History of Phones

A handheld portable phone was considered a gimmick, a "look what I got!" rich man's toy with dubious utility. Measuring 13 x 1.75 x 3.5 inches and weighing 28 ounces, the 8000X was so big and heavy, even its creators had nicknamed it "The Brick." Plus, you could only use it for a half an hour before the battery gave out. Who would pay a quarter of the average salary in 1984 — more than $9,000 in 2014 dollars — to carry around such a useless load, especially since payphones were everywhere and only cost a dime to use?

Smart PhonesA smartphone or smart phone is a mobile phone with an advanced mobile operating system which combines features of a personal computer operating system with other features useful for mobile or handheld use. They typically combine the features of a cell phone with those of other popular mobile devices, such as personal digital assistant (PDA), media player and GPS navigation unit. Most smartphones can access the Internet, have a touchscreen user interface, can run third-party apps, music players and are camera phones. Most Smartphones produced from 2012 onwards also have high-speed mobile broadband 4G LTE internet, motion sensors, and mobile payment mechanisms.

A patent for prepaid mobile phones (Top) was filed on November 16, 1994. Among the first, if not the first large metropolitan area implementation of prepaid mobile phone service in the United States was in the early 1990s at Houston Cellular Telephone Company, Houston, TX. HCTC was then an independent wireless carrier owned jointly by PacBell and BellSouth. HCTC introduced a service offering branded "calltrac" based on Voice Systems Technology, Inc.'s telephony platform with RPAC-2 billing during the first quarter of 1994.

Camera phones (bottom) camera phone is a mobile phone which is able to capture photographs. Most camera phones also record video. The first camera phone was sold in 1996 in Japan, a J-Phone model, about a decade after the first digital camera was sold in Japan in December 1989.[1]Most camera phones are simpler than separate digital cameras. Their usual fixed-focus lenses and smaller sensors limit their performance in poor lighting. Lacking a physical shutter, some have a long shutter lag. Photoflash, if featured, is typically provided by an LED source which illuminates less intensely over a much longer exposure time than a bright and near-instantaneous flash strobe.
