摘要： A subscriber device (10) includes one or more sensors (102) for measuring an object electromagnetic characteristic, such as conductivity, permittivity or permeability. A controller (104) stores the object electromagnetic parameter in memory (106) and, operating in accordance with a performance enhancement routine stored in the memory (106), enhances operation of the subscriber device (10) in accordance with the electromagnetic parameter. The controller (104) may do this by adjusting the power of an amplifier (112), the frequency of a synthesizer (114) or the impedance of an antenna (110). A software program controlling the subscriber device and a corresponding method are described.

摘要： A method (10 or 500) and system (200) for simulating and improving accuracy of empirical propagation models for radio frequency coverage can include a display (210) and a processor (202) coupled to the display. The processor can be operable to input (502 and 504) low-resolution data and high-resolution data, select (506) an area of interest being simulated for empirical propagation models, and classify (508) receivers as belonging to a predetermined type of object. If a receiver in the area of interest is a low resolution object, then normal losses can be applied (510). If a receiver in the area of interest is a high resolution object, then losses specific to the high resolution object can be applied (512). If a receiver is classified as being inside a building, then the processor can further compute (516) a median power for a location of the receiver and add in-building penetration losses.
