Sweat Mountain
Sweat Mountain is a mountain in far northeastern Cobb County, Georgia, in the suburbs north of Atlanta. The exact GNIS location of its summit is , and it has an official (USGS) elevation of above mean sea level. It is the second-highest point in the county behind Kennesaw Mountain, and second in the core metro Atlanta area, behind Kennesaw Mountain, which is also in Cobb County. It is fifth if the exurban counties further north are considered. This height has made the mountain very attractive for radio, having several transmitters, radio towers, and antennas, for pagers, cellphones, broadcasting, and amateur radio. The fact that Stone Mountain and Kennesaw Mountain are both protected as parks has led to a proliferation of technology at the top. At the same time, both the antenna farm and the densely packed houses detract from the view of the mountain from surrounding areas of north east Cobb, south-southeast Cherokee (including much of Woodstock), and western Roswell.

Radio
Radio is the technology of communicating using radio waves. Radio waves are electromagnetic waves of frequency between 3 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves. They can be received by other antennas connected to a radio receiver; this is the fundamental principle of radio communication. In addition to communication, radio is used for radar, radio navigation, remote control, remote sensing, and other applications. In radio communication, used in radio and television broadcasting, cell phones, two-way radios, wireless networking, and satellite communication, among numerous other uses, radio waves are used to carry information across space from a transmitter to a receiver, by modulating the radio signal (impressing an information signal on the radio wave by varying some aspect of the wave) in the transmitter. In radar, used to locate and track ob ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
East Cobb
East Cobb is an unincorporated community in Cobb County, Georgia, United States, with a population of 164,055 people. History The area was developed as a suburb of Atlanta beginning in the 1960s. In contrast to other northern suburbs of Atlanta, East Cobb has remained unincorporated. Residents of East Cobb typically hold a Marietta address, although they are outside Marietta city boundaries. The idea of incorporating East Cobb as a city was suggested in 2009 by the organization "Citizens for the City of East Cobb". Yet the first serious discussion of incorporating East Cobb was initiated in 1998 by then Cobb County chairman Bill Byrne. Under Byrne's proposal, the city's boundary lines would be drawn by the Cobb Legislative Delegation, the county government would continue to provide water, sewer, police and fire services to the city for a nominal fee of one dollar per year, and the city would be governed by an elected mayor and five City Council members, with wards drawn by the ...

Antenna Farm
An antenna farm, satellite dish farm or dish farm is an area dedicated to television or radio telecommunications transmitting or receiving antenna equipment, such as C band (IEEE), C, Ku band, Ku or Ka band, Ka Band (radio), band satellite dish antennas, UHF/VHF/AM broadcasting, AM/FM broadcasting, FM transmitter towers or mobile cell towers. The history of the term "antenna farm" is uncertain, but it dates to at least the 1950s. In telecom circles, any area with more than three antennas could be referred to as an antenna farm. In the case of an AM broadcasting station (mediumwave and longwave, occasionally shortwave), the multiple mast radiators may all be part of an antenna system for a single station, while for VHF and UHF the site may be under joint venture, joint management. Alternatively, a single tower with many separate antennas is often called a "candelabra tower". Safety and security Commercial antenna farms are managed by radio stations, television stations, satel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Technology
Technology is the application of Conceptual model, conceptual knowledge to achieve practical goals, especially in a reproducible way. The word ''technology'' can also mean the products resulting from such efforts, including both tangible tools such as Kitchen utensil, utensils or machines, and intangible ones such as software. Technology plays a critical role in science, engineering, and everyday life. Technological advancements have led to significant changes in society. The earliest known technology is the stone tool, used during prehistory, followed by the control of fire—which in turn contributed to the Brain size, growth of the human brain and the development of language during the Pleistocene, Ice Age, according to the cooking hypothesis. The invention of the wheel in the Bronze Age allowed greater travel and the creation of more complex machines. More recent technological inventions, including the printing press, telephone, and the Internet, have lowered barriers to ...

Amateur Radio
Amateur radio, also known as ham radio, is the use of the radio frequency radio spectrum, spectrum for purposes of non-commercial exchange of messages, wireless experimentation, self-training, private recreation, radiosport, contesting, and emergency, emergency communications. The term ''"radio amateur"'' is used to specify ''"a duly authorized person interested in radioelectric practice with a purely personal aim and without wikt:pecuniary, pecuniary interest"'' (either direct monetary or other similar reward); and to differentiate it from commercial broadcasting, public safety (police and fire), or two-way radio professional services (maritime, aviation, taxis, etc.). The amateur radio service (''amateur service'' and ''amateur-satellite service'') is established by the International Telecommunication Union (ITU) through their recommended radio regulations. National governments regulate technical and operational characteristics of transmissions and issue individual station li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Broadcasting
Broadcasting is the data distribution, distribution of sound, audio audiovisual content to dispersed audiences via a electronic medium (communication), mass communications medium, typically one using the electromagnetic spectrum (radio waves), in a :wikt:one-to-many, one-to-many model. Broadcasting began with AM radio, which came into popular use around 1920 with the spread of vacuum tube radio transmitters and radio receiver, receivers. Before this, most implementations of electronic communication (early radio, telephone, and telegraph) were wikt:one-to-one, one-to-one, with the message intended for a single recipient. The term ''broadcasting'' evolved from its use as the agricultural method of sowing seeds in a field by casting them broadly about. It was later adopted for describing the widespread distribution of information by printed materials or by telegraph. Examples applying it to "one-to-many" radio transmissions of an individual station to multiple listeners appeared as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cellphone
A mobile phone or cell phone is a portable telephone that allows users to make and receive calls over a radio frequency link while moving within a designated telephone service area, unlike fixed-location phones ( landline phones). This radio frequency link connects to the switching systems of a mobile phone operator, providing access to the public switched telephone network (PSTN). Modern mobile telephony relies on a cellular network architecture, which is why mobile phones are often referred to as 'cell phones' in North America. Beyond traditional voice communication, digital mobile phones have evolved to support a wide range of additional services. These include text messaging, multimedia messaging, email, and internet access (via LTE, 5G NR or Wi-Fi), as well as short-range wireless technologies like Bluetooth, infrared, and ultra-wideband (UWB). Mobile phones also support a variety of multimedia capabilities, such as digital photography, video recording, and gami ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
