Au (mobile Phone Operator)
au, or au by KDDI, is a Japanese mobile phone operator. au is a brand marketed by KDDI in the main islands of Japan and by Okinawa Cellular in Okinawa for their mobile cellular services. au is the second-largest wireless carrier in Japan, with 60.398 million subscribers as of March 2021. Naming According to the brand creator, the name 'au' is based on the Japanese verbs for 'meet' (会う) and 'unite' (合う) (both pronounced 'au'). However, KDDI explains that au comes from two letters which stand for few words. 'A' is for access, always and amenity, and 'U' is for unique, universal and user. There is also a phrase, 'access to u(you)' that goes along the brand name. History The network that would eventually become Au was originally set up as two networks: DDI and IDO. IDO's network was based upon the NTT Hi-cap analog cellular system, and began operations in December 1988 in the Kanto and Tokai regions. DDI's network was run by independent phone companies, and began service ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Short Message Service
Short Message/Messaging Service, commonly abbreviated as SMS, is a text messaging service component of most telephone, Internet and mobile device systems. It uses standardized communication protocols that let mobile devices exchange short text messages. An intermediary service can facilitate a text-to-voice conversion to be sent to landlines. SMS technology originated from radio telegraphy in radio memo pagers that used standardized phone protocols. These were defined in 1986 as part of the Global System for Mobile Communications ( GSM) series of standards.GSM Doc 28/85 "Services and Facilities to be provided in the GSM System" rev2, June 1985 The first SMS message was sent on 3 December 1992, when Neil Papworth, a test engineer for Sema Group, sent "Merry Christmas" to the Orbitel 901 phone of colleague Richard Jarvis. SMS rolled out commercially on many cellular networks that decade and became hugely popular worldwide as a method of text communication. By the end of 2010 ...

1seg
is a mobile terrestrial digital audio/video and data broadcasting service in Japan, Argentina, Brazil, Chile, Uruguay, Paraguay, Peru and the Philippines. Service began experimentally during 2005 and commercially on April 1, 2006. It is designed as a component of ISDB-T, the terrestrial digital broadcast system used in those countries, as each channel is divided into 13 segments, with a further segment separating it from the next channel; an HDTV broadcast signal occupies 12 segments, leaving the remaining (13th) segment for mobile receivers, hence the name, "1seg" or "One Seg". Its use in Brazil was established in late 2007 (starting in just a few cities), with a slight difference from the Japanese counterpart: it is broadcast under a 30 frame/s transmission setting (Japanese broadcasts are under the 15 frame/s transmission setting). Technical information The ISDB-T system uses the UHF band at frequencies between 470 and 770 MHz (806 MHz in Brazil), giving a tot ...

BCMCS
Broadcast and Multicast Service (BCMCS) is an interface for providing broadcast and multicast services in 3GPP2 CDMA2000 mobile networks. BCMCS can be used to transfer light video and audio clips or other data to a large group of mobile subscribers in an efficient manner. To do so, BCMCS is a so-called point-to-multipoint service. This means that multiple users receive the same information using the same radio resources. Usage of BCMCS BCMCS can be used for two different kind of services. Broadcast services in which all users within the broadcasting area can receive the same information and a multicast services in which only users that have subscribed to the service can receive the information Although BCMCS can be used for mobile TV, it has some limitations in the capacity that can be used for this kind of services within the network. Enhanced Broadcast and Multicast Services EBCMCS is an enhanced version of BCMCS. EBCMCS uses a new radio interface based on OFDM In ...

Ringback Tone
Ringing tone (audible ringing, also ringback tone) is a signaling tone in telecommunication that is heard by the originator of a telephone call while the destination terminal is alerting the receiving party. The tone is typically a repeated cadence similar to a traditional power ringing signal (''ringtone''), but is usually not played synchronously. Various telecommunication groups, such as the Bell System and the General Post Office (GPO) developed standards, in part taken over by the European Telecommunications Standards Institute (ETSI) and other standards bodies. With modern cell phone and smartphone technology ringing tone can be customized and even used for advertising. Purpose and description When a telephone user initiates a telephone call, typically by dialing or selecting a telephone number on a telephone, the progress or status of the call attempt is indicated to the user audibly by a several types of call progress tones. For example, during the period of routing the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Binary Runtime Environment For Wireless
Binary Runtime Environment for Wireless (Brew MP, Brew, Qualcomm BREW, or BREW) is an application development platform created by Qualcomm, originally for code division multiple access (CDMA) mobile phones, featuring third-party applications such as mobile games. It is offered in some feature phones (mostly with specifications similar to those of mid to high-end mobile phones) but not in smartphones. First developed in 1999, as a platform for wireless applications on CDMA-based mobile phones, it debuted in September 2001. As a software platform that can download and run small programs for playing games, sending messages, and sharing photos, the main advantage of Brew MP is that the application developers can easily port their applications among all Brew MP devices by providing a standardized set of application programming interfaces. Software for Brew MP enabled handsets can be developed in C or C++ using the freely downloadable Brew MP software development kit (SDK). The BREW runt ...

CPRM
Content Protection for Recordable Media and Pre-Recorded Media (CPRM / CPPM) is a mechanism for controlling the copying, moving, and deletion of digital media on a host device, such as a personal computer, or other player. It is a form of digital rights management (DRM) developed by The 4C Entity, LLC (consisting of IBM, Intel, Matsushita and Toshiba). The CPRM / CPPM specification defines a renewable cryptographic method for restricting content when recorded on physical media. The currently implemented method utilizes the Cryptomeria cipher (C2) algorithm for symmetric encryption. The types of physical media supported include, but are not limited to, recordable DVD media and flash memory. The most widespread use of CPRM is arguably in Secure Digital cards such as the SD-Audio standard. Note that the available 0.9 revision includes only the portions of the specification covering DVD media. The CPRM / CPPM specification was designed to meet the requirements of intellectu ...
