The communication era has witnessed a
distinctive evolution; from networks handling analog voice services to fully IP-enabled
mobile networks. The first mobile generation (1G) was a revolution supporting
user mobility after the fixed telecom network. New services have emerged with
newer versions. With the second digital mobile generation (2G), new services
and applications have emerged (i.e. text messaging). However, with the third
and fourth generations (3G and 4G), distinctive applications have appeared
(apple Siri, google glass, etc.) paving the way towards new mobile
telecommunication epoch. Cell phones will dominate the future Internet 146. “Horizon 2020 and beyond” is the
tag of the upcoming new era in the telecommunication domain. 5G is not depicted
to be an evolution of the previous mobile network generations (2G/3G/4G (LTE)).
It is more of a revolution that will change our way of life. 5G is supposed to
be the second industrial revolution. Very low latency, high throughput,
reliability, security, and high mobility are the characteristics of this
upcoming technology 147. This revolution will enable the cellular IoT
paradigm 148. Main IoT requirements are to be met by this
new mobile network. IoT is
expected to be integrated in the 5G mobile network 149. The no cell communication pattern will be
supported encompassing the Device-to-Device (D2D) direct communication reducing
the signaling and connection time. There is an effort to integrate Machine Type
Communication (MTC) into the 3GPP mobile network architecture supporting
essentially Human-to-Human (H2H) communication. The mobile network capacity to
handle mobile wireless communication makes it suitable for the new emerged
communication type. However, the high number of connected devices will need a new
management paradigm. Overhead in terms of signaling and communicated data must
be considered in any mobile network bearing M2M based services.
