Dual-band 802.11 chipset

11 July 2012 Telecoms, Datacoms, Wireless, IoT

Redpine Signals announced the release of a simultaneous dual-band 5 GHz MIMO 802.11ac + 2,4 GHz BT4.0, 802.11n chipset. 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.

The RS9333 chipset offers reconfigurable single-chip, simultaneous dual-band capability wherein it 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 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.

Form-factor reference designs for RS9333 will be available to customers in the third quarter of 2012. These are accompanied by Redpine’s field proven OneBox software framework which supports Station, AP and Wi-Fi Direct links.
