June 2001 TFF-1015-00AB_UserMan_02_23_04.doc Page 4 Introduction System overview The WhereNet 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 WhereNet’s RTLS are shown in Figure 1. WhereTag III Device The WhereTag III is the same as the existing WhereTag II with the exception that it has a 200 mW RF power amplifier added to boost the RF ASIC’s power output from 2 mW to 60mW. The WhereTag III is the first level component of the WhereNet Real Time Locating System (RTLS). It is a low-cost wireless device that attaches to a resource (such as an asset, pallet, container, vehicle, etc.) and periodically broadcasts, via radio, it’s unique identification number. WhereNet’s RTLS infrastructure detects that signal and precisely locates the tag and it’s associated resource. Powered by a long-life internal battery, the WhereTag III’s beacon signal can be configured to “blink” from every half second to once an hour. This allows some resources to be tracked second to second while others that are less mobile can be tracked less frequently. At a typical blink rate of four minutes, the tag’s battery can last six years. When excited by a WhereNet WherePort, a WhereTag III can alter its blink rate (typically faster) to enable more timely location updates for critical threshold zones such as shipping/receiving docks and other portals. Each WhereTag III has a unique identification number that is transmitted via radio during each blink. When it’s battery is running low, the tag alerts the WhereNet RTLS infrastructure so that the tag can be proactively replaced. WhereTag IIIs can be pre-programmed with 12 bytes of supplementary data (such as an asset or serial number) that can be included with each blink. WhereTag IIIs are configured with WhereNet’s WhereWand. The number is also printed as a Code 128 bar code on the tag. The bar code enables seamless integration with existing inventory systems and delivers a cost effective total resource visibility solution that extends beyond the range of the WhereNet Location Antennas. WhereTags are extremely durable and can be used both indoors and outdoors. The tag’s case is resistant to oils, solvents and hydraulic fluids. WhereNet Location Antenna This device is an active antenna that mounts remotely and is connected to the Location Processor. Its function is to receive spread spectrum radio signals from the WhereTag devices. It converts the radio frequency signal to a lower intermediate frequency and transfers those signals to the reader processor cards in the Location Processor.

The Location Processor is able to track a large number of WhereTag devices simultaneously to assure location accuracy over a large coverage area. The Location Processor forwards accurate location information, in real-time, to the WhereNet server, where information can be graphically displayed, used for report generation or accessed through the Internet. WhereNet Hand-Held Communicator or WhereWand These devices allow the users to reconfigure the blink rate and 12 bytes of memory in a WhereTag.

Prior to installing a tag on an item to be tracked, the tag must be activated. This is done using the WhereNet’s WhereWand. The WhereWand is used to configure and activate the tag, and to confirm that the tag is properly configured and operational. The detailed procedure for tag activation is covered in WhereWand User’s Manual. Tag Mounting Options Introduction The WhereTag III device has a variety of ways to be mounted depending on the user’s needs.
