The WB5800 Series, SensorTec’s third-generation OFDM multipoint prod- uct line in the 5GHz frequency band, represents a new class of last-mile connectivity solution for today’s large bandwidth applications. With MIMO data rates of 240 Mbps, the ST-WB5800 can serve a wide variety of bandwidth hungry applications, from transporting video traffic from a network of network video cameras to supporting enterprise connectivity. At the heart of the system is the newly designed MAC protocol optimized for efficiency and scalability in dense subscriber deployments in multipoint systems. The PPM Protocol is based on deterministic polling algorithm that will enhance the system capacity and subscriber unit count per base station. This new protocol, based on SensorTec’s successful 802.11d WiMAX product lines, is designed to provide utmost performance for carriers and enterprises. The improved RF link performance allows more flexible deployments as well. The industry-leading 400mW high-output power radio extends the coverage area for a base station, while the advanced MIMO-based OFDM technology enhances near line-of-sight connections. SensorTec’s HyperARQ protocol is designed to preserve the data throughput even at long link distances. For data security, the ST-WB5800 system incorporates 128-bit AES hardware-based encryption at full line speed, without loss of data throughput. The AES algorithm was selected to be the standard encryption method by the US National Institute of Standards and Technology (NIST). In addition, the WB5800 Series provides up to two levels of AAA protection through the configurable use of 802.1x/RADIUS and RF MAC authentication.
