A device designed to amplify cellular signals on boats and other watercraft allows for improved communication capabilities in areas where signal strength is weak or inconsistent. These systems typically consist of an external antenna to capture signals, an amplifier to boost the signal strength, and an internal antenna to rebroadcast the amplified signal within the vessel. For example, a recreational boater traveling offshore might use such a system to maintain contact with shore or access weather updates.
The capacity to enhance cellular connectivity on the water offers significant advantages. Improved communication facilitates safety by enabling distress calls and access to emergency services. It also supports operational efficiency for commercial vessels by enabling constant data transfer and communication between ship and shore. Initially, basic marine radios were the primary communication method; however, the advent of cellular technology and subsequent signal amplification technology has expanded the possibilities for marine communications considerably.
