摘要： A method includes displaying a reference polar coordinate system on a display screen, and displaying a radiation pattern image on the display screen in juxtaposition with the displayed reference polar coordinate system. In another aspect, an angled line is drawn on a display screen to represent the proposed layout of a leaky coaxial cable. A point of interest is selected that is spaced from the proposed cable layout, and one of the segments of the cable is determined as likely to produce a dominant level of irradiation with respect to the point of interest.

摘要： A method for generating radio frequency (RF) planning modeling data for an object. The method includes placing an RF signal source near the object and sequentially positioning a receiver at a plurality of locations around the object. At each of the locations, an indication is provided to the receiver that it is at a measurement location, and the receiver is allowed to detect a level of the RF signal produced by the RF signal source at the measurement location. In another aspect, an opening in an object is modeled as a virtual object that overlaps with the object and has a “negative attenuation” characteristic to cancel out the “positive attenuation” characteristic of the object.

摘要： A method includes providing a first set of location data using a first coordinate system that corresponds to a first building and a second set of location data using a second coordinate system that corresponds to a second building. A third set of location data is generated from the first and second sets of location data by converting the first set of location data from the first coordinate system to a third coordinate system and converting the second set of location data from the second coordinate system to the third coordinate system.
