Evolution of Cell Phones

Today we refer to our phones as cellphones or mobile phones. However, that was not the case when they first came about. The term “radiotelephony” was used to describe what we now call our cell phones. Early radiotelephony, “early” dating back to the 1940’s, services was available for a very small amount of people. The very first mobile phones were better known as radiotelephones and were first used in the early part of the last century. Radiotelephones were originally used for ship-to-shore or ship-to-ship communications.
“Inventor and entrepreneur Guglielmo Marconi, is credited with developing the first successful wireless telegraph.” Even though Marconi, is credited for developing the first successful wireless telegraph, it could only transmit the dots and dashes of Morse code. “In 1901, Marconi placed a radio aboard a steam-powered truck, in effect creating the first land based wireless mobile data network. “However, the first successful wireless transmission of human dialogue took place on Christmas Eve 1906.” Credit for this successful wireless transmission goes to Reginald Fessenden. He used a radio to transmit music and verbal communication to ships at sea in the Atlantic. When the 1920s rolled around mobile radio systems in the United States were operating at 2MHz.

In the 1990s, the phones had not only halved in size but weight as well. By 1994, the phones had once again halved their size when the Nokia 2100 was released. The Nokia 2100 was the first mobile phone to be mass marketed. It also weighed in at 200 grams or seven ounces.
Once the 2000s hit more changes started to happen to the world of mobile phones. During this time mobile phones and personal computers had crossed paths. For the first time phones had outsold computers worldwide. There were 450 million phones sold to only 120 million personal computers. After this happened another phone was introduced in the Spring of 2002. The Nokia 7650 was introduced and was a breakthrough product.
