概述
描述
Renesas' Wireless Ranging (WiRa™) Software Development Kit (SDK) enhances the DA1469x family of Bluetooth® Low Energy (LE) System on Chip (SoCs) with highly accurate and reliable distance measurement capabilities. Current market offerings fall short due to the radio signal strength indicator (RSSI), a flawed measure that is sensitive to radio signal blockages. Unlike RSSI, the WiRa™ SDK uses a radar-like implementation to greatly enhance distance measurement for connected devices, amounting to +/- 0.5 meters in typical situations. The result is a solution with 10x the accuracy of competing RSSI-based localization options.
The WiRa™ SDK uses phase-based ranging technology and advanced signal processing to provide reliable distance measurements between connected devices. Built on the DA1469x wireless MCU family, it integrates distance measurement and Bluetooth® LE connectivity into a single-chip solution, including a Bluetooth LE 5.1-compliant stack and software implementation, while ensuring coexistence between Bluetooth communications and the distance measurement process.
This all adds up to a solution that provides end-users with greater reliability, security, and location and tracking accuracy for the IoT devices in peer-to-peer applications.
