The mobile phone has changed the way people communicate with one another. It has become a necessity rather than a luxury, as it is now with us everywhere. People keep their mobile phones with them at all times. It is their constant companion. The history of the mobile phone dates back to the early 1900s. Before the mobile phone became ubiquitous, there were radio telephones and CB radios. The radio telephones were used for voice communication and the CB radios were used for short-range radio communications. However, these were not mobile. They required wires and were stationary. The first mobile phone was invented by a German electronics engineer named Heinrich Pfund in 1876.
What is a Mobile Phone?
A mobile phone is any device that makes and receives calls and text messages from mobile phone networks. It is portable and you can take it anywhere. It doesn’t require a landline phone for communication and you can use it anywhere. If you need to call someone who does not have a mobile phone, you can use a landline and make the call from the person’s house. However, this is becoming less common as more and more people get mobile phones.
Today, people have different reasons for getting a mobile phone. Some use it for calling and messaging others. Some use it for making calls to emergency services and others use it for GPS navigation and maps.
The First Mobile Phone
The first mobile phone was invented in 1876 by a German electronics engineer named Heinrich Pfund. It was used for wireless communication and it used electromagnetic waves to transmit and receive signals. The first mobile phone was made of wood and had a dial that moved a contact in order to complete a circuit. It was used only by the military and it could only transmit. This phone was able to transmit Morse code by connecting with a telegraph.
It was a hand-cranked device that used two wires. It was also different from modern mobile phones in that it had no network capabilities.
Development of the Mobile Phone
The development of the mobile phone started out with the idea of making a telephone that could be used anywhere. After some time, people realized that the phone could also be used for other purposes like making calls, sending text messages, etc. The first major development in the mobile phone was the invention of the mobile phone with a keypad. This made the mobile phone more user-friendly.
The Second Generation of the Mobile Phone
The second generation of the mobile phone was introduced in the early 1990s. It was called the “2G network” as it was a second-generation (2G) cellular network. The 2G network mainly used analog signals to transmit data and voice. The second generation of the mobile phone also made the handsets smaller and lighter so that they could be easily carried around.
The Third Generation of the Mobile Phone
These phones had a better range and could also facilitate text messaging. The third generation of mobile phones was mainly used for making voice calls.
These third generation mobile phones had a keypad with a small LCD screen below. One could easily make calls and send/receive messages by dialing numbers with these phones. The third generation of the mobile phone was introduced in the year 2000. It was called 3G. The 3G mobile networks used digital signals to transmit data and voice. In addition to this, 3G networks also introduced “W-CDMA” as a third generation. W-CDMA is a digital and spread spectrum method of transmitting data.
Evolution of the Mobile Phone
Soon after the third generation of the mobile phone was introduced, there was a demand from the telcos and the users for a “4G” network. The 4G networks used “LTE” which is a “Long-Term-Evolution” technology. LTE stands for “LTE-Advanced” as well. These technologies have made the mobile phone network more reliable and stable.
Current-Day Mobile Phones
Currently, the most popular mobile phone network in the world is “4G”. This is “4G LTE” and it uses “LTE-Advanced” technologies. The current-day mobile phone networks and devices use the “W-CDMA” and “LTE” technologies. In the year 2002, the first smartphone was launched. These phones were more sophisticated and featured internet connection, games, and music. However, these phones were not accessible at all times since they required constant Internet connectivity.
By 2007, Apple launched the first iPhone. This phone was accessible at all times and did not need any connectivity to work. The iPhone was revolutionary as it changed the way people communicate.
