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.

An active repeater device including a first antenna array, a controller, and one or more secondary sectors receives or transmits a first beam of input RF signals from or to, respectively, a first base station operated by a first service provider and a second beam of input RF signals from or to, respectively, a second base station operated by a second service provider.

An active repeater device includes a primary sector and one or more secondary sectors, receives a first beam of input RF signals. A first set of analog baseband signals, are generated based on received first beam of input RF signals. The first set of analog baseband signals are converted to a first set of coded data signals and control information is extracted from the first set of coded data signals by decoding only a header portion of the first set of coded data signals without demodulation of data portion of the first set of coded data signals. Based on the extracted control information, the first set of coded data signals are transmitted as beams of output RF signals to remote user equipment. The transmission is independent of demodulation of the data portion within the active repeater device to reduce latency for transmission of the first set of coded data signals.

In an embodiment, a signal repeater includes a master unit and a remote unit that are optically coupled to one another by, e.g., an optical fiber. The master unit includes master-unit circuitry configured to receive an input electrical signal from a satellite-signal receive antenna, and to convert the input electrical signal into an optical signal. And the remote unit includes remote-unit circuitry configured to convert the optical signal into an intermediate electrical signal, to amplify the intermediate electrical signal to generate an output electrical signal, and to couple the output electrical signal to a retransmission antenna. Because an optical channel, such as an optical fiber, typically attenuates an optical signal significantly less per unit of distance than a coaxial cable attenuates an electrical signal, such a signal repeater allows a satellite receive antenna to be located at a significant distance from a retransmit antenna.
