IBM PCradio
The PCradio was a notebook computer released by International Business Machines (IBM) in late 1991. Designed primarily for mobile workers such as service technicians, salespersons and public safety workers, the PCradio featured a ruggedized build with no internal hard disk drive and was optioned with either a cellular or ARDIS RF modem, in addition to a standard landline modem. Components The internals of the PCradio were encased in a slate-gray, hardened plastic case, which IBM said was resistant to heat, moisture, impact and certain chemicals. Its port doors, connectors, and keyboard were designed to be water-resistant through the use of gaskets, seals, and O-rings. It featured a monochrome LCD capable of rendering graphics in CGA mode and text at 80 columns by 25 lines. The laptop was powered by either a nickel–cadmium battery or a wall or car power adapter.

Handset
A handset is a component of a telephone that a user holds to the ear and mouth to receive audio through the receiver and speak to the remote party using the built-in transmitter. In earlier telephones, the transmitter was mounted directly on the telephone itself, which was attached to a wall at a convenient height or placed on a desk or table. Until the advent of the cordless telephone, the handset was usually wired to the base unit, typically by a flexible tinsel wire. The handset of a cordless telephone contains a radio transceiver which relays communication via a base station that is wired to the telephone line. A mobile phone does not require a base station and communicates directly with a cell site in designated frequency bands. Handset symbol A graphic symbol that designates a handset is used on cordless and mobile phones to specify placing or ending a telephone call. Usually a button with green upright (off-hook) handset icon is used for starting a call, and a red ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BellSouth
BellSouth, LLC (stylized as ''BELLSOUTH'' and formerly known as BellSouth Corporation) was 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.

Regional Bell Operating Companies
The Regional Bell Operating Companies (RBOC) are the result of '' United States v. AT&T'', the U.S. Department of Justice antitrust suit against the former American Telephone & Telegraph Company (later known as AT&T Corp.). On January 8, 1982, AT&T Corp. settled the suit and agreed to divest its local exchange service operating companies. Effective January 1, 1984, AT&T Corp.'s local operations were split into seven independent Regional Bell Operating Companies known as the Baby Bells. RBOCs were originally known as Regional Holding Companies (RHCs). Currently, three companies have the RBOCs as predecessors: AT&T, Verizon, and Lumen Technologies. Some other companies are holding onto smaller segments of the companies.

McCaw Cellular Communications
McCaw Cellular Communications was a cellular telephone pioneer in the United States. Savvy licensing of cellular spectrum in the early 1980s put McCaw Cellular in an extremely strong position, quickly outpacing the growth of the "Baby Bells" in the emerging market. The company purchased MCI Communications's mobile businesses in 1986, followed by LIN Broadcasting in 1989, giving them widespread access in all of the major US markets. Partnering with AT&T as a technology provider, McCaw introduced their "Cellular One" service in 1990, the first truly national cellular system. AT&T purchased 33% of the company in 1992, and arranged a merger in 1994 that made Craig McCaw one of AT&T's largest shareholders. In 2002, the company was spun off from AT&T to become AT&T Wireless Services. History McCaw Cellular Communications In 1966 J. Elroy McCaw sold one of his cable television holdings in Centralia, Washington to his three sons, including Craig who was 16 years old at the time. Craig t ...

Don Mills
Don Mills is a mixed-use neighbourhood in the North York district of Toronto, Ontario, Canada. It was developed to be a self-supporting "new town" and was at the time located outside Toronto proper.

Spango Valley
Spango Valley is a steep sided valley to the south-west of Greenock, Scotland. It runs approximately south west to north east for around from the confluence of the Spango Burn and Kip Water near Dunrod Farm, to Ravenscraig at the present day Aileymill Gardens.
