10 I ICT TODAY 5G WIRELESS: WITH POWERFUL NETWORKS COMES RESPONSIBILITY 5G networks rival optical fiber network performance in wireless. However, with new capability comes the necessity to prevent communications and video stream- ing disruption. Requirements for latency, bandwidth, and reliability for different services must be met. With video surveillance cameras and IoT sensors becoming massive with diverse functions, a new model separating critical functions such as public safety and security is needed. This model is known as network slicing. The network slice pyramid (Figure 2) illustrates the separation of sensors by function including video surveillance. An autonomous car or mission critical communications between first responders, for example, rely on a slice with low latency but not necessarily a high throughput. A streaming media service requires a high throughput and is, therefore, more susceptible to latency. Both traffic control of autonomous vehicles and first responder communications would be delivered over the same ICT network on virtual network slices, thereby optimizing the use of the physical infrastructure. Whether the first responder is law enforcement, fire, EMS, HazMat or Search and Rescue, a stable, reliable and resilient communication network enables effective rescues during emergencies. If a large number of people jump onto social media to send texts, pictures, and videos at the same time during a significant event, service providers maintain connectivity to emergency responders by giving them the "best slice" by assigning them the highest priority access to the 5G mobile network. FWA, then 5G: Bringing Smart City Services to Towns By 2020, 4G LTE, the current leading cellular technology, will cover 63 percent of the world's population but only 37 percent of the landmass. How do we traverse the "last mile" and deliver broadband services that support safe, smart, and connected towns? Fixed wireless access (FWA) extends the internet backbone using wireless mobile network technology rather than fixed fiber optic cable. Sometimes referred to as "last mile," FWA is a telecommunications bridge to a broadband consumption endpoint, usually businesses or homes. 5G FWA uses the high-performance millimeter wave spectrum to simulate "wireless fiber" from point to point.
