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.
