Cubic GTS designed the Next Generation Wireless Communication for Logistics Applications (NGWC) mesh network to meet the U.S. Army NGWC requirements. The Overview section explains the CGTS mesh network operation. 3.1 Remote Sensor Unit The Remote Sensor Unit (RSU) provides identification, security and sensor monitoring. The remote sensor can measure temperature, humidity, motion, light, battery charge, shock, and door state. A RSU also provides connectivity for other RSUs through the mesh network. For more information about the RSU, see the Remote Sensor Unit section. 3.2 CGTS mesh network Overview CGTS mesh network connects RSUs that act as remote sensing units to a web based Device Management Center (DMC). The DMC collects information from the RSUs and stores the data on the server. You can use the web access to the DMC to manage the mesh network. Data is communicated securely between the RSUs and the DMC in encrypted packets, and the DMC provides secure management of the collected data. A gateway between the RSUs and the DMC provides communication between the RF network of RSUs and the Internet. The RSUs communicate using the CGTS proprietary protocol stack based on IEEE 802.15.4 physical layer at 2.4 GHz using all 16 channels. 3.3 The Device Management Center The Device Management Center (DMC) is located at a Cubic GTS facility. The DMC provides the following services: Secure storage on the DMC for data that is transmitted securely from CGTS mesh network devices. Secure system management of the CGTS mesh network. Worldwide health monitoring of the RSUs in the CGTS mesh network. Event notification to individuals via email or short messaging service (SMS). Software upgrade of deployed devices (future functionality). 3.4 CGTS mesh network Operation The mesh network that is formed by the Remote Sensor Units (RSUs) and the gateways operates independently of the Internet connection that forms the link between the gateways and the Device Management Center (DMC). This section describes the foundation of the mesh network operation between the gateways and the RSUs. The CGTS mesh network allows for multiple paths between the RSUs and the gateways in the network. Because the data path through the network is non-deterministic, the CGTS mesh network is an ad hoc network.

Announcing, or beaconing, the presence of this RSU. Performing scheduled communication with other RSUs or sinks.
Copyright © 2009-2010 by Cubic GTS RSU-3 User Guide 7 Cubic GTS Proprietary and Company Confidential Information 4 Remote Sensor Unit A Remote Sensor Unit (RSU) communicates with the DMC through RF signals to an FMG or MMG. A RSU that includes GPS capability is called a RSU-GPS. 4.1 RSU A RSU is shown in Figure 1. A RSU is packaged in a rugged IP66 production housing. It has several mounting options which include built-in self tapping screws, glue-on mounting sled, strap holes, optional magnet mounts. RSU can include up to four A size lithium batteries, and has an integrated antenna. A RSU sensor measures temperature, humidity, motion, and light, and monitors the state of magnetic door sensor. The battery life varies based upon the RSU configuration, but the minimum battery life can be guaranteed for any specific configuration. Figure 1: Remote Sensor Unit (RSU) 4.2 RSU LEDs The RSU LEDs function as follows by default: Short blink (~20ms) red every 2.5 seconds if not connected to a network. Short blink green every 2.5 seconds when connected to a network. Long red blink on magnet transition (1s). To control light pollution LED blinking can be slowed down and turned off. 4.3 RSU Sampling and Reporting Behavior A RSU has the following sensor sampling behavior by default: Door sensor and shock sensor cause immediate sampling. Other sensor sampling is every 20 minutes. A RSU has the following reporting behavior by default: Sends a sensor report every 2 hours. Sends a report on a magnet touches immediately or if default sensor thresholds were surpassed during sampling. Sends a GPS every 24 hours (RSU-GPS only).
