Rich Communication Services
Rich Communication Services (RCS) is a communication protocol standard for instant messaging, primarily for mobile phones, developed and defined by the GSM Association (GSMA). It aims to be a replacement of SMS and Multimedia Messaging Service, MMS on cellular networks with more modern features including high resolution image and video support, typing indicators, file sharing, and improved group chat functionality. Development of RCS began in 2007 but early versions lacked features and interoperability; a new specification named Universal Profile was developed and has been continually rolled out since 2017. RCS has been designed as an industry open standard to provide improved capabilities over basic text messaging, based on the Internet Protocol (IP). Its development has also been supported by mobile network operators to regain their influence against individual OTT (over-the-top) chat apps and services. Additional features of RCS include presence information, location and multi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mobile World Congress
MWC Barcelona (formerly but still commonly referred to as Mobile World Congress) is an annual trade show dedicated to the mobile communications industry. The event is held in L'Hospitalet de Llobregat, Spain, at the Fira de Barcelona Gran Via, usually in February or early March. It is attended primarily by device manufacturers, network equipment providers, representatives of wireless carriers, and the press, among others. Its annual attendance is generally around 100,000 people, while mobile phone manufacturers often use the conference to unveil upcoming devices. The event is organised by the GSM Association (GSMA). GSMA has extended the MWC brand to four other trade shows in Shanghai, China (MWC Shanghai), Kigali, Rwanda (MWC Kigali, formerly MWC Africa) Las Vegas, United States (MWC Las Vegas, formerly MWC Los Angeles), and Doha, Qatar (MWC Doha) but the brand remains most synonymous with the Barcelona event.

Voice Over LTE
Voice over Long-Term Evolution (acronym VoLTE) is an LTE high-speed wireless communication standard for voice calls and SMS using mobile phones and data terminals. VoLTE has up to three times more voice and data capacity than older 3G UMTS and up to six times more than 2G GSM. It uses less bandwidth because VoLTE's packet headers are smaller than those of unoptimized VoIP/LTE. VoLTE calls are usually charged at the same rate as other calls. To be able to make a VoLTE call, the device, its firmware, and the mobile telephone providers on each end, as well as the inter-carrier connectivity must all implement the service in the area, and be able to work together. VoLTE has been marketed as "HD voice" by some carriers, but this is a broader concept. Moreover, HD+ ( EVS) is used only in LTE and NR; HD voice was available in 3G too. Overview VoLTE is based on the IP Multimedia Subsystem (IMS) architectural framework, with specific profiles for control and media planes of voice ...

IMEI
The International Mobile Equipment Identity (IMEI) is a numeric identifier, usually Unique identifier, unique, for 3GPP and iDEN mobile phones, as well as some satellite phones. It is usually found printed inside the battery compartment of the phone but can also be displayed on-screen on most phones by entering the Unstructured Supplementary Service Data#Code table, MMI Supplementary Service code *#06# on the dialpad, or alongside other system information in the settings menu on smartphone operating systems. GSM networks use the IMEI number to identify valid devices, and can stop a stolen phone from accessing the network. For example, if a mobile phone is stolen, the owner can have their network provider use the IMEI number to blocklist the phone. This renders the phone useless on that network and sometimes other networks, even if the thief changes the phone's subscriber identity module, SIM card. Devices without a SIM card slot or eSIM capability usually do not have an IMEI, exc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

GSM Standard
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Organizations Established In 1995
An organization or organisation ( Commonwealth English; see spelling differences) is an entity—such as a company, or corporation or an institution ( formal organization), or an association—comprising one or more people and having a particular purpose. Organizations may also operate secretly or illegally in the case of secret societies, criminal organizations, and resistance movements. And in some cases may have obstacles from other organizations (e.g.: MLK's organization). What makes an organization recognized by the government is either filling out incorporation or recognition in the form of either societal pressure (e.g.: Advocacy group), causing concerns (e.g.: Resistance movement) or being considered the spokesperson of a group of people subject to negotiation (e.g.: the Polisario Front being recognized as the sole representative of the Sahrawi people and forming a partially recognized state.)

Telecommunications Organizations
Telecommunication, often used in its plural form or abbreviated as telecom, is the transmission of information over a distance using electronic means, typically through cables, radio waves, or other communication technologies. These means of transmission may be divided into communication channels for multiplexing, allowing for a single medium to transmit several concurrent communication sessions. Long-distance technologies invented during the 20th and 21st centuries generally use electric power, and include the telegraph, telephone, television, and radio. Early telecommunication networks used metal wires as the medium for transmitting signals. These networks were used for telegraphy and telephony for many decades. In the first decade of the 20th century, a revolution in wireless communication began with breakthroughs including those made in radio communications by Guglielmo Marconi, who won the 1909 Nobel Prize in Physics.
