1 Introduction
1.1 About the DW1000
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 to an accuracy of +/- 10 cm using two-way ranging time-of-flight (TOF)
measurements.
•
It facilitates real time location of assets in to an accuracy of +/- 10 cm using either two-way ranging (TOF)
measurements or one-way time difference of arrival (TDOA) Time Difference of Arrival schemes
•
It spans 6 RF bands from 3.5 GHz to 6.5 GHz
•
It supports data rates of 110 kbps, 850 kbps and 6.8 Mbps
•
Its high data rates allow it to keep on-air time short and thereby save power and extend battery lifetimes
•
Its ability to deal with severe multipath environments makes it ideal for highly reflective RF
environments
