Novel Indoor Ultraviolet Wireless Communication: Design Implementation, Channel Modeling, and Challenges

Ultraviolet (UV) wireless communication has recently received much attention only for outdoor applications. Due to inherent nature of UV transmission, we believe that UV can also be considered for efficient and low-cost indoor communications. In this article, we present a novel UV indoor communication with an in-depth description of design implementation, channel modeling, and performance analysis. We consider a discrete Poisson channel with transmit power constraints. While focusing mainly on the development of a UV-based indoor communication, an indoor UV channel model is first proposed. Based on this, physical characteristics of the UV indoor channel using on-off keying modulation are analyzed with direct detection in terms of bit error rate, channel dc gain, and delay spread. As the proposed UV indoor communication exhibits some limitations, we provide a brief discussion on design implementation and challenges. From the performance analysis, it is found that the proposed UV indoor communication can provide ubiquitous link connectivity in indoor applications, while keeping network structure and management simple.
