5G networks will provide extremely high data rates, greater coverage through dense base station deployment, higher capacity, lower latency and improved quality of service. 5G will enable broadband connectivity anywhere and allow connection of a massive number of devices like those in the Internet of Things. During the next decade, 4G and 5G technologies will likely co-exist to support a smooth transition as 4G knowledge is utilized for 5G network deployment. However, 5G also presents security risks that will need to be addressed through adequate security measures, regulations and standards.

2. 5G wireless networks have envisioned to provide
extremely high data rates, higher coverage through
dense base station deployment with increased
capacity, significantly better Quality of Service
(QoS), and extremely low latency.
5G may provide broadband access everywhere,
entertain higher user mobility, enable connectivity
of a massive number of devices (e.g. IoT). It is
anticipated that the connectivity will be
ultra‐reliable and affordable.

3. The development of IP‐based communication, for
4G, has helped to develop new business
opportunities, provide new online services, and
connect industrial machines, home appliances and
business units. The Presenter of this talk is of the
opinion that for smooth transition, 4G and 5G
technologies must co-exist during the next decade
and 4G knowledge base of IP telephony can be
utilized for deployment of 5G network to optimize
business processes.

4. Countries such as China, UK and USA are
adapting aggressive approach to acquire this
technology on a priority basis therefore stakes are
higher on the issues such as spectrum acquisition
and infrastructure design and implementation.
Canada has offered a significant contribution for
LTE and fiber optics technologies through vendors
such as Rogers and Bell but current influx by
Huawei through its technology knowledge,
hardware and supporting software and human
resources presents a challenge to North Americas
communication infrastructure and integrity and

6. What is 5G 1/2
5th generation mobile network is designed to
meet the very large growth in data and
connectivity of today’s modern society, the
internet of things with billions of connected
devices, and tomorrow’s innovations.
• Higher multi-Gbps
• Peak data speeds
• Ultra low latency (Delay)

7. What is 5G 2/2
• More reliability
• Massive network capacity
• Increased availability
• Uniform user experience to more users

9. Main Components of 5G
9
A mobile network has two main components:
• Radio Access Network: It consists of various
types of facilities including small cells, towers,
masts and dedicated in-building and home
systems that connect mobile users and wireless
devices to the main core network.
• Core Network: It is the mobile exchange and
data network that manages all of the mobile
voice, data and internet connections.

11. Millimeter 5G Spectrum
11
Existing Mobile networks work in the spectrum
ranging from 1 to 6 GHz. New mobile spectrums
will range from 30 to 100 GHz. These bands will
provide significantly more capacity compared to
the current mobile technologies.
Benefits of additional spectrum are:
• Greater capacity
• More users
• Bulk data
• Faster connections

14. 5G Additional Components
5G networks frequencies have a very short
connection range and need additional
components to work in conjunction with 4G
networks using:
• Macro cells
• Small cells
• Dedicated in-building systems.

16. 5G Antennas
16
5G will use ‘massive’ MIMO (multiple input,
multiple output) antennas that have very
large numbers of antenna elements or
connections to send and receive more data
simultaneously. The benefit to users is that
more people can simultaneously connect to
the network and maintain high throughput.
5G User Equipment including mobile
phones and devices will also have MIMO
antenna technology built into the device for

• Unauthorized access or usage of assets
• Traffic embezzlement due to recursive/additive
virtualization
• Insufficient technology level readiness
• Difficulties to regulation compliance
• Trust Management Complexity
• Provisions to facilitate change of service

• Security Level
• Security Automation
• Security Monitoring
• Security Management
• 5G regulation conformity
• Enabling Value Added Services with end to

20. Take Away
5G Technology offers great incentives but they
also come with prices associated to it.
We are offered high connectivity, unmatchable
data rates, near to none delays. But at the
same time we will be spending enormous
resources on infrastructure, data encryption
and enforcing regulations. Data integrity and
privacy can also become an issue. We are
anticipating full inception of 5G by 2025.
IS IT WORTHY!!
YES/NO
