Universal Mobile Telecommunications System
The Universal Mobile Telecommunications System (UMTS) is a third generation mobile cellular system for networks based on the GSM standard. Developed and maintained by the 3GPP (3rd Generation Partnership Project), UMTS is a component of the International Telecommunication Union IMT-2000 standard set and compares with the CDMA2000 standard set for networks based on the competing cdmaOne technology. UMTS uses wideband code-division multiple access (W-CDMA) radio access technology to offer greater spectral efficiency and bandwidth to mobile network operators. UMTS specifies a complete network system, which includes the radio access network (UMTS Terrestrial Radio Access Network, or UTRAN), the core network (Mobile Application Part, or MAP) and the authentication of users via SIM (subscriber identity module) cards. The technology described in UMTS is sometimes also referred to as Freedom of Mobile Multimedia Access (FOMA) or 3GSM. Unlike EDGE (IMT Single-Carrier, based on GSM) and ...

I-mode
NTT DoCoMo's i-mode is a mobile internet (distinct from wireless internet) service popular in Japan. Unlike Wireless Application Protocols, i-mode encompasses a wider variety of internet standards, including web access, e-mail, and the packet-switched network that delivers the data. i-mode users also have access to other various services such as: sports results, weather forecasts, games, financial services, and ticket booking. Content is provided by specialised services, typically from the mobile carrier, which allows them to have tighter control over billing. Like WAP, i-mode delivers only those services that are specifically converted for the service, or are converted through gateways. Description In contrast with the Wireless Application Protocol (WAP) standard, which used Wireless Markup Language (WML) on top of a protocol stack for wireless handheld devices, i-mode borrows from DoCoMo proprietary protocols ALP (HTTP) and TLP ( TCP, UDP), as well as fixed Internet data ...

Brand Name
A brand is a name, term, design, symbol or any other feature that distinguishes one seller's good or service from those of other sellers. Brands are used in business, marketing, and advertising for recognition and, importantly, to create and store value as brand equity for the object identified, to the benefit of the brand's customers, its owners and shareholders. Brand names are sometimes distinguished from Generic brand, generic or store brands. The practice of branding - in the original literal sense of marking by burning - is thought to have begun with the ancient Egyptians, who are known to have engaged in livestock branding as early as 2,700 BCE. Branding was used to differentiate one person's cattle from another's by means of a distinctive symbol burned into the animal's skin with a hot branding iron. If a person stole any of the cattle, anyone else who saw the symbol could deduce the actual owner. The term has been extended to mean a strategic personality for a produ ...

Information Security
Information security, sometimes shortened to InfoSec, is the practice of protecting information by mitigating information risks. It is part of information risk management. It typically involves preventing or reducing the probability of unauthorized/inappropriate access to data, or the unlawful use, disclosure, disruption, deletion, corruption, modification, inspection, recording, or devaluation of information. It also involves actions intended to reduce the adverse impacts of such incidents. Protected information may take any form, e.g. electronic or physical, tangible (e.g. paperwork) or intangible (e.g. knowledge). Information security's primary focus is the balanced protection of the confidentiality, integrity, and availability of data (also known as the CIA triad) while maintaining a focus on efficient policy implementation, all without hampering organization productivity. This is largely achieved through a structured risk management process that involves: * identifying inform ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telecommunications In Japan
The nation of Japan currently possesses one of the most advanced communication networks in the world. For example, by 2008 the Japanese government's Internal Affairs and Communications Ministry stated that about 75 million people used mobile phones to access the Internet, said total accounting for about 82% of individual Internet users. Overview of communication services Telephone services Telephones and ISDN – main lines in use: 52.3981 million (2007) IP phone lines in use: 16.766 million (2007) Mobile and PHS lines in use: 105.297 million (2007) :''international:'' satellite earth stations – 5 Intelsat (4 Pacific Ocean and 1 Indian Ocean), 1 Intersputnik (Indian Ocean region), and 1 Inmarsat (Pacific and Indian Ocean regions); submerged cables to China, Philippines, Russia, and US (via Guam) Mobile phone services There are four nationwide mobile phone service providers: NTT DoCoMo, KDDI, Ymobile, and Rakuten mobile.

Personal Digital Cellular
Personal Digital Cellular (PDC) was a 2G mobile telecommunications standard used exclusively in Japan. After a peak of nearly 80 million subscribers to PDC, it had 46 million subscribers in December 2005, and was slowly phased out in favor of 3G technologies like W-CDMA and CDMA2000. At the end of March 2012, the count had dwindled down to almost 200,000 subscribers. NTT Docomo shut down their network, mova, on April 1, 2012 at midnight. Technical overview Like D-AMPS and GSM, PDC uses TDMA. The standard was defined by the RCR (later became ARIB) in April 1991, and NTT DoCoMo launched its Digital mova service in March 1993. PDC uses 25 kHz carrier, pi/4-DQPSK modulation with 3-timeslot 11.2 kbit/s (full-rate) or 6-timeslot 5.6 kbit/s (half-rate) voice codecs. PDC is implemented in the 800 MHz (downlink 810–888 MHz, uplink 893–958 MHz), and 1.5 GHz (downlink 1477–1501 MHz, uplink 1429–1453 MHz) bands. The air interface is ...

UMTS Frequency Bands
The UMTS frequency bands are radio frequencies used by third generation (3G) wireless Universal Mobile Telecommunications System networks. They were allocated by delegates to the World Administrative Radio Conference (WARC-92) held in Málaga-Torremolinos, Spain between 3 February 1992 and 3 March 1992. Resolution 212 (Rev.WRC-97), adopted at the World Radiocommunication Conference held in Geneva, Switzerland in 1997, endorsed the bands specifically for the International Mobile Telecommunications-2000 (IMT-2000) specification by referring to S5.388, which states "The bands 1,885-2,025 MHz and 2,110-2,200 MHz are intended for use, on a worldwide basis, by administrations wishing to implement International Mobile Telecommunications 2000 (IMT-2000). Such use does not preclude the use of these bands by other services to which they are allocated. The bands should be made available for IMT-2000 in accordance with Resolution 212 (Rev. WRC-97)."

Early Adopter (marketing)
An early adopter or lighthouse customer is an early customer of a given company, product, or technology. The term originates from Everett M. Rogers' ''Diffusion of Innovations'' (1962). History Typically, early adopters are customers who, in addition to using the vendor's product or technology, also provide considerable and candid feedback to help the vendor refine its future product releases, as well as the associated means of distribution, service, and support. Early adoption could also be referred to as a form of testing in the early stages of a project. The relationship is synergistic. The customer receives early (and sometimes unique, or at least uniquely early) access to an advantageous new product or technology. In return, the customer may also serve as a kind of guinea pig. In exchange for being an early adopter, and thus being exposed to the problems, risks, and annoyances common to early-stage product testing and deployment, the "lighthouse customer" is sometimes give ...
