1940s
AT&T came up with the first radio-car- between phones that can be used only on highway between New York and Boston; they are known as push-to-talk phones. The system operates at frequencies of about 35 to 44 MHz, but once again there is a massive amount of interference in the system. AT&T declares the project a failure.
1970s
Motorola's Martin Cooper made the first call from a handheld mobile phone. To Joel S Engel his rival, at Bell Labs on April 3, 1973.
Bell Labs had imagined such technology since early 1940s and, at Cooper's own admission, he couldn't help but playfully rub the monumental in a bit. Cooper made the call during an interview with reporters from a New York street. He stood near a 900-Mhz base station on the 6th Avenue, between 53rd and 54th Streets, to place the call to Engel at Bell Lab. The call was made on a prototype of the DynaTAC (Dynamic Adaptive Total Coverage) 8000x, which, 10 years later, would become the first phone to be commercially released. In 1973. The phones wait was 1.1kg and measured 22.86 cm long, 12.7 cm deep, and 4.44cm wide. This phone offered 20 minutes of talk time and charged in 10 hours! These phone are huge compared to those of today. 1980s
The FCC makes firm rules about the growing cell phone industry in dealing with manufactures. It finally rules that Western Electric can manufacture products for both cellular and terminal use. (Basically they admit that they put the phone companies about 7 years behind). One of the most important years in cell phone evolution. The Cellular Technology Industry Association is created and helps to make the industry into an empire. One of its biggest contributions is when it helped create TDMA phone technology, the most evolved cell phone yet. It becomes available to the public in 1991.
1990s

At the end of the 1990s, cell phones were on their way to outnumbering landline phones in numerous countries, including Nigeria, India, El Salvador and the United Arab Emirates, which, by 2006, officially had more cell phones than landlines. Cell phones initially were two to three inches thick, had a large protruding antenna and a blocky body that spanned the length of the face. Over the course of the decade, cell phones gradually shrank in size, thickness and weight, and adopted digital panels with smaller keypads.

2000s
The Sanyo SCP-5300 removed the need to buy a Kodak, as it was the first cellular device to feature an integrated camera with a dedicated snapshot button. Unfortunately, it was limited to a 640x480 resolution, 4x digital zoom and 3-foot range. Regardless, users of the phone could snap photos on the go and then later upload them to their PC using a bundled software suite. 2004: First Ultra-Thin Phone Prior to the release of the Motorola Razr v3 in 2004, phones tended to be big and bulky. The Razr changed this with its its ridiculously thin, 14mm-thick frame of aircraft-grade aluminum. Other highlights included an internal antenna, a chemically-etched keypad and blue backlighting. It was, in essence, the first phone built to not only provide great functionality, but to also exude style and elegance.
2007: Apple iPhone When Apple entered the cellular industry in 2007, everything changed. Apple replaced the keyboard and keypad with a multi-touch touchscreen display that allowed customers to feel as if they were physically manipulating data with their fingers: clicking links, stretching/shrinking photos and flipping through albums. Plus, it brought the first ever fully-featured platform to cell phones. It was as if they took a computer operating system and squished it into a tiny phone. |

Today
There are many phones to choose from today. We can use smartphones for gaming, communicating, and web searching. Everyone will eventually need a phone. Smartphones keeps us entertained, and helps us communicate easier than righting a letter. We can receive messages faster than before! The evolution of smart isn't coming to an end because there are many more years to come!
