1 INTRODUCTION
The TREK1000 is an evaluation kit that allows the user to evaluate the DecaWave DW1000
IC in an RTLS environment in different use cases.
TREK stands for Two-Way Ranging (TWR) RTLS IC Evaluation Kit.
The Evaluation Kit enables the user to evaluate the performance of the IC in 3 different use
cases:
Tracking
Geo-Fencing
Navigation
Figure 1: TREK 1000
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

•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 thereby saving power and
extending battery lifetimes
•Its ability to deal with severe multipath environments makes it ideal for highly
reflective RF environments
The Decawave DW1000 is optimized for applications in Real Time Location Systems and
Wireless Sensor Networks across a variety of markets including agriculture, building control
and automation, factory automation, healthcare, safety & security, warehousing & logistics
and a range of others.
More information can be found in the DW1000 Data Sheet and User Manual.
1.3 Use Cases & Applications
The TREK1000 can be evaluated in 3 different use cases which are applicable to real-life
industrial and consumer applications.
1. Tracking Use Case: Determine location of the Tag relative to fixed Anchors.
Examples include asset-tracking (healthcare, farming, logistics), factory automation.
2. Geo-Fencing Use Case: Determine when Tags enter or leave a specific
perimeter/zone near an Anchor. Examples include location-based payments,
personal safety (forklifts, drilling machines), child-monitoring, “secure-my-valuables”
and security bubble applications.
3. Navigation Use Case: Track the 2D or 3D location of the Tag relative to fixed
Anchors. Examples include robotics and human navigation.

3 TREK1000 HARDWARE PREPARATION AND SETUP
This section details the steps necessary to prepare the TREK1000 hardware for use.
3.1 Connect the Antenna to the EVB1000 PCB
The 4 EVB1000 PCBs come with 4 UWB (Ultra-Wideband) antennas. Each antenna must be
screwed on to the EVB1000 using the SMA connector.
It is recommended that an SMA torque wrench is used to tighten the antenna to the
EVB1000.
Note that poor connections can result in under performance in the system.
Figure 3: Connect the Antenna to the EVB1000
3.2 Mounting Option for the EVB1000 Anchors
Depending on the use case that is being evaluated, 1 or more of the EVB1000 units will be
mounted.
Figure 4: EVB1000 Mounting Options Using the Stands

The figure above shows the EVB1000 sitting in the stands that are provided in the box.
The stands could be attached to a tripod, an office partition or any other flat surface for the
stand to sit on.
It is recommended that the stand be firmly clamped into place or fixed using tape or Velcro
tape to ensure the units do not move during testing.
Figure 5: Mount EVB1000s on Tripods
When mounting the EVB1000 units do not place the antennas too close to walls or any
other objects as this can interfere with the radiation pattern of the antennas. It is
recommended that the antenna be greater than 15 cm away from the nearest object.

Page 15 of 54
When mounting the EVB1000 units on metal tripods or poles ensure that the top of the poles
are below the ground plane of the antennas. The ground plane of the antenna is considered
to be the top of the SMA connector under the antenna.
Figure 7: Keep Metal Objects below the Antenna
3.3 Powering the EVB1000
The EVB1000 can be powered either via an external DC power supply (or battery) through
jumper J7 on the back of the EVB1000 using the supplied power cable leads or via a
standard 5 V 500 mA USB power supply through jumper J5. To change between the two,
jumper J8 is used as shown in the figure below.

In this mode the externally applied supply is indirectly
connected to the on-board circuitry through an LDO
regulator
Changes to jumper settings should only be made with the board powered down –
under no circumstances should jumper settings be changed while power is applied to
the board via any of the possible off-board connectors, or damage to the board may
result.
For the two power source options the positions of the jumpers are shown in Figure 9.
Jumpers J2 and J3 can be used to select whether sections of DW1000 are powered with 1.8
V or 3.3 V, for more details on this operation see Reference [1].

Also, each EVB1000 unit can be configured as either an Anchor or a Tag.
The configuration for each unit is set using the TREK configuration DIP switches (S1) on the
PCB.

The TREK configuration DIP Switches can be found on the front of the EVB1000 unit above
the display.
3.5 EVB1000 Display
When the EVB1000 is powered up there is a start-up screen appears containing the version
of DecaRangeRTLS ARM software that is running on the microprocessor.

After about 20 s the display changes to show the current operating mode and the
configuration as Anchor or Tag.

Once the Tag and Anchors start communicating (two-way ranging) the Anchor-to-Tag
measured distances appears on the display. The display will cycle through the distances
from the unit with the display to the other units.

4 ARRANGEMENTS FOR DIFFERENT USE CASES
This section shows the arrangement of the EVB1000 units when evaluating the 3 different
topologies:
1. Tracking Use Case
2. Geo-Fencing Use Case
3. Navigation Use Case
4.1 Tracking Use Case
For evaluating the tracking use case the system is configured as:
3 Anchors
1 Tag
In this case example below: Channel 2, 110 kbps is selected as the operating mode.
The 3 Anchors are configured as shown below.
Figure 15: Tracking Use Case: Example Anchor Settings
The Tag is configured as shown below.
