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.

Mobile WiMAX Chipsets

The WiMAX standard enables system vendors to create many different types of WiMAX-based products, including indoor and outdoor CPEs, as well as mobile handsets in the forms similar to the traditional cell phones. To address the increasing demands of attractive Mobile WiMAX handsets, and foreseeing the difficulty of including WiMAX into an already complicated mobile handset design, Fujitsu now introduces its 2nd generation chipset target to enable module vendors to modulize hardware components that are necessary for a Mobile WiMAX handset, into an easy and concise single package.
The chipset includes a baseband LSI, the MB86K22; an RF LSI, the MB86K52; and a power management LSI, the MB39C316.
