Rogers Wireless
Rogers Wireless Inc. is a Canadian wireless telephone company headquartered in Toronto, providing service nationally throughout Canada. It is a wholly owned subsidiary of Rogers Communications. The company had revenues of just under $15.1 billion in 2018. Rogers Wireless is the largest wireless carrier in Canada, with 10.8 million subscribers as of Q3 2020. The company was originally started by David Margolese as an expansion of his pager firm, Canadian Telecom, formed in 1978. With the 1983 introduction of AMPS, the first North American standard for cell phones, Margolese started plans to expand the company into this new market. This required large amounts of capital. A group of private investors consisting of Margolese, Ted Rogers, Marc Belzberg and Philippe de Gaspé Beaubien formed the newly renamed Cantel in 1984 and opening for service in July 1985. Rogers purchased a controlling interest in the company in 1986, and bought out all of the shares of the other members by 1 ...

Subsidiary
A subsidiary, subsidiary company or daughter company is a company owned or controlled by another company, which is called the parent company or holding company. Two or more subsidiaries that either belong to the same parent company or having a same management being substantially controlled by same entity/group are called sister companies. The subsidiary can be a company (usually with limited liability) and may be a government- or state-owned enterprise. They are a common feature of modern business life, and most multinational corporations organize their operations in this way. Examples of holding companies are Berkshire Hathaway, Jefferies Financial Group, The Walt Disney Company, Warner Bros. Discovery, or Citigroup; as well as more focused companies such as IBM, Xerox, and Microsoft. These, and others, organize their businesses into national and functional subsidiaries, often with multiple levels of subsidiaries. Details Subsidiaries are separate, distinct legal entit ...

Mobile Network Operator
A mobile network operator (MNO), also known as a wireless service provider, wireless carrier, cellular company, or mobile network carrier, is a provider of wireless communications services that owns or controls all the elements necessary to sell and deliver services to an end user, including radio spectrum allocation, wireless network infrastructure, back haul infrastructure, billing, customer care, provisioning computer systems, and marketing and repair organizations. Operator In addition to obtaining revenue by offering retail services under its own brand, an MNO may also sell access to network services at wholesale rates to mobile virtual network operators (MVNO). A key defining characteristic of a mobile network operator is that an MNO must own or control access to a radio spectrum license from a regulatory or government entity. A second key defining characteristic of an MNO is that it must own or control the elements of the network infrastructure necessary to provide ...

Code-division Multiple Access
Code-division multiple access (CDMA) is a channel access method used by various radio communication technologies. CDMA is an example of multiple access, where several transmitters can send information simultaneously over a single communication channel. This allows several users to share a band of frequencies (see bandwidth). To permit this without undue interference between the users, CDMA employs spread spectrum technology and a special coding scheme (where each transmitter is assigned a code). CDMA optimizes the use of available bandwidth as it transmits over the entire frequency range and does not limit the user's frequency range. It is used as the access method in many mobile phone standards. IS-95, also called "cdmaOne", and its 3G evolution CDMA2000, are often simply referred to as "CDMA", but UMTS, the 3G standard used by GSM carriers, also uses "wideband CDMA", or W-CDMA, as well as TD-CDMA and TD-SCDMA, as its radio technologies. It can be also used as a cha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fido Solutions
Fido is a Canadian mobile network operator owned by Rogers Communications. Since its acquisition by Rogers in 2004, it has operated as a Mobile virtual network operator (MVNO) using the Rogers Wireless network. Fido's logo is a yellow doghouse. The name, "Fido," was suggested to Microcell Solutions, the first importer of GSM technology from Europe to Canada, on the recommendation of its marketing-communications agency at the time, BOS (Beauchesne, Ostiguy, Simard) of Montreal (now DentsuBos). The agency had been searching for a name that would appeal to both French- and English-speaking consumers. The brand name "Fido" inevitably led to the use of dogs in its commercials, which became the brand's informal trademark in TV advertising, starting in 1995. During the 2000s it ran ads where the narrator finished by catching a jumping dog and saying "regrettably, only from Fido". As of 2017, the tagline is "Go get it." Fido pioneered the concept of providing unlimited service in selec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

AT&T
AT&T Inc. is an American multinational telecommunications holding company headquartered at Whitacre Tower in Downtown Dallas, Texas. It is the world's largest telecommunications company by revenue and the third largest provider of mobile telephone services in the U.S. , AT&T was ranked 13th on the ''Fortune'' 500 rankings of the largest United States corporations, with revenues of $168.8 billion. During most of the 20th century, AT&T had a monopoly on phone service in the United States. The company began its history as the American District Telegraph Company, formed in St. Louis in 1878. After expanding services to Arkansas, Kansas, Oklahoma and Texas, through a series of mergers, it became Southwestern Bell Telephone Company in 1920, which was then a subsidiary of American Telephone and Telegraph Company.

Long-distance Calling
In telecommunications, a long-distance call (U.S.) or trunk call (also known as a toll call in the U.K. ) is a telephone call made to a location outside a defined local calling area. Long-distance calls are typically charged a higher billing rate than local calls. The term is not necessarily synonymous with placing calls to another telephone area code. Long-distance calls are classified into two categories: national or domestic calls which connect two points within the same country, and international calls which connect two points in different countries. Within the United States there is a further division into long-distance calls within a single state (intrastate) and interstate calls, which are subject to different regulations (counter-intuitively, calls within states are usually more expensive than interstate calls). Not all interstate calls are long-distance calls. Since 1984 there has also been a distinction between intra-local access and transport area (LATA) calls and those ...

Microwave Relay
Microwave transmission is the transmission of information by electromagnetic waves with wavelengths in the microwave frequency range of 300MHz to 300GHz(1 m - 1 mm wavelength) of the electromagnetic spectrum. Microwave signals are normally limited to the line of sight, so long-distance transmission using these signals requires a series of repeaters forming a microwave relay network. It is possible to use microwave signals in over-the-horizon communications using tropospheric scatter, but such systems are expensive and generally used only in specialist roles. Although an experimental microwave telecommunication link across the English Channel was demonstrated in 1931, the development of radar in World War II provided the technology for practical exploitation of microwave communication. During the war, the British Army introduced the Wireless Set No. 10, which used microwave relays to multiplex eight telephone channels over long distances. A link across the English Channel all ...

CNCP Telecommunications
CNCP Telecommunications (Canadian National-Canadian Pacific Telecommunications) was an electrical telegraph operator and later a telecom company, which operated between 1967 and 1990. CNCP was created as a joint venture between the Canadian National Railway and the Canadian Pacific Railway in the era when telegraph operation was declining and maintaining two separate networks was no longer profitable. The new company also began several expansions into new markets, first with a Montreal to Vancouver microwave relay network carrying voice and data, and later, its replacement with fibre optic links. Rogers Communications purchased a major stake in the company in 1984, and CN sold its remaining share in 1988. The network was taken over entirely by Rogers in 1990, and renamed it Unitel Communications in a bid to enter the commercial long distance market. This division changed hands several times from 2002 to 2012 when it was renamed Allstream. History Beginnings Beginning in 196 ...

Advanced Mobile Phone System
Advanced Mobile Phone System (AMPS) was an analog mobile phone system standard originally developed by Bell Labs and later modified in a cooperative effort between Bell Labs and Motorola. It was officially introduced in the Americas on October 13, 1983,Private Line and was deployed in many other countries too, including Israel in 1986, Australia in 1987, Singapore in 1988, and Pakistan in 1990. It was the primary analog mobile phone system in North America (and other locales) through the 1980s and into the 2000s. As of February 18, 2008, carriers in the United States were no longer required to support AMPS and companies s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pager
A pager (also known as a beeper or bleeper) is a wireless telecommunications device that receives and displays alphanumeric or voice messages. One-way pagers can only receive messages, while response pagers and two-way pagers can also acknowledge, reply to and originate messages using an internal transmitter. Pagers operate as part of a paging system which includes one or more fixed transmitters (or in the case of response pagers and two-way pagers, one or more base stations), as well as a number of pagers carried by mobile users. These systems can range from a restaurant system with a single low power transmitter, to a nationwide system with thousands of high-power base stations. Pagers were developed in the 1950s and 1960s, and became widely used by the 1980s. In the 21st century, the widespread availability of cellphones and smartphones has greatly diminished the pager industry. Nevertheless, pagers continue to be used by some emergency services and public safety personn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Canadian Mobile Phone Companies
As of March 2021, there are over 33 million wireless subscriptions in Canada. Approximately 90% of Canadian mobile phone users subscribe to one of the four largest national telecommunication companies (Rogers Wireless, Bell Mobility, Freedom Mobile and Telus Mobility) or one of their subsidiary brands. These four mobile network operators own and operate transmission facilities that cover most of the country, though they sometimes share each other's networks in certain geographical regions in order to reduce costs and reach more customers. The remaining 10% of subscribers are served by smaller, regional providers, mobile virtual network operators (MVNOs), and resellers. Regional providers own and operate transmission facilities that cover a limited area and rely on partnerships with national service providers to connect their customers across Canada. In contrast, MVNOs and resellers do not own spectrum or network infrastructure and are required to lease network capacity from other ...
