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.
A personal communications service (PCS) is set of communications capabilities that provide a combination of terminal mobility, personal mobility, and service profile management. This class of services comprises several types of wireless voice or wireless data communications systems, typically incorporating digital technology, providing services similar to advanced cellular mobile or paging services. In addition, PCS can also be used to provide other wireless communications services, including services that allow people to place and receive communications while away from their home or office, as well as wireless communications to homes, office buildings and other fixed locations. Described in more commercial terms, PCS is a generation of wireless cellular-phone technology, that combines a range of features and services surpassing those available in analogue- and first-generation (2G) digital-cellular phone systems, providing a user with an all-in-one wireless phone, paging, messaging, and data service.
In telecommunications and computer networks, a channel access method or multiple access method allows more than two terminals connected to the same transmission medium to transmit over it and to share its capacity. Examples of shared physical media are wireless networks, bus networks, ring networks and point-to-point links operating in half-duplex mode.
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.
Alouette 1 is a deactivated Canadian satellite that studied the ionosphere. Launched in 1962, it was Canada's first satellite, and the first satellite constructed by a country other than the Soviet Union or the United States. Canada was the fourth country to operate a satellite, as the British Ariel 1, constructed in the United States by NASA, preceded Alouette 1 by five months. The name "Alouette" came from the French for "skylark" and the French-Canadian folk song of the same name.
The National Telecommunications and Information Administration (NTIA) is an agency of the United States Department of Commerce that serves as the president's principal adviser on telecommunications policies pertaining to the United States' economic and technological advancement and to regulation of the telecommunications industry.
The Canadian Space Agency is the national space agency of Canada, established in 1990 by the Canadian Space Agency Act.
John Herbert Chapman was a Canadian space researcher. He started his career with his work on radio propagation and the ionosphere.
Resolute Bay is an Arctic waterway in the Qikiqtaaluk Region, Nunavut, Canada. It is located in Parry Channel on the southern side of Cornwallis Island. The hamlet of Resolute is located on the northern shore of the bay with Resolute Bay Airport to the northwest. The Inuit associated with Resolute Bay are called Qausuittuq and the population of the hamlet in the 2006 census was 229.
ISIS 1 and 2 were the third and fourth in a series of Canadian satellites launched to study the ionosphere over one complete solar cycle. After the success of Canada's Alouette 1, Canada and the United States jointly sent up three more satellites in the ISIS program. The first was named Alouette 2. As was the case for the Alouette satellites, RCA Ltd. of Montreal was the prime contractor for both ISIS 1 and 2.
The DRTE Computer was a transistorized computer built at the Defence Research Telecommunications Establishment (DRTE), part of the Canadian Defence Research Board. It was one of the earlier fully transistorized machines, running in prototype form in 1957, and fully developed form in 1960. Although the performance was quite good, equal to that of contemporary machines like the PDP-1, no commercial vendors ever took up the design, and the only potential sale to the Canadian Navy's Pacific Naval Laboratories, fell through. The machine is currently part of the Canadian national science and technology collection housed at the Canada Science and Technology Museum.
Spectrum management is the process of regulating the use of radio frequencies to promote efficient use and gain a net social benefit. The term radio spectrum typically refers to the full frequency range from 1 Hz to 3000 GHz that may be used for wireless communication. Increasing demand for services such as mobile telephones and many others has required changes in the philosophy of spectrum management. Demand for wireless broadband has soared due to technological innovation, such as 3G and 4G mobile services, and the rapid expansion of wireless internet services.
Colin Athol Franklin, CM, FRSC is an engineer and a leading pioneer in Canada's space programme. He played a leading role in the design, construction and application of Canada's first satellite, the Alouette. His extensive work and contribution to Canadian research and industrial development activities in space-related research and manufacturing, have been a significant influence in establishing Canada as a world leader in these fields.
The Prince Albert Radar Laboratory (PARL) was a radar research facility operated by the Defence Research Telecommunications Establishment (DRTE), part of the Canadian Defence Research Board. Its primary purpose was to test long-range radio propagation and radar techniques in the presence of the aurora borealis. This was part of a greater ABM effort being carried out in concert with the United States Air Force, and PARL operated along with two similar instruments at the Rome Air Development Centre and MIT Lincoln Laboratory. The site continues to operate today, used as a satellite downlink station known as the Prince Albert Satellite Station (PASS).
The Indian Telegraph Act, 1885 was the enabling legislation in India which governed the use of wired and wireless telegraphy, telephones, teletype, radio communications and digital data communications. It gives the Government of India exclusive jurisdiction and privileges for establishing, maintaining, operating, licensing and oversight of all forms of wired and wireless communications within Indian territory. It also authorizes government law enforcement agencies to monitor/intercept communications and tap phone lines under conditions defined within the Indian Constitution. The act came into force on 1 October 1885. Since that time, numerous amendments have been passed to update the act to respond to changes in technology.

Kenneth O. Hill is a Mexican Canadian physicist who specializes in the field of photonics. In the late 1970s, he discovered the phenomena of photosensitivity in optical fiber and has worked extensively in its applications. He first demonstrated Fiber Bragg gratings and their applications in optical communication and optical sensor systems. Further areas of his discovery and innovation include the phase mask technique for grating fabrication, fiber grating dispersion compensators, and wavelength selective fiber filters, multiplexers and demultiplexers. This field of research has led to the ability to create high speed fiber optic networks as well as many other communication applications that have revolutionized the telecommunications industry.
