Present-day telecommunications in Canada include telephone, radio, television, and internet usage. In the past, telecommunications included telegraphy available through Canadian Pacific and Canadian National.
The early history of radio is the history of technology that produces and uses radio instruments that use radio waves. Within the timeline of radio, many people contributed theory and inventions in what became radio. Radio development began as "wireless telegraphy". Later radio history increasingly involves matters of broadcasting.
Wireless telegraphy or radiotelegraphy is transmission of text messages by radio waves, analogous to electrical telegraphy using cables. Before about 1910, the term wireless telegraphy was also used for other experimental technologies for transmitting telegraph signals without wires. In radiotelegraphy, information is transmitted by pulses of radio waves of two different lengths called "dots" and "dashes", which spell out text messages, usually in Morse code. In a manual system, the sending operator taps on a switch called a telegraph key which turns the transmitter on and off, producing the pulses of radio waves. At the receiver the pulses are audible in the receiver's speaker as beeps, which are translated back to text by an operator who knows Morse code.
The Communications Act of 1934 is a United States federal law signed by President Franklin D. Roosevelt on June 19, 1934, and codified as Chapter 5 of Title 47 of the United States Code, 47 U.S.C. § 151 et seq. The act replaced the Federal Radio Commission with the Federal Communications Commission (FCC). It also transferred regulation of interstate telephone services from the Interstate Commerce Commission to the FCC.
Pirate radio or a pirate radio station is a radio station that broadcasts without a valid license.
Wireless communication is the transfer of information (telecommunication) between two or more points without the use of an electrical conductor, optical fiber or other continuous guided medium for the transfer. The most common wireless technologies use radio waves. With radio waves, intended distances can be short, such as a few meters for Bluetooth or as far as millions of kilometers for deep-space radio communications. It encompasses various types of fixed, mobile, and portable applications, including two-way radios, cellular telephones, personal digital assistants (PDAs), and wireless networking. Other examples of applications of radio wireless technology include GPS units, garage door openers, wireless computer mouse, keyboards and headsets, headphones, radio receivers, satellite television, broadcast television and cordless telephones. Somewhat less common methods of achieving wireless communications involve other electromagnetic phenomena, such as light and magnetic or electric fields, or the use of sound.
The British Broadcasting Company Limited (BBC) was a short-lived British commercial broadcasting company formed on 18 October 1922 by British and American electrical companies doing business in the United Kingdom. Licensed by the British General Post Office, its original office was located on the second floor of Magnet House, the GEC buildings in London and consisted of a room and a small antechamber.
The telecommunications policy of the United States is a framework of law directed by government and the regulatory commissions, most notably the Federal Communications Commission (FCC). Two landmark acts prevail today, the Communications Act of 1934 and the Telecommunications Act of 1996. The latter was intended to revise the first act and specifically to foster competition in the telecommunications industry.
The Office of Communications, commonly known as Ofcom, is the government-approved regulatory and competition authority for the broadcasting, telecommunications and postal industries of the United Kingdom.
The Marine, &c., Broadcasting (Offences) Act 1967, shortened to Marine Broadcasting Offences Act or "Marine Offences Act", became law in the United Kingdom at midnight on Monday 14 August 1967. It was subsequently amended by the Wireless Telegraphy Act 2006 and the Broadcasting Act 1990. Its purpose was to extend the powers of the Wireless Telegraphy Act 1949, beyond the territorial land area and territorial waters of the UK to cover airspace and external bodies of water.
The Commission for Communications Regulation (ComReg) is the general communications regulator for Ireland, covering almost all possible types of communications.
A UK Restricted Service Licence, is typically granted to radio stations and television stations broadcasting within the UK to serve a local community or a special event. Licences are granted by the broadcasting authority Ofcom.
Pirate radio in the United Kingdom has been a popular and enduring radio medium since the 1960s, despite expansions in licensed broadcasting, and the advent of both digital radio and internet radio. Although it peaked throughout the 1960s and again during the 1980s/1990s, it remains in existence today. Having moved from transmitting from ships in the sea to tower blocks across UK towns and cities, in 2009 the UK broadcasting regulator Ofcom estimated more than 150 pirate radio stations were still operating.
A wireless microphone, or cordless microphone, is a microphone without a physical cable connecting it directly to the sound recording or amplifying equipment with which it is associated. Also known as a radio microphone, it has a small, battery-powered radio transmitter in the microphone body, which transmits the audio signal from the microphone by radio waves to a nearby receiver unit, which recovers the audio. The other audio equipment is connected to the receiver unit by cable. In one type the transmitter is contained within the handheld microphone body. In another type the transmitter is contained within a separate unit called a "bodypack", usually clipped to the user's belt or concealed under their clothes. The bodypack is connected by wire to a "lavalier microphone" or "lav", a headset or earset microphone, or another wired microphone. Most bodypack designs also support a wired instrument connection. Wireless microphones are widely used in the entertainment industry, television broadcasting, and public speaking to allow public speakers, interviewers, performers, and entertainers to move about freely while using a microphone without requiring a cable attached to the microphone.
Broadcast law and Electricity law is the field of law that pertains to broadcasting. These laws and regulations pertain to radio stations and TV stations, and are also considered to include closely related services like cable TV and cable radio, as well as satellite TV and satellite radio. Likewise, it also extends to broadcast networks.
A video sender is a device for transmitting domestic audio and video signals wirelessly from one location to another. It is most commonly used for sending the output of a source device, such as a satellite television decoder, to a television in another part of a property and provides an alternative to cable installations.
The Wireless Telegraphy Act 2006 is an act of the Parliament of the United Kingdom. This act repealed the Wireless Telegraphy Act 1949.
The Broadcasting (Amendment) Act 2007 is an Act of the Oireachtas which was enacted in April 2007. It deals with Irish Analogue broadcasting systems and the amendment of legislation on Digital Terrestrial Television dating back to 2001. This act amends previous acts in particular the Broadcasting Act 2001.
