WORKING ANYWHERE

摘要

Ross Yu, product marketing manager, Dust Networks Product Group, Linear Technology Corp, explains how SmartMesh embedded wireless mesh networks enable sensors to be placed 'anywhere'. Whether on the surface of a city street to sense available parking spots, or in industrial hazardous locations, the demand for sensor information has never been higher, and new applications require sensors to be placed in locations that were previously thought to be impractical. In order to place a sensor anywhere data needs to be collected and sensors must be truly wireless - both for communications and power. Since sensors need to be placed optimally for data collection, and not necessarily optimally for RF communications, the devices must be able to communicate both reliably and securely if wireless sensor networks are to continue to gain acceptance and to be used ubiquitously.
