Underwater networks that are extended through a wireless network domain can enhance an underwater network's characteristics in terms of bandwidth, robustness, interoperability and distance. Central to the setup is a gateway buoy facilitating connectivity between the underwater network and the surface wireless network. Two distinct sets of measurements were conducted: one utilizing High Frequency (HF) and the other employing Long-Term Evolution (LTE) technology. The primary focus of these measurements is to assess the achievable range. The performance of these wireless technologies plays a crucial role in this analysis.enfalseacoustic communicationbuoygatewayIoTLTEradio communicationroutingunderwater networksconference paper
