2 Introduction

This section provides a descriptive overview of the product and its place in the product suite.

2.1 General Overview

2.1.1 HiperMAX

As highly flexible and scalable WiMAX Base Stations, the HiperMAX ATCA and HiperMAX-micro are capable of supporting Mobile WiMAX and Fixed WiMAX profiles across multiple frequency bands.

HiperMAX ATCA and SDR-micro are macro-cell base stations with a split indoor / outdoor architecture designed to support multiple transceivers and smart antenna techniques. They are base-station solutions optimised for supporting high availability WiMAX services through various levels of system element redundancy.

2.2 Where HiperMAX fits into the Network Architecture

The WiMAX network is divided into two main parts:

Access Service Network (ASN)

Connectivity Service Network (CSN)

HiperMAX is part of the ASN. The ASN consists of WiMAX Base Stations and the ASN Gateway (GW), and from a business perspective is assumed to be owned by the Network Access Provider (NAP).

Figure 1 – WiMAX Network Reference Model



3 HiperMAX-System Components

3.1 HiperMAX ATCA Hardware Components

This is a representation for illustration only; actual layout may differ as infrastructure is installation-specific.

Figure 2 – HiperMAX ATCA Hardware Components

The HiperMAX Base station is optimised for traditional multi-sector macro-cell deployments consisting of a baseband section, suitable for location within a protected environment, and an outdoor RF section. The system will therefore operate from existing macro-cell sites, used in traditional cellular deployments. The indoor boards, referred to as blades within the ATCA standard, are housed in an ATCA chassis. The outdoor enclosure contains the RF subsystem components, which enables smart antenna functionality running on a Software Defined Radio (SDR).

HiperMAX is designed to implement a 1, 2, 3 or 4 channel element array for a variety of supported frequency bands. HiperMAX Base stations will also support Adaptive Antenna System (AAS) and Multiple In, Multiple Out (MIMO) for OFDMA operation. MIMO operation, running over the HiperMAX antenna array is expected to enhance capacity by two or three times and improve frequency re-use, compared with traditional methods.

The connection between the indoor and outdoor equipment is achieved through a fibre-optical cable and separate power feed.



3.2 HiperMAX-micro Hardware Components

This is a representation for illustration only; actual layout may differ as infrastructure is installation-specific.

Figure 3 – HiperMAX-micro Hardware Components

The all outdoor HiperMAX-micro consists of split baseband and RF sections connected via a fibre interface, but with all power supply and synchronisation functionality housed within a single SDR-micro enclosure. This form factor is particularly well suited to low density micro-cell sites where access to a temperature-controlled room is not possible or preferred, e.g. a building rooftop.

3.3 HiperMAX Management Options

As an Airspan WiMAX-compliant platform, HiperMAX supports three management options:

Local web-based client management of individual system components, which is used to configure small systems and networks.

Management via third-party SNMP management tool, which uses standard WiMAX MIB.

Netspan network management, which is based on the Microsoft .NET Framework, uses standard WiMAX MIB and delivers support for 1) distributed server architecture, 2) full system configuration and OAM activities, 3) SNMP API.



Figure 4 – Netspan in WiMAX Network Architecture

The Netspan server supports an SQL database for configuration and alarm storage with an option for third-party access directly to the database via SNMP. The client(s) are accessed by way of current web browsers and connects to the server via IP.



4 HiperMAX System Architecture

4.1 HiperMAX ATCA System Components

HiperMAX is a high-performance modular system based on the Advanced Telecom Computing Architecture (ATCA) equipment practice, consisting of:

ATCA shelf with 5 or 14 slots

Dual redundant ATCA shelf controllers

One or more SDR boards, executing the WiMAX PHY and MAC layers

Masthead-mounted radio transceivers: single channel radio transceiver (SCRT) or future variants

External antennas, for use with SCRT

Optional Ethernet switch blade.

Figure 5 – HiperMAX Functional Components



4.1.1 HiperMAX ATCA Chassis

4.1.1.1 HiperMAX ATCA Chassis 14-slot

The HiperMAX BS consists of an indoor unit and outdoor antennas. The indoor boards are housed in a 14-slot dual star Advanced Telecom Computing Architecture (ATCA) chassis for HiperMax configurations. 5-slot ATCA chassis are available for smaller systems. The ATCA chassis is designed to mount directly into a 19 inch rack. Brackets are required to mount in an ETSI rack. The 14slot chassis is 13U high.

Figure 6 – HiperMAX ATCA Shelf 14-slot

The 5 slot chassis uses 6U ATCA equipment chassis with 5 slot shelf/backplane powered from an external -48vdc supply.

The backplane provides 3 payload slots for HiperMAX SDR blades, 2 slots for Ethernet switch blades and 2 dedicated shelf manager slots.

The chassis is equipped with:

2 front power entry modules

1 hot swap fan tray

shelf alarm panel



4 front blanking panels fitted in vacant shelf slots

1 full rear blanking panel

air filter

4.1.1.2 HiperMAX ATCA Chassis 5-slot

The 5 slot chassis uses 6U ATCA equipment chassis with 5 slot shelf/backplane powered from an external -48vdc supply.

The backplane provides 3 payload slots for HiperMAX SDR blades, 2 slots for Ethernet switch blades and 2 dedicated shelf manager slots.

Figure 7 – HiperMAX ATCA Shelf 5-slot

The chassis is equipped with:

2 front power entry modules

1 hot swap fan unit

shelf alarm panel

4 front blanking panels fitted in vacant shelf slots

1 full rear blanking panel

air filter



4.1.1.3 HiperMAX Asis Chassis 5-slot Type B

The 5 slot chassis uses 6U Asis equipment chassis with 5 slot shelf/backplane powered from an external -48vdc supply.

Figure 8 – HiperMAX Asis Shelf 5-slot Type B

Backplane features include:

Five slots

Fabric interface with dual star interconnect.

The Fabric Interface grid consists of eight differential pairs per channel.

The Base Interface grid consists of four differential pairs per channel.

Dual-star Ethernet signalling environment on the Base interface.

Bussed IPMI (radial IPMI available upon request).

Hub slots are slots 1&2.

Update channel between slots 1&2 and 3&4.

10, 100 and 1000 BASE-T dual star Base Interconnect capability.

Update channel interfaces for active and standby synchronization

Connection capacity for up to five third-party ATCA-compliant front boards, as well as to the redundant Shelf Manager Board and redundant Power entry module units.



Full compliance with AdvancedTCA™ electrical and mechanical specifications (Basic backplane topology is “dual star”.)

Interconnect for system power for five slots.

Base Interface Channel 1 of Logical Slot 1 is routed to the left dedicated.

Shelf Manager slot on the ATCA Backplane. Base Interface Channel 1 of Logical Slot 2 is routed to the right dedicated Shelf Manager slot on the ATCA Backplane.

There are no active components on the backplane, and no removable or serviceable parts on the backplane board excluding the ID E²proms.

The backplane has two functionally-distinct parts: right and centre left:

Right backplane (consists of Zone 1 connectors) – dual-power connections, which means the power connections from the Power supplies are independently supplied to each module plugged into the backplane. The modules also include fuses that protect the backplane power connections from an electrical short on a module.

Centre left backplane (consists of Zone 2 connectors) – connectivity for the Base, Fabric, and update-channel interface. This portion supports a full-mesh topology for both the Base and the Fabric interfaces.

4.1.2 HiperMAX ATCA GPS Receiver

The GPS Receiver GPSR-R-19-1 consists of a 19” rack mounted enclosure housing a GPS receiver module and a signal distribution board. The unit outputs two 10MHz and 1pps clock synchronisation signals. It is powered by external 48V supply with redundancy.

The GPS receiver provides an accurate frequency derived from the Coarse Acquisition Link 1 signals transmitted by the Navstar Global Positioning System (GPS) satellites. The GPS input is used as the reference for the tracking function. When no valid input reference is available, the GPS receiver enters hold-over mode and holds its output frequency to the one that was available just before the loss of the input.

The receiver:

Supplies ITU-T G.811 references with valid GPS signal

Monitors the status of the reference input signal (GPS)

Operates as a standby reference clock in hold-over mode if synchronisation inputs have decreased in quality or failed

Communicates by a serial port (RS-232C) with the SDR Blade for alarm reporting and equipment control.



Figure 9 – HiperMAX ATCA GPS

4.1.3 HiperMAX ATCA SDR Blade

The SDR blades' architecture is based on configurable elements, allowing implementation of a software defined radio, which ensures changes in specification can be adopted without the need to change the basic hardware construction. Using the approach based on configurable elements, the base station can be upgraded from the 802.16-2004 OFDM “Fixed WiMAX” system profile to the 802.16e-2005 OFDMA “Mobile WiMAX” system profile through the simple process of upgrading the system software. The PHY processing is implemented using picoChip technology, and the MAC is implemented within two PowerPC processors. The SDR board performs the baseband processing and frames I/Q and control signals into OBSAI RP3-01 to interface to the outdoor radio transceiver.

There are four fibre ports per SDR blade. Each transceiver is connected to one port via a fibre optic cable. Currently two OBSAI links can be active at any time; the other two links are for redundancy. There can be up to 12 SDR blades per shelf in 14-slot configuration. There is a separate power feed for each transceiver.

Figure 10 – HiperMAX ATCA SDR

4.1.4 HiperMAX ATCA Ethernet Switch

The Ethernet switch cards located in the two centre slots. It is housed on a single ATCA blade used to consolidate Ethernet traffic from all SDR blades in an ATCA chassis. This single network Gigabit Ethernet connection is then available for presentation into the backhaul equipment, or IP core network. It can also be configured such that management traffic is presented on a physically separate Ethernet port.

This solution is a platform for full redundancy switching across the ATCA backplane and removes the need for unreliable patch connections from SDRs to a separate switch. It is also managed by Netspan as an integral part of the HiperMAX base station. It is aimed at “carrier class” operators wanting a fully integrated multi-sector solution.



For smaller systems, a separate rack mount Ethernet switch can be used connected to the SDR Blades via their front panel Ethernet connections. This is a low cost alternative to the ATCA Ethernet Switch for small HiperMAX configurations and as such, has the following limitations:

Capacity Limited to support up to 3 SDRs

Not managed through Netspan

Single mains PSU only

Ethernet Patch Cables required connecting to SDR front panels (not supplied)

Not a platform for redundant configurations

4.2 HiperMAX-micro System Components

The HiperMAX-micro Base station consists of a Software Defined Radio (SDR-micro) which includes the baseband and optional GPS module within a single environmentally protected enclosure. The SDR-micro is connected to two Single Channel RF Transceivers (SCRT). The general configuration consists of:

Outdoor environmentally protected enclosure housing the Software Defined Radio (SDR), optional GPS receiver for network synchronisation and Mains PSU powering up to 2 SCRTs.

Masthead-mounted radio transceivers: single channel radio transceiver (SCRT) or future variants

External antennas, for use with SCRTs.

Optionally, GPS antenna.



Figure 11 – HiperMAX Functional Components

4.2.1 HiperMAX-micro SDR

The HiperMAX-micro Software Defined Radio (SDR) is typically designed for rooftop or pole mounted deployment. The use of separate antennas enables transmit and receive gain diversity techniques to be utilized, which increases link budget capability. The HiperMAX-micro supports both 802.16-2004 “Fixed WiMAX” system profiles for fixed and nomadic applications, as well as providing a platform for future software upgrades to support WiMAX 802.16e-2005 “Mobile WiMAX” system profiles for portable and mobile applications.

The baseband sub-system, used within the HiperMAX-micro Base station, uses the same technology as the baseband blade fitted within the HiperMAX Base station.

The HiperMAX-micro modem‟s architecture is based on configurable elements, allowing implementation of a software defined radio, which ensures changes in specification can be adopted without the need to change the basic hardware construction. Using the approach based on configurable elements, the HiperMAX-micro base station can be upgraded from the 802.16-2004 OFDM “Fixed WiMAX” system profile to the 802.16e-2005 OFDMA “Mobile WiMAX” system profile



through the simple process of upgrading the system software. The PHY processing is implemented using picoChip technology, and the MAC is implemented within two PowerPC processors.

The GPS receiver is a factory fit option and is part of the SDR-micro. It is used to synchronize Tx & Rx timing between base stations in order to avoid unwanted “hub-to-hub” interference seen with TDD systems.

Figure 12 – HiperMAX-micro SDR

4.2.2 HiperMAX-micro SCRT

The Single Channel Radio Transceiver (SCRT) consists of a Masthead RF unit and an Antenna. Usually the Antenna is mounted on the front of the SCRT, and both are mounted on a pole, alternatively the SCRT may be mounted on a plate; both the pole and plate are not provided by Airspan.

Figure 13 – HiperMAX SCRT



4.2.3 HiperMAX SCRT RF Subsystem Module

The RF subsystem contains two RF, LNA and PA modules for transmit and receive, which can provide either two individually distinguishable sectors (in a future software release) or a single sector with diversity. The RF subsystem connects directly to the baseband module. The SCRT subsystem connects to the SDR using fibre optic cable.

4.2.4 HiperMAX Antennas

In normal use the antenna is mounted on the front of the SCRT but antennas are available to mount independently of the SCRTs with short lengths of coaxial cable to connect the two. Antennas are also available, for specific bands and sector angle, which mount directly on the front of the SCRT.

For details of antennas for each frequency see the Airspan Product Catalog

The HiperMAX-micro is optimised for sector antennas. Omni antennas are not suitable when running Tx and Rx Diversity techniques in order to extend system link budget.

It is not valid to deploy a mix of vertical and horizontally polarised antennas when targeting indoor non-LOS CPE.

Vertically polarised antennas are made available only.
