Southern Bell Telephone Company Building
The Southern Bell Telephone Company Building, now known as the AT&T Communications Building, is the main telephone exchange for Downtown Atlanta, downtown Atlanta, Georgia (U.S. state), Georgia. It is located at 51 Peachtree Center Avenue, on the northeast corner of Auburn Avenue. It was designed for Southern Bell by P. Thornton Marye, Marye, Alger and Vinour, in an austere art deco style. Originally planned to be 25 storey, stories in height, which would have made it the tallest building in Atlanta, it was completed in 1929 at six stories. Additions in 1947, 1948 and 1963 brought it to its present 14 stories.Sams, Gerald W. (ed), ''AIA Guide to the Architecture of Atlanta'', page 41. University of Georgia Press, 1993. The building is crowned by a microwave radio relay, microwave communications radio tower, tower.

Peachtree Center
Peachtree Center is a district located in Downtown Atlanta, Georgia. Most of the structures that make up the district were designed by Atlanta architect John C. Portman, Jr. A defining feature of the Peachtree Center is a network of enclosed pedestrian sky bridges suspended above the street-level, which have garnered criticism for discouraging pedestrian street life. The district is served by the Peachtree Center MARTA station, providing access to rapid transit. History Intended to be the new downtown for Atlanta, Peachtree Center emerged as a distinct district in the early 1970s as a networked realm of convention hotels, shopping galleries, and office buildings a quarter-mile north of Five Points. Peachtree Center is notable for its uniform embodiment of the modern architectural style popular at the time. Yet the defining feature of Peachtree Center is its insular orientation, which allows patrons and workers to avoid interacting with the street level by traversing the area th ...

Microwave Radio Relay
Microwave transmission is the transmission of information by electromagnetic waves with wavelengths in the microwave frequency range of 300MHz to 300GHz(1 m - 1 mm wavelength) of the electromagnetic spectrum. Microwave signals are normally limited to the line of sight, so long-distance transmission using these signals requires a series of repeaters forming a microwave relay network. It is possible to use microwave signals in over-the-horizon communications using tropospheric scatter, but such systems are expensive and generally used only in specialist roles. Although an experimental microwave telecommunication link across the English Channel was demonstrated in 1931, the development of radar in World War II provided the technology for practical exploitation of microwave communication. During the war, the British Army introduced the Wireless Set No. 10, which used microwave relays to multiplex eight telephone channels over long distances. A link across the English Channel allow ...

Telephone Exchange Buildings
A telephone is a telecommunications device that permits two or more users to conduct a conversation when they are too far apart to be easily heard directly. A telephone converts sound, typically and most efficiently the human voice, into electronic signals that are transmitted via cables and other communication channels to another telephone which reproduces the sound to the receiving user. The term is derived from el, τῆλε (''tēle'', ''far'') and φωνή (''phōnē'', ''voice''), together meaning ''distant voice''. A common short form of the term is ''phone'', which came into use early in the telephone's history. In 1876, Alexander Graham Bell was the first to be granted a United States patent for a device that produced clearly intelligible replication of the human voice at a second device. This instrument was further developed by many others, and became rapidly indispensable in business, government, and in households. The essential elements of a telephone are a micr ...

Art Deco Architecture In Georgia (U
Art is a diverse range of human activity, and resulting product, that involves creative or imaginative talent expressive of technical proficiency, beauty, emotional power, or conceptual ideas. There is no generally agreed definition of what constitutes art, and its interpretation has varied greatly throughout history and across cultures. In the Western tradition, the three classical branches of visual art are painting, sculpture, and architecture. Theatre, dance, and other performing arts, as well as literature, music, film and other media such as interactive media, are included in a broader definition of the arts. Until the 17th century, ''art'' referred to any skill or mastery and was not differentiated from crafts or sciences. In modern usage after the 17th century, where aesthetic considerations are paramount, the fine arts are separated and distinguished from acquired skills in general, such as the decorative or applied arts. The nature of art and related concepts, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
