Abstract
A search and rescue (from hereon, SAR) optimization/prevention system is set forth, for ensuring the safety and connectivity of people in locations such as but not limited to national parks, hiking trails, mountains, lakes, rivers, forests, and other areas that do not receive (or receive inconsistently) reliable cellular, satellite, or GPS network connectivity. The mesh network system comprises wearable devices used by the person being located, and transceivers responsible for getting a signal from the user to a responder via the bouncing of a signal. Once a signal is received at a designated transceiver, the system may output information about the at least approximate location and condition of the user that transmitted the signal, including the approximate location, time of distress, and other pertinent data, based on information carried in the signal.
