5G is the fifth-generation wireless
broadband technology that is based on the IEEE
802.11ac
standard. The network expandability is increased up to hundreds of thousands of
connections.

The signal technology of 5G has also been improved for greater coverage as
well as spectral and signalling efficiency. These improvements stand to further
enable changes like pervasive
computing and the Internet of Things (IoT) 1.

As 5G is in the stage of development, it is not open
for use by anyone. However, lots of companies have started creating 5G products
and testing them. Many advancements have come from companies like Nokia, Qualcomm,
Samsung, etc with upcoming companies forming partnerships and pledging money to
continue the research in 5G technology and its applications 2.

As the demand for mobile broadband is increasing
continuously, 5G will become the next major phase in mobile communications standards.
Today, the features that are in demand for running new applications that require
massive broadband capabilities are high network speeds and low latency. So, the
driving forces for the 5G evolution are speed and latency.

Tele-Communication companies like Ericsson and NTT
Docomo have predicted that the first 5G networks would arrive by 2020, but for
the deployment of 5G technology it may take until 2030.

The expectations of 5G technology are

Better and faster coverage: It would be deployed with
the help of base stations fixed at small distanced gaps on post lamps etc.
unlike 4G where the base stations were placed at fixed positions, for
handling cellular traffic over a wide area. This model would enable
better coverage and put an end our broadband miseries.Low Latency: Latency is typically the
time lag between a packet of data to reach from its source to the
designated site. With the advent of 5G, latency should be reduced
significantly compared to LTE.Increased Capacity: Network capacity is the
maximum capacity of a network path for sending packets of data from source
to destination. While LTE has a theoretical capacity of 100 Mbps, for
downloading data and about 50 Mbps for uploading, 5G should be able to
bring about better network capacity to meet the increased demand for data
and allow seamless connection for services to be run in future.Convenience: 5G is expected to provide
new experiences of convenience, backed with ultimate connectivity. All
devices would share information readily and work in sync in order to
enhance users’ convenience, entertainment, productivity, etc.Increased Scalability: 5G technology is going to be
scalable to extreme variations. It will enhance the existing speed and
efficiency by scaling up to connect the Internet of Things and enable new
types of services 3.

The future enhancement of 5G technology is with the incorporation
of Nano-core integrated with artificial intelligence(AI). Also, 6G technology,6G
network, 6G wiki, etc are getting familiar with the evolution of new mobile
technologies. After 5G is adopted, 6G will come into the mobile world. 6G will
include the relevant technologies that is out of scope in 5G technology 4.
For example, users may demand and expect massive global coverage, higher
capacities, etc and 6G will be expected to include all these demands of the
users.

Many of the cellular devices connected nowadays are machines (IoT) rather
than people, with the rise of Smart Homes, Smart Building and Smart Cities, so
5G and 6G will include increased demands for machine-to-machine communications,
including robotic and autonomous drone delivery and transport systems. The
Internet-of-Everything (IoE) is a related development 5.
