10. OBJECTIVES OF 5G:OBJECTIVES OF 5G:
 5G being developed to accommodate QoS
rate requirements set by further development
of existing 4G applications.
 Flexible channel bandwidth between 5 and
20MHz, optionally up to 40MHz.
 Data rate of at least 1Gb/s between any two
points in the world.
 Increase system spectral efficiency of up to
3bit/s/Hz/cell in the downlink and
2.25bit/s/Hz/cell for indoor usage.

11. KEY CONCEPTS OF 5GKEY CONCEPTS OF 5G
 Real wireless world with no more limitation with access and
zone issues.
 Wearable devices with AI capabilities.
 Internet protocol version 6 (IPv6), where a visiting care-of
mobile IP address is assigned according to location and
connected network.
 One unified global standard.
 Pervasive networks providing ubiquitous computing: The user
can simultaneously be connected to several wireless access
technologies and seamlessly move between them
 Cognitive radio technology, also known as smart-radio:
allowing Different radio technologies to share the same
spectrum efficiently.
 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. 11

Flat IP architectures
• Reduce the number of network elements in
the data path to lower operations costs and
capital expenditure.
• Partially decouple the cost of delivering
service from the volume of data transmitted to
align infrastructure capabilities with emerging
application requirements.
• Minimize system latency and enable
applications with a lower tolerance for delay;
upcoming latency enhancements on the radio
link can also be fully realized.

13. June 23, 2015 13
• Evolve radio access and packet core
networks independently of each other to a
greater extent than in the past, creating
greater flexibility in network planning and
deployment.
• Develop a flexible core network that can
serve as the basis for service innovation
across both mobile and generic IP access
networks
• Create a platform that will enable mobile
broadband operators to be competitive, from
a price /performance perspective, with wired
networks.

Cognitive Radio or Software Define Radio
This new radio technologies share the same spectrum
efficiently by finding unused spectrum and adapting the
transmission scheme to the requirements of the
technologies currently sharing the spectrum.
Cognitive radio will have knowledge of free channel
and occupy channel, type of data to be transmitted,
modulation scheme, position of receiving equipment
and also aware of the environment.

Beam Division Multiple Access
In BDMA technique base station allocates separate beam
to each mobile station for that it divides the antenna beam
according to the location of mobile stations. This multiple
access technique significantly increases the capacity of
the system.
In BDMA technique,
multiple beams of
distinct patterns are
formed using the
phase array
antenna.

16. IPv6 SUPPORT:IPv6 SUPPORT:
 IPv6 increases the IP addresses size from 32bit to 128
bits, to support more levels of addressing hierarchy and
much greater number of addressable node.
 IPv6 support large number of wireless enabled devices.
 IPv6 Extend the IP address space enough to offer a
unique IP address to any device.
 IPv6 Improve support for IP Mobility.
 IPv6 addresses are 128 bit, which is four times more
than 32 bit IPv4 address.

4G convergence architecture Mix bandwidth data path model
5G is real wireless world, it is complete wireless communication.
We design mix-bandwidth data path for 5G so that all wireless
network resource can be used efficiently
This model based on any two networks overlay area.
When a mobile node comes into the overlay area, both of the
two networks can supply services for the mobile node
simultaneously.
Data request can be sent from any one network, and reply can
be from any other network.

MN request can
go through the
First connection
(MN → BS → PDSN →
CN)
the resulting reply
can
come from the
second connection
(CN → PDSN → AP →
MN).
and
Thus, two networks supply services for the
mobile node simultaneously
