Telecommunications In Ukraine
Telecommunications is one of the most modern, diverse and fast-growing sectors in the economy of Ukraine. Unlike the country's dominating export industries, telecommunications, as well as the related Internet sector, remain largely unaffected by the global economic crisis, ranking high in European and global rankings. The industry also leads in demonopolization of Ukraine's economy as Ukrtelekom (once the country's sole telephone provider) was successfully privatized, and is now losing its retail market share to independent, foreign-invested private providers. The entire population of Ukraine now has telephone and/or mobile phone connection; Internet access is universally available in cities and main transport corridors, expanding into smaller settlements. Ukraine's telecommunication development plan emphasizes further improving domestic trunk lines, international connections, and the mobile cellular system. During the Russian invasion of Ukraine, telecommunications were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Starlink Satellite Services In Ukraine

High-Speed Uplink Packet Access
High Speed Packet Access (HSPA) is an amalgamation of two mobile protocols—High Speed Downlink Packet Access (HSDPA) and High Speed Uplink Packet Access (HSUPA)—that extends and improves the performance of existing 3G mobile telecommunication networks using the WCDMA protocols. A further-improved 3GPP standard called Evolved High Speed Packet Access (also known as HSPA+) was released late in 2008, with subsequent worldwide adoption beginning in 2010. The newer standard allows bit rates to reach as high as 337 Mbit/s in the downlink and 34 Mbit/s in the uplink; however, these speeds are rarely achieved in practice. Overview The first HSPA specifications supported increased peak data rates of up to 14 Mbit/s in the downlink and 5.76 Mbit/s in the uplink. They also reduced latency and provided up to five times more system capacity in the downlink and up to twice as much system capacity in the uplink compared with original WCDMA protocol. High Speed Do ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Universal Mobile Telecommunications System
The Universal Mobile Telecommunications System (UMTS) is a 3G mobile cellular system for networks based on the GSM standard. UMTS uses wideband code-division multiple access (W-CDMA) radio access technology to offer greater spectral efficiency and bandwidth to mobile network operators compared to previous 2G systems like GPRS and CSD. UMTS on its provides a peak theoretical data rate of 2 Mbit/s. 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. The technology described in UMTS is sometimes also referred to as Freedom of Mobile Multimedia Access (FOMA) or 3GSM. 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 authenticat ...

Enhanced Data Rates For GSM Evolution
Enhanced Data rates for GSM Evolution (EDGE), also known as 2.75G and under various other names, is a 2G digital mobile phone technology for packet switched data transmission. It is a subset of General Packet Radio Service (GPRS) on the GSM network and improves upon it offering speeds close to 3G technology, hence the name 2.75G. EDGE is standardized by the 3GPP as part of the GSM family and as an upgrade to GPRS. EDGE was deployed on GSM networks beginning in 2003 – initially by Cingular (now AT&T) in the United States. It could be readily deployed on existing GSM and GPRS cellular equipment, making it an easier upgrade for cellular companies compared to the UMTS 3G technology that required significant changes. Through the introduction of sophisticated methods of coding and transmitting data, EDGE delivers higher bit-rates per radio channel, resulting in a threefold increase in capacity and performance compared with an ordinary GSM/GPRS connection - originally a max ...

GPRS
General Packet Radio Service (GPRS), also called 2.5G, is a mobile data standard on the 2G cellular communication network's Global System for Mobile Communications, global system for mobile communications (GSM). Networks and mobile devices with GPRS started to roll out around the year 2001; it offered, for the first time on GSM networks, seamless data transmission using Packet switching, packet data for an "always-on" connection (eliminating the need to "dial-up"), so providing improved Internet access for World Wide Web, web, email, Wireless Application Protocol, WAP services, Multimedia Messaging Service (MMS) and others. Up until the rollout of GPRS, only circuit switched data was used in cellular networks, meaning that one or more radio channels were occupied for the entire duration of a data connection. On the other hand, on GPRS networks, data is broken into small packets and transmitted through available channels. This increased efficiency also gives it theoretical data ...

Beeline Ukraine
Beeline () is a mobile network operator brand operating in Russia under PJSC VimpelCom, and in Kazakhstan, Kyrgyzstan and Uzbekistan under VEON Ltd. Beeline is Russia's fourth-largest mobile network operator, and main competitors being MTS, MegaFon and T2. Since 2009, PJSC VimpelCom had been a subsidiary of the Amsterdam based VimpelCom Ltd, which became VEON in 2017. On 9 October 2023, VEON sold Beeline in Russia and completed its exit from Russia, leaving the brand "Beeline" owned by PJSC VimpelCom in Russia and by VEON Ltd. in Kazakhstan, Kyrgyzstan and Uzbekistan. The commercial service was launched under the Beeline brand, a brand developed by Fabela in late 1993 to differentiate the company as a youthful and fun company, rather than a technical company. The name comes from the English term " beeline", meaning the most direct way between two points. VimpelCom relaunched Beeline with the current characteristic black-and-yellow striped circle in 2005 with a campaign to asso ...

Telephone
A telephone, colloquially referred to as a phone, is a telecommunications device that enables two or more users to conduct a conversation when they are too far apart to be easily heard directly. A telephone converts sound, typically and most efficiently the human voice, into electronic signals that are transmitted via Electrical cable, cables and other communication channels to another telephone which reproduces the sound to the receiving user. The term is derived from and (, ''voice''), together meaning ''distant voice''. In 1876, Alexander Graham Bell was the first to be granted a United States patent for a device that produced clearly intelligible replication of the human voice at a second device. This instrument was further developed by many others, and became rapidly indispensable in business, government, and in households. The essential elements of a telephone are a microphone (''transmitter'') to speak into and an earphone (''receiver'') which reproduces the voice a ...

Intersputnik
The Intersputnik International Organization of Space Communications, commonly known as Intersputnik, is an international satellite communications services organization founded on 15 November 1971, in Moscow by the Soviet Union along with a group of seven formerly socialist states (Poland, Czechoslovakia, East Germany, Hungary, Romania, Bulgaria, Mongolia) and Cuba. The objective was and continues to be the development and common use of communications satellites. It was created as the Eastern Bloc's response to the Western Intelsat organization. As of 2024, the organization has 25 member states. Ukraine is in the process of leaving the organization, while Czechia announced its intention to leave in February 2025, and Poland announced on 13 March 2025 that it will leave effective 12 August 2025. Intersputnik nowadays is a commercially aligned organization. It operates 12 satellites in orbit and 41 transponders. In June 1997 Intersputnik created the Lockheed Martin Intersputnik (LMI) ...
