC power source and both the PSU modules and external ODU radio transceivers.
The PIU filters and stabilizes the input power, and protects the system from power
problems such as over-voltage, surge pulses, reverse polarity connection, and
short circuits. It filters high-frequency interference (radiated emissions) and
low-frequency interference (conducted emissions) at the external power source.
Each shelf contains two slots for optional 1+1 PIU redundancy. One PIU is
sufficient to support a fully populated shelf, and two modules provide redundant
power feeding (i.e. from two input sources), while avoiding current flow between
the two input sources.
1.3.5
PSU
The single-Euro Power Supply Unit module is a -48 VDC power supply unit that
generates low-voltage DC output to comply with PICMG 2.x standard
requirements. Each shelf can contain up to four PSU modules supporting N+1
redundancy configuration scheme.
Table 1-2 displays the number of PSU modules (excluding redundant units)
required for various Base Station configurations without NPU redundancy (one

fan tray includes 10 brushless fans (9 fans are sufficient for cooling a fully-loaded
shelf). Fan failure is indicated by both the front panel LEDs and a trap sent to the
management system. To further support high availability, the chassis may
operate without the hot-swappable fan tray for up to 10 minutes until the AVU is
replaced.

ODU
The outdoor unit (ODU) is a high-power, multi-carrier radio unit that connects to
one or more external antennas. It is designed to provide high system gain and
interference robustness utilizing high transmit power and low noise figure. It is
HW-ready for supporting a bandwidth of up to 20 MHz, enabling future options
such as increased capacity through the use of a multiplexer or wider frequency
channels.
The following ODU port configurations will be available:
„ 1x1(1Rx by 1 Tx): One receive port, one transmit port
„ 2x1 (2Rx by 1Tx): Two receive ports, one transmit port
„ 4x2 (4Rx by 1Tx): Four receive ports, two transmit ports
In the current release only 1x1 and 4x2 ODUs are available.
The wide range of ODU types will enable efficient utilization of various second and
fourth order transmit and receive diversity schemes.

Power Feeder
The PIU can support a maximum current of 58 A (@-40.5 VDC). In certain
installations with a relatively high number of ODUs this current may not be
sufficient to power the shelf and all the ODUs. In such installations the ODU
Power Feeder is used as an additional power source providing power (-48 VDC) to
ODUs. It transfers transparently all signals between the AU and the ODU, while
injecting DC power received from an external source. Each ODU Power Feeder
unit can serve up to four ODUs. Up to three ODU Power Feeder units can be
installed in a 1U high Power Feeder panel.
The Power Feeder is not applicable for the configurations supported in the current
release. It will be necessary in the future to support configurations with 6 AUs
where each AU is connected to either six 1x1 ODUs or one 4x2 ODU.
1.3.9
Antenna
In the 4Motion architecture, the antenna is approached as an independent
element. This provides the operator with the flexibility to select the antennas
source according to its supplier policy. To ensure the availability of antennas that
complement the 4Motion solution, Alvarion works closely with several antenna
suppliers to ensure availability of antennas that comply with its requirements.
In cases where the operator prefers other antenna vendors, Alvarion can provide a
recommended antenna specification based on the required antennas types.

For more information on recommended antenna configurations and required
antennas refer to Appendix A.
1.3.10 GPS
GPS is used to synchronize the air link frames of Intra-site and Inter-site located
Base Transceiver Stations to ensure that in all Base Stations the air frame will
start at the same time, and that all Base Stations will switch from transmit
(downlink) to receive (uplink) at the same time. This synchronization is necessary
to prevent Intra-site and Inter-site interference and Base stations saturation
(assuming that all Base Stations are operating with the same frame size and with
the same DL/UL ratio).
In order for the system to be synchronized, the GPS have to first acquire at least 4
satellites. After that the GPS reception can be reduced to 1 satellite.If no satellite
is received the BTS will go to holdover state where internal clock is provided to
synchronize the BTS.

Outdoor GPS Receiver
The all-outdoor GPS Receiver is a pole mountable GPS receiver and antenna in a
single environmentally protected enclosure. The GPS Receiver is powered by a 12

2.1
Installing the ODU
The following sections describe how to install the ODU, including pole mounting
the ODU and connecting the cables.
2.1.1
Guidelines for Positioning the ODU
This section provides key guidelines for selecting the optimal installation locations
for the ODU See also Section 2.2.1 for guidelines on installing the antennas.
CAUTION
ONLY experienced installation professionals who are familiar with local building and safety codes
and, wherever applicable, are licensed by the appropriate government regulatory authorities should
install outdoor units and antennas.
Failure to do so may void the BreezeMAX product warranty and may expose the end user or
Service Provider to legal and financial liabilities. Alvarion and its resellers or distributors are not
liable for injury, damage or regulation violations associated with the installation of Outdoor Units or
antennas.
Select the optimal locations for the equipment using the following guidelines:
„ The ODU is pole mounted. Its location should enable easy access to the unit
for installation and testing.
„ When mounting several ODUs on a pole, make sure that at least one side of
the pole is clear, to enable easy access to all the ODUs.
„ The ODU should be installed as close as possible to the antenna.
2.1.2
IF Cables
ODUs are connected to the AU (or to the ODU Power Feeder) via IF cables carrying
both signals and power. The maximum permitted attenuation of the IF cable at
applicable frequencies, its screening effectiveness and its maximum permitted DC
resistance (the sum of the DC resistance of the inner and outer conductors) are
provided in the following table.

NOTE
The PSU(s) do not supply power to the ODUs that are powered directly from the PIU via the
backplane and the AU cards. The PIU can support up to a maximum of 20 1x1 ODUs. Additional
ODUs should be powered from ODU Power Feeders (not applicable for current release).
Power Calculation Example:
Configuration: A 2.x GHz BTS with 3 AU cards and 4 1x1 ODUs connected to each
AU. Uplink-Downlink split (allocation ratio) of 12-34.
Maximum power consumption that should be supplied by PSUs:
NPU: 68W
3 AUs: 3*46=138W
AVU: 40W
GPS Receiver: 6w
Total maximum power supplied by PSUs: 252W
66
4Motion System Manual
Installing the Base Transceiver Station (BTS) Equipment
Total maximum power required excluding ODUs: 252/0.8 (PSUs Efficiency) + 35
(PIU) = 350W
When calculating the power requirements associated with the ODUs, we should
distinguish between the peak power consumption (maximum current during Tx)
and the average power consumption (taking into account Tx/Rx split ratio) that
affect the requirements from a backup power source.
For a 2.x GHz system, the peak power consumption of 12 ODUs under worst
conditions is 12*89 = 1068W. Thus, the maximum peak power of the system is
350 + 1068 = 1418W (35A @ -40.5 VDC).
The maximum average power consumption of each ODU, assuming UL-DL
(Rx/Tx) ratio of 12-34 is (15*12+89*34)/46 = 70W. Thus, the maximum average
power required for the whole system is 350 + 70*12 = 1190W (29.4A @ -40.5
VDC).
2.3.4
HOT SWAP Support
The NPU, AU, and PIU modules includes a blue HOT SWAP LED and a
micro-switch in the injector/ejector handle to support hot-swap control. After
releasing the ejector's button, the HOT SWAP LED should turn on, indicating that
power to/from the back-panel is disconnected and the module can be removed
safely.
2.3.5
Power Interface Unit (PIU)
The single Euro PIU module serves as the interface between the BTS site's DC
power source and the BTS Chassis Power Supply Units and external ODUs, which
receive power via the IDUs.
The PIU filters and stabilizes the BTS input power and protects the system from
power problems such as over voltage, surge pulses, reverse polarity connection
and short circuits. It also filters high frequency interference (radiated emissions)
and low frequency interference (conducted emissions) to the external power
source. Each BTS chassis contains two slots for 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.

Chapter 2 - Installation
Figure 2-15: PIU Module Front Panel
CAUTION
When replacing a PIU, disconnect power from the PIU module before inserting/ejecting it to/from
the chassis. After disconnecting from power, disconnect the power cable to avoid irreversible
damage due to potential excessively high transient current. Connect power to the PIU only after it is
fully inserted into the chassis.

Preparing a Power Cable for the PIU
A 2.5m DC power cable is supplied with each chassis. Additional DC cables can
be ordered from Alvarion. If necessary, use the following instruction to prepare a
DC cable.
To prepare the power cable:
For a cable length up to 2.5m use a cable with 4 x 10AWG (or thicker) wires for
the power plus and an additional 10AWG (or thicker) ground wire. For a longer
cable (up to 10m), use a cable with 4 x 8AWG (or thicker) wires for the power
plus and an additional 10AWG (or thicker) ground wire.
The matching power connector to be used is D-SUB 5W5S Female with power
pins 40A.
Connect the cable to the power connector as follows:
»
Pin 1 (RTN): Red (10/8 AWG min wire)
»
Pin 2 (-48V): Black (10/8 AWG min wire)

Connecting the BTS Chassis and Modules
The indoor equipment should be installed as close as possible to the location
where the IF cable(s) enters the building. The location of the indoor equipment
should take into account its connection to the power source(s) and to the BTS
networking equipment.
2.3.9.1
Introduction
The BTS modules include special handles for high-force insertion/extraction of
modules. Each of the 6U high modules (NPU, AU) includes two such handles,
whereas each of the 3U high-modules (PIU, PSU) includes a single handle at the
bottom of the front panel.
The bottom injector/ejector handle of the NPU and AU modules includes a
micro-switch to support hot-swap control. Second generation PIU modules also
support hot-swap, as indicated by the HOT SWAP blue LED.
To connect the BTS chassis and modules:
Attach the Cable Guide to the top panel of the chassis using the screws and
washers supplied with the Cable Guide.
Install the chassis in a 19" cabinet. For installation in a 21" cabinet, attach
suitable ETSI rack adapters to the chassis. To provide a sufficient space for
the Cable Guide and to allow air flow for preventing over-heating, leave a free
space of at least 1U between the upper covers of the chassis and other units in
the cabinet.
Connect one end of a grounding cable to the ground terminal located on the
rear panel of the chassis and firmly tighten the grounding screw. Connect the
opposite end of the grounding cable to a ground connection or to the cabinet, if
applicable.
Carefully insert the modules into the relevant slots. Secure the modules in
their alloted locations.
Place blank covers over all unused slots.
Connect the DATA port of the NPU to the backbone data equipment (use a
straight Ethernet cable to connect to a hub/switch/router). The maximum
length of the Ethernet cable is 100m when operating at 100 Mbps and 70m
when operating at 1 Gbps.
