Mobile WiMAX Solutions
The Fujitsu MB86K21 WiMAX SoC is a cost-effective, fully integrated MAC and PHY mixed-signal baseband processor for WiMAX
Mobile Stations. Fujitsu's WiMAX SoC is compliant with IEEE 802.16e-2005 targeted to be the first in its class to participate
in WiMAX Forum Wave 2 certification. The RF module, MB86K71, includes RF-IC, antenna switches, a power amplifier, filters,
and an oscillator circuit. This RF module supports MIMO(*) technology, thereby enabling high-speed and reliable wireless connections that are essential for Mobile WiMAX devices. Furthermore,
Fujitsu also has verified that this RF module can be connected to the baseband chip, MB86K21.
Fujitsu offers a system solution based on the accumulated knowledge of WiMAX technologies and the full experience of the baseband
development and mass production of 2G and 3G mobile handsets. The MAC and PHY for mobile WiMAX SoC are optimized for use in
mobile stations and terminals, PC cards and other media-rich handheld devices, and are assured of meeting carrier-class requirements.
(*) MIMO: Multiple Input Multiple Output. A technology that uses multiple antennas at both the transmitter and receiver to improve
high-speed communication performance.
