RAE Systems, Inc.'s RDK Ruggedized Host, a host controller for AreaRAE toxic gas and radiation sensor networks, consists of a rugged laptop computer with an embedded RAELink wireless modem and pre-configured ProRAE Remote software. The controller provides real-time communication with up to 64 remote monitors, and logs sensor data for historical viewing and interfacing with third-party software. The embedded RAELink modem provides the network with a two-mile range, giving incident commanders the ability to manage the sensor system from the “safe zone.” When connected to the Internet the controller can push data over a secure web browser for real time use by remote specialists. It can also send alarm conditions to cell phones via text messages. Applications for the ruggedized host include hazardous materials response, public venue protection and short-term industrial deployments as well as mobile network applications.
