What is the maximum channel bandwidth that the Fujitsu WiMAX SoC can support?
The MB87M3400 uses an OFDM (Orthogonal Frequency Division Multiplexing) PHY that supports channels from 1.75MHz up to 20MHz, and can operate in TDD or FDD modes, with support for all available channel bandwidths. A programmable frequency selection generates the sample clock for any desired bandwidth, and a 256-point Fast Fourier Transform (FFT) is used for broadband transmission. When applying 64QAM modulation in a 20MHz channel and using all 192 sub-carriers, the SoC’s data rate can go up to 75Mbps. Uplink sub-channelization is also supported.
