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
