The cellphone is one of the greatest inventions in this planet especially in terms of novelty. This gadget makes people’s daily lives easier. Its main function is to provide an easy way of communication through calls and text messages. Aside from this very important function, you can send e-mails, files, business cards, media files, applications, and messages to other cellphone users in less than a minute. If you can’t carry your laptop everyday or if you are in a hurry, just save your files into the memory of your cell phone and you can access them anywhere. Cell phones nowadays are very handy, portable, and have a friendly-user interface. A lot of games and apps like Pocket God Cheats can be downloaded. But did you know when were cellphones invented? They didn’t suddenly spring into existence. It took almost 70 years to launch the first cell phone.
The Evolution of Cellphones
The concept of the cellphone was derived from the telephone, which Alexander Graham Bell invented way back in 1876. It started the rise of modern communication tools that provide faster and more convenient ways to send messages aside from snail mails.
By the year 1900, another genius came to fame when he perfectly transmitted his voice to another radio tower via radio waves. That was the time that a wireless call was successfully done. The man behind this invention is Reginald Fessenden.
It was in the years of the 1940s to the 1970s when the hexagonal cell towers were built with the help of the engineers of Bell Lab, which is a part of AT&T that time. Because of these transmitters, wireless transmission of the human voice became possible between telephones on vehicles. The engineers transferred their ideas to more useful inventions. After putting the wireless telephones under the coverage of hexagonal cells, another man made a big impact in the cellphone’s evolution and that was Martin Cooper.
The First Mobile Phones
Cooper made the first handy mobile phone in 1973 and it was released in Japan under Motorola. It was called the DynaTAC Phone, which cost $3,995 and went in sale in the year 1983. It weighed 2.5kg and its size was 9 inches in height. This cellphone didn’t look like the modern cellphones today that are slim and very light. It was bulky and heavy. You have to charge it for 10 hours but you can only use it for 30 minutes (talking time).
After the launching of Motorola DynaTAC, another mobile phone company went into business. Nokia Communication was the company that made the transfers of data, like emails and multimedia, possible from a phone to another.
When cellphones were launched in the market, AT&T made the first cellular network and it was set up in Chicago in 1983. There were 2,000 supported subscribers of this network but the cellphones were still heavy and had only limited features.
Finally, more user friendly cellphones were out in the market in the latter part of the 1990s. They provided more features and had more battery life. They can send emails, text messages, multi-media messages, ring tones, and pictures aside from allowing you to make a call.
Today, there are many cellphone companies that are offering models of cellphones that are designed to replicate the way a human thinks. Some cellphones have sensors to imitate a person and some sensors are used to execute commands. Most cellphones now are all-in-one and they combine many functions of other gadgets. They do call and text and have tools like digital camera, Mp3 Player, video recorder, document reader, instant messenger, etc. As you can see, the cellphone has come a long way since 70 years ago.
