802.16e Mobile WiMAX™

To continue the progression from fixed to mobile, Fujitsu has developed a one-chip, highly integrated, MAC and PHY, mixed signal, baseband processor for Mobile WiMAX™ applications.

Mobile WiMAX system on chip

The MB86K21 baseband SoC is designed to optimise power consumption using Fujitsu’s 90nm with low-leakage process technology. It uses Fujitsu’s capability to integrate complex electronic devices, its extensive experience in mobile phone design and development, and its system knowledge and expertise for end-to-end WiMAX solutions.

The Fujitsu WiMAX SoC is fully compliant with the IEEE 802.16e-2005 Mobile WiMAX standard.
