MicroMAX is a family of single mode (802.16d or 802.16e) highly integrated micro-cell base stations with all-in-one outdoor packaging of RF and base-band components. For Mobile WiMAX applications, MicroMAXe includes integrated dual RF transceivers to support two-channel MIMO. Performance optimized variants for high density roof-top deployments and cost optimized variants for low density / rural deployments are available.
MicroMAX family comprises of two products:
MicroMAXe is a sophisticated microcell 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.
MicroMAXe has been designed to provide a sophisticated yet costeffective base station solution in less dense deployment situations. The product supports a wide range of licensed and unlicensed frequency 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.
MicroMAXe base station product bringing together state-of-the-art technologies in a compact and all outdoor package. Thanks to its small footprint MicroMAXe is easy to deploy and minimises site OPEX expenditure.
MicroMAXe comes in two variants, a Hi-Power class and a Lo-Power class. MacroMAXe implements dual radios for 2x2 MIMO delivering up to 56 dBm EiRP with the integrated antennas.
MicroMAXe initially supports 5 MHz and 10 MHz channel sizes. However, the product is capable of supporting 20 MHz channels (Mobile WiMAX profile Rel. 1.5) as well. MicroMAXe has been designed to support either 2x10 MHz (using dual PHY/MAC) or 1x20 MHz channel.
MicroMAXe has been conceived for deployment in 3-sector configuration, which is the optimum configuration for Mobile WiMAX deployments. MicroMAXe design also incorporates an Ethernet switch which enables the traffic from 3 sectors to be aggregated for backhaul and network interfacing. MicroMAXe fully supports the interoperable R6 reference point for interworking with ASN Gateways either in a distributed or centralized network configuration.
Spectrum is a scarce and valuable resource which must be used efficiently. In order to achieve frequency reuse factor of one (N=1) the best balance between spectral efficiency and interference mitigation must be achieved. This is realised through Fractional Frequency Reuse for which MicroMAXe has been optimized. Fractional Frequency Reuse controls co-channel interference to support frequency reuse of one with minimal degradation in spectral efficiency. MicroMAXe can also be deployed using traditional frequency reuse plans.
MicroMAXd is a complete standalone base station, sharing the same system architecture as our tried and tested ASWipLL product line.
The MicroMAXd base station is highly modular in design and consists of two main components: the all-outdoor Base Station Radios (BSR) and the indoor aggregator Base StationDistribution Unit (BSDU), or the single channel Data Adaptor.
Each base station site can contain up to 16 BSRs, depending on the amount of available spectrum. Each BSR is connected to the BSDU via a 100 BaseT interface operating over a CAT5 cable, which carries both data and power. Each BSDU can support up to 8 BSRs.
MicroMAXd is designed to support lower density, rural broadband access, enterprise applications and DSL in-fill scenarios in both licensed (1.5 GHz, 3.3 GHz, 3.5, 3.7 GHz, 4.9 GHz) andunlicensed (5.1, 5.4 GHz, 5.8 GHz, 5.9 GHz) bands.
One of the key features of the MicroMAX BSR is that it requires lessthan 28W power, making it ideally suited for those rural deployments where power generation and supply may be a problem.
MicroMAXd operating in unlicensed bands can be used by Wireless ISPs to deploy WiMAX easily and cost effectively wherever the need is identified.
Both MicroMAXe and MicroMAXd base stations are managed by Netspan, Airspan’s SNMP based element management platform.
