Redpine Signals has developed the industry’s first dual-band WiFi chip to handle both 5GHz MIMO 802.11ac and 2.4GHz BT4.0, 802.11n simultaneously to give flexibility to industrial designs.
Page 1 of 2The RS9333 chipset uses Redpines Quali-Fi 802.11ac technology and ThreadArch multi-threaded processor to achieve 1.3Gbps on-air throughput at a form-factor and power-consumption that enables integration into smartphones and tablets.
The new SoC is based on Redpines Quali-Fi 802.11ac technology. It offers PHY data throughputs up to 1.3Gbps and an advanced 802.11ac feature set encompassing Multi-User MIMO and LDPC. It has a unique reconfigurable single-chip simultaneous dual-band capability where the chipset can be configured on-the-fly through software as either a 3x3 802.11ac solution in 5GHz or simultaneous 2x2 11ac in 5GHz and 1x1 802.11n in 2.4GHz. In addition, the RS9333 chipset supports BT4.0 in 2.4GHz which coexists optimally with the on-chip 802.11n/ac using innovative coexistence mechanisms.
Based on Redpines in-house four-threaded processor ThreadArch, the RS9333 achieves high-throughputs and real-time QoS on the concurrently operational 802.11ac, 802.11n and BT4.0 wireless links while still keeping a free hardware thread available for offload of Layer-3 and application-specific functions. The chipset provides PCI-e, USB and SDIO3.0 host-interfaces to enable integration into a multitude of systems ranging from smartphones and tablets to high-end enterprise routers.
"Cloud-based services and multimedia streaming are increasing the demand for wireless bandwidth and QoS. These demands are pushing next-generation Wi-Fi 802.11ac out of the crowded 2.4GHz spectrum and into the 5GHz band. Concurrent dual-band support enables 802.11ac to meet next-generation requirements while providing backward compatibility with legacy 2.4GHz networks," said Linley Gwennap, Principal Analyst of The Linley Group.
