• In this presentation we will discuss 5G
wireless systems, better known as 5th
generation mobile technology.
• Mobile wireless industry had started its
technology creation, revolution and evolution
since early 1970’s.
• 5G wireless technology can change the way
we use wireless gadgets by providing very

Vision of 5G wireless technology
• 5G envisions to design a real wireless world,
that is free from obstacles of the earlier
• This requires an integration of networks.
• 5G aims to design a Multi-Bandwidth Data
Path by integrating the current and future
networks for new network architecture of 5G
real wireless world.
• The 5G wireless internet networks are real
wireless world which shall be supported by
CDMA, OFDM, MCCDMA, UWB and IPv6.
• 5G technology has extraordinary data
capabilities and has ability to tie together
unrestricted call volumes and infinite data
broadcast within latest mobile operating
• The Router and switch technology used in 5G
network would provide high connectivity for
5G Terminal 5G Terminal
• 5G Technologies will have an extraordinary
capability to support Software and
• The 5G technology aims to distributes
internet access to nodes across the world
with almost seamless speed.
Features Of 5G Wireless
• 5G technology would offer high resolution for
wireless gadget users and bi-directional large
• The advanced billing interfaces of 5G
technology makes it more attractive and
• The high quality services of 5G technology is
based on Policy to avoid error.
• 5G technology is going to be a new
revolution in wireless systems market.
• As data traffic has tremendous growth
potential, under 4G existing voice centric
telecom hierarchies will be moving flat IP
architecture where, base stations will be
directly connected to media gateways.
• 5G will promote concept of Super Core,
where all the network operators will be
connected one single core and have one
single infrastructure, regardless of their
• 5G will bring evaluation of active infra
sharing and managed services and eventually
all existing network operators will be MVNOs
(Mobile virtual network operators).
