5G
Mobile Technology
5G technologies will change the
way most high bandwidth users access their phones. With 5G pushed over a
VOIP-enabled device, people will experience a level of call volume and data
transmission never experienced before.5G technology is offering the services in
Product Engineering, Documentation, supporting electronic transactions
(e-Payments, e transactions) etc. As the customer becomes more and more aware
of the mobile phone technology, he or she will look for a decent package all
together, including all the advanced features a cellular phone can have. Hence
the search for new technology is always the main motive of the leading cell
phone giants to out innovate their competitors. The ultimate goal of 5G is to
design a real wireless world that is free from obstacles of the earlier
generations. This requires an integration of networks. 5G Technology stands for
5th Generation Mobile technology. 5G technology has changed the means to use
cell phones within very high bandwidth. 5G is a packet switched wireless system
with wide area coverage and high throughput. 5G wireless uses OFDM and
millimeter wireless that enables data rate of 20 mbps and frequency band of 2-8
GHz. 5G is going to be a packed based network . The 5G communication system is
envisioned as the real wireless network, capable of supporting wireless World
Wide Web (wwww) applications in 2010 to 2015 time frame. There are two views of
5G systems: evolutionary and revolutionary. In the evolutionary view the 5G (or
beyond 4G) systems will be capable of supporting wwww allowing a highly
flexible network such as a Dynamic Adhoc Wireless Network (DAWN). In this view
advanced technologies including intelligent antenna and flexible modulation are
keys to optimize the adhoc wireless networks. In revolutionary view 5G systems
should be an intelligent technology capable of interconnecting the entire world
without limits. An example application could be a robot with built-in wireless
communication with artificial intelligence. User never experienced ever before
such a high value technology. The 5G technologies include all type of advanced
features which makes 5G technology most powerful and in huge demand in near
future. Amazing isn’t it such a huge collection of technology being integrated
into a small device. The 5G technology provides the mobile phone users more
features and efficiency than the 1000 lunar module. A user of mobile phone can
easily hook their 5G technology gadget with laptops or tablets to acquire
broadband internet connectivity. Up till now following features of the 5G
technology have come to surface- High resolution is offered by 5G for extreme
mobile users, it also offers bidirectional huge bandwidth.- 5G technology’s
excellent quality service is based on Policy in order to evade errors.- It
provides transporter class type gateway that has unequalled steadiness.- The 5G
technology’s billing interface is highly advanced making it efficient and
appealing.- It offers huge quantity of broadcasting data, which is in Giga
Bytes, sustaining more than 60,000 connections.- This technology also provides
remote diagnostic feature.- Provides up to 25 megabytes per second
connectivity. Also it supports the private virtual networks.
KEY CONCEPTS OF 5G
The key concepts discussing 5G
and beyond 4G wireless communications are:
1) Real wireless world with no
more limitation with access and zone issues.
2) Wearable devices with AI
capabilities.

6(IPv6), where a visiting care-of mobile IP address is assigned according to Location and connected network.
4) One unified global standard.
5) Pervasive networks providing
ubiquitous computing: The user can simultaneously be connected to several
wireless access technologies and seamlessly move between them These access
technologies can be a 2.5G, 3G, 4G or 5G mobile networks, Wi-Fi, WPAN or any
other future access technology. In 5G, the concept may be further developed
into multiple concurrent data transfer paths.
6) Cognitive radio technology,
also known as smart radio: allowing different radio technologies to share the
same spectrum efficiently by adaptively finding unused spectrum and adapting
the transmission scheme to the requirements of the technologies currently
sharing the spectrum. This dynamic radio resource management is achieved in a
distributed fashion, and relies on software defined radio.
7) High altitude stratospheric
platform station (HAPS) systems. The radio interface of 5G communication
systems is suggested in a Korean research and development program to be based
on beam division multiple access (BDMA) and group cooperative relay techniques.

HARDWARE AND SOFTWARE
5G HARDWARE
1) UWB Networks: higher bandwidth
at low energy levels. This short-range radio technology is ideal for
Wireless personal area networks
(WPANs). UWB complements existing longer range radio technologies – such as
Wi-Fi,* WiMAX, and cellular wide area communications – that bring in data and
communications from the outside world. UWB provides the needed cost-effective,
power-efficient, high bandwidth solution for relaying data from host devices to
devices in the immediate area (up to 10 meters or 30 feet).
2) Bandwidth: 4000 megabits per
second, which is 400 times faster than today’s wireless networks.
3) Smart antennasa. Switched Beam
Antennas: Switched Beam Antennas support radio positioning via Angle of Arrival
(AOA) information collected from nearby devices. b. Adaptive Array Antennas:
The use of adaptive antenna arrays is one area that shows promise for improving
capacity of wireless systems and providing improved safety through position
location capabilities. These arrays can be used for interference rejection
through spatial _altering, position location through direction _ending
measurements, and developing improved channel models through angle of arrival
channel sounding measurements.
4) Multiplexing: CDMA (Code
Division Multiple Access) CDMA employs analog-to-digital conversion (ADC) in
combination with spread spectrum technology. Audio input is first digitized
into binary elements. The frequency of the transmitted signal is then made to
vary according to a defined pattern (code), so it can be intercepted only by a
receiver whose frequency response is programmed with the same code, so it
follows exactly along with the transmitter frequency. There are trillions of
possible frequency-sequencing codes, which enhance privacy and makes cloning
difficult.
5G
SOFTWARE
1) 5G will be single unified
standard of different wireless networks, including wireless technologies (e.g.
IEEE 802.11), LAN/WAN/ PAN and WWWW, unified IP and seamless combination of
broad band.
2) Software Defined Radio, Packet
layer, implementation of packets, encryption, flexibility etc. ref:
CONCEPTS FOR 5G MOBILE NETWORKS
The 5G terminals will have software
defined radios and modulation schemes as well as new error-control schemes that
can be downloaded from the Internet. The development is seen towards the user
terminals as a focus of the 5G mobile networks. The terminals will have access
to different wireless technologies at the same time and the terminal should be
able to combine different flows from different technologies. The vertical
handovers should be avoided, because they are not feasible in a case when there
are many technologies and many operators and service providers. In 5G, each
network will be responsible for handling user-mobility, while the terminal will
make the final choice among different wireless/mobile access network providers
for a given service. Such choice will be based on open intelligent middleware
in the mobile phone.
5G MOBILE NETWORK ARCHITECTURE
Below figure shows the system
model that proposes design of network architecture for 5G mobile systems, which
is all-IP based model for wireless and mobile networks interoperability. The
system consists of a user terminal (which has a crucial role in the new
architecture) and a number of independent, autonomous radio access
technologies. Within each of the terminals, each of the radio access
technologies is seen as the IP link to the outside Internet world. However,
there should be different radio interface for each Radio Access Technology
(RAT) in the mobile terminal. For an example, if we want to have access to four
different RATs, we need to have four different accesses – specific interfaces
in the mobile terminal, and to have all of them active at the same time, with
aim to have this architecture to be functional. Applications and servers
somewhere on the Internet. Routing of packets should be carried out in
accordance with established policies of the user.
