Fujitsu to Demonstrate WiMAX with Adaptive Beamforming at Mobile World Congress 2009

Fujitsu and Cisco will team up at this year’s Mobile World Congress to show a multi-application interoperable demo including video streaming by using mobile WiMAX with adaptive beamforming and multiple input/multiple output (MIMO) capabilities.

The demonstration will use Cisco's BWX8305 WiMAX base-station and Fujitsu's mobile WiMAX USB terminal featuring multiple video streaming and FTP files, which will be wirelessly transferred between the Cisco base-station and the Fujitsu USB dongle.

Fujitsu’s mobile WiMAX USB terminal is based on the Fujitsu mobile WiMAX chipset. The chipset includes the Fujitsu MB86K21, a MAC and PHY mixed signal baseband SoC, and the MB86K71 RF module, incorporating an RF-IC, antenna switches, a power amplifier, filters and an oscillator circuit. Fujitsu’s mobile WiMAX reference design has been certified by the WiMAX Forum.

Fujitsu and Cisco have been investigating a wide range of WiMAX technologies beyond the usual specified certification during their interoperability testing. This collaborative effort came as a result of a jointly signed IOT agreement. The interoperability demonstration with Cisco showcases how adaptive beamforming with MIMO technology is implemented in a mobile WiMAX (802.16e-2005) network. It is estimated that smart WiMAX systems will double the system capacity, while offering up to twice the coverage of simple WiMAX networks in a fully mobile setting.

Fujitsu and Cisco are about to undertake interoperability tests on a Mobile Internet Device (MID) based on Fujitsu’s new WiMAX module and Cisco’s base-station. Fujitsu’s second-generation mobile WiMAX module consists of the MB86K22 baseband IC, power management IC and tri-band RF IC, and is optimised for embedded use. Fujitsu’s low power process technology coupled with its power gating scheme greatly reduce the power consumption by 70% when compared to the first-generation baseband chip.
