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
WhereNet 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
WherePort III
WherePort III is a proximity communication device that is used to trigger a WhereTag to transmit an alternate "blink"
pattern. When a WhereTag 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 WhereTag is sending WherePort-initiated blinks, the
tag includes the identification number of the WherePort.
WhereWand Handheld Programmer
The WhereWand Handheld Programmer consists of a handheld computer with an integrated Type II PC card and an
antenna assembly. The WhereWand is capable of two-way wireless communication with WhereTag 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 WhereTag 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 WhereTag 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.
Visibility Server Software (VSS)
WhereNet'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 WhereNet Real-Time Locating System (RTLS). Visibility provides
all core software components to allow efficient 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 WhereNet, 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.
