Overview of Airspan’s WIMAX products

Posted on 30 March 2009 by Quantum Wimax

Airspan is a worldwide leader in broadband wireless with over 400 customers in more than 100 countries. As a founding member of the WiMAX Forum™, Airspan has led the way in WiMAX, being among the first wave of companies to achieve certification for its base station and end user premises equipment. Airspan is also leading the race to Mobile WiMAX. Through a careful choice of advance technologies, the flagship base station HiperMAX is software upgradeable to Mobile WiMAX. The recently announced MacroMAXe and MicroMAXe products also use the same baseband technology first developed for HiperMAX. The IEEE 802.16e-2005 compliant, quad-band MiMAX USB device, announced in 2006, will be the first Wave2 compatible Mobile WiMAX device for laptops.

airspan-overview

Airspan has always taken the lead to bring real-world solutions to WiMAX networks. Two examples of particular note are the seamless integration of WiMAX and Wi-Fi technologies and the introduction of VoiceMAX. Airspan’s Intel-based EasyST and ProST CPEs have versions with Wi-Fi Access Point functionality. This capability enables them to simultaneously offer both WiMAX and Wi-Fi, thus enabling the service provider to address a variety of markets including fixed, nomadic, portable and Mobile WiMAX together with any Wi-Fi enabled device. The challenges associated withdelivering time critical services such as voice and video over a shared medium such as wireless access are well known. Airspan’s VoiceMAX gives operators the ability to deliver carrier-grade VoIP through a software suite that provides admission control and manages network congestion to deliver the best user experience for VoIP calls across a HiperMAX network operating fixed, nomadic and mobile profiles simultaneously. We in Airspan believe that now is the right time to build your WiMAX networks. The advanced technologies we have embedded into our productsensure that whether you plan to start with Fixed WiMAX and migrate to Mobile WiMAX in the future or go for Mobile WiMAX from the outset, your investment is safe and your network is ready for tomorrow’s opportunities. Its industry leading technologies and solutions coupled with years of experience of building and supporting large BWA networks make Airspan the ideal partner for Mobile and Fixed WiMAX deployments.

The HiperMAX base station from Airspan

Posted on 30 March 2009 by Quantum Wimax

Airspan WiMAX HiperMAX - Base StationAirspan HiperMAX is the ultimate Mobile WiMAX base station designed for high-density deployment situations. HiperMAX has been architected to provide a highly scalable, fully redundant base station product that will continue to deliver the optimum performance for years to come.

HiperMAX is fully compatible with the Mobile WiMAX Network Reference Model (NRM) as part of the Access Service Network (ASN). HiperMAX supports the reference point (R6) between the base station and the ASN Gateway as well as the reference point (R8) between base stations. HiperMAX interworks with Airspan’s ASN Gateway called ControlMAX and with other third party ASN gateways.

HiperMAX form Airspan represents the state of the art, next generation base station design and includes:

  • Fully upgradeable, software defined, PHY and MAC layers enabling simultaneous support for both mobile WiMAX (SOFDMA) and Fixed WiMAX (OFDM)
  • Fully digital, OBSAI based, fibre optic interfaces between indoor and outdoor equipment, which can operate at up to 3km.
  • Multi-channel transmit and receive diversity
  • 2×2 and 4×2 MIMO configurations
  • 4 or 8 channel Smart Antenna Systems (SAS)
  • Support for FDD and TDD profiles HiperMAX is designed to deliver the best link budget with the highest capacity and net throughput; all essential qualities for macro-cell deployments used in typical wireless roll out.

Airspan HiperMAX implements an all-outdoor radio with up to eight-element antenna array system. All Airspan HiperMAX base stations support SAS and multi-channel Transmit and Receive diversity and are platform ready for SDMA, which uses the antenna array to enhance capacity and improve frequency re-use. HiperMax base stations cooperate with the IMS which is part of the Connectivity Service network (CSN) to deliver voice and other multimedia services and can also be configured to support VoIP applications, using a standard media gateway to the PSTN.

The flexibility of the HiperMAX architecture allows many deployment configurations including those suited to both macro and micro cellular installations. It supports all outdoor as well as split indoor / outdoor configurations allowing the operator to select the deployment model best suited to operational expense considerations and site access constraints.

wimax-equipment

A HiperMax base station from Airspan configured for traditional multi-sector macro-cell deployments consists of a baseband section, suitable for location within a protected environment, and an outdoor RF section. The indoor boards, referred to as blades within the ATCA standard, are housed in a 5 or 14 slot NEBS compliant ATCA chassis. The outdoor enclosure contains the RF subsystem components, which enables smart antenna functionality running on a Software Defined Radio (SDR). The connection between the baseband and RF sections is made through a fibre optic cable.

Airspan WiMAX HiperMAX

The antenna system of choice is connected to the outdoor RF unit and in turn to each baseband blade. HiperMAX can support up to 12 baseband blades per 14-slot shelf, with a single fibre optic cable to each RF unit. Baseband blades can be configured to support 6 active channels with full redundancy or 12 active channels without redundancy.

The ATCA shelf also houses the shelf controller and power supplies. In addition to the ATCA shelf, the HiperMAX rack houses the Ethernet switch and the GPS synchronization unit. The Ethernet switch aggregates the individual traffic streams onto a Gigabit Ethernet stream for backhaul purposes. For TDD and smart antenna operation the multiple sectors are locked to a GPS timing source. The ATCA shelf manager provides a platform management layer that holds an inventory of field replaceable units in the system and monitors their status.

Fibre optic modules operating at speeds of up to 3.1GBit/s and are connected to fibre optic cables capable of carrying up to 10Gb/s for future expansion, if required.

The all outdoor version of HiperMAX is known as HiperMAX-micro. This consists of split baseband and RF sections connected via a fibre interface, but with all power supply and GPS 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. eg. a building rooftop.

HiperMAX fully supports the extensive QoS characteristics of the IEEE 802.16e-2005 radio interface. In addition, it incorporates specific additional radio resource management features that allow applications such as VoIP to be robustly delivered by implementing Admission Control on a per call basis. HiperMAX is managed by Netspan, the SNMP based central management platform.
