Localization for low cost sensor network

摘要: Wireless devices, systems and approaches or methods having the capability of determining location a given wireless device. An example system includes device that generates at least one pulse as part an output signal, is captured by anchor devices used, in time arrival approach, to determine The may be generated during designated portion otherwise normally modulated message. Another node directional direction signal including data indicating its direction, directions signals from plural nodes when pointed are used Combinations antenna systems, within each these associated with also included.
