The MS120 chip set from Beceem Communications supports the IEEE 802.16e Mobile WiMAX standard. The proliferation of 802.16e has the potential to extend 3G technologies in a cost-effective manner for service providers.
The chip set contains a digital baseband that includes both MAC and PHY functionality. An embedded RISC processor implements the MAC functions, thereby reducing the processing load on the host CPU. The integrated radio IC is designed for multi-band operation, as it contains multiple transmit and receive chains.
A complete reference design kit includes host driver software and RF calibration tools. The chip set is now sampling and reference designs are available. More information is available at www.beceem.com.
