FIG. 5.12 Possible application and service samples for 5G cellular communication systems.

l Full coverage
l 99.999% availability
l 90% reduced energy consumption
l 1000-fold more bandwidth opportunity per unit area
l 1–10 Gbps data rates for entire components of the network
l Longer battery life as much as 10 years
l Providing service to about 100 times more devices
l 1 ms end-to-end (E2E) latency
The key requirements of new generation cellular systems are also summarized
in Fig. 5.13. The 5G systems have to overcome forthcoming user traffics which
will be larger and more complex than present networks. This problem is con-
sidered as one of the important challenges of dense network systems. In order
2
to support growing user traffics, providing 1000x system capacity per km than
4G systems is aimed in 5G systems. Another significant need is to provide
higher data speed than that of the 4G networks. In the event of improvement
of cloud systems and dense content applications are considered, the 5G cellular
systems not only should ensure better quality of the user experience (QoE) but
also should intent to present higher data rate services. The next generation wire-
less communication systems should allow plenty devices to be connected to the
network in order to ensure better assistance [51, 60].
Cellular communication systems are regarded as one of the key technologies
for SG applications such as smart metering, phasor measurement unit, smart
energy management, and remote monitoring [61]. Reliability, security, latency,
and entire performance requirements of SG applications can be supported by
