Georgia is a state in the Southeastern United States. It began as a British colony in 1733, the last and southernmost of the original Thirteen Colonies to be established. Named after King George II of Great Britain, the Province of Georgia covered the area from South Carolina south to Spanish Florida and west to French Louisiana at the Mississippi River. Georgia was the fourth state to ratify the United States Constitution, on January 2, 1788. In 1802–1804, western Georgia was split to the Mississippi Territory, which later split to form Alabama with part of former West Florida in 1819. Georgia declared its secession from the Union on January 19, 1861, and was one of the original seven Confederate states. It was the last state to be restored to the Union, on July 15, 1870. Georgia is the 24th largest and the 8th most populous of the 50 United States. From 2007 to 2008, 14 of Georgia's counties ranked among the nation's 100 fastest-growing, second only to Texas. Georgia is known as the Peach State and the Empire State of the South. Atlanta, the state's capital and most populous city, has been named a global city. Atlanta's metropolitan area contains about 55% of the population of the entire state.
BellSouth, LLC is an American telecommunications holding company based in Atlanta, Georgia. BellSouth was one of the seven original Regional Bell Operating Companies after the U.S. Department of Justice forced the American Telephone & Telegraph Company to divest itself of its regional telephone companies on January 1, 1984.
BellSouth Mobility operated wireless networks using many different wireless communication standards. The most widely used of these technologies is called Digital AMPS, or D-AMPS. Data services were provided by BellSouth Wireless Data, and used the pre-2.5G Mobitex standard.
IS-54 and IS-136 are second-generation (2G) mobile phone systems, known as Digital AMPS (D-AMPS), and a further development of the North American 1G mobile system Advanced Mobile Phone System (AMPS). It was once prevalent throughout the Americas, particularly in the United States and Canada since the first commercial network was deployed in 1993. D-AMPS is considered end-of-life, and existing networks have mostly been replaced by GSM/GPRS or CDMA2000 technologies.
Mobitex is an OSI based open standard, national public access wireless packet-switched data network. Mobitex puts great emphasis on safety and reliability with its use by military, police, firefighters and ambulance services. It was developed in the beginning of the 1980s by the Swedish Televerket Radio. From 1988 the development took place in Eritel, a joint-venture between Ericsson and Televerket, later on as an Ericsson subsidiary. Mobitex became operational in Sweden in 1986.
BellSouth Mobility was a mobile phone network operated by the American landline telephone company BellSouth. It was founded in 1984 during the breakup of AT&T, which included dividing Advanced Mobile Phone Service, Inc. among the Baby Bells. It ran AMPS and D-AMPS across most of the territory covered by the BellSouth landline company. In 2000, it became part of the Cingular Wireless network, and the BellSouth branding was dropped; however, the company continued to exist as an operating subsidiary.
A mobile phone, cell phone, cellphone, or hand phone, sometimes shortened to simply mobile, cell or just 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. 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 cellular telephones or cell phones, in North America. In addition to telephony, 2000s-era mobile phones support a variety of other services, such as text messaging, MMS, email, Internet access, short-range wireless communications, business applications, video games, and digital photography. Mobile phones offering only those capabilities are known as feature phones; mobile phones which offer greatly advanced computing capabilities are referred to as smartphones.
The United States of America (USA), commonly known as the United States or America, is a country composed of 50 states, a federal district, five major self-governing territories, and various possessions. At 3.8 million square miles, the United States is the world's third or fourth largest country by total area and is slightly smaller than the entire continent of Europe's 3.9 million square miles. With a population of over 327 million people, the U.S. is the third most populous country. The capital is Washington, D.C., and the largest city by population is New York City. Forty-eight states and the capital's federal district are contiguous in North America between Canada and Mexico. The State of Alaska is in the northwest corner of North America, bordered by Canada to the east and across the Bering Strait from Russia to the west. The State of Hawaii is an archipelago in the mid-Pacific Ocean. The U.S. territories are scattered about the Pacific Ocean and the Caribbean Sea, stretching across nine official time zones. The extremely diverse geography, climate, and wildlife of the United States make it one of the world's 17 megadiverse countries.
Advanced Mobile Phone System (AMPS) was an analog mobile phone system standard developed by Bell Labs, and officially introduced in the Americas on October 13, 1983, 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 Pakistan by October 2004,, in Israel by January 2010, and Brazil by 2010.

Cellular Digital Packet Data (CDPD) was a wide-area mobile data service which used unused bandwidth normally used by AMPS mobile phones between 800 and 900 MHz to transfer data. Speeds up to 19.2 kbit/s were possible. The service was discontinued in conjunction with the retirement of the parent AMPS service; it has been functionally replaced by faster services such as 1xRTT, EV-DO, and UMTS/HSPA.
At the most basic level, Personal Communications Service (PCS) describes a set of communications capabilities which allows some combination of terminal mobility, personal mobility, and service profile management. More specifically, PCS refers to any of several types of wireless voice or wireless data communications systems, typically incorporating digital technology, providing services similar to advanced cellular mobile or paging services. In addition, PCS can also be used to provide other wireless communications services, including services which allow people to place and receive communications while away from their home or office, as well as wireless communications to homes, office buildings and other fixed havelocations. Described in more commercial terms, PCS is a generation of wireless-phone technology that combines a range of features and services surpassing those available in analog- and digital-cellular phone systems, providing a user with an all-in-one wireless phone, paging, messaging, and data service.
