The Communications Research Centre Canada (CRC; French : Centre de recherches sur les communications Canada) is a Canadian government scientific laboratory for research and development in wireless technologies, with a particular focus on the efficient use of radio frequency spectrum. Its mission is as follows:
Officially established in 1969, the CRC's roots can be traced back to the late 1940s and the Canadian Defence Research Board (DRB). [1] The Defence Research Telecommunications Establishment (DRTE) existed from 1951 to 1969 within the DRB. In 1969, the federal government established a Department of Communications. The DRTE in its entirety was transferred to the new department's research branch, and renamed the Communications Research Centre. The CRC came under Industry Canada's wing in 1994. [2] Throughout its history, the CRC has made significant contributions to the information and communications technology sector in Canada and abroad. [3]
The CRC contributed to many "firsts" in Canadian communications, a number of which involved satellite communications. In 1962 the then-DRTE launched Alouette 1, Canada's first satellite. This led to the development of Canada's own communications satellite program. [4] In 1976 the HERMES satellite was launched. It was the first high-powered satellite and the first to operate at the higher frequency Ku-band. [5] In 1978, CRC offered the world's first direct-to-home satellite television broadcast via Hermes - a Stanley Cup hockey game. [6] Later that year, the CRC gave a public demonstration of Telidon, the Canadian videotex/teletext system that contributed to the development of international standards for the Web. [7] In 1983, CRC set up the first permanent Canadian governmental connection to the Internet, via an ARPANET connection (the first full international connection to the USENET portion of the then-Internet being the set up in 1981 by Henry Spencer at the University of Toronto). In the 1980s, the CRC funded and led the development of SHARP, which in 1987 became the world's first microwave-powered aircraft to fly. The CRC is responsible for many other firsts that have impacted Canadian telecommunications: in wireless systems; radio fundamentals, e.g., Software Defined Radio; [8] communication networks; photonics and interactive multimedia.
Recognition of the CRC's contributions include the 1993 designation of the Alouette-ISIS Program as one of the 10 most outstanding achievements in the first 100 years of engineering in Canada. [9] In 2007, the Alouette 1 Satellite Program was designated a National Historic Event. [10] In 1995, the Canadian Aeronautics and Space Institute awarded CRC's SARSAT team, headed by Dr. A. Winter, Mr. H. Werstiuk and Dr. B. Blevis, the first ever Alouette Award for contributions in advancing search and rescue technology. [11] The CRC has won three Emmy Awards: one in 1987 for its role in developing the Ku-band technology of the HERMES satellite; [12] another awarded in 2009 for its contribution to standardizing the ATSC Digital Television System; [13] and a third presented in 2012 for its role in standardizing loudness metering for use in broadcast audio. [14] CRC's research and development in telecommunications also earned it the 2007 Special Recognition Award from Canada's Telecommunication Hall of Fame. [15]
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.
A wireless network is a computer network that uses wireless data connections between network nodes. Wireless networking allows homes, telecommunications networks, and business installations to avoid the costly process of introducing cables into a building, or as a connection between various equipment locations. Admin telecommunications networks are generally implemented and administered using radio communication. This implementation takes place at the physical level (layer) of the OSI model network structure.
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.
The Anik satellites are a series of geostationary communications satellites launched for Telesat Canada for television, voice and data in Canada and other parts of the world, from 1972 through 2013. Some of the later satellites in the series remain operational in orbit, while others have been retired to a graveyard orbit. The naming of the satellite was determined by a national contest, and was won by Julie-Frances Czapla of Saint-Léonard, Québec. In Inuktitut, Anik means "brother".
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.

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).
