Abstract

As the world has become an increasingly connected ecosystem, data demand has continually pushed the limits of our wireless networks. Each generation of wireless technology has added extensive wireless capacity; however, novel use cases and technological adoption have continually raised the demand at rates previously unseen. This trend continues today as massive data downloads, video streaming, augmented reality, and the Internet of Things push the limits of 4G networks. Furthermore, increasing application complexity and demand per device is paired with an increasing number and density of wireless devices. Hence, the wireless communications industry is challenged to meet an extreme growth in data traffic in the coming years—a demand growth that is unlikely to be met with iterative modifications to the current infrastructure. With this in mind, the world mobile and wireless infrastructure community is looking toward the 5th generation of mobile telecommunications, or 5G, with the expectation that new technologies will be adopted which drastically alter the conventional view of wireless networks [1]. Although 5G has been described as the solution for demands of 2020 and beyond, global standardization efforts have been limited. Given the wide variety of devices, applications, and services expected to be part of next generation networks, the vision for 5G has been defined in several ways [24]. Figure 13.1 depicts a set of proposed 5G design principles that relate to the integration of visible light communication (VLC) within the next generation wireless communications landscape. These concepts and their relationship to VLC are described throughout this chapter.
