FOMA SA800i
Freedom of Mobile Multimedia Access (FOMA) is the brand name of the W-CDMA-based 3G telecommunications services being offered by the Japanese telecommunications service provider NTT DoCoMo. It is an implementation of the Universal Mobile Telecommunications System (UMTS) and was the world's first 3G mobile data service to commence commercial operations. NTT DoCoMo also offers High Speed Packet Access, HSPA services branded FOMA High-Speed (FOMAハイスピード), which offers downlink speeds up to 7.2 Mbit/s and uplink speeds up to 5.7 Mbit/s. History NTT DoCoMo developed the W-CDMA air interface, which is a form of DS-CDMA (Direct Sequence CDMA), in the late 1990s. It was later accepted by the International Telecommunication Union, ITU as one of several air interfaces for the IMT-2000telecom initiative and by the ETSI as one of three air interfaces for the UMTS cellular network standard. NTT DoCoMo originally planned to launch the world's first 3G services, initially branded F ...

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 ...

Crash (computing)
In computing, a crash, or system crash, occurs when a computer program such as a software application or an operating system stops functioning properly and exits. On some operating systems or individual applications, a crash reporting service will report the crash and any details relating to it (or give the user the option to do so), usually to the developer(s) of the application. If the program is a critical part of the operating system, the entire system may crash or hang, often resulting in a kernel panic or fatal system error. Most crashes are the result of a software bug. Typical causes include accessing invalid memory addresses, incorrect address values in the program counter, buffer overflow, overwriting a portion of the affected program code due to an earlier bug, executing invalid machine instructions (an illegal opcode), or triggering an unhandled exception. The original software bug that started this chain of events is typically considered to be the cause of the ...

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)." To accommodate the reality that th ...

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 ...

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 ...

Product Recall
A product recall is a request from a manufacturer to return a product after the discovery of safety issues or product defects that might endanger the consumer or put the maker/seller at risk of legal action. The recall is an effort to limit ruination of the corporate image and limit liability for corporate negligence, which can cause significant legal costs. It can be difficult, if not impossible, to determine how costly can be releasing to the consumer a product that could endanger someone's life and the economic loss resulting from unwanted publicity. Recalls are costly. Costs include having to handle the recalled product, replacing it and possibly being held financially responsible for the consequences of the recalled product. A country's consumer protection laws will have specific requirements in regard to product recalls. Such regulations may include how much of the cost the maker will have to bear, situations in which a recall is compulsory (usually because the risk is b ...
