WiMAX Base Station: Providing broadband wireless access
WiMAX Base Station is the center piece of the Wireless Access Service Network. On the radio side, it interfaces with WiMAX terminals via the R1 interface. On the backhaul side, it interfaces with WiMAX ASN-GW via the standard R6 interface.
A WiMAX Base Station consists of Physical layer (PHY), Multiple Access Control Layer (MAC) and Network Control and Management System. The PHY layer provides mechanisms for Base Station and Terminals to exchange information over the air. These mechanisms include advanced channel encoder and multiple antennas transmission techniques. With these mechanisms, the PHY of WiMAX is able to transmit data over a long distance and achieve high data rate in limited channel bandwidth.
The MAC layer improves the link robustness and allocates channel bandwidth to multiple terminals. WiMAX terminals having applications such as video conferencing and web browsing would have very different requirements on system throughput and latency. The MAC allocates channel bandwidth to terminals according to their QoS requirements.
ASTRI's mobile WiMAX base station platform is integrated with high performance MPU, DSP, FPGA, Mixed-Signal and RF to provide a complete solution with high processing power and performance. It is suitable for current and future advance wireless technology development. This highly flexible platform allows the dynamic and application-oriented hardware optimization in cost, form factor and power reduction. The PHY and MAC of WiMAX Base Station are implemented with this platform.
