Asset and People Tracking

 

 

Introduction

Asset and people tracking has been evolving over the past 2 decades, from simple barcodes and QR Codes to RFID tags/badges offering ‘passive’ tracking capabilities to more recently include Bluetooth LE ‘active’ tracking. Bluetooth ‘active’ tags can offer a number of key benefits including: remote reading using smartphones (user does not need to physically locate a tag or be close to it and they do not need expensive hand-held readers eg RFID readers), it can also measure and track information (active) about the asset or person instead of just reporting its identity (passive) and communicate this information on request (data can be very useful in determining when/where/what events, including environment, movement, location, proximity) and Bluetooth LE tags are more able (compared to RFID tags) to be read through liquids making them better suited to cold-chain tracking of pharmaceutical goods or liquid consumer goods (such as Inkjet cartridges, wines/spirits, etc).

Dialog’s Bluetooth LE portfolio includes SOCs well suited to both asset tracking (pallet, box and even item level) and people tracking (basic badges through to high-content UI wearables.

Wireless System-on-Chip (SoC): The SmartBond™ DA1469x family of Bluetooth® low energy solutions is Dialog’s most advanced, feature rich range of multi-core microcontroller units for wireless connectivity. Offering the highest integration, processing power and RAM and customizable radio RF to support a broad range of applications.

Wireless Ranging (WiRa™) SDK: Dialog's WiRa technology offers fine-grain, phase-based ranging performance approaching UWB (ultra-wideband) accuracy, while using significantly lower power (extending battery life) and lower solution cost. It enhances the DA1469x family of Bluetooth LE SoCs with new, highly accurate and reliable distance measurement capabilities.

Memory: SPI NOR Flash Memory is a perfect match to the Bluetooth low energy engine, featuring ultra-deep power down for battery powered designs.

GreenPAK: Dialog’s GreenPAK Mixed-signal Matrix ICs integrate many system functions to minimize components, reduce PCB space, and reduce power. With the straightforward, free GreenPAK Designer software an engineer can develop a unique solution for their product without standardized discrete circuitry or firmware.

Overview

 

  Description Benefits
WiRa The WiRa™ SDK leverages the existing DA1469x wireless MCU family – including its ARM® Cortex®-M33 application processor, M0+-based baseband processor and best-in-class radio performance – to provide distance measurements from a single chip. It also comes equipped with a Bluetooth LE 5.2 compliant stack and software implementation, eliminating the need for hardware adaptations or an external host processor and ensuring co-existence between Bluetooth communications and the distance measurement process.

Add distance measurement as a feature to your Bluetooth or Proprietary wireless applications

Improved accuracy and robustness compared to RSSI based localization

No additional HW needed compared to standard Bluetooth LE system designs

Single-chip embedded system architecture
