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

____________________________________________________________________________________________ 7

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

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 WherePortinitiated 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 palmsize 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

____________________________________________________________________________________________ 10

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.
