1. Introduction
omlox WTag is part of BeSpoon RTLS, a real-time locating system which uses
Ultra-Wideband (UWB) pulses for real-time 3D location of objects in buildings in
various industries.
omlox WTags are mainly used as mobile devices while omlox Satellites are
used as fixed bases in BeSpoon RTLS. In this case, the omlox Satellites are syn-
chronized with eachother. The mobile devices, such as omlox WTags or omlox
SmartAntennas are tracked in two modes which can coexist: Multi-Tag Tracking
(server-centric) and GPS-like Positioning (device-centric).
omlox WTags may also be provided as part of special mobile kits without omlox
Satellites and without server. In this case, BeSpoon RTLS works in a particular
device-centric mode, called Single Self-Positioning: only 1 omlox mobile
device is tracked, the others are used as fixed bases (then, unlike in the main
configuration, the fixed bases are not synchronized).

This document includes regulatory information, as well as a detailed hardware
specification and a description of its features.
For detailed features and user instructions regarding the complete system,
please refer to the BeSpoon RTLS documentation included in the RTLS
DELIVERY Pack. The RTLS DELIVERY Pack includes documentation and the
related software toolchain, to make the development processes easier. It
contents evolves according to BeSpoon RTLS developments.

2. Safety and compliance information
2.1. General
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 anyinterference received, including interference
that may cause undesired operation.
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 in-
terference 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 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.
CAUTION
•BeSpoon RTLS equipments are configured to cover only the area inside
buildings, preventing omlox WTags and other UWB devices of the system
from emitting UWB signals outdoors.
Contact your system administrator if you are unsure as to the extent of
coverage.
•This equipment may only be operated indoors.
Operation outdoors is in violation of 47 U.S.C. 301 and could subject the
operator to serious legal penalties.
•UWB devices may not be employed for the operation of toys.
•Operation onboard an aircraft, a ship or a satellite is prohibited.
•omlox WTags and the real-time location system BeSpoon RTLS may
only be operated by qualified adult individuals. Installation and
operation in childcare facilities and other places hosting children is
prohibited.
•Any changes or modifications not expressly approved by BeSpoon
could void the user's authority to operate this equipment.
3omlox WTag User Guide
•Opening the casing of an omlox WTag and/or replacing any of its
component, including the battery, is prohibited.
•omlox WTags only operate (i.e. receive and transmit UWB signals)
within a complete UWB real-time location system BeSpoon
RTLS, which must be professionally installed.
•In case omlox WTags, including their batteries, must be disposed of,
they must be collected in compliance with Directive 2012/19/EU (Waste
of Electrical and Electronic Equipment).
2.2. Battery

•Charge omlox WTags with a charging station approved by BeSpoon.
•The omlox WTag was inspected carefully before shipment. However, in the
case any abnormality of bad smell or heat, etc, arises after purchase, please
contact BeSpoon.
•For long-term storage, please charge at 0.5C° for about one hour in
advance

CAUTION
•Do not put into a fire, or heat, do not store the in high temperature
environment.
•Do not drive a nail in, hit with a hammer, or stamp, do not strike in
other ways.
•Do not submerge in water, do not wet.
•Do not leave on a charging station or equipment if it generates any
deterioration (weakening and/or heat, color and/or shape changes,
electrolytes, or cause leaks, etc.) or any abnormality.
•Do not discharge continuously when it is not charged.

4. Deployment instructions
4.1. omlox WTag start
omlox WTag starts on motion.
To keep using your WTag, just ensure that the wave form led lights in green: it
means the battery level is high enough to operate.
▶ see table in section 3.1
4.2. omlox WTag placement
One simple golden rule ensures the best results when it comes to the
deployment: avoid UWB signal deterioration and reflection by maximizing Line
of Sight links (LoS) among all the devices included in the system. LoS matters
among omlox Satellites for the quality of synchronization. Of course, it also
matters between omlox Satellites and WTags for the location precision.

4.3. omlox WTag control
omlox WTags are configured and controlled via the Web UI of BeSpoon RTLS or
via another application based on a compatible session protocol.
For more information, please refer to the corresponding documentation. It can
be either the documentation included in the RTLS DELIVERY Pack or the docu-
mentation dedicated to the compatible application.
