2. ABSTRACT:
• The paper presents the generation of cellular network are change from one to another has
been driven by hardware technology advancement.The revolution from 4g to 5g is different
because of software technology with the advents of these software and unexpected levels of
computational capacity the vision of autonomous network management can be put into
practice taking knowledge of self monitoring in the area of networks using software defined
networks .SDN uses self healing techniques to get self recovery of software self healing of
board faults self monitoring of network.
• SDN has emerged as a new intelligent architecture for network architecture to reduce
hardware
limitation.The ultimate goal of SDN is to create a 5G network that doesn’t need any design or
adjustments of the administrator interfaces so network which is fully automated.

5. EVOLUTION FROM 1G TO 4G
• The evolution is based on the four main key aspects :
• Radio access,
• Data rates,
• Bandwidth and
• Switching schemes.
6. FIRST GENERATION SYSTEMS (1G)
• Developed in 1981
• Based on analog system
• Speed up to 2.4 kbps
• Allows user to make voice calls in 1 country
7. SECOND GENERATION SYSTEMS (2G)
• Developed in 1992
• Based on digital system
• Speed up to 64 kbps
• Services such are digital voice &
• SMS with more clarity
• Semi global facility
• 2G are the handsets we are using today, with 2.5G having more capabilities
8. THIRD GENERATION SYSTEMS (3G)
• Developed in 2001
• Speed up to 2 Mbps
• Superior voice quality
• Good clarity in video conference
• E-mail, PDA, information surfing, on- line shopping/ banking, games,
etc.
• Global roaming
9. FOURTH GENERATION SYSTEMS (4G)
• Developed in 2010
• Faster & more reliable
• Speed up to 50 Mbps
• High performance
• Easy roaming
• Low cost
10. INTRODUCTION TO 5G
• 5G Wireless: 5th generation wireless technology
• Complete wireless communication with almost no limitations
• Can be called REAL wireless world
• Has incredible transmission speed
11. KEY CONCEPTS OF 5G
• Real wireless world with no more limitation with access and zone issues.
• The user can simultaneously be connected with several wireless access
technology
• Smart radio
• Suitable devices
• IPv6, where a visiting care of mobile IP address is assigned according to
location & connected network

13. WHAT IS SDN?
• Software-defined networking (SDN) is an architecture that aims
to make networks agile and flexible. The goal of SDN is to
improve network control by enabling enterprises and service
providers to respond quickly to changing business requirements.
• In a software-defined network, a network engineer or
administrator can shape traffic from a centralized control console
without having to touch individual switches in the network. The
centralized SDNcontroller directs the switches to deliver network
services wherever they're needed, regardless of the specific
17. SELF-HEALING
• Features for automatic detection and removal of failures and automatic
adjustment of parameters.
• Coverage and Capacity Optimization enables automatic correction of
capacity problems depending on slowly changing environment, like seasonal
variations.
• Minimization of drive tests (MDT), is enabling normal UEs to provide the
same type of information as those collected in drive test. A great advantage
is that UEs can retrieve and report parameters from indoor environments.
18. SELF-CONFIGURATION
• This is the dynamic plug-and-play configuration of newly deployed eNBs. The eNB
will by itself configure the Physical Cell Identity, transmission frequency and power,
leading to faster cell planning and rollout.
•SELF-OPTIMISATION
• Functions for self-optimisation are mainly . It includes optimisation of coverage,
capacity, handover and interference.
• Mobility load balancing (MLB) is a function where cells suffering congestion can
transfer load to other cells, which have spare resources. MLB includes load
reporting between eNBs to exchange information about load level and available
capacity.
