Claim:
1. A method for utilizing cellular signal strengths as a function of location for path navigation and guiding a user of a mobile device to reach a destination with sufficient cellular signal strength for establishing communication, comprising: a) Measuring, by the mobile device, one or more cellular signal strengths at selected predetermined distance or predetermined time interval throughout a path traveled by the user; wherein each of the measured one or more cellular signal strengths is determined with a strength level of strong, low or undetectable; b) Determining, by a Global Positioning System (GPS) of the mobile device, sequential location points at said selected predetermined distance or predetermined time interval throughout said path traveled; wherein the GPS utilize communication signals other than cellular signals; c) Associating, by the mobile device, said GPS determined sequential location points with the measured one or more cellular signal strengths; d) Storing, by the mobile device, the measured one or more cellular signal strengths and said GPS determined sequential location points to the mobile device's internal memory; e) Retrieving said stored one or more cellular signal strengths and said stored GPS determined sequential location points from said internal memory; f) Displaying, by the mobile device, a map with said GPS determined sequential location points as icons representing the strength level of each of the stored one or more cellular signal strength; wherein different icons are utilized for representing the strength level of strong, low or undetectable; g) Tracking in real time, by the GPS of the mobile device, the mobile device's current location; and h) Display in real time, by the mobile device, the tracked current location on the map in respective to the displayed icons; thereby enabling the user to navigate along the displayed icons.
