In 2011, there were 48 million
people in the world who have a
mobile phone but do not have
electricity at home

The History of Communication

16

Wars have been won on intelligence and the speed of
communications
Militaries and business community on the forefront on the
development of rapid communication
Communication

17

Early 19th century the horse dominated
Stage coaches and pony express
The railroads changed this
Then came electricity

18

Timeline
From 1820 to 1880 discoveries in radio and electromagnetism

Telephone

Communication

21

The Telegraph
From the Greek words

tele = far and 

graphein = write
(símriti)
Later to be called the
“Victorian Internet”

22

Simple device with battery and key for sending electric
signals
At the other end was a similar device emitting sound or
printing the signal
The Telegraph

23

The Telegraph
Samuel F. B. Morse invented the first practical
telegraph in 1837
Granted a patent 1838
Moore devised a telegraphic code consisting

of dots and dashes
Shorter and longer electric impulse send 

down the wire - The Morse Code
Standardized messages

24

The Telephone
Invented in 1876
At the time, the telegraph was dominant
Transferred sound waves with electric
current over wire
Alexander G. Bell
Created the first practical telephone
Based on experiments and improvements
in technology at the time

25

The Telephone
Bell was working on the harmonic telegraph
A device that could send more then one telegraph message at the
same time
Worked with skilled machinist named Thomas A. Watson
Joseph Henry encouraged him in 1875 to work on the telephone
instead of the harmonic telegraph

26

The telephone was based on variable resistance
(breytilegu viðnámi)
The Telephone

27

The Importance of Patents
Bell filed a notice for a patent Feb. 14, 1876
“The most valuable patent ever issued”
Elisha Gray also filed a patent that same day
The Patent Mystery
It is still a mystery what happened that day
Did Bell see Gray’s patent and update his?
Over 600 legal battles would challenge the
patent

28

Commercial Development
Bell had difficulty convincing contemporaries of the usefulness
of the telephone - the telegraph prevailed
Difficult to get investment
Bell offered the patent to Western Union
for $100.000 which they declined
Bell continued and slowly telephones

started to replace telegraphs

29

The Bell Company
In 1877 Bell and his backers formed the first Bell
Company
Business model:
Bell Company leased telephones and licensed
franchises instead of selling them

30

The Battle with Western Union
Bell sued Western Union for patent infringements and settled in 1879
Bell agreed not to go into the telegraph market, and Western Union agreed not to go
into the telephone market
Bell would buy Western Union’s telephone network with 50.000 subscribers in 50
cities and pay a license
Stock in Bell’s company rose from $50 to $500 in 1879

31

History
At the dawn of the 20th century, two mediums for communication were
dominant
The telegraph: Became important in the American Civil War (1861-65),
dominated by Western Union
The telephone: Dominant technology with the growth of Bell
Both these technologies had one problem: they were wire-based

32

Wireless Telegraph
Guglielmo Marconi saw an opportunity

in wireless communication
Studied physics at the University

of Bologna
Several experiments in 1894 in

Bologna, Italy
Marconi’s goal was to use his

knowledge developed in telephony

33

The Product
Marconi was improving the telegraph
“Spark Transmitter” where signals could represent the Morse code
Potential market:
Maritime market – British Royal Navy
Transatlantic communication

34

Skepticism and Competition
Many scientists were happy to point out flaws in Marconi’s inventions
Doubts that wireless had any application
Limitations – radios worded on fixed frequency
Security – anyone could listen in
The telegraph was initially 20 times faster
Cable companies showed no interest in wireless

35

The Wireless Telegraph Bubble
Wireless Telegraph was popular in the press
Many companies competed for stock funding
Resulted in Stock inflations - “The Wireless Telegraph bubble”
Sceptic voices started to respond
Series of articles in Success Magazine, 

“Fools and their money” 

appeared 1907


36

Government Regulation
No regulations controlled the airwaves
The sinking of RMS Titanic prompted governments to set
international standards of communication
The Marconi operator on the Titanic sent “C.Q.D”
C.Q. meant attention, D was for Distress
SOS is ... - - - ...

Wireless Communication
Around 1940 ideas for wireless communication were established
It was not until the development of microchips and technology for
building devices, that wireless communication became 

practical for individuals
Rules and cautiousness were to delay the progress
Also investments in land based systems

40

Wireless Communication
Wireless communication started early 20th century
Wireless radio was important in WWII
Many innovations such as spread spectrum and
frequency hopping

41

Hedwig Eva Maria Kiesler
1913-2000
"Films have a certain place in a
certain time period. Technology is
forever”
- Hedy Lamarr

42

Wireless Communication
After the war, use of wireless was 

restricted to certain profession
(police, military, taxis)
Not public solutions
The ideas for mobile radio networks
were developed in the 1940s
Area of radio cells – Cellular network

43

Wireless technology and the idea of
building a network of cells was
understood in 1940s. Why did the public
mobile phone not appear until in the late
1970s, early 80s?

Lessons Learned: Cellular Phones
▪ Cars became the first platform for phones

▪ First phones are analog

▪ Multiple standard – each country invents its own

– Problem with standards (history repeats itself?)

▪ Roaming problems in Europe call for a standard

▪ Digital standard developed in Europe, G2

▪ US does not have roaming problems and gets
stuck in G1
