  • System and method for determining radio frequency coverage trouble spots in a wireless communication system
    Patent number: 6459695
    Abstract: A method that rapidly and precisely determines the geographical location of areas of high concentration of usage (hot spots) and areas of poor RF frequency reception (dead spots) by measuring the number of failed call attempts, dropped calls and the like and comparing them to the identification of a mobile station and its location are recorded as record at selected points during a call. If a high number of uncompleted calls or dropped calls are recorded, then the base station can use the last known location of the wireless units involved to circumscribe an area in which the hot spot or dead spot occurs.
