RAE Systems Selects Ember to Deliver Mesh Networks for Wireless Sensing Solutions in Ocean Shipping Containers

SUNNYVALE, Calif. and BOSTON, Mass- October 21, 2003 -RAE Systems Inc. (AMEX: RAE), a leading provider of hazardous environment detection solutions for homeland defense, today announced the selection of Ember Corporation, a leader in wireless networking solutions, to provide an embedded mesh networking topology to extend RAE Systems’ ad hoc deployable sensing networks for intermodal ocean shipping containers. The companies will demonstrate a prototype of this multi-parametric sensing solution at the U.S. Maritime Security Expo in New York, October 29-30, 2003.

“RAE Systems monitors the integrity of ocean shipping containers by adding a mix of radiation sensors, toxic chemical sensors and intrusion detectors,” said Robert Chen, CEO of RAE Systems. “With the addition of Ember’s mesh networking we are able to integrate the signals from multiple sensors to increase the detection capability of a potential breach of the container.”

RAE Systems’ hazardous environment sensors and rapidly deployable ad hoc networks are used by first responders, armed forces, government agencies and private industry in all 50 states and in more than 40 countries around the world. Ember’s embedded radio chips, EmberNet(tm) networking software, and network management tools use a flexible mesh routing algorithm, creating extremely resilient, self-organizing and self-healing networks, with very low power requirements and no single point of failure. Ember-enabled devices automatically route traffic around the typical interference found in difficult radio conditions, resulting in increased flexibility in deployment, maintenance and operation.

“The combination of Ember’s intelligent wireless capabilities with RAE Systems sensors creates a powerful, robust solution for critical homeland defense sensing networks, whether in container shipping, battlefield situations, fenceline monitoring, or public venue protection,” said Jeff Grammer, CEO of Ember. “In these harsh RF settings, networks and sensors provide critical information. Ember’s low power, resilient design provides a fault-tolerant topology that ensures that sensor data flows as intended, even in volatile, difficult environments.”
