Figure 1 on this slide illustrates low-power wireless networks (LPWNs) that are used to automatically collect indications from metering devices (water, gas, electricity, etc.) without the need for human participation. Figure 2 demonstrates a highly effective and efficient method of asset tracking. Wireless sensor networks (WSNs) provide sensor and location information about valuable assets. Examples of WSN applications include container/vehicle tracking and monitoring, personnel identification, etc.
