General Description
The Wise Infant tag emits beacons at an interval configured during pairing Infant Tag that enables
the ultra-low-power connectivity and basic data transfer for applications previously limited by the
power consumption, size constraints and complexity of other wireless standards. Infant tag is
basically used in
tracking system. Also
Infant tag is powered with CR1225 battery were it
considerably reduced power consumption and compact in size.

Antenna
WiSe Infant tag has the external Flex PCB printed antenna .The WiSe infant tag has been certified
with the external antenna only.
The external antenna’s directivity determines the required position. We need to make sure the
external antenna impedance is close to 50 Ohm to have optimal matching. External antenna’s center
band frequency should be in the range of 2.4 to 2.402 GHz. The PCB antenna employs a topology
that is compact and highly efficient.

Operation of the WiSe Infant Tag:
The Wise Beacon tag emits beacons at an interval configured during pairing via Wise Tracking
Application.
The tag has an LED which indicates the state of the tag.
Initially tag is powered off – LED is not lit.
Tag is powered on by pressing the button for at least 2 sec and will be in pairing mode for 30
sec (duration is configurable) – LED will blink every 500ms.
After pairing mode, if tag is not paired, it will power off. If the tag is paired, normal
operation of tag is initiated - beacon packets will be transmitted at the configured interval –
LED will not be lit.
During normal operation, tag may be powered down by pressing button for 30 sec – LED will
blink thrice and turn off.
During normal operation, if button is pressed for at least 1 sec – LED will blink once

Warning:
Changes or modifications not expressly approved by the party responsible for compliance could void
the user's authority to operate the equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions:
1) This device may not cause harmful interference, and
2) This device must accept any interference received, including interference that may cause
undesired operation.
NOTE: This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates uses and can radiate radio
frequency energy and, if not installed and used in accordance with the instructions,
may cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If this
equipment does cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user is encouraged to
try to correct the interference by one or more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
-Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
-Consult the dealer or an experienced radio/TV technician for help
