Tinshill BT Tower
The Tinshill BT Tower (also known locally as Cookridge Tower, or Tinshall BT Radio Station) is a 60.96 metres ( 200 ft) tall telecommunication tower located on the east side of Otley Old Road in the north of Leeds, West Yorkshire, England. It is in an elevated part of Leeds, with its base 192 metres above sea level. It is one of fourteen BT towers built of reinforced concrete. The tower is 53 metres tall and consists of a steel lattice tower on top of a concrete base. It was built in 1951 as part of chain of stations relaying television between Telephone House in Manchester and Kirk O'Shotts in Scotland, part of the British Telecom microwave network. In 2002 it had 16 large microwave dishes providing point-to-point communications, and roughly 50 other small microwave dishes, mobile phone, paging and TETRA transmitters. The BT dishes were 3 and 3.7 metres diameter and mostly transmitted on 11 GHz. In 2002, prompted by a request from the local MP, Harold Best, it was the ...

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 personne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buildings And Structures In Leeds
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artistic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Towers
Several extant building fulfill the engineering definition of a tower: "a tall human structure, always taller than it is wide, for public or regular operational access by humans, but not for living in or office work, and are ''self-supporting'' or ''free-standing'', which means no guy-wires for support." This definition excludes continuously habitable buildings and skyscrapers as well as radio and TV masts. Also excluded because they are not designed for public or regular operational access are bridge towers or pylons, wind turbines, chimneys, transmission towers, sculptures and most large statues and obelisks. Towers are most often built to use their height for various purposes, and can stand alone or as part of a larger structure. Some common purposes are for telecommunications, and as a viewing platform. The Tokyo Skytree, completed in February 2012, is , making it the tallest tower, and third-tallest free-standing structure in the world. Entirely self-supported towers ...

Radio Masts And Towers
Radio masts and towers are typically tall structures designed to support antennas for telecommunications and broadcasting, including television. There are two main types: guyed and self-supporting structures. They are among the tallest human-made structures. Masts are often named after the broadcasting organizations that originally built them or currently use them. In the case of a mast radiator or radiating tower, the whole mast or tower is itself the transmitting antenna. Terminology The terms "mast" and "tower" are often used interchangeably. However, in structural engineering terms, a tower is a self-supporting or cantilevered structure, while a mast is held up by stays or guys. Broadcast engineers in the UK use the same terminology. A mast is a ground-based or rooftop structure that supports antennas at a height where they can satisfactorily send or receive radio waves. Typical masts are of steel lattice or tubular steel construction. Masts themselves play no part in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Health Protection Agency
The Health Protection Agency (HPA) was a non-departmental public body in the United Kingdom. It was an organisation that was set up by the UK government in 2003 to protect the public from threats to their health from infectious diseases and environmental hazards. The HPA's role was to provide an integrated approach to protecting public health in the UK. It did this by providing advice and information to the general public, health professionals, and local government and by providing emergency services, support and advice to the National Health Service (NHS) and the Department of Health. The HPA also had a lead role in helping preparations for new and emerging health threats, such as a bioterrorism or in the event of an emerging virulent disease strain. There were four HPA centres – at Porton Down in Salisbury, Chilton in Didcot, South Mimms in Hertfordshire, and Colindale in NW London. In addition, the HPA had regional laboratories across England and administrative headquarte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

TETRA
Terrestrial Trunked Radio (TETRA; formerly known as Trans-European Trunked Radio), a European standard for a trunked radio system, is a professional mobile radio and two-way transceiver specification. TETRA was specifically designed for use by government agencies, emergency services, (police forces, fire departments, ambulance) for public safety networks, rail transport staff for train radios, transport services and the military. TETRA is the European version of trunked radio, similar to Project 25. TETRA is a European Telecommunications Standards Institute (ETSI) standard, first version published 1995; it is mentioned by the European Radiocommunications Committee (ERC). Description TETRA uses time-division multiple access (TDMA) with four user channels on one radio carrier and 25 kHz spacing between carriers. Both point-to-point and point-to-multipoint transfer can be used. Digital data transmission is also included in the standard though at a low data rate. TETRA Mob ...

The Post Office Electrical Engineers' Journal
''The Post Office Electrical Engineers' Journal'' (POEEJ) was a quarterly technical journal published by the Institution of Post Office Electrical Engineers between 1908 and 1982. 74 volumes were published in all. When Post Office Telecommunications became British Telecom in 1981, shortly before the latter's privatisation, the Institution changed its name to the Institution of British Telecommunications Engineers. Publication of the POEEJ then ceased in favour of a new journal, ''British Telecommunications Engineering''. The POEEJ documented the development of Britain's telecommunications network throughout most of the 20th century. Special issues marked key events such as the end of World War II, the construction of TAT-1 and the introduction of Subscriber trunk dialling. According to one source, in 1972 the journal had 38,000 readers, of which about 4,500 were not Post Office employees.''How the Secret Telephone War Came to Britain''. Sunday Times, October 15th 1972.

Leeds
Leeds () is a city and the administrative centre of the City of Leeds district in West Yorkshire, England. It is built around the River Aire and is in the eastern foothills of the Pennines. It is also the third-largest settlement (by population) in England, after London and Birmingham. The city was a small manorial borough in the 13th century and a market town in the 16th century. It expanded by becoming a major production centre, including of carbonated water where it was invented in the 1760s, and trading centre (mainly with wool) for the 17th and 18th centuries. It was a major mill town during the Industrial Revolution. It was also known for its flax industry, iron foundries, engineering and printing, as well as shopping, with several surviving Victorian era arcades, such as Kirkgate Market. City status was awarded in 1893, a populous urban centre formed in the following century which absorbed surrounding villages and overtook the nearby York population. It is locate ...

British Telecom Microwave Network
The British Telecom microwave network was a network of point-to-point microwave radio links in the United Kingdom, operated at first by the General Post Office, and subsequently by its successor BT plc. From the late 1950s to the 1980s it provided a large part of BT's trunk communications capacity, and carried telephone, television and radar signals and digital data, both civil and military. Its use of line-of-sight microwave transmission was particularly important during the Cold War for its resilience against nuclear attack. It was rendered obsolete, at least for normal civilian purposes, by the installation of a national optical fibre communication network with considerably higher reliability and vastly greater capacity. BT remains one of the largest owners of transmission and microwave towers in the UK. The most famous of these is the BT Tower in London, which was the tallest building in the UK from its construction in the 1960s until the early 1980s, and a major node in the BT ...
