2. What is Wireless
Communication?
• In 1895, Guglielmo Marconi succeeded in receiving
Morse code on a radio wave transmitted by a
spark-gap transmitter with a receiver 2.4 km away.
This experiment demonstrated the basic concept
and framework of wireless communication today.
• In 1981, the first analog cellular system, “Nordic
Mobile Telephone (NMT)”, was introduced and this
was soon followed by the Advanced Mobile Phone
Service (AMPS) in North America in 1983. In 1988,
the first digital cellular system “Global System for
Mobile (GSM)” was introduced into Europe
• The G in these labels simply stands for ‘generation’.

3. Significance of Wireless
Communication.
There are many advantages of Wireless
Communication given as:
• Cost effectiveness
• Flexibility
• Convenience
• Speed
• Accessibility
• Constant connectivity

4. Evolution of Mobile
Networks:
• First Generation(1G) Technology
• 1G technology provided analogue cellular service, and it was developed
early 1980s. It allowed users to make mobile phone calls, sending and
receiving a signal via radio frequencies. It also allowed for two-way
communication.
• Features of 1g Technology
•
• The main feature of 1G technology was the ability to make calls from
location. Because of this, it has become popular for both personal and
use.
• Furthermore, it offered a great deal of convenience for people who
needed to stay connected on the go.
• The transmission speeds of 1G technology were quite low, usually
at 9.6 kbps. This meant that data usage was limited, and it wasn’t
more complex applications.

5. Second Generation(2G) Technology
• 2G, or the Second Generation of wireless
technology, was a revolutionary leap forward
compared to 1G. It was introduced in the early
1990s and allowed data transfer speeds up to 64
Kbit/s. 2G also enabled the first digital mobile
phones and text messaging. 2G allowed users to
make voice calls and send text messages, but it
was limited to those two features.

6. Features of 2g Technology
• 2G technology was based on GSM (Global System for Mobile
Communications) which allowed for digital encryption of communications.
• 2G also made it possible for phone networks to track the exact location of
a user and allowed roaming between different networks.
• 2G also allowed for the development of mobile internet and mobile
commerce.
• 2G technology was instrumental in the development of the modern mobile
phone and although it has been largely replaced by 3G and 4G
technologies, it is still used in some parts of the world.
• Many people still find the 2G network more reliable than the more modern
networks

7. Third
Generation(3G) Technology
• Third Generation (3G) technology is an improved
version of wireless communication technology
which was released in the late 1990s. This
technology provided significant enhancements over
the 2G systems, such as increased data
transmission speeds and improved multimedia
capabilities. With the introduction of 3G technology,
the main focus is on data speeds, allowing users to
access the Internet, stream multimedia, and make
video calls.

8. Features of 3g Technology
•
• The main features of 3G technology are that it allows users to
access high-speed data services, such as streaming audio
and video and making video calls.
• It also offers improved coverage, allowing users to stay
connected in areas where 2G service may be poor.
• In addition, 3G technology allows for higher data transfer
speeds, making it ideal for accessing the Internet,
downloading large files, and streaming multimedia content.
• Finally, 3G technology is more energy efficient than 2G
systems, allowing for longer battery life.

9. Fourth Generation(4G)
Technology
•
Fourth Generation (4G) was designed to
provide higher data rates and increased
bandwidth to users. It is the successor to
3G and is a huge leap forward in terms of
speed and capability. 4G technology offers
much faster data speeds than 3G, providing
users with speeds up to 100 Mbps. This
means downloading a movie file will take
just seconds.

10. Features of 4g Technology
• 4G offers a much more reliable signal and connection when
compared to previous generations.
• Its improved signal strength and data transfer speeds allow
users to enjoy faster browsing and streaming experiences.
• Moreover, 4G technology allows for a better quality of voice
calls, as it uses a different type of voice codec to compress
audio signals.
• In addition, 4G networks are better equipped to handle data-
intensive activities like gaming, streaming videos, and sending
large documents. It also supports a variety of services,
including Location-Based services (LBS), Mobile TV, and VoIP.

11. Fifth Generation(5G) Technology
• 5G technology is the latest generation of
wireless technology and is currently being
rolled out. It is capable of handling data
transmissions of up to 10Gb/s, which is 100
times faster than 4G technology. This
technology will enable users to access the
internet more quickly, stream videos in
ultra-high definition, and access virtual and
augmented reality applications.

12. Features of 5G Technology:
Up to 10Gbps data rate - > 10
to 100x speed improvement
over 4G and 4.5G networks
1-millisecond latency
1000x bandwidth per unit
area
Up to 100x number of
connected devices per unit
area (compared with 4G LTE)
99.999% availability 100% coverage
90% reduction in network
energy usage
Up to 10-year battery life for
low-power IoT device

14. What makes 5G so fast:
According
According to communication
principles, the shorter the
frequency, the larger the
bandwidth.
Using
Using shorter
frequencies (millimeter waves
between 30GHz and 300GHz)
for 5G networks is why 5G can
be faster. This high-band 5G
spectrum provides the expected
boost in speed and capacity, low
latency, and quality.

15. What is 5G low latency
5G technology offers an
extremely low latency rate, the delay
between the sending and
receiving information. From 200
milliseconds for 4G, we go down to 1
millisecond(1 ms) with 5G.
Just think about it.
A millisecond is 1/1000 of a second.
The average reaction time for
humans to a visual stimulus is 250 ms
or 1/4 of a second. People are
capped at around 190-200 ms with
proper training.
Imagine now that your car
could react 250 times faster than
you.
Imagine it could also respond to
hundreds of incoming information
and communicate its reactions to
other vehicles and road signals within
milliseconds.
At 60 mph (100km/h), the reaction
distance is about 33 yards (30
meters) before you pull on the
brakes. With a 1ms reaction time, the
car would only have rolled more than
one inch (less than 3 centimeters).
