Examples of this type of communication include radio and traditional television programs such as the news.

Amplitude modulation ( AM ) is a technique used in electronic communication, most commonly for transmitting information via a radio carrier wave.

Beginning with Reginald Fessenden's audio demonstrations in 1906, it was also the original method used for audio radio transmissions, and remains in use today by many forms of communication —" AM " is often used to refer to the mediumwave broadcast band ( see AM radio ).

It may be the case that increased worldwide communication through radio, television, the Internet and globalization has reduced the tendency to regional variation.

To communicate to air traffic control that an aircraft is being hijacked, a pilot under duress should squawk 7500 or vocally, by radio communication, transmit "( Aircraft callsign ); Transponder seven five zero zero.

They also capture a boy named Jefri Olsndot, whom Steel intended on killing but eventually exploits in order to develop advanced technology ( such as cannon and radio communication ).

NATO pilots use the brevity code Fox One in radio communication to signal launch of a Semi-Active Radar Homing Missile such as the Sparrow.

small system of open-wire lines, microwave radio relay links, and a few radiotelephone communication stations ; mobile-cellular service is growing fast

* domestic: microwave radio relay, open wire, and radiotelephone communication stations

This also led to radio for communication between battalions.

They have no access to television, radio or the internet and are not allowed routine communication with the outside world.

This proved critical in early tank battles where German tank commanders exploited the organizational advantage over the Allies that radio communication gave them.

Each character in the alphabet is represented by a series of bits, sent over a communication channel such as a telegraph wire or a radio signal.

The first major model for communication was introduced by by Claude Shannon and Warren Weaver for Bell Laboratories in 1949 The original model was designed to mirror the functioning of radio and telephone technologies.

sparse system of microwave radio relay and HF radiotelephone communication stations

The civilian aircraft, which was out of radio communication, was intercepted approximately from the presidential retreat.

Code division multiple access ( CDMA ) is a channel access method used by various radio communication technologies.

Information and communication technologies ( ICTs ) are a “ diverse set of tools and resources used to communicate, create, disseminate, store, and manage information .” These technologies include computers, the Internet, broadcasting technologies ( radio and television ), and telephony.

During World War II and through the 1950s, high frequency (" short wave ") radio was widely used for military and diplomatic communication, and could be intercepted at great distances.

Domestic systems are open wire ; microwave radio relay ; radio communication in the HF, VHF, and UHF frequencies ; two domestic satellites provide the national trunk service.

The electromagnetic spectrum extends from below the low frequencies used for modern radio communication to gamma radiation at the short-wavelength ( high-frequency ) end, thereby covering wavelengths from thousands of kilometers down to a fraction of the size of an atom.

The island's historic role as a signal station continues today with its high-technology relay stations carrying vital TV, radio, telephone and military communication links between Shetland, Orkney and the Scottish mainland.

This is used by radio amateurs to transmit Morse code and is known as continuous wave ( CW ) operation.

In 1947, he claims to have become the first DJ to use twin turntables for continuous play, and in 1958 became a radio DJ at Radio Luxembourg.

Duddell didn't further develop his invention, but in 1902 Danish physicists Valdemar Poulsen and P. O. Pederson were able to increase the frequency produced into the radio range, inventing the Poulsen arc radio transmitter, the first continuous wave radio transmitter, which was used through the 1920s.

The DoD is required by law to " maintain a Standard Positioning Service ( as defined in the federal radio navigation plan and the standard positioning service signal specification ) that will be available on a continuous, worldwide basis ," and " develop measures to prevent hostile use of GPS and its augmentations without unduly disrupting or degrading civilian uses.

* The use of on-off keying to transmit Morse code at radio frequencies is known as continuous wave ( CW ) operation.

In the early 1920s George O. Squier was granted patents for a system for the transmission and distribution of signals over electrical lines which was the technical basis for what later became muzak, a technology streaming continuous music to commercial customers without the use of radio.

Wireless telegraphy is also known as " CW ", for continuous wave ( a carrier modulated by on-off keying ), as opposed to the earlier radio technique of using a spark gap.

Wireless telegraphy is still used widely today by amateur radio hobbyists where it is commonly referred to as radiotelegraphy, continuous wave, or just CW.

Examples of hard copy include teleprinter pages, continuous printed tapes, facsimile pages, computer printouts, and radio photo prints.

Thanks to coded messages transmitted over the BBC radio, each Maquis group was alerted of the impending D-Day by listening for seemingly meaningless messages such as " the crow will sing three times in the morning " or any other pre-arranged messages read in a continuous flow over the British airwaves.

Since July 15, 1929, the choir has performed a weekly radio broadcast called Music and the Spoken Word, which is one of the longest-running continuous radio network broadcasts in the world.

* WRPN-FM – a campus radio station with continuous broadcasts

This, along with continuous stage work, led to the attention of Australian Broadcasting Commission radio drama producer Lawrence H. Cecil, who was to act as his coach and mentor throughout 1939 and 1940.

Some modes of communication, such as continuous wave morse code transmissions ( especially by amateur radio operators ) and single sideband voice transmissions are more common in the HF range than on other frequencies, because of their bandwidth-conserving nature, but broadband modes, such as TV transmissions, are generally prohibited by HF's relatively small chunk of electromagnetic spectrum space.

It would not have relied upon continuous radio command signals from a ground location, or upon the ability to receive and react to such signals.

Over the next two years Sarnoff earned promotions to chief inspector and contracts manager for a company whose revenues swelled after Congress passed legislation mandating continuous staffing of commercial shipboard radio stations.

Demand assignment allows all users apparently continuous access of the radio spectrum by assigning carrier frequencies on a temporary basis using a statistical assignment process.

A year after the release of Tweekend, The Crystal Method released a continuous mix album based on their radio show, titled Community Service.

It also represents how far a radio wave has travelled per hop on the Earth's surface, for radio waves such as the short wave ( SW ) radio signals that employ continuous reflections for transmission.
