Norwegian Public Safety Network
The Norwegian Public Safety Network ( literally ''Emergency Network'') is a public safety network system based on Terrestrial Trunked Radio (TETRA). Nødnett is implemented by the Directorate for Emergency Communication (). The network is primarily used for internal and interdisciplinary communication by the police, fire departments and health services. Nødnett is also used by several organisations participating in rescue and emergency work. Planning of the network started in 1995 and in 2006 the contract to build it was awarded to Nokia Siemens Networks. As Nokia Siemens Networks was unable to complete the contract, it was passed on to Motorola Solutions in 2012. The critical infrastructure of Nødnett was finished and was operational in all districts of mainland Norway by December 1, 2015. The network replaced nearly 300 local and regional networks which operated independently for the fire, police and healthcare agencies. Nødnett allows functionality such as authentication, ...

Encrypted Communication
Secure communication is when two entities are communicating and do not want a third party to listen in. For this to be the case, the entities need to communicate in a way that is unsusceptible to eavesdropping or Signals intelligence, interception. Secure communication includes means by which people can share information with varying degrees of certainty that third parties cannot intercept what is said. Other than spoken face-to-face communication with no possible eavesdropper, it is probable that no communication is guaranteed to be secure in this sense, although practical obstacles such as legislation, resources, technical issues (interception and encryption), and the sheer volume of communication serve to limit surveillance. With many communications taking place over long distance and mediated by technology, and increasing awareness of the importance of interception issues, technology and its compromise are at the heart of this debate. For this reason, this article focuses on co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nordic Mobile Telephone
NMT (''Nordic Mobile Telephony'') is an automatic cellular phone system specified by Nordic countries, Nordic telecommunications administrations (Postal Telephone and Telegraph, PTTs) and opened for service on 1 October 1981. NMT is based on analog signal, analogue technology (first generation or 1G) and two variants exist: NMT-450 and NMT-900. The numbers indicate the frequency bands used. NMT-900 was introduced in 1986 and carries more channels than the older NMT-450 network. The NMT specifications were free and open, allowing many companies to produce NMT hardware and pushing prices down. The success of NMT was important to Nokia (then Mobira) and Ericsson. The first Danish implementers were Storno (then owned by General Electric, later taken over by Motorola) and AP (later taken over by Philips). Initial NMT phones were designed to mount in the trunk of a car, with a keyboard/display unit at the driver's seat. "Portable" versions existed, though they were still bulky, and wit ...

Global System For Mobile Communication
The Global System for Mobile Communications (GSM) is a family of standards to describe the protocols for second-generation ( 2G) digital cellular networks, as used by mobile devices such as mobile phones and mobile broadband modems. GSM is also a trade mark owned by the GSM Association. "GSM" may also refer to the voice codec initially used in GSM. 2G networks developed as a replacement for first generation ( 1G) analog cellular networks. The original GSM standard, which was developed by the European Telecommunications Standards Institute (ETSI), originally described a digital, circuit-switched network optimized for full duplex voice telephony, employing time division multiple access (TDMA) between stations. This expanded over time to include data communications, first by circuit-switched transport, then by packet data transport via its upgraded standards, GPRS and then EDGE. GSM exists in various versions based on the frequency bands used. GSM was first implemented in Finlan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Midwive
A midwife (: midwives) is a health professional who cares for mothers and newborns around childbirth, a specialisation known as midwifery. The education and training for a midwife concentrates extensively on the care of women throughout their lifespan; concentrating on being experts in what is normal and identifying conditions that need further evaluation. In most countries, midwives are recognised as skilled healthcare providers. Midwives are trained to recognise variations from the normal progress of labour and understand how to deal with deviations from normal. They may intervene in high risk situations such as breech births, twin births, using non-invasive techniques. For complications related to pregnancy and birth that are beyond the midwife's scope of practice, including surgical and instrumental deliveries, they refer their patients to physicians or surgeons. In many parts of the world, these professions work in tandem to provide care to childbearing women. In others, o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
