摘要：Smart phones, tablets, and the rise of the Internet of Things are driving an insatiable demand forwireless capacity. This demand requires networking and Internet infrastructures to evolve to meet the needs of currentand future multimedia applications. Wireless HetNets will play an important role toward the goal of using a diversespectrum to provide high quality-of-ser- vice, especially in indoor environments where most data are consumed. Anadditional tier in the wireless HetNets concept is envisioned using indoor gigabit small-cells to offer additional wirelesscapacity where it is needed the most. The use of light as a new mobile access medium is considered promising. Inthis article, we describe the general characteristics of Wi-Fi and VLC (or LiFi) and demonstrate a practical frameworkfor both technologies to coexist. We explore the existing research activity in this area and articulate current and futureresearch challenges based on our experience in building a proof-of-concept prototype VLC HetNet.
