Abstract
Abstract A method and apparatus for providing network planning information in an interactive manner is described. A user selects a planning tool and inputs a selection point. If a line of sight cursor tool has been selected, a set of points on a display are set indicating a line of sight exists from those points to the selected point. If a path loss cursor tool has been selected a set of points on a display are set indicating a path loss to the selection point less than a certain threshold. Alternatively, a set of point on the display are set to various colors or shades indicating a range of path loss amounts to the selected point. In the preferred embodiment the invention incorporates the use of a computer system.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
162 words
A method for allowing evaluation of a placement location of a base station for a wireless telephone system comprising: (a) storing a set of elevations associated with a region over which the wireless telephone system will be implemented; (b) displaying said region on a display system; (c) receiving said placement location; (d) calculating a set of line of sight locations within a portion of said region from which said placement location can be seen wherein said portion of said region is substantially smaller than said region by (d.1) calculating a first slope from the placement location to a first location proximate to said placement location; (d.2) calculating a second slope from the first location to a second location located radially outward from said placement location; and (d.3) placing said second location in said set of line of sight locations if said second slope is less than said first slope; and (e) displaying said set of line of sight locations and said region.
Claim 2
Independent Claim
162 words
A method for allowing evaluation of a placement location of a base station for a wireless telephone system comprising: (a) storing a set of elevations associated with a region over which the wireless telephone system will be implemented; (b) displaying said region on a display system; (c) receiving said placement location; (d) calculating a set of line of sight locations within a portion of said region from which said placement location can be seen wherein said portion of said region is substantially smaller than said region by (d.1) calculating a first slope from the placement location to a first location proximate to said placement location; (d.2) calculating a second slope from the first location to a second location located radially outward from said placement location; and (d.3) placing said second location in said set of line of sight locations if said second slope is less than said first slope; and (e) displaying said set of line of sight locations and said region.
Claim 3
Dependent Claim
35 words
The method as set forth in claim 1 wherein step (c) is comprised of the steps of: (c.1) receiving positioning signals via a positioning device; and (c.2) receiving a selection signal via said positioning device.
Claim 4
Dependent Claim
15 words
The method as set forth in claim 2 wherein said positioning device is a mouse.
Claim 5
Dependent Claim
21 words
The method as set forth in claim 1 further comprising the step of: converting an x-y coordinate to a polar coordinate.
Claim 6
Independent Claim
226 words
A method for indicating the suitability of a placement location for transmitting and receiving radio frequency signals comprising the steps of: (a) generating data indicative of the ability of a radio frequency signal to be transmitted between said placement location and a set of surrounding locations within a geographical region, wherein said set of surrounding locations are much smaller than said geographical region by (a.1) determining if each location in said set of surrounding locations has a direct line of sight view to said placement location by (a.1.1) determining a set of points along a line from said placement location to and end point; (a.1.2) determining whether each point in said set of points has a line of sight view to said placement location by calculating a first slope of a first line from said placement location to a first point in said set of points that is closest to said location; calculating a second slope of a second line from said placement location a second point in said set of points that is closest to said first location; and setting said second point to visible if said second slope is greater than said first slope, and to not visible if said second slope is less than first slope; and (b) displaying said data within said geographical region on a display screen of a computer system.
Claim 7
Independent Claim
226 words
A method for indicating the suitability of a placement location for transmitting and receiving radio frequency signals comprising the steps of: (a) generating data indicative of the ability of a radio frequency signal to be transmitted between said placement location and a set of surrounding locations within a geographical region, wherein said set of surrounding locations are much smaller than said geographical region by (a.1) determining if each location in said set of surrounding locations has a direct line of sight view to said placement location by (a.1.1) determining a set of points along a line from said placement location to and end point; (a.1.2) determining whether each point in said set of points has a line of sight view to said placement location by calculating a first slope of a first line from said placement location to a first point in said set of points that is closest to said location; calculating a second slope of a second line from said placement location a second point in said set of points that is closest to said first location; and setting said second point to visible if said second slope is greater than said first slope, and to not visible if said second slope is less than first slope; and (b) displaying said data within said geographical region on a display screen of a computer system.
Claim 8
Dependent Claim
36 words
The method as set forth in claim 5 wherein step (a) is comprised of the step of: (a.1) determining a path loss amount with respect to said location for each location in said set of locations.
Claim 9
Dependent Claim
145 words
The method as set forth in claim 6 wherein step (a.1) is comprised of the steps of: calculating a set of points along a line from said placement location to an end point; determining whether each point in said set of points has a direct line of sight to said placement location; recording a first edge and a second edge for each of said set of points that does not have a direct line of sight view of said placement location; calculating said path loss amount using a direct line of sight path loss formula for each point in said set of points having a direct line of sight view to said placement location; and calculating said path loss amount using a knife edge formula for each point in said set of points not having a direct line of sight view to said placement location.
