Abstract
The knowledge of the spatial coordinates of an object is an inestimable information required for many applications in many fields. This information is highly needed in the telecommunication field and particularly, in the emerging context of connected objects. In this area, the environment awareness enhanced by the location based adaptability is the key of success to ensure energy efficient pervasive communication. High data rate wireless communication may also benefit from the location information by using modulation in the spatial domain, in addition to modulation in frequency, time or code domain. To access the spatial domain, a microwave interferometric location system (MILS), leading to a two dimensional (2D) location, has been developed. The combination of this phase sensitive device with a stereoscopic measurement allows a precise 3 dimensional (3D) indoor location. Tested, indoor and outdoor, at a frequency compatible with Bluetooth applications, this system point out the feasibility of such approach.
