The algorithm allows any Wi-Fi-connected embedded device to detect the presence of humans, estimate their motion, approximate their location, and sense subtle gestures and movements, like breathing.
Synaptics Incorporated has announced the launch of the SYN43711, a system-on-chip expanding its wireless connectivity solutions for the Internet of Things (IoT). It is a Wi-Fi 6E and Bluetooth 5.3 combo SoC designed for high-performance applications in consumer, industrial, and enterprise systems.
Innovative features of the SYN43711 include Wi-Fi sensing, which uses proprietary algorithms to analyse channel state information (CSI). This allows Wi-Fi-connected devices to detect human presence, motion, location, and subtle gestures or movements.
Capable of operating on both 2.4 GHz and 5 or 6 GHz bands simultaneously, the device provides up to 600 Mbps throughput. It adheres to the IEEE 802.11ax standard and supports Bluetooth 5.3 with low energy (LE) audio, enabling multiple concurrent Bluetooth connections and audio streams, including AuracastTM. Supporting Bluetooth low energy (BLE) and BLE channel sounding it aids in high-accuracy distance measurement (HADM).
It features optimised Wi-Fi/Bluetooth radio coexistence capabilities in the 2.4 GHz band using Synaptics Smart Co-Ex technology. The chip’s shared Wi-Fi and Bluetooth receive signal path eliminates the need for an external RF switch while maintaining high sensitivity.
It includes integrated power amplifiers (PAs) and low noise amplifiers (LNAs), with options for external PAs and LNAs to achieve the highest levels of transmit (Tx) power and receive (Rx) sensitivity. Its high integration significantly minimises the device’s physical footprint, cost, power requirements, and complexity, while also accelerating time-to-market.
It can be integrated into premium home appliances and finds applications in multimedia streaming in smart home environments and wireless home security cameras. It is useful in drones, robots for enhanced connectivity. It enhances automotive infotainment systems with its robust connectivity. The device fits the demands of smart factories and Industry 4.0 with its advanced features.
The device is compact in design (5.41mm x 4.24 mm x 0.51mm) and is available in two packages: standard and plated-through-hole (PTH). Synaptics is currently sampling the SYN43711 to key customers, with production quantities expected to be available in Q1, 2024.
