发明名称 Wireless Distress System
摘要 A wireless distress system and method compares signals transmitted from fixed wireless devices to more accurately determine the location of a mobile wireless distress device. The system and method may compare the signal pattern of a mobile wireless device to the signal patterns of fixed wireless devices in known locations. The location of a fixed wireless device with a signal pattern that most closely matches the signal pattern of the mobile wireless device may be used as the location of the mobile wireless distress device.
