Regulatory Information/disclaimers
Installation and use of this Wireless Radio device must be in strict accordance with the
instructions included in the user documentation provided with the product. Any changes or
modifications made to this device that are not expressly approved by the manufacturer may
void the user’s authority to operate the equipment. The Manufacturer is not responsible for
any radio or television interference caused by unauthorized modification of this device, of the
substitution or attachment. Manufacturer and its authorized resellers or distributors will
assume no liability for any damage or violation of government regulations arising from failing
to comply with these guidelines.
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.
Instructions concerning human exposure to radio frequency electromagnetic fields:
To comply with FCC Section 1.307 (b) (1) for human exposure to radio frequency
electromagnetic fields, implement the following instruction:
A distance of at least 20cm. between the equipment and all persons should be maintained
during the operation of the equipment. The minimum distance will be determined after testing
has been completed.

The FCC Wants You to Know
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:
a) Reorient or relocate the receiving antenna.
b) Increase the separation between the equipment and receiver.
c) Connect the equipment to an outlet on a circuit different from that to
which the receiver is connected.
d) Consult the dealer or an experienced radio/TV technician.
FCC Warning
Modifications not expressly approved by the manufacturer could
void the user authority to operate the equipment under FCC
Rules.

Abstract
This document describes the iLocate system hardware:
1. PBC beacon, Precyse part # BC91/403000, referred to as the PBC.
Product description
PBC beacon:
The PBC is used to define a location zone. It is based on a microcontroller and 4 RF
transceivers.
It uses the iLocate proprietary protocol which provides a 2 way, half duplex communication with
the base station and to transmit its ID to the SATs.
The unit is DC powered, 12 – 24Vdc, up to 100mA.

System test configuration
Beacon
The unit was configured for normal operation. In this mode the beacon transmits its ID
packet continuously, with 20% duty cycle.
For intermodulation tests, the unit was configured to transmit on all 4 channels
simultaneously.
The unit transmission channels were set to 0 (905.0MHz), 8 (911.4MHz) and 16 (917.8MHz).

Method of operation
The PBC has 4 independent transceivers. The transceivers cannot operate as MIMO or
phase array (beam shaping).
All the transceivers are connected to a single low power microprocessor unit. Each
transceiver in the unit transmits its identification packet at 20% or lower duty cycle.
Each transceiver operates at a different 800KHz band (905.0, 905.8, 906.6 etc).
One of the channels (One which has the best reception from the base station) acts as a
communication channel to the base station.
This unit’s function is to provide location information to the mobile agents (tags). Upon
packet reception, the tag transmits its signal strength (RSSI) and ID to the base station, and
its location can be calculated using various algorithms.

Unit definitions:
Base station, referred to as PBS: A radio device that transmits data to and from the tag (SAT) to a
personal computer (PC), also provides synchronization signal. The unit is powered by a DC power
supply.
Beacon, referred to as PBC: A radio device that defines a location. Location detection can be
realized through one or more PBCs. The unit is powered by a DC power supply.
Tag (SAT): A radio device that is used to track and monitor assets. It communicates with the PBS
and can detect the PBC signals.
Marketing and installation
1. EUT intended use and application: The BC91403000 (PBC) is used as a radio
beacon for the iLocate system. By transmitting a constant signal, it allows the tags
(SA24003000) to identify their location. The EUT is installed either indoors or
outdoors (inside an appropriate sealed box). The installation requirements are proper
site planning, infrastructure (AC supply with an AC to DC adapter or DC supply,
mechanical mounting, clearance around it), sealed box (Per Precyse tech
requirements, an IP55 or equivalent box uninterrupted power supply where required,
etc).
2. Marketing: The EUT is sold to system integrators only. It is not available for non
qualified persons or integrators.
