The Fujitsu MB86K23 WiMAX baseband SoC is compliant with the Wave 2 IEEE 802.16e-2005 standard with optimized PHY and MAC processors for high performance. The MB86K23 is a successor to the first generation mobile WiMAX baseband IC that was certified by the WiMAX Forum.

A total WiMAX solution is available by combining related chips and supporting software:

  • MB86K52: Tri-band RF chip supports 2.3GHz, 2.5GHz and 3.5GHz bands.
  • MB39C316: Power Management IC
