3.  In telecommunications, 5G is the fifth generation
technology standard for broadband cellular
networks, which cellular phone companies began
deploying worldwide in 2019, and is the planned
successor to the 4G networks which provide
connectivity to most current cellphones. It will help
redefine the network, establishing a new global
wireless standard for speed, throughput and
bandwidth. A 5G network builds a bridge to the
future.

4. 1G
The first analog cell
phones enter the world.
2G
New features like SMS and
voicemail come to mobile
handsets.

5. 3G
Higher data transfer rates
enable mobile web
browsing, image sharing
and GPS location-tracking.
4G
Broadband delivers deep
web functionality to our
smartphones.

6.  5G is the fifth generation of
wireless technology. But users will
know it as one of the fastest, most
robust technologies the world has
ever seen.
 That means quicker downloads,
much lower lag and a significant
impact on how we live, work and
play. The connectivity benefits of
5G are expected to make businesses
more efficient and give consumers
access to more information faster
than ever before. Connected
cars, smart communities, industrial
IoT, immersive education—they all
will rely on 5G networks.

7.  To understand 5G, it’s helpful to understand what came before it.
Broadly, the first generation of mobile technology, 1G, was about
voice. The ability to use a phone in a car, or anywhere else, really
took root here. The advent of 2G introduced a short-messaging
layer—pieces of which can still be seen in today’s texting
features. The move to 3G provided the essential network speeds
for smartphones. And 4G, with its blazing data-transfer rates,
gave rise to many of the connected devices and services that we
rely on and enjoy today.
 This is all predicated on work we began years ago to “densify”
our 4G LTE network with small cell sites in high traffic areas—
places like shopping centers and college campuses, as well as
downtown areas. Thanks to these improvements, as well as
using millimeter wave spectrum and deploying a massive fiber
network.

Understanding 5G technology

9.  5G is based on OFDM (Orthogonal frequency-division
multiplexing), a method of modulating a digital signal
across several different channels to reduce interference. 5G
uses 5G NR air interface alongside OFDM principles. 5G
also uses wider bandwidth technologies such as sub-6 GHz
and mmWave.
 Like 4G LTE, 5G OFDM operates based on the same
mobile networking principles. However, the new 5G NR air
interface can further enhance OFDM to deliver a much
higher degree of flexibility and scalability. This could
provide more 5G access to more people and things for a
variety of different use cases.

10. 1. Millimeter Waves
2. Smart Cell
3. Massive MIMO
4. Beamforming
5. Full Duplex

11. The problem is that the
commonly used
frequencies below 5
GHz are already
extremely crowded, so
where can we find new
spectrum resources?
5G's use of millimeter
waves uses the second of
the two methods to
increase transmission
speeds.

12.  As millimeter waves
cannot travel through
obstacle, to tackle the
problem of lack of
connectivity in crowded
areas, smart cell towers
are introduced.
 These towers are placed
in different areas keeping
in mind the crowded parts
so as to maintain the
continuity of networks

13.  Massive MIMO — which is an
extension of MIMO —
expands beyond the legacy
systems by adding a much
higher number of antennas on
the base station. The
“massive” number of antennas
helps focus energy, which
brings drastic improvements in
throughput and efficiency.
Along with the increased
number of antennas, both the
network and mobile devices
implement more complex
designs to coordinate MIMO
operations.

15.  Today's base stations and
cellphones rely on transceivers
that must take turns if
transmitting and receiving
information over the same
frequency, or operate on different
frequencies if a user wishes to
transmit and receive information
at the same time.
 With 5G, a transceiver will be
able to transmit and receive data
at the same time, on the same
frequency. This technology is
known as full duplex, and it could
double the capacity of wireless
networks at their most
fundamental physical layer

16. The previous generations of mobile
networks are:
 First generation - 1G
1980s: 1G delivered analog voice.
 Second generation - 2G
Early 1990s: 2G introduced digital
voice (e.g. CDMA)
 Third generation - 3G
Early 2000s: 3G brought mobile
data (e.g. CDMA2000).
 Fourth generation - 4G LTE
2010s: 4G LTE ushered in the era
of mobile broadband.
1G, 2G, 3G, and 4G all led to 5G,
which is designed to provide more
connectivity than was ever available
before.

17. Broadly speaking, 5G is used across three main services:
1. Enhanced mobile broadband
In addition to making our smartphones better, 5G mobile
technology can usher in new immersive experiences such as
VR and AR with faster, more uniform data rates, lower latency,
and lower cost-per-bit.
2. Mission-critical communications
5G can enable new services that can transform industries with
ultra-reliable, available, low-latency links like remote control
of critical infrastructure, vehicles, and medical procedures.
3. Massive IoT
5G is meant to seamlessly connect a massive number of
embedded sensors in virtually everything through the ability to
scale down in data rates, power, and mobility—providing
extremely lean and low-cost connectivity solutions.

18. Advantages Disadvantages
 High resolution and bi-directional
large bandwidth shaping.
 Technology to gather all networks on
one platform and is more effective
and efficient.
 Most likely, will provide a huge
broadcasting data (in Gigabit), which
will support more than 60,000
connections.
 Technological sound to support
heterogeneous services and provide
uniform, uninterrupted, and
consistent connectivity across the
world.
 Technology is still under process
and research on its viability is
going on.
 The speed, this technology is
claiming seems difficult to achieve
(in future, it might be) because of
the incompetent technological
support in most parts of the world.

19.  Yes, 5G is already here today, and global operators started
launching new 5G networks in early 2019. Also, all major phone
manufacturers are commercializing 5G phones. And soon, even
more people may be able to access 5G.
 5G has been deployed in 60+ countries and counting. We are
seeing much faster rollout and adoption compared with 4G.
Consumers are very excited about the high speeds and low
latencies. But 5G goes beyond these benefits by also providing
the capability for mission-critical services, enhanced mobile
broadband and massive IoT. While it is hard to predict when
everyone will have access to 5G, we are seeing great momentum
of 5G launches in its first year and we expect more countries to
launch their 5G networks in 2020 and beyond.
