The idea of a mobile phone was considered a laughable matter and somewhat a utopia in the beginning of telephony. The portrayal of a utopia of mobile phone in literature dates back to the year 1931. It is found in Erich Kästner's children's book “The 35th of May”, or “Conrad's Ride to the South Seas”: A gentleman who rode along the sidewalk in front of them, suddenly stepped off the conveyor belt, pulled a phone from his coat pocket, spoke a number into it and shouted: "Gertrude, listen, I'll be an hour late for lunch because I want to go to the laboratory. Goodbye, sweetheart!" Then he put his pocket phone away again, stepped back on the conveyor belt, started reading a book... Who was to know back then that mobile phones would in the following years not only become a part of our everyday lives but also serve as mini computers allowing us to access the internet, conduct business, have teleconferences or simply communicate with those thousands of miles away.

It all started in 1908 when a Professor Albert Jahnke and the Oakland Transcontinental Aerial Telephone and Power Company claimed to have developed a wireless telephone. They were accused of fraud and the charge was then dropped, but they do not seem to have proceeded with production. In the 1940s, however, Mobile telephones for automobiles became available from some telephone companies but these early devices were bulky and consumed high power and the network supported only a few simultaneous conversations. The first fully automated mobile phone system for vehicles was launched in Sweden in 1956. Named MTA and it allowed calls to be made and received in the car using a rotary dial. The car phone could also be paged. Calls from the car were direct dial, whereas incoming calls required an operator to determine which base station the phone was currently at. On 3 April 1973 Martin Cooper, a Motorola researcher and executive, made the first mobile telephone call from handheld subscriber equipment, placing a call to Dr. Joel S. Engel of Bell Labs. The prototype handheld phone used by Dr. Cooper weighed 1.1 kg and measured 23 cm long, 13 cm deep and 4.45 cm wide. The prototype offered a talk time of just 30 minutes and took 10 hours to re-charge. The 1990s was when thing started to lead in the direction of smartphones with giant steps with the invention of 2G phones using digital instead of analog transmission and introducing the feature of SMS. These second generation phones brought about 3G phones and today our mobile phones have become mini computers.
