The first mobile phones were released by ATandamp;T in 1946, but due to the era’s restricted technological capabilities, they were only available in certain locations. There were only 11 or 12 channels available in a specific location, so if there were more users, the lines would become congested and you would have to wait to make or receive your call (via Britannica ).
The power requirements of these early mobile phones were similarly astounding, exceeding the capacity of any portable batteries at the time. Manufacturers installed them inside cars so they could rely on the relatively huge power supply provided by automobile batteries to meet these power requirements. They consequently acquired the common name “car phones.” By giving your phone a place to live near the dashboard, you were able to take your communication with you outside the house for the first time, but you remained chained. They made for incredibly huge mobile phones indeed, especially when you considered that the automobile, or at the very least the battery, was a vital component.
When phone makers learned they could increase user numbers by segmenting an area into units or cells, things started to change. Cell phones received their names from there. The major issue was that there were few available frequencies, at least until the FCC made a mostly underutilized portion of the UHF band available in 1968. Then, at last, everything began to come together, and the first cell phones emerged.
The world’s first text message was sent by Neil Papworth on December 3, 1992. He sent the message to Richard Jarvis, a Vodafone official, when he was still employed there as a coder. Little in the letter suggests that Papworth or Jarvis were aware of the significance of what they had accomplished or how it might affect international communication in the years to come. It said nothing more than “Merry Christmas.”
The message was delivered to Jarvis’ bulky Orbitel 901 phone, which weighs more than 4.5 pounds. In actuality, it hardly qualifies as a mobile phone at all, yet it was the first gadget to support function on a GSM network . Unfortunately, the Orbitel was unable to respond to the communication, and it was ignored (via NPR ).
Despite the unlucky start, that first message ended up being appropriate because text messaging quickly became a gift to us all, freeing us from having to answer phone calls. This was the first significant change in phone functionality that led to the modern gadgets we are familiar with, even though it was probably unpredictible at the time.
