    摘要: A method and system for generating three-dimensional antenna patterns from two-dimensional cross sections. The method involves an estimate (1006), on a given vertical plane, obtained by rotating a gain value (1010) from the front of the vertical pattern using the horizontal pattern (1004) as a weight; a second estimate, which could be on a separate vertical plane, obtained by rotating a gain value (1014) from the back of the vertical pattern, and a final estimate (1206) obtained by connecting the first two estimates across their respective planes. The invention yields smooth reasonable surfaces (1704) that satisfy the vertical and horizontal boundary conditions, exhibits no mathematical artifacts, and improves the accuracy of propagation calculations of radio frequency signals. The method is implemented in a software system (1812) that provides interactive analysis and visualization capabilities for antenna patterns in three dimensions.

    摘要: A computing system (36) provides a network designer with a mechanism for modeling migration, or a shift, of call traffic from a first server (26) operating using a first technology type to a second server (28) operating using a second technology type. The system (36) executes a traffic map generation process (56) for generating a first traffic map (60) responsive to a radio coverage area (30) and a call traffic load (84) for the first server (26), and for generating a second traffic map (62) responsive to a radio coverage area (32) and call traffic load (90) for the second server (28). The system (36) executes a call traffic migration modeling process (58) to adapt the second traffic map (62) to include a proportion (100) of the first call traffic load (84) to be shifted from the first server (26) to the second server (28).

    摘要: A system (200) provides a network designer with a mechanism by which to quickly estimate the performance of a code division multiple access wireless communication network. The system (200) allows the designer to enter a group of network and sector parameters.

    摘要: A system (200) provides a network designer with a mechanism by which to quickly optimize the load distribution in a wireless communication network (100) by iteratively modifying the pilot power settings within an analysis session. The system (200) determines a reverse interference level for the network (100). The system (200) then adjusts the pilot power level of each sector by an amount equal to the difference between a sector's reverse interference level and the network's reverse interference level. The system (200) assigns, based on the adjusted pilot power levels, each wireless device (140) in the network (100) to a sector.

    摘要: Estimating a vehicle's driving range by combined processing of measured and calculated range data. A measured range it is adjusted to account for processes not included in the original measurements. These adjustments may include changes in road surface, terrain elevation, aerodynamic drag, or other losses. The resulting model is thus relative to the conditions used in quantifying vehicle range by calculating contributions that either penalize or enhance the measured range. This method is implemented in a software system that can also provide real-time display of the range for both a single trip or a contour that illustrates what the range is for all directions.
