802.11abgn/ac 1x1 + BT4.0


Quali-Fi™ RS9117 is Redpine Signals’ ultra-low-power, single spatial stream, dual-band 802.11n/ac + BT4.0 SoC. The RS9117 chipset provides low-cost CMOS integration of a multi-threaded MAC processor, baseband digital signal processing, analog front-end, crystal oscillator, calibration OTP, dual-band RF transceiver and dual-band high-power amplifiers, thus providing a cost-effective solution targeting low-power and high QoS wireless applications.

Continuing on Redpine’s tradition on low-power wireless technology and products, RS9117 is based on Redpine’s Quali-Fi technology - the industry’s first single-stream 802.11ac solution. It is tailor-made to deliver high quality wireless links to cost, power and space constrained devices under adverse RF environments. Quali-Fi leverages and improves upon Redpine’s proven low power innovations from Lite-Fi™ products and provides a future-proof 802.11ac/n and BT4.0 convergence solution for integration into smart phones and tablets. With its embedded four-threaded processor and on-chip ROM and RAM, Quali-Fi RS9117 also enables integration into zero host load applications with capability to run Wi-Fi security supplicant and TCP/IP on-chip thus setting a new benchmark for the “internet-of-things” market
