DECAWAVE DW1000 PDF

Decawave's DW is the world's first single-chip wireless transceiver based on Ultra Wideband techniques. This chip enables you to develop cost-effective RTLS solutions with precise indoor and outdoor positioning to within 10 cm. This chip provides a new approach to real-time location and indoor positioning systems, location-based services, wireless sensor networks and IoT by providing accurate location awareness and communication. Based on IEEE

At Decawave we strive for customer satisfaction and so we have written a comprehensive set of application notes to assist our customers in developing their UWB products. The following application notes explain the DW expected performance and capabilities and how to optimise these during design, prototyping, and production. This application note explains how, due to the specific operation of the DW, a reflection can appear in the accumulator which looks like it has occurred before the first path.

This set of documents explains how to maximise range, why you may see issues with range or require more information on diagnostics. This application note describes different wireless sensor network architectures and how the unique strengths of the DW can complement and enhance WSN technology. This note examines some of the system-related concepts and tradeoffs that need to be considered to achieve best possible power consumption.

These guides describe the current UWB regulations per country and the certification process in key regions. This application note is also very usefull for trouble shooting your HW design. We use Cookies By using this website, you consent to our cookies policy.

This application note describes the unique strengths of the DW device and how they can complement and enhance wireless sensor network WSN technology. This application note discusses the maximum relative velocity that can exist between two DW based nodes without causing degradation in operation. This application note describes in detail how and why calibration should be used to compensate for power loss introduced by the RF path between the DW and the antenna.

Outlines the method of compensating the bandwidth and output channel power of the RF signal transmitted by the DW for variations experienced at different temperatures.

This application note describes how transmissions on different channels could cause interference. This Application note discusses how range could be improved using DW based products by the addition of a suitable low noise amplifier LNA. This application note discusses how to get most out the DW while minimizing power consumption.

This application note describes how to apply the power profile configurations showed in the datasheet. This document sets out the current situation regarding the use of UWB in all the principal geographies in the world. This document outlines the concept of certification and the certification process for UWB based products with the FCC. This application note is intended to help you to make the right choice of power source and associated circuitry for a number of typical DW applications.

This application note is a guide to select or design of the most appropriate antenna for your DWbased product.

This application notes describes the resolution of issues you might run into when porting to a 8-Bit Microprocessor.

Frequently Asked Questions

Minimising the carrier frequency offset between different DW devices improves receiver sensitivity. For more details see the section on Crystal Oscillator in the DW datasheet and for registers to use see chapter 8. In Software when using DWM, DW, the output power configuration and control can be altered by using register map register file 0x1E. For every received frame the DW receiver provides a set of frame-related diagnostic information. As there is no microprocessor on the DWM module it cannot be certified as delivered by Decawave because its mode of operation is not defined. The mode of operation is decided only when a customer connects a microprocessor and programs the module as part of their end application.
