The Beceem Communications BCS200 chipset consists of a high-performance baseband IC (BCSB200) and an integrated RFIC (BCSR200) for implementing a full-featured IEEE 802.16e/WiMAX/WiBRO Wave 2 compliant mobile subscriber (MS).

The solution supports integration of dual receive chains and a single transmit chain operating in a tightly coupled manner to deliver a cost-effective, low-power SIMO (single input multiple output) and MIMO (multiple input multiple output) MS solution. The entire PHY, MAC, and RF functionality of a Mobile WiMAX terminal is implemented by this chipset.

The BCSB200 baseband IC is a highly-integrated, software programmable, multifunction digital-analog mixed-signal IC that implements IEEE 802.16e scalable OFDMA PHY and MAC functionality. Both the PHY and MAC functionality are implemented using a combination of hardware and software to achieve an optimal balance between cost, power consumption, performance and flexibility. Further, the advanced features implemented in this chip increase throughput and indoor penetration performance for both mobile and fixed applications.

The BCSR200 radio IC is a direct conversion transceiver designed for 802.16e WiMAX applications. The IC includes completely independent transmitters and receivers that cover the Broadband Wireless Access bands in 2.x GHz and 3.x GHz. The BCSR200 RFIC chip is optimized to operate with the BCSB200 baseband IC. Terminal implementations based on the BCS200 chipset are planned to interoperate with any WiMAX CertifiedT SISO or MIMO capable IEEE 802.16e/WiMAX Mobile BS (base stations).
