Survival
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
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
Early 19th century the horse dominated Stage coaches and pony express The railroads changed this Then came electricity
Communication
TimelineFrom 1820 to 1880 discoveries in radio and electromagnetism
The Second Industrial RevolutionThe period 1870-1914 Innovations in the chemical, electric, petroleum and steel industries Adjacent Possible Growth period
Electromagnetism and Radio Foundation for electroniccommunications
New markets for communication
Telegraph Telephone Wireless Telegraph
Communication
The TelegraphFrom the Greek words tele = far and graphein = write (símriti)
Later to be called the “Victorian Internet”
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
The TelegraphSamuel F. B. Morse invented the first practical telegraph in 1837
Granted a patent 1838
Moore devised a telegraphic code consistingof dots and dashes
Shorter and longer electric impulse send down the wire - The Morse Code
Standardized messages
The TelephoneInvented 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
The TelephoneBell 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
The telephone was based on variable resistance (breytilegu viðnámi)
The Telephone
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
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 telephonesstarted to replace telegraphs
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
The Battle with Western UnionBell 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
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
Wireless Telegraph
Guglielmo Marconi saw an opportunityin wireless communication
Studied physics at the Universityof Bologna
Several experiments in 1894 inBologna, Italy
Marconi’s goal was to use hisknowledge developed in telephony
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
Skepticism and CompetitionMany 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
The Wireless Telegraph BubbleWireless 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
Government RegulationNo 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 CommunicationAround 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
Wireless Communication
Wireless communication started early 20th century
Wireless radio was important in WWII Many innovations such as spread spectrum and frequency hopping
Hedwig Eva Maria Kiesler 1913-2000
"Films have a certain place in a certain time period. Technology is
forever” - Hedy Lamarr
Wireless CommunicationAfter 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
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?

▪ The invention of the microchip played crucial role in the development of cell phones

GMS takes off in 1991 – unites Europe
Time Division Multiple Access – TDMA
2G Digital
US was slow in adopting 2G because roaming worked well
Digital did not add enough over analog
Texting and SIM cards was not known

GMS
Global System for Mobile Communication

Three times the capacity of analog, encryption, texting, SIM cards
GMS
TextingShort Message System allowed 160 letters
Became an accidental killer app – messages, chat, ring tones
First message sent 03.12.1992: “Merry Christmas”
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
