It includes everything needed to be able to configure the tag and the communications between the tag and a host system. Appendix A is a complete description of all the WhereTag commands together with examples of how they are used to set up and operate the WhereTag. Appendix B is a physical description of the tag. This chapter briefly describes the major features and components of the Real Time Location System. The Real Time Location System The WhereNet system tracks and locates items tagged with a WhereTag. Each tag emits short, low power bursts of widely spread spectrum radio energy. These bursts are received by the system infrastructure. The infrastructure calculates the location of the tagged item based on the different arrival times of the burst. The WhereTag III HO or ST is a compact battery operated radio frequency device. It is a component of the WhereNet Real Time Location System. The WhereNet Real Time Locating System (RTLS) is a precise local locating system with robust wireless telemetry capabilities. Its integrated architecture meets all the requirements for an enterprise-wide wireless infrastructure including locating, telemetry, and high-speed wireless communications. WhereTags WhereTags are attached to assets whose status must be quickly and accurately monitored. Examples are the movement of a shipping container through a loading yard or a trailer through a warehousing facility. RTLS uses DSSS RF technology to determine the location of WhereTag transmitting beacons. These transmissions are extremely low power, about 2 mW (high output options increase this to 54 mW). The transmissions can be received at distances in excess of 1,000 meters outdoors (high output tags operate at up to 3,000 meters). Because the transmissions are low power and spread across 60 MHz they add almost no RF pollution to the environment. They can be readily used with wireless LANs and Blue Tooth devices without adversely affecting the throughput of those systems. The transmissions from the WhereTags are very resistant to interference because of the large amount of processing gain. The system is able to receive signals that are below the RF noise floor of the surrounding environment. WhereTags are located by measuring the difference in the arrival time of a signal at a minimum of three fixed-position Location Sensors (the reliability increases if more than three sensors receive the signal). The WhereTags transmit their keep alive signal at a programmable interval. The Location Sensors are in a grid formation that ensures that at least three antennas can receive a blink from any place within the site. By comparing the difference in the arrival time of the beacon signal at each of the receiving antennas the system can determine the location of the transmitting WhereTag. This type of location determination is called TDOA (Time Difference Of Arrival). Tags are located to an accuracy of less than ten feet in virtually all environments, indoors and out. The accuracy can be affected by environmental factors such as concentrations of large metal objects. Location Sensors The Location Sensors are interconnected using standard Ethernet or connected wirelessly using 802.11b/g WiFi compliant communications. One type of Location Sensor, called a Locating Access Point, (LAP) includes a full 802.11b/g Access Point (AP). These integrated APs are from manufacturers such as Cisco, Symbol, and Intermec.

All the wireless services required within an enterprise are then available on a single infrastructure. WherePorts The WherePort transmits a short range, adjustable from 5 to 20 feet, 127 kHz electro-magnetic signal. This signal defines a field. The field may indicate an entry gate or transition point. Each WherePort is programmed with its own ID. When a tag receive a WherePort trigger it transmits the WherePort ID along with its own ID to the location server. The server then knows that the tagged object has entered the gate or completed a transition. Because the location of the WherePorts is known, the server can locate the tag according to the WherePort field even if the tag can not be located on the full X-Y coordinate grid of the location sensors. Communication The WhereTag has multiple types of transmissions, keep alive blinks, switch blinks, and WherePort/data blinks. The keep alive blink is controlled by the WhereTag and blinks at the programmed interval. Switch blinks and WherePort/data blinks are triggered by activity on a switch, a WherePort field, or a telemetry request from the host. There are three formats for messages, short, medium, and long. The shortest one identifies the WhereTag and is used for location processing. The longest transmission can include 88 bits of telemetry information. When connected to a host microprocessor, additional information about the tagged item and its status can be transmitted. The WhereNet system is scalable. A single Location Sensor and server can detect the presence of a WhereTag within its 1,000 meter outdoor range. In addition, it can receive telemetry data, such as vehicle VINs, fuel status, and mileage from WhereTag equipped vehicles. Or hundreds of Location Sensors can be interconnected to cover a site of hundreds of acres and provide accurate X-Y coordinates for tracked assets on a map of the site.
