This paper discusses a novel idea for transmission of voices in real time, underwater so that the system can be used by the deep sea divers for both lightning and data transfer applications simultaneously. Experiments were performed using white light, green and blue light respectively to transfer voice in real time in a water tank and the graphs were obtained. Based on the comparison study, we make recommendations for the selection of the right colour of light for communication efficiency in specified underwater environments.

“…Valuable efforts have been invested in surveying this field [9]- [20]. To elaborate, a brief survey [9] of VLC systems was published in 2010, which discussed the VLC techniques and their applications in their early development phase. Tsonev et al [10] discussed some of the key networking techniques required for realizing light fidelity (Li-Fi) networks, including the associated multiple access techniques, the potential uplink solutions as well as the optical attocell and overall network structure.…”

Abstract-In order to counteract the explosive escalation of wireless tele-traffic, the communication spectrum has been gradually expanded from the conventional radio frequency (RF) band to the optical wireless (OW) domain. By integrating the classic RF band relying on diverse radio techniques and optical bands, the next-generation heterogeneous networks (HetNets) are expected to offer a potential solution for supporting the ever-increasing wireless tele-traffic. Owing to its abundant unlicensed spectral resources, visible light communications (VLC) combined with advanced illumination constitute a competent candidate for complementing the existing RF networks. Although the advantages of VLC are multi-fold, some challenges arise when incorporating VLC into the classic RF HetNet environments, which may require new system architectures. The user-centric (UC) design principle for VLC environments constitutes a novel and competitive design paradigm for the super dense multi-tier cell combinations of HetNets. The UC concept may be expected to become one of the disruptive techniques to be used in the forthcoming fifthgeneration era. This paper provides a comprehensive survey of visible-light-aided OW systems with special emphasis on the design and optimization of VLC networks, where the radically new UC design philosophy is reviewed. Finally, design guidelines are provided for VLC systems.

Abstract. This paper designs an indoor visible light communication application system based on LED. The system can modulate the original signal one or more times, move to a specific frequency band, transmit on the power line, in the LED terminal use this module to decode, restore the Ethernet signals. This design is applicable to the simplicity of the LED visible light communication applications, which provide the premise and guarantee for the construction of smart home network.
