RF Notice
The antenna used for this transmitter must not be co-located or operating in
conjunction with any other antenna or transmitter.
Any changes or modifications to WhereNet Corporation equipment not expressly
approved by WhereNet Corporation could void the user’s authority to operate the
equipment.
SYSTEM OVERVIEW
2.1
WhereNet RLTS System
The WhereNet real time location system (RTLS) is designed to permit users to
determine the position of tagged assets in both indoor and outdoor applications.
Each WhereTag autonomously emits a 2.4 GHz direct sequence spread spectrum
(DSSS) radio signal at predetermined blink intervals, in response to switch events,
and/or in response to WherePort devices. The signal transmitted by the WhereTag
is received by the WhereNet infrastructure which decodes that tag’s transmission,
extracts the data, and determines the tag’s location using several different
algorithms.
___________________________________________________________________________ 10
WhereWand II User’s Guide

WhereNet Confidential
D1258 rev A
___________________________________________________________________________
WhereWand II User’s Guide
The WhereNet RLTS consists of WhereTag/WhereCall tags, WherePorts,
WhereWands, Location Sensors, and the server based Visibility Suite software.
WherePorts generate a magnetic field in a localized area. WherePort devices can
be used in places where the user wants to know immediately that the tagged asset
has entered the zone covered by the WherePort field. The WhereTag devices can
be configured to blink rapidly several times when they enter a WherePort field.
When the tag blinks in response to entering a WherePort field, the ID of the
WherePort is included in the tag transmission.
WhereWands are used to configure WhereTags, WhereCalls, WherePorts, and
Location Sensors. This document will detail the operation and use of the
WhereWand.
Location Sensors receive DSSS blinks from the tags and demodulate the signal,
time stamp the blink, and send the tag ID and any associated data included in the
blink to the server over the LAN.

WhereWand II User’s Guide
The WhereWand Hand Held Programmer consists of Handheld Computer with an
external WhereWand adapter with an integral antenna assembly. The WhereWand
is capable of two-way wireless communication with WhereTag and WhereCall tag
devices. The WhereWand is also capable of wired communication with
WherePort devices. The third capability of the WhereWand is wireless
communications with the Location Sensor in the WhereNet G2 infrastructure.
The WhereWand communicates with WhereTag II/III/IV devices by sending
magnetic FSK data to the tag and receiving on-off keyed / frequency shift keyed
(OOK/FSK) RF data from the tag. The WhereWand communicates with
WhereCall and WhereTag I devices by transmitting and receiving OOK/FSK RF
data to and from the tag. Communication with the WhereTag and WhereCall
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. The
WhereWand will automatically select the proper communication protocol scheme
based on the tag’s unique identification number
ƒ
Tag IDs between 0 and 16,777,215 are WhereCall or WhereTag I
ƒ
Tag IDs between 16,777,216 and 17,099,999 are WhereTag II V2.0
ƒ
Tag IDs between 17,100,000 and 17,999,999 are WhereTag II V2.1
ƒ
Tag IDs greater than 18,000,000 are WhereTag III or IV devices
The WhereWand communicates with WherePort II or III devices using the
configuration cable included with the WhereWand. This bi-directional interface

___________________________________________________________________________
WhereWand II User’s Guide
allows the user to configure WherePort devices and read back the configuration.
WherePort configuration parameters include WherePort ID, power level, phase
setting, and tag response.
The WhereWand communicates with the Location Sensor by transmitting DSSS
messages containing the desired configuration data or test mode. This is a transmit
only operation and the Location Sensor will not transmit anything back to the
WhereWand, but the Location Sensor will flash its LEDs to indicate
communications are in progress.
2.3
Power Management
The WhereWand II’s power management is handled by the application software
installed on the handheld computer. The WhereWand II Adapter PCBA itself will
shut off the on-board high frequency RF clock while it is not transmitting to
further reduce current consumption. The WhereWand II Adapter ships with
rechargeable Lithium batteries.
Any time the WhereWand Programmer is not in use, it should be placed into its
battery charger cradle. Refer to the terminal’s Original Equipment Manufacturer
documentation included with the product.

4.2.4 Custom Configuration WherePort Retrigger
Selecting  WP Retrigger from the custom configuration screen 1 will allow
the user to set the WherePort retrigger timeout and mode. The same WherePort ID
will be ignored after causing tag blinks until the retrigger timeout expires. The
mode selects the event that starts the timer. In retrigger mode 1 (values with ‘L’
added to the time in seconds) the retrigger timer starts after the tag sends its last
WherePort blink from the previously received valid WherePort message. In
retrigger mode 2 (values with ‘E’ added to the time in seconds) the retrigger timer
will not start until the sends its last WherePort blink AND the tag has left the
WherePort field. If the same WherePort message is received before the timer
expires, the time is reloaded and the retrigger timeout starts over. In retrigger
mode 3 (values with ‘EF’ added to the time in seconds) the retrigger timer operates
the same as in mode 2, only when the timer does expire, the tag will send another
set of WherePort blinks – with the “LEFT WP FIELD” bit set. The retrigger times
can range from 1 second to 2 minutes. As soon as the user selects one of the
available timeouts, the WhereWand application will return to custom configuration
screen 1 to allow another parameter to be selected and modified. The user can
press  to move to between the WherePort retrigger pages, or  to
return to the previous menu. Anytime the tag enters the field of a different
WherePort, the blinks and retrigger from the previous WherePort are aborted and
the process begins for the new WherePort. Figure 14 shows the flow diagram of
the blinks and retrigger for one WherePort. Figure 15 shows the available
retrigger times. This configuration parameter applies only to tags with ID greater
than 17,000,000.

Table 3 outlines the WherePort to Tag range for the power levels. Since the range
is dependent on the tag orientation in the WherePort field, the table defines 3
zones. The green zone is the range at which the tag will always see the
WherePort, regardless of orientation, as it passes through the zone. The yellow
zone will typically work, but the tag may not receive the WherePort message if it
is oriented poorly in relation to the field. The red zone is an area that the tag will

The WhereWand communicates with the Location Sensor by sending DSSS blinks
containing the MAC address of the Location Sensor. The first screen the user sees
is a prompt for the Location Sensor’s MAC address. This can be manually typed in
using the WhereWand keypad, or scan from the Location Sensor bar code label
using the WhereWand laser scanner. The bar code label is located on the back of
the Location Sensor and in the site design document. Figure 42 shows the MAC
address entry screen.
Important: If the MAC does not start with 0004F1, all LS operations will result
in an error. This is a safety feature to prevent unnecessary transmissions from the
WhereWand.
Alternately, the user can enter the System Builder ID for that Location Sensor.
This will access the file LocationSensors.txt on the WhereWand to get the MAC
