摘要： In a radio communications network (20) having a plurality of cells (34) employing a plurality of cell site configurations (22, 24, 26, 28, 30, and 32), a computing system (116) and a computer-based method (178) create a hierarchical data structure (136) modeling the radio communications network (20). The hierarchical data structure (136) is created using object oriented programming methodology to create objects, representing the various physical components of a cell site. In addition, objects are created to represent the auxiliary information, such as available channels, channel assignment constraints, carrier-to-interference ratios, and neighbors lists under which a particular radio communications network configuration is devised.

摘要： A method, executed on a simulation system (20), characterizes propagation of a radiofrequency signal (56) in a three-dimensional environment (52). The method includes forming a database (42) of propagation paths (54) of the radiofrequency signal (56) transmitted from a transmitter (58) at a fixed location (66) in the three-dimensional environment (52). The propagation paths (54) are represented by a plurality of line segments (120, 122) in the database (42). Local line segments (188) are selected from the plurality of line segments (120, 122) to establish a subset (47) of the propagation paths (54). The subset (47) includes those propagation paths (54) each having one of the local line segments (188) proximate a location (182) of a receiver (72) in the environment (52). Distinct multipath components (246) representing distinct wavefronts of the radiofrequency signal (56) are subsequently identified from the subset (47) of the propagation paths (54).

摘要： A system and method for wireless network planning utilizing raster data, stored and manipulated in raster data planes (204-212) and vector data (522) stored and manipulated in vector data planes (528-532). The invention increases the accuracy of network planning by simultaneously utilizing vector data planes (528-532) and raster data planes (204-212) to perform computations using vector features contained within map pixels (604). The disclosed method makes it possible to perform accurate computations such as propagation loss to vector points (602) contained within map pixels (604). Accuracy is further increased because other characteristics such as received power, elevation, and best server can be computed to the vector features rather than processing them with traditional raster resolutions.

摘要： Today, power distribution systems can be used to supply power to many loads, and since many loads, such as servers, are reactive (i.e., have capacitors and/or inductors), line distortion and power factor can be an issue. Conventional techniques to correct for line distortion and power factor use a specialized circuit that is generally in series with the load, but these specialized circuits can be prohibitively expensive when used in large numbers. Here, however, a corrective power supply has been provided, which can correct for other parallel power supplies that can reduce cost.
摘要翻译：今天，配电系统可以用于向许多负载供电，并且由于诸如服务器的许多负载是无功的（即，具有电容器和/或电感器），所以线路失真和功率因数可能是一个问题。用于校正线路失真和功率因数的常规技术使用通常与负载串联的专用电路，但是当大量使用时，这些专用电路可能是非常昂贵的。然而，这里提供了一种校正电源，可以校正可以降低成本的其他并联电源。
