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), 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.
Mobile telephony is the provision of telephone services to mobile phones rather than fixed-location phones. Telephony is supposed to specifically point to a voice-only service or connection, though sometimes the line may blur.
1G refers to the first generation of cellular network (wireless) technology. These are mobile telecommunications standards that were introduced in the 1980s and were superseded by 2G. The main difference between these two mobile cellular generations is that the audio transmissions of 1G networks were analog, while 2G networks were entirely digital.
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 $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.
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 can make and receive calls over a radio frequency link while the user is moving within a telephone service area, as opposed to a fixed-location phone. The radio frequency link establishes a connection to the switching systems of a mobile phone operator, which provides access to the public switched telephone network (PSTN). Modern mobile telephone services use a cellular network architecture, and therefore mobile telephones are called cellphones in North America. In addition to telephony, digital mobile phones support a variety of other services, such as text messaging, multimedia messaging, email, Internet access, short-range wireless communications, satellite access, business applications, payments, multimedia playback and streaming, digital photography, and video games. Mobile phones offering only basic capabilities are known as feature phones ; mobile phones that offer greatly advanced computing capabilities are referred to as smartphones.
