HiperMAX Operation

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.

A HiperMAX Base station 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.

HiperMAX supports different antenna options including:

MacroMAXe

MacroMAXe is a class-leading 2nd generation Mobile WiMAX base station which employs the software defined radio (SDR) technology first developed for HiperMAX, together with dual radio transceivers, antennas and GPS receiver all in a highly integrated, physically small and light, all outdoor package.

MacroMAXe has been designed and optimized for the 2.3GHz and 2.5GHz Mobile WiMAX bands and will be Wave 2 certified in these bands. The product has been designed to address the markets needs thru to 2011 and beyond by supporting the current and future air interfaces thanks to its SDR technology.

MacroMAXe is a remarkable base station product bringing together state-of-the-art technologies in a compact all outdoor package. Thanks to its small footprint MacroMAXe minimises site OPEX expenditure. MacroMAXe is small in size but big in performance. Thanks to the efficient power amplifier technology employed in its RF implementation, MacroMAXe implements dual 40dBm (10W) radios for 2x2MIMO delivering up to 60dBm EiRP with the integrated antennas.

MacroMAXe initially supports 5MHz and 10MHz channel sizes. However, the product is capable of supporting 20MHz channels (Mobile WiMAX profile Rel. 1.5) as well. MacroMAXe has been designed to support either 2x10MHz (using dual PHY/MAC) or 1x20MHz channel.

MacroMAXd

MacroMAXd is a WiMAX Forum™ certified base station product; one of the first to achieve certification. MacroMAXd has been shipped to customers since 2H 2005.

MacroMAXd has been 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 rollouts. It is available in the 3.4- 3.6GHz band in the 3.5F1 profile.

Each MacroMAXd sector comprises of a 4U high rack mountable shelf, which contains the baseband processor and the RF unit. The baseband is a single card that is directly connected to the RF, PA and LNA, which in turn is connected to appropriate mast installed antennas via external feeders.

Two separate antennas enable the link budget to be further increased through the use of multi-channel transmit diversity and receive diversity. A compact rack supports up to three sectors with diversity a full rack supports up to 4 sectors.

Both MacroMAXe and MacroMAXd base stations are managed by Netspan, Airspan’s SNMP based element management platform.
