1. Wireless STAR System Components
The Mojix Wireless STAR system is a single network element at the enterprise edge.
Based on Mojix's innovative distributed architecture, a single system consists of one or
more STAR units managing up to 512 low-cost Mojix eNode transmitters. Mojix eNodes
provide energy to all passive RFID tags within their specified interrogation spaces, while
the centralized, high-sensitivity Mojix STAR reads the resulting tag signals from across
the system's potentially vast coverage area of up to 250,000 sq. feet.
A Wireless STAR communicates configures and manages wireless eNodes through a
command link. A command link antenna replaces the cabled interface between STAR
and eNodes.
1.1. Mojix Wireless eNodes: Distributed Transmitters
Each Wireless eNode excites all passive RFID tags within its designated interrogation
space and can be deployed as needed to shape discrete, overlapping or contiguous
interrogation spaces, including configurations to create virtual fences for securing
tagged items.
Mojix Wireless eNodes are designed to excite all EPC UHF Gen2 RFID tags within their
designated interrogation spaces with an excite range of over 30 feet and a coverage
area of more than 2,500 square feet, depending on tag sensitivity. While the wireless
STAR can manage up to 512 wireless eNodes, it also shares in the management of a
deployable sensor network in support of numerous concurrent business processes.
1.2. STAR Interrogation Spaces
Fixed or mobile interrogation spaces are business process specific and can be
optimized for tag density or coverage. Each individually controlled interrogation space is
created by the deployment of single or multiple wireless eNodes and is dynamically
sized by the wireless STAR system, through individual exciter power output control.
1.3. Master Controller
The STAR-1000 signal processing platform is linked to an edge appliance called a Master
Controller (MCON), and communicates via a standard Ethernet 10BaseT (RJ45)interface.
The MCON can drive an arbitrary number of STAR-1000 systems and includes interfaces to
the enterprise middleware. In a larger enterprise deployment, multiple STAR domains would
exist in various locations and would require one or more controllers a clustered
configuration.

2. Installation Guide Lines
The detailed hardware specifications, including mechanical requirements, are identical
to the cabled version of the STAR system and are detailed in the STAR-1000 user
manual, as well as the configuration and operational guidelines.
What follows is an addendum to the user manual detailing the specifics applied to the
installation and interfaces of the Wireless STAR and eNode.
2.1. Wireless STAR Command link antenna
Wireless STAR uses the command link antenna to communicate with wireless eNodes.

Appendix F: FCC Notice
INSTRUCTION TO THE USER
The user is cautioned that changes or modifications not expressly approved by the party
responsible for compliance could void the user’s authority to operate this equipment.
INSTRUCTION TO THE USER
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.
This equipment has been certified to comply with the limits for a class B computing
device, pursuant to FCC Rules. In order to maintain compliance with FCC regulations,
shielded cables must be used with this equipment. Operation with non-approved
equipment or unshielded cables is likely to result in interference to radio and TV
reception. The user is cautioned that changes and modifications made to the equipment
without the approval of manufacturer could void the user's authority to operate this
equipment.
CAUTION: To comply with FCC RF exposure compliance requirements, a separation
distance of 20 cm must be maintained between the antenna of this device and all persons.
