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 streaming
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.
