1. A wireless distress system for identifying the location of a mobile wireless distress transmitter in a multi-dimensional environment, the system comprising:
- a first wireless distress transmitter capable of transmitting a signal; and
a second wireless transmitter in a known location, capable of transmitting a signal unique to the location of the second wireless transmitter;
a processing device comparing the signal transmitted by the first wireless transmitter with the signal transmitted by the second wireless transmitter, and identifying the location of the first wireless transmitter as the known location of the second wireless transmitter if the signals substantially match.

Abstract
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.

8. A wireless distress system for identifying the location of a wireless mobile distress transmitter, the system comprising:
-
at least one mobile wireless distress transmitter operable to transmit a signal unique to the origin of the signal and the location of the mobile wireless distress transmitter; at least two spaced apart fixed wireless distress transmitters each located in a known location, and each being operable to transmit a signal unique to the origin of the signal and the location of each of the fixed wireless distress transmitters; a plurality of repeaters operable to receive and relay the signals transmitted from the wireless distress transmitters; and a processing device configured to receive the signals transmitted from the repeaters, associate each of the signals with a vector, compare the vectors associated with the signal transmitted by the mobile wireless distress transmitter with the vectors associated with the signals transmitted by the fixed wireless distress transmitters, and identify the location of the mobile wireless distress transmitter as the location of the fixed wireless distress transmitter transmitting a signal associated with a vector that most closely matches the vector associated with the signal transmitted by the mobile wireless distress transmitter. - View Dependent Claims (9, 10)
