1 INTRODUCTION

1.1 System overview

The ZES Real Time Locating System (RTLS) is designed to permit users to determine the position

of tagged assets in both indoor and outdoor facilities such as factories and freight yards. The system

locates tagged assets by a process involving redundant triangulation. Each tag autonomously emits

a 2.4 GHz direct sequence spread spectrum (DSSS) radio signal at predetermined blink rate. Each

tag’s blink rate is randomized around its predetermined value to minimize the number of collisions

between transmissions made by different tags. The signal emitted by the tag is received by a

minimum of four Location Antennas. A typical transmission contains a preamble which is used to

synchronize the receiver, the tag’s serial number which identifies the tag, a status word which

monitors various tag functions, data stored in the tag’s memory and finally a CRC used to assure

that the tag’s message is correct as received.

The principal components of ZES’s RTLS are shown in Figure 1.

1.2 WhereTag IV Module

The WhereTag IV Module is a compact battery powered radio frequency device which is used in

WhereTag IV, WhereCall III+ and WhereCall IV tag products. These tag products are key

components of the ZES Real Time Locating System (RTLS). The tags can be attached to assets of

many kinds, such as forklifts, containers, ULDs, hospital and test equipment as well as trailers and

container chassis's. It is used to manage those assets by allowing them to be identified and located

by the system.

The WhereTag IV Module "blinks" an RF transmission at pre-programmed rates ranging from 1

second to 5 days between blinks. The ZES RTLS infrastructure receives these blinks and use

sophisticated Differential Time of Arrival, (DTOA), algorithms to determine the location of the tag.

Accuracy of this determined location can be as low as 2 meters and is nominally within 3 meters in

most installations. The WhereTag IV Module complies with the ISO 24730-2 RTLS standard. It

____________________________________________________________________________________________ 8

User Guide for WhereTag IV Module D1587 Rev 01

operates in the globally accepted 2.4GHz frequency band and transmits spread spectrum signals in

accordance with the standard. The use of direct sequence spread spectrum technology provides

extremely long range; in excess of 1,000 meter locate range outdoors, and 120 meter locate range

indoors. The WhereTag IV Module also incorporates an 802.11b/g transceiver for data

communication and/or positioning by standard or location-enabling 802.11 access points. The

combination of low average power consumption and good engineering allow the WhereTag IV

Module to operate for long periods of time without any maintenance. Battery life can be as long as 6

years when connected to a AA lithium battery. A magnetic receiver is also built into the WhereTag

IV Module. The module can receive low frequency magnetic signals from an exciter called a

WherePort. The WherePort transmissions can be read at distances ranging from 1 to 8 meters.

Each WhereTag IV Module has a unique identification number that is transmitted via radio during

each blink. WhereTag IV Modules are configured with ZES’s WhereWand.

1.3 WhereLan Location Sensor (LOS) and Location Access Point (LAP)

The Location Sensor and Locating Access Point receive the tag transmissions and forwards the

information to the ZES Visibility Server Software which performs locations calculations, database

functions and systems management. The Location Sensors and Locating Access Points

communicate with each other and the Visibility Server Software via standard wired Ethernet cables

or an 802.11b-compliant wireless LAN. Utilizing sophisticated DSP technology, the LOS and LAP

____________________________________________________________________________________________ 10

are able to track large populations of WhereTags simultaneously. They can be installed in a grid

configuration to provide ubiquitous coverage over large areas comprised of many cells. The

Locating Access Point combines multiple functions: an RTLS Location Sensor and a Wi-Fi certified

access point for wireless LAN clients and applications

1.4 WherePort III and WherePort IV

WherePort III and WherePort IV are proximity communication devices that are used to trigger a

WhereTag IV Module to transmit an alternate "blink" pattern. When a tag passes though the

WherePort's field, the tag can initiate a pre-programmed and (typically) faster blink rate to allow

more location points as a tagged asset passes through a critical threshold, such as a

shipping/receiving dock door or from one zone to another. When the tag is sending WherePort-

initiated blinks, the tag includes the identification number of the WherePort.

1.5 WhereWand II Programmer

The WhereWand II Handheld Programmer consists of a handheld computer connected to a palm-

size box radio frequency device. The WhereWand is capable of two-way wireless communication

with tag devices. The WhereWand is also capable of wired communication with WherePort devices.

The third capability of the WhereWand is wireless communications with the WhereLan. The

WhereWand communicates with tag devices by sending magnetic FSK data to the tag and receiving

on-off keyed / frequency shift keyed (OOK/FSK) RF data from the tag. Communication with the tag

allow the user to set tag configuration parameters such as DSSS blink intervals and tag responses

to such stimuli as WherePorts and/or switch/telemetry inputs. It also allows the user to read back

configuration and other data from the tag.

1.6 Visibility Server Software (VSS)

ZES's Visibility Server Software (VSS) is an integrated software package that provides all

the tools required to effectively manage assets and resources as well as the ZES Real-Time

Locating System (RTLS). Visibility provides all core software components to allow efficient

____________________________________________________________________________________________ 11

User Guide for WhereTag IV Module D1587 Rev 01

resource management. Key among those software components is WhereSoft Locate, which

is a distributed Windows Service. When WhereSoft Locate is combined with Visibility and

any of the many applications available from ZES, it is possible to locate assets, know their

status, and react to any number of user configurable alert conditions. Visibility also provides

the tools required to control and monitor the Real-Time Location System (RTLS). It includes

configuration tools, diagnostics, system alerts, an interface manager and installation tools.
