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.
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, 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.
Integrated Digital Enhanced Network (iDEN) is a mobile telecommunications technology, developed by Motorola, which provides its users the benefits of a trunked radio and a cellular telephone. It was called the first mobile social network by many technology industry analysts. iDEN places more users in a given spectral space, compared to analog cellular and two-way radio systems, by using speech compression and time-division multiple access (TDMA).
NMT is an automatic cellular phone system specified by Nordic telecommunications administrations (PTTs) and opened for service on 1 October 1981. NMT is based on analogue technology 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.
A satellite telephone, satellite phone or satphone is a type of mobile phone that connects to other phones or the telephone network by radio through orbiting satellites instead of terrestrial cell sites, as cellphones do. The advantage of a satphone is that its use is not limited to areas covered by cell towers; it can be used in most or all geographic locations on the Earth's surface.
GSM frequency bands or frequency ranges are the cellular frequencies designated by the ITU for the operation of GSM mobile phones and other mobile devices.
PT Telkom Indonesia (Persero) Tbk, also simply known as Telkom, is an Indonesian multinational telecommunications conglomerate. Telkom is listed on the Indonesia Stock Exchange and has a secondary listing on the New York Stock Exchange. The government of Indonesia owns over half of Telkom's shares outstanding.
Mobile telephony is the provision of telephone services to phones which may move around freely rather than stay fixed in one location. Telephony is supposed to specifically point to a voice-only service or connection, though sometimes the line may blur.
The features of mobile phones are the set of capabilities, services and applications that they offer to their users. Mobile phones are often referred to as feature phones, and offer basic telephony. Handsets with more advanced computing ability through the use of native code try to differentiate their own products by implementing additional functions to make them more attractive to consumers. This has led to great innovation in mobile phone development over the past 20 years.
Generic Access Network (GAN) is a protocol that extends mobile voice, data and multimedia applications over IP networks. Unlicensed Mobile Access (UMA) is the commercial name used by mobile carriers for external IP access into their core networks. The latest generation system is named Wi-Fi Calling or VoWiFi by a number of handset manufacturers, including Apple and Samsung, a move that is being mirrored by carriers like T-Mobile US and Vodafone. The service is dependent on IMS, IPsec, IWLAN and ePDG.
SkyTerra (SKYT), formerly Mobile Satellite Ventures, was a Reston, Virginia company that developed telecommunications systems that integrate satellite and terrestrial radio communication technologies into one system. In March 2010, the company was acquired by Harbinger Capital Partners and under the leadership of CEO Sanjiv Ahuja became part of a new company called LightSquared. The company placed its first satellite, SkyTerra-1, in orbit on November 14, 2010. LightSquared has since then went bankrupt and emerged from bankruptcy as Ligado Networks.
The 3GPP has defined the Voice Call Continuity (VCC) specifications in order to describe how a voice call can be persisted, as a mobile phone moves between circuit switched and packet switched radio domains.
Dual-mode mobiles refer to mobile phones that are compatible with more than one form of data transmission or network.
The Ericsson R290 is a combined GSM and satellite phone using the Globalstar satellite network. The R290 was introduced in June 1999 and manufactured in the United Kingdom by Ericsson Mobile Communications.
TerreStar Networks, a majority owned subsidiary of TerreStar Corporation (TSTR), is a next generation, wholesale mobile communications provider launching the first integrated satellite terrestrial service with the world's first satellite-terrestrial smartphone.
The history of the prepaid mobile phone began in the 1990s when mobile phone operators sought to expand their market reach. Up until this point, mobile phone services were exclusively offered on a postpaid basis (contract-based), which excluded individuals with poor credit ratings and minors under the age of 18 In early 1991, Kenneth Johnson of Queens, New York, President of Alicomm Mobile, was the first to successfully create a prepaid cellular phone and Network. His company expanded to a Sales force from Maine to Florida. Two years later others would come out with similar systems.
Agila-1 or Mabuhay was launched on March 20, 1987, under the name Palapa B2-P in Cape Canaveral Air Force Station. It was originally under Indonesian company, PT Pasifik Satelit Nusantara until it was acquired by Philippine company, Mabuhay Satellite Corporation which is under PLDT in 1996. Upon its acquisition by Mabuhay, it became the first Philippine satellite through acquisition while in orbit. Palapa B2-P was later renamed to "Agila-1", the local name for the Philippine eagle. The satellite's operation ended in January 1998 and was deorbited.
PT Pasifik Satelit Nusantara (PSN) is an Indonesian satellite communication company.
Nusantara Satu is an Indonesian communications satellite. It is a large high-throughput satellite (HTS) providing voice and data communications, and Internet access throughout the Indonesian archipelago and Southeast Asia.
Nusantara most commonly refers to:
