1.1 RTLS
Real-Time Location Systems (RTLS) are used across many industrial segments e.g. factory
automation, warehouse logistics, building automation, healthcare, sports.
Existing solutions (e.g. Wi-Fi, BLE, ZigBee) suffer from inaccurate location estimations, high
power consumption (short battery life) and costly installations & maintenance.
Decawave provides solutions to these issues by using UWB (Ultra-Wideband) technology in
a single IC. UWB-based RTLS use highly reliable time-based measurements to outperform
existing solutions in terms of accuracy, reliability and cost.
Decawave supplies key RTLS enabling blocks:
UWB IC for time-of-arrival (TOA) estimation
2D&3D location solver algorithm using Two-Way Ranging (TWR)
Source code examples for driving the ARM microprocessor and User Interface (UI)
used in TREK
1.2 Decawave DW1000 IC
The DW1000 is a fully integrated low power, single chip CMOS radio transceiver IC
compliant with the IEEE 802.15.4-2011 ultra-wideband (UWB) standard.
•
It facilitates proximity detection (1-D) to an accuracy of +/- 10 cm using two-way
ranging time-of-flight (TOF) measurements.
•
It facilitates real time location (2-D or 3-D) of assets to an accuracy of +/- 30 cm in
x and y (and z) using either two-way ranging (TOF) measurements or one-way
time difference of arrival (TDOA) schemes
