Introduction
PAL-650 is a wireless tagging and identification system designed for the real-time inventory and
tracking of indoor assets. Applications include hospitals, warehouses, sea freight, supermarkets,
retail stores, robotic vehicles, manufacturing and security. Utilizing MSSI’s patented ultra
wideband (UWB) technology, the PAL-650 system has a real-time, 2-D or 3-D resolution
capability of one foot. Much higher resolutions can be achieved with software averaging
techniques. With the use of short pulse, UWB technology, the system is highly immune to
multipath effects which plague other wireless tagging solutions (e.g., spread spectrum) designed
for indoor operation.
PAL-650 is easily installed and requires no precision cables or calibration. A set of three or four
receivers, located at the corners of the region to be supervised, together with a network hub and
reference tag are all that are required for system infrastructure. The individual tags are
programmed with unique ID codes which are used for inventory and tracking. Because of the
unique properties of UWB technology, the tags have an extremely long battery life of better than
five years.
As with any RF technology, there are certain precautions that must be observed to prevent
interference to other systems. Please carefully read the following sections to properly install and
operate your PAL-650 system.
2.
Information to User
PAL-650 operation is authorized under FCC Part 15.517 as an indoor ultra wideband (UWB)
system. As such, there are certain precautions which must be taken during installation to assure
compliance with FCC regulations.
a. Changes or modifications not expressly approved by Multispectral Solutions, Inc.
(MSSI) could void the user’s authority to operate this equipment;
b. Each passive receiver (with a typically system having 4 or more) must be located
indoors, and with its directional antenna facing inwards; i.e., not intentionally directed
outside (e.g., out a window or external doorway);
c. The individual PAL-650 tags must not be used outside – see warning label on the bottom
of tag housings.
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.

Installation and Operating Instructions
The first step in installing the PAL-650 system is to locate and position the passive PAL-650
Receivers.
Note: The PAL-650 Receivers must only be operated indoors
and with their directional antennas facing inwards, in order to
ensure compliance with FCC Part 15.517.
For optimum performance, the PAL-650 Receiver locations should be chosen so as to provide
adequate coverage of the area of interest. Typical ceiling mountings for the Receivers are
illustrated in Figures 1 and 2 below.
Figure 1. Typical ceiling mount for PAL-650 Receiver. Note placement of directional
antenna (pointing inwards).
Figure 2. Another typical ceiling mount for PAL-650 Receiver.
The Receivers are interconnected (daisy-chained) via CAT-5 cabling, which is also used to
provide power to the units from the PAL-650 Hub and Power Distribution System (Figure 3).

Please see the User’s Manual for the PAL-650 Hub and Power Distribution System for
information on how to connect the Hub to a separate computer for 3-D display of tag positions;
and for instructions on how to calibrate the system.
Once the receivers and hub are installed and interconnected, the PAL-650 tags (cf. Figure 4
below) need to be activated. To do so, remove the metal ring (cf. Figure 5) which attaches the
polystyrene protective bottom plate to the tag radome using the special tool provided with the
system. Once disassembled, the tag internal battery will be visible. (The tag battery should last
at least 5 years in regular service.)

When delivered, the tags are provided with a protective tab (cf. Figure 6) which disconnects the
internal lithium battery from the rest of the tag circuitry. Once this tab is removed, the tag is
activated and can then be used for precision localization applications.

UWB Precision Asset Localization (PAL)
Multispectral Solutions, Inc.
(MSSI) was founded in 1988, by
President and CEO Dr. Robert J.
Fontana (Ph.D. Stanford).
MSSI is recognized worldwide as
the industry leader in Ultra
Wideband (UWB), an emerging
wireless technology for
communications, precision
localization and radar applications.
Throughout its nearly 15 year
history, MSSI has developed a
strong reputation for quality and
innovation. Our clientele includes a
wide variety of Government
agencies, military organizations and
commercial corporations.
The real-time inventory and tracking of assets is a problem that plagues
both military and civilian operations alike. MSSI has developed an Ultra
Wideband (UWB) precision asset tracking and location system that permits precise, 3-D localization of objects in a wide variety of operational
environments.
Originally developed for DARPA and the U.S. Navy, the system has
been successfully fielded onboard a Navy cargo ship to accurately track
and identify ISO containers within the ship’s hull. Achieving a positional accuracy of approximately one-foot, even in the presence of severe
multipath (i.e., RF reverberation), the system far outperformed conventional spread spectrum implementations.
MSSI has partnered with PARCO Merged Media (Portland, ME) to develop an asset tracking system for the health care industry. The UWB
geolocation system allows hospitals and emergency personnel to know
the exact status and location of patients, caregivers, and essential equipment to resolutions of one foot. By their unique design, MSSI’s UWB
devices are especially well suited to RF spectrum-sensitive areas of the
hospital. The system is also suitable to warehouse, sea freight, supermarket, retail store, robotic vehicle, manufacturing and security applications.
The UWB Precision Asset Geolocation (PAG) tag has a size of approximately 1.75” diameter and 1” height, and has an operational life of more
than 5 years using a small button cell battery.
