FMA introduces its integrated WiMAX system-on-chip, MB87M3400, which complies with the 802.16-2004 standard. The MB87M3400 is designed to enable deployment of BWA equipment for both basestations and subscriber stations in licensed or license-exempt bands of 2 to 11 GHz. The SoC uses an OFDM (Orthogonal Frequency Division Multiplexing) PHY that supports channels from 1.75 up to 20 MHz, 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 64-QAM modulation in a 20 MHz channel and using all 192 sub-carriers, the SoC can sustain raw peak data speeds up to 100 Mb/s. Uplink sub-channelization is also supported.
