Advanced Mobile Phone System (AMPS) was an analog mobile phone system standard originally developed by Bell Labs and later modified in a cooperative effort between Bell Labs and Motorola. It was officially introduced in the Americas on October 13, 1983, and was deployed in many other countries too, including Israel in 1986, Australia in 1987, Singapore in 1988, and Pakistan in 1990. It was the primary analog mobile phone system in North America through the 1980s and into the 2000s. As of February 18, 2008, carriers in the United States were no longer required to support AMPS and companies such as AT&T and Verizon Communications have discontinued this service permanently. AMPS was discontinued in Australia in September 2000, in India by October 2004, in Israel by January 2010, and Brazil by 2010.
Motorola, Inc. was an American multinational telecommunications company based in Schaumburg, Illinois. It was founded in 1928 as Galvin Manufacturing Corporation by brothers Paul and Joseph Galvin. The company changed its name to Motorola in 1947. After having lost $4.3 billion from 2007 to 2009, Motorola was split into two independent public companies, Motorola Mobility and Motorola Solutions, on January 4, 2011. The reorganization was structured with Motorola Solutions legally succeeding Motorola, Inc., and Motorola Mobility being spun off.
Wireless communication is the transfer of information (telecommunication) between two or more points without the use of an electrical conductor, optical fiber or other continuous guided medium for the transfer. The most common wireless technologies use radio waves. With radio waves, intended distances can be short, such as a few meters for Bluetooth, or as far as millions of kilometers for deep-space radio communications. It encompasses various types of fixed, mobile, and portable applications, including two-way radios, cellular telephones, personal digital assistants (PDAs), and wireless networking. Other examples of applications of radio wireless technology include GPS units, garage door openers, wireless computer mouse, keyboards and headsets, headphones, radio receivers, satellite television, broadcast television and cordless telephones. Somewhat less common methods of achieving wireless communications involve other electromagnetic phenomena, such as light and magnetic or electric fields, or the use of sound.
A walkie-talkie, more formally known as a handheld transceiver, HT, or handheld radio, is a hand-held, portable, two-way radio transceiver. Its development during the Second World War has been variously credited to Donald Hings, radio engineer Alfred J. Gross, Henryk Magnuski and engineering teams at Motorola. First used for infantry, similar designs were created for field artillery and tank units, and after the war, walkie-talkies spread to public safety and eventually commercial and jobsite work.
A car phone is a mobile radio telephone specifically designed for and fitted into an automobile. This service originated with the Bell System and was first used in St. Louis, Missouri, on June 17, 1946.
1G refers to the first generation of mobile telecommunications standards, introduced in the 1980s. This generation was characterized by the use of analog audio transmissions, a major distinction from the subsequent 2G networks, which were fully digital. The term "1G" itself was not used at the time, but has since been retroactively applied to describe the early era of cellular networks.
The history of mobile phones covers mobile communication devices that connect wirelessly to the public switched telephone network.
The DynaTAC is a series of cellular telephones manufactured by Motorola from 1983 to 1994. The Motorola DynaTAC 8000X received approval from the U.S. FCC on September 21, 1983. A full charge took roughly 10 hours, and it offered 30 minutes of talk time. It also offered an LED display for dialing or recall of one of 30 phone numbers. It was priced at US$3,995 in 1984, its commercial release year, equivalent to $11,716 in 2023. DynaTAC was an abbreviation of "Dynamic Adaptive Total Area Coverage".
The Motorola International 3200 was the first digital hand-held mobile telephone introduced in 1992, along with the more compact 5200, 5080, 7200 and 7500 "flip phones" introduced in 1994. It was preceded by the International 1000 and 2000 GSM phones, quite big, and although being the first GSM portable phones, they were not GSM certified, therefore couldn't be officially connected to the network.
A mobile phone operator, wireless provider, or carrier is a mobile telecommunications company that provides wireless Internet GSM services for mobile device users. The operator gives a SIM card to the customer who inserts it into the mobile device to gain access to the service.
The history of communication technologies have evolved in tandem with shifts in political and economic systems, and by extension, systems of power. Communication can range from very subtle processes of exchange to full conversations and mass communication. The history of communication itself can be traced back since the origin of speech circa 100,000 BCE. The use of technology in communication may be considered since the first use of symbols about 30,000 years BCE. Among the symbols used, there are cave paintings, petroglyphs, pictograms and ideograms. Writing was a major innovation, as well as printing technology and, more recently, telecommunications and the Internet.
Douglas H. Ring was one of the Bell Labs engineers that invented the cell phone. The history of cellular phone technology began on December 11, 1947 with an internal memo written by Douglas H. Ring in which he proposed development of a cellular telephone system by AT&T.
The Motorola bag phone is the colloquial name for a line of personal transportable cellular telephones manufactured by Motorola, inc. from 1988 to 2000.
A mobile phone, or cell phone, is a portable telephone that allows users to make and receive calls over a radio frequency link while moving within a designated telephone service area, unlike fixed-location phones. This radio frequency link connects to the switching systems of a mobile phone operator, providing access to the public switched telephone network (PSTN). Modern mobile telephony relies on a cellular network architecture, which is why mobile phones are often referred to as 'cell phones' in North America.
Mobile interaction is the study of interaction between mobile users and computers. Mobile interaction is an aspect of human–computer interaction that emerged when computers became small enough to enable mobile usage, around the 1990s.
Richard H. Frenkiel is an American engineer, known for his significant role in the early development of cellular telephone networks.
Arlene Joy Harris is an entrepreneur, inventor, investor, and policy advocate in the telecommunications industry. She is the president and co-founder of Dyna LLC, an incubator for start-up and early-stage organizations historically in the wireless technology field. Harris is widely recognized as a pioneer in mobile and wireless enterprise and an innovator of consumer products and services. In May 2007, she became the first female inductee of the Wireless Hall of Fame, and was named to the Consumer Technology Hall of Fame in 2017.
