A need exists to gather data form diverse sources for the purposes of system analysis and control. Many of these data sources are located in environments where power is unavailable, and space is at a premium. These environmental constraints coupled with market pressures that dictate rapid, costs effective installation establish the need for wireless data collection. Wireless systems redefine the term 'remote sensing.' This type of sensory information is thought of as non-intrusive and can be acquired at a location that is remote from the data source. This collection of data at a point remote from the source can be advantageous due to environment, access, or sociopolitical conditions. Remote sensing has many advantages from both a technical and commercial perspective. Highway bridge analysis using conventional methods can require several weeks of sensor and wire placement. As much as 6 miles of wire may be used to connect the sensors to get analytical results on one structure. High performance aircraft testing using hardwired sensors may require as much as 9 months of tedious wiring before tests can begin. At the conclusion of the tests, the wire must be removed so the aircraft can be returned to service. Using wireless remote sensing, these tasks can be performed in fractions of the previous time due to the dramatic reduction in wiring. Further, wireless technology can enable sensors to be placed at locations previously inaccessible due to space limitations.
