1) 5G technology is the next generation of mobile networks that will provide significantly higher bandwidth and connectivity compared to previous generations. It aims to support up to 1 terabit per second data speeds and nearly instantaneous connectivity. 2) 5G faces many challenges to achieve its goals, such as providing 1000 times greater wireless capacity, 90% reduced energy usage per service, and seamless connectivity between vast numbers of wireless devices. 3) While 5G specifications are still being developed, it is expected to enable new applications through ultra-fast speeds and connectivity between devices, people, and smart infrastructure. Many countries are heavily investing in 5G research due to its projected high demand and potential economic impact.

Background:
Wireless communication has started in early 1970s. In next four decades, a mobile wireless
technology has evolved from 1G to 5G. From 1G to 2.5G and from 3G to 5G this world of
telecommunication has seen a number of improvements along with improve performance with
every passing day. This fast revolution in mobile computing changes our day to day life that is
way we work, interact, learn etc.
Currently, there is a dramatic change of the mobile communication landscape. Today’s most of
the applications are data hungry which requires more bandwidth and some emergency conditions
requires M2M connectivity with large number of connected devices with extreme low latency.
Although 4G can fulfill many of these requirements but there are significant limitations of limits
in network capacity and latency limit (>20ms) lying in the applied methods and system structure.

2. 5G Technology stands for 5th Generation Mobile technology. 5G
mobile technology has changed the means to use cell phones within
very high bandwidth. User never experienced ever before such a high
value technology. Nowadays mobile users have much awareness of
the cell phone (mobile) technology. The 5G technologies include all type of advanced features
which makes 5G mobile technology most powerful and in huge demand in near future.
In 5G transmission techniques are further advancing with increased in signal processing
capabilities and availability of modern components like amplifier, mixers etc. which allows cost
efficient use on higher frequency bands (>10GHz). In consequence, many research activities
have been started in Europe, North America and Asia on next generation mobile communication
system. So far, the meaning of 5G is not fully defined and target is around 2020.
Fifth generation researches are being made on development of World Wide Wireless Web
(WWWW), Dynamic Adhoc wireless networks (DAWN) and Real Wireless World. Fifth
generation focus on VOIP-enabled devices that user will experience a high level of call volume
and data transmission. Fifth generation technology will fulfill all the requirements of customers
who always want advanced features in cellular phones. The main features in 5G mobile network
is that user can simultaneously connect to the multiple wireless technologies and can switch
between them. This forthcoming mobile technology will support IPV6 and flat IP.
5G Networks Technical Objectives:
Technically after the implementation of 5G networks we can expect high connectivity up to
1Tbps, extraordinary data capabilities & connectivity, zero-distance connectivity between
peoples and more dialing speed.

3. Migrating Challenges towards 5G
5G networks should have should capabilities to encapsulate all the contemporary issues related
to fast changing technology, limited scarce resources and demand. Some of them are listed
below:
 1000 times higher wireless area capacity and more varied service capabilities.
 Saving up to 90% of energy per service.
 “Zero perceived” downtime for service provision.
 Very dense deployments of wireless communication.
 Enabling advanced user controlled privacy.
 Flexible backhaul solutions.
 Versatile ubiquitous radio access infrastructure.
 Addressing management complexity/heterogeneity.
 Increase user perceived QoS.
 Integration of wireless/optical network.
Conclusion:
Although there are already some 5G-relevant documents defining the technical specifications,
the research on 5G is still at its initial stage. Looking into the future development of computer,
network and communication technologies, 5G is expected to be the future architecture of
wireless networks aiming to build a virtual, configurable and intelligent mobile communication
system.
5G technology is the upcoming technology with very high bandwidth and higher data transfer
rate. Many big countries are investing huge amount of money on this project as it was having
high demand in the future. Thusly, it will satisfy the growing solicitation of rising big-data,
cloud, machine-to-machine and diverse applications.
