ActiveSync is a synchronization program developed by Microsoft. It allows a mobile device to be synchronised with either a desktop PC, or a server running Microsoft Exchange Server or Kerio MailServer. Only Personal information manager (PIM) data (Email/Calendar/Contacts) may be synchronised with the Exchange Server. (Tasks may also be synchronised with Exchange Server on Windows Mobile 5.0 devices.) The PC synchronisation option, however, allows PIM synchronisation with Microsoft Outlook, along with Internet "favorites", files, and tasks, amongst other data types. Supported mobile devices include PDAs or Smartphones running Windows Mobile, or the Windows CE operating system, along with devices that don't use a Microsoft operating system[1], such as the Symbian platform. ActiveSync also provides for the manual transfer of files to a mobile device, along with limited backup/restore functionality, and the ability to install and uninstall mobile device applications.
Alternative software that allows mobile devices to synchronise non-Microsoft PIMs with a PC is also available; such as FinchSync[2] for Thunderbird, or Intellisync.
Starting with Windows Vista, the latest release of the Windows Operating System, ActiveSync has been replaced with the Windows Mobile Device Center.[3]
Address Book
Address Book also referred to as Phonebook is a book or a database used for storing entries called contacts. In cellphones each contact entry usually consists of a few standard fields (for example: Name, Mobile Number, Home Number, Work Number, E-mail address and Fax number). Most such systems store the details in alphabetical order of people's names, although in paper-based address books entries can easily end up out of order as the owner inserts details of more individuals or as people move.
AirTouch
AirTouch Communications was a U.S.-based wireless service provider that was created when PacTel Cellular was spun off from Pacific Telesis on April 1, 1994, forming both AirTouch Cellular and AirTouch Paging. On June 30, 1999, AirTouch Communications merged with UK-based Vodafone Group Plc, and the new company was called Vodafone AirTouch Plc. In September 1999, Vodafone AirTouch announced a $70-billion joint venture with Bell Atlantic Corp. to be called Verizon Wireless, and which would be comprised of the two companies' U.S. wireless assets: Bell Atlantic Mobile, AirTouch Cellular, PrimeCo Communications, and AirTouch Paging. This wireless joint venture received regulatory approval in six months, and began operations as Verizon Wireless on April 4, 2000. On June 30, 2000, the addition of GTE Wireless' assets, in connection with the merger of Bell Atlantic and GTE to form Verizon Communications, made Verizon Wireless the nation's largest wireless communications provider (until Cingular's acquisition of AT&T Wireless in 2004). For the joint venture, Verizon Communications owns 55% and UK-based Vodafone Group (formerly Vodafone AirTouch) owns 45%.

American Telephone & Telegraph
The American Telephone & Telegraph Company, in its later years simply AT&T Corporation, provided voice, video, data, and Internet telecommunications and professional services to businesses, consumers, and government agencies. During its long history, AT&T was at times the world's largest telephone company, the world's largest cable television operator, and a regulated monopoly.
At its peak, it employed one million people and its revenue was roughly $300 billion annually in today's dollars (for comparison, ExxonMobil's 2006 annual revenue was $377.6 billion).
Antenna
An antenna or aerial is a transducer designed to transmit or receive radio waves which are a class of electromagnetic waves. In other words, antennas convert radio frequency electrical currents into electromagnetic waves and vice versa.
Antennas are used in systems such as radio and television broadcasting, point-to-point radio communication, wireless lan, radar, and space exploration. Antennas usually work in air or outer space, but can also be operated under water or even through soil and rock at certain frequencies for short distances.
Physically, an antenna is an arrangement of conductors that generate a radiating electromagnetic field in response to an applied alternating voltage and the associated alternating electric current, or can be placed in an electromagnetic field so that the field will induce an alternating current in the antenna and a voltage between its terminals. Some antenna devices (parabola, horn antenna) just adapt the free space to another type of antenna.
Thomas Edison used antennas by 1885. Edison patented his system in U.S. Patent 465,971 . Antennas were also used in 1888 by Heinrich Hertz (1857-1894) to prove the existence of electromagnetic waves predicted by the theory of James Clerk Maxwell. Hertz placed the emitter dipole in the focal point of a parabolic reflector. He published his work and installation drawings in Annalen der Physik und Chemie (vol. 36, 1889).

AT&T Mobility
AT&T Mobility LLC (usually branded "AT&T",[4] and formerly named Cingular Wireless LLC) is the wholly owned wireless subsidiary of AT&T Inc.[5] AT&T Mobility is the largest mobile phone company in the United States and the second largest in Puerto Rico. [6] AT&T Mobility currently has 62 million subscribers as of 2007, and operates the largest digital voice and data network in the United States.[7]
Formerly a joint venture between SBC Communications and BellSouth, Cingular Wireless soon acquired the old AT&T Wireless; SBC later acquired the original AT&T and rebranded as "the new AT&T". Cingular became wholly-owned by the new AT&T in December 2006 as a result of AT&T's acquisition of BellSouth.
The division is currently in the process of being rebranded to match its new parentage. Renaming on a corporate level occurred immediately, and consumer branding will change to "AT&T," or a variant thereof, by the end of 2007. Until all regulatory filings are approved, however, and public awareness is fostered, the "Cingular" brand will continue to be used in store signage and media advertisements during a dual-branded transition, expected to last several months. This process began January 15, 2007.[8]
Among the services that AT&T aggressively promotes is its "Rollover" service, allowing customers to keep unused minutes from month to month on a twelve-month rolling cycle on its popular "Nation" nationwide plans.
AT&T Wireless Services
AT&T Wireless Services, Inc., formerly part of AT&T Corp., was a wireless telephone carrier in the United States, based in Redmond, Washington, and traded on the New York Stock Exchange under the stock symbol "AWE".
On October 26, 2004, AT&T Wireless completed a merger with Cingular Wireless to become the largest wireless carrier in the United States. Under the agreement, only the Cingular brand name would remain. On November 16, 2004, AT&T Wireless stores were rechristened under the Cingular banner. The legal entity AT&T Wireless Services, Inc. was renamed New Cingular Wireless Services, Inc. [1]
In late 2005, SBC (the majority partner in Cingular) acquired AT&T Corp., and renamed the combined company AT&T.
