Mojix Announces Availability of Its Next-Generation RFID System

The Mojix STAR 3000 offers cloud-based applications, industry-specific solutions, smartphone compatibly and improved performance, the company reports.

Jun 05, 2012Mojix Inc. has announced the general availability of the next generation of its Space Time Array Reader (STAR) radio frequency identification technology, which reads passive EPC Gen 2 RFID tags over a longer distance than traditional EPC Gen 2 interrogators. The latest version, known as Mojix STAR 3000, offers two key new features: a cloud-based hosted server, enabling users to deploy a system at a lower cost by eliminating the need to acquire software, and functionality specific to each of the five vertical markets (retail, automotive, industrial manufacturing, logistics and warehousing, and oil and gas), including hardware form factors specific to each sector. Ramin Sadr, the company's CEO and founder, says that compared with previous versions of the STAR system, Mojix 3000 offers a longer read range and greater read reliability—based, in part, on new antenna modifications and improved location-tracking functionality provided by new signal-processing algorithms for location estimation.

Mojix has also begun providing mobile client software for smartphones, so that its customers could utilize the handsets as Near Field Communication (NFC) readers or bar-code scanners to, for example, capture data at such remote locations as a farm or delivery point, and to then forward that information to a server.

In 2008, the company launched the first version of its STAR system (see Mojix Takes Passive UHF RFID to a New Level), which won that year's RFID Journal Award for Best in Show (see The Brightest Star). With the STAR 3000 system, Mojix says, its aim is to offer a solution that could be easy and inexpensive to deploy within numerous markets, and that could be installed enterprise-wide, with a shared network—in other words, tags could be tracked from farm to fork within supply chain environments, or from manufacturer to store shelf. Like its predecessors, the new Mojix 3000 system consists of the Mojix eNode, which acts as an exciter and includes four to 16 antennas that emit a signal to power passive EPC tags entering a coverage area. In response to an eNode's signal, a tag transmits a signal that is then picked up by a Mojix STAR 3000 receiver—which, in turn, forwards that data to a master controller (a server blade running the Linux operating system). The master controller processes the information for use by a warehouse-management system or other back-office software, or on the cloud-based server. The cloud-based software can also issue alerts when necessary.

A single Mojix STAR 3000 receiver can read tags at a distance of up to 1,000 feet within an unobstructed environment. Multiple STAR 3000 systems—each consisting of a single receiver and as many as 512 eNodes—can be networked together, for a combined total of up to 65,536 eNodes, to provide a 1-million-square-foot area with location accuracy of approximately three feet, the company reports.
