Ad-hoc RFID networks solve range problem

Australian company Syscan International has developed a system that enables RFID tags to communicate with other tags, creating ad-hoc networks.

The system called iCE (intelligent Communication Enbled) allows reliable data acquisition based on IEEE 802.15.4.

The technology designed to address the typical RFID constraints such as read reliability, read range and energy consumption.

iCE enables tags to communicate to other tags, creating ad-hoc networks.

Syscan’s iCE invention is claimed to ensure reliable data reads, increased read range, communication bridges, dynamic bi-directional network communications, and low cost, since only one reader is needed.

Typical RFID can have unreliable data reads, limited read range and struggle with metal, liquids and humidity. It also takes higher power consumption, does not provide dynamic communication and is ideally suited for static systems only. Users also require multiple readers and antennae at every tag read point.

iCE can provide mobile Resource Management (MRM), Container Management, Supply Chain Visibility and asset tracking.

The system uses a master–slave relationship, where the master is used to read the slave tags that are assigned to it. This inter-relationship is used to improve performance, battery life and range. Using this system, iCE can achieve up to a 350-metre read range. The slave tags report to the master that in turn reports to the iCE UMCD (universal monitoring and communication device) or iCE reader.

iCE UMCD-G

Using a GPRS Cellular network, the iCE UMCD-G sends the information it has gathered, including tag identification, GPS location and sensor data to the Syscan server where it provides real-time non-conformance information at the point of activity (i.e. temperature violations, door alarms). In non-moving applications, existing Wi-Fi network connections can be used to transfer the data.

Users have direct access to the data via the Syscan server and can view the information via Internet connection or integrate the information in their own software. As well email, text messages and phone alerts to problems are always accessible.

iCE UMCD-E

Using a company network or internet connection the iCE UMCD-E sends the information it has gathered to the Syscan server where it provides real time non-conformance information at the point of activity (i.e. temperature violations, door alarms, etc.).

Users have direct access to the data via the Syscan server and can view the information via an internet connection or integrate the information into their own software. Email, text messages and phone alerts can be added as an option.

iCE Reader Serial

Linked to a computer, the iCE Reader Serial can be used to read iCE tags directly.
