The document discusses the evolution of communication from early humans shouting to convey messages to the development of modern communication technologies like the telephone and mobile phones. It traces the progression from early communication methods like signal fires and optical telegraphs to breakthroughs in wireless communication. The summary also notes that modern communication standards and growing adoption of mobile phones in India and globally has increased access to wireless communication technologies.

3.  Communication is the basis of our lives and we would in this day and age, be
handicapped without it. Everyday we are communicating with each other in
some way or another, be it by using words, actions or even expressions in
conveying a message. We humans depend not only on face-to-face
communication but the kind that brings technology to the fore to bridge that
gap between people by mere seconds across vast distances. We take a look
briefly into what are the major types of communication, along with their
importance.
 Communication as you can see, is an important factor that governs our
everyday lives. What is needed most is the effectiveness of how we
communicate, which is often misinterpreted. In order to pass a message
along in its entirety without jumbling up its core meaning, it is wise to always
review what is being sent, and think beforehand about what is right to say
when put into words. That is why, reviewing one's work diligently and
repeatedly is always stressed upon.

10. Beginning of the telephone era
• The need of communication
devices for armies in both
world wars gave birth to the
research of smaller and much
more efficient communication
devices
• Then around the early
1940’s came the
predeccesor to the modern
telephone - “ The WALKIE
TALKIE”
• In the early stages of the
radio,the idea of a mobile
telephone unit was considered
a joke.

11. Mobile telephoning
It wasn’t till after
the war, that the world
saw the first serious
solutions to mobile
telephoning.
In 1956 the world
first automatic mobile
telephoning system –
“ The ERICSSON MTA “
was introduced

12. • In 1981 the MMT system
was launched in
Scandinavia.
• It provided national
coverage in Sweden ,
Norway , Denmark and
Finland.
• But in those days the
telephones were bulky and
stow away items mostly
used in transport.

13. The pocket mobile phone
• It took more than a
decade for the mobile
phones to shrink in size
and weight under half a
kilo and then achieved
pocket success.
• The introduction of GSM
and other similar
standards saw the
emergence of even
smaller and lighter
phones.

14. Evolution of the video phones
Ever since the first telephone,
the idea of a video phone was
on most of the telecom
inventor’s mind.
Now it isn’t a dream
anymore. In 1999 ericsson
demonstrated the worlds first
MOBILE VIDEO CALL.
From 2001 3g systems
started to blaze new trail all
over the world

15. With the growing pace of communication and globalization, sources of
data communication have been growing in all the sectors. Now a days,
one of the fast growing spot in the stream of communication is the
Wireless and Mobile Technology. The Mobile Phone Companies
whether GSM or CDMA, are providing lucrative services at affordable
prices to the consumers.
The mobile phone companies are doing lot of research in
enhancing their services to attract new customers. According to one
news report, India is one of the World’s fastest growing mobile phone
markets. As per TRAI (Telecom Regulatory Authority of India) figures as
on April 6, 2011, there were 791.38 million mobile phone subscribers
in India. India is likely to become World's Number 1 Mobile Market by
2013 with more than a billion Mobile Users

16. The number of broadband connections in India has seen a continuous
growth since the beginning of 2006. As on Feb 2011, the total number
of broadband and Internet users in the country has reached 11.47
million, constituting 0.9% of the population.
Mobile and Wireless technology has become a fire wave of the
future to benefit every aspect of our life including business, personal,
education, medical, entertainment as well as global communication.
More than sixty percent of the world’s population has gone mobile
using stylish and excellent featured handsets, computers, laptops, net
books, palmtops, personal digital assistants, tablets, smart phones with
GPS devices and wireless terminals. These equipments are delivered
with WiFi, Bluetooth, 3G/4G services, virtual private networks and other
advanced communications technologies.
