Introduction
In 2004, a team of advanced signal processing and deep space communications scientists and engineers led
by Dr. Ramin Sadr formed Mojix
®
Inc with the vision of applying the technical breakthroughs in deep space
communications to the commercial wireless infrastructure industry. The result is a commercial passive RFID reader
system with capabilities orders of magnitude beyond previous RFID reader offerings, and a new generation of RFID
system technology that eliminates the economic and technical barriers to large-scale, high-volume RFID deployment
to deliver on the full promise of RFID.
The Mojix family of products can be configured to
transmit and receive across the UHF band and can
operate in both the near and far fields which make
it possible for a single system to read tags at the
pallet, carton or item level. The UHF or ISM band as
it is commonly referred to, is partially allocated for
public use and is heavily utilized by many different
devices and applications which make operating in
this spectrum especially challenging.
The STAR Receiver is powered directly by its power
supply and in turn powers each Mojix eNode
™
.
Each eNode is connected to the STAR by coaxial
cable and receives supply voltage, command and
control signals, and baseband RF over this medium.
The STAR Receiver is typically connected to the
enterprise via the LAN or an optional WLAN.
An eNode, as depicted in Figure 1, creates and is
associated with a single interrogation space, which
is individually addressed and controlled by the STAR
Receiver. eNodes are physically positioned according
to business process needs to provide optimal performance in exciting Gen2 RFID tags. The STAR Receiver is ordinarily
positioned with a vantage point to all eNodes in the system — this can be line of sight (LOS) or non-line of sight (NLOS)
but always within the rated Rx range.
