The RS9333 chipset uses Redpine’s Quali-Fi 802.11ac technology and ThreadArch multi-threaded processor to achieve 1.3 Gbps on-air throughput at a form-factor and power-consumption that enables integration into smartphones and tablets.
The new SoC is based on Redpine’s Quali-Fi 802.11ac technology. It offers PHY data throughputs up to 1.3 Gbps 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 5 GHz or simultaneous 2x2 11ac in 5 GHz and 1x1 802.11n in 2.4 GHz. In addition, the RS9333 chipset supports BT4.0 in 2.4 GHz which coexists optimally with the on-chip 802.11n/ac using innovative coexistence mechanisms.
Based on Redpine’s 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 2.4 GHz spectrum and into the 5 GHz band. Concurrent dual-band support enables 802.11ac to meet next-generation requirements while providing backward compatibility with legacy 2.4 GHz networks," said Linley Gwennap, Principal Analyst of The Linley Group.
“Concurrent dualband is synonymous with large costs and high-power today and is limited to high-end routers. This is mainly due to the usage of two separate baseband chips one each for 2.4 and 5 GHz and the associated costs of a high-end network processor. With Quali-Fi RS9333 Redpine is spearheading the integration of concurrent dualband into power, form-factor and cost-sensitive products like Smartphones, tablets and ultra-books,” said Venkat Mattela, CEO of Redpine Signals. “Based
