In this day and age, communication is vital for human survival. In places where modern cell towers fail to reach, it is important to seek ways to mitigate potential ill fortunes. This, of course, requires something that provides more than just routine communication with the outside world. Enter personal locator beacons (PLB). Personal Locator Beacons are a type of emergency beacon. Once activated, they transmit signals that get picked up by the orbiting satellites. It then makes sure an alert is sent off to the emergency services unit. PLBs generally need an uninterrupted via of the sky for successful transmission.
