C-Netz
The Radio Telephone Network C (German: Funktelefonnetz-C, abbreviated as C-Netz), was a first generation analog cellular phone system deployed and operated in Germany (at first West Germany) by DeTeMobil (formerly of Deutsche Bundespost Telekom, currently Deutsche Telekom). It utilized the C-450 standard, originally developed by Siemens AG, and was the third and last update of a series of analog mobile phone systems used primarily within Germany, superseding the B-Netz and the A-Netz before it. It has been decommissioned, replaced by both the newer ''D-Netz'' and ''E-Netz'' systems, both based on GSM standards (which are digital) and operating on 900 MHz and 1800 MHz bands respectively. C-Netz was active from 1985 to 2000, with certain areas until 2001. Since then, all consumer cellular phone services in Germany are digital-only. The dialing code for the C-Netz was 0161, which is no longer in use. As a result, users were not able to transfer their numbers to GSM n ...

T-Mobile
T-Mobile is the brand name used by some of the mobile communications subsidiaries of the German telecommunications company Deutsche Telekom AG in the Czech Republic (T-Mobile Czech Republic), Poland (T-Mobile Polska), the United States (T-Mobile US) and by the former subsidiary in the Netherlands (T-Mobile Netherlands). The T-Mobile brand was introduced in 1996 and the name was previously used by subsidiaries in other countries, including Austria (now Magenta), Croatia (now Hrvatski Telekom), Germany (now Deutsche Telekom), Hungary (now Magyar Telekom), Montenegro (now Crnogorski Telekom), North Macedonia (now Makedonski Telekom), Romania (now Telekom România), Slovakia (now Slovak Telekom), and the United Kingdom (now EE Limited). In 1999, Deutsche Telekom formed the holding company T-Mobile International AG for its mobile communications subsidiaries. From 2003 to 2007, T-Mobile International was one of Deutsche Telekom's services, in addition to "Broadband/Fixnet", "Busines ...

B-Netz
B-Netz was an analog, commercial mobile radio telephone network that was operated by the Deutsche Bundespost in Germany (at first only West Germany) from 1972 until 1994. The system was also implemented in neighboring countries Austria, The Netherlands and Luxembourg. The B refers to the fact that it was the country's second public mobile telephone network, following the A-Netz. As opposed to its predecessor, it featured direct-dialing (so that human operators were not required to connect calls). The frequency plan originally included only 38 channels (with one call possible per frequency channel), but it was upgraded to incorporate the A-Netz frequencies when that network was retired in 1980. The upgraded network had 78 channels and is sometimes referred to as the B2-Netz. A major limitation of system was that, in order to reach a subscriber, one had to know his location since the handset would assume the local area code of the base station serving it. Handoff was not possible ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nordic Mobile Telephone
NMT (''Nordic Mobile Telephony'') 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 (first generation or 1G) 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. The NMT specifications were free and open, allowing many companies to produce NMT hardware and pushing prices down. The success of NMT was important to Nokia (then Mobira) and Ericsson. First Danish implementers were Storno (then owned by General Electric, later taken over by Motorola) and AP (later taken over by Philips). Initial NMT phones were designed to mount in the trunk of a car, with a keyboard/display unit at the driver's seat. "Portable" versions existed, though they were still bulky, and with battery life a big problem. Later models such as Benefon's we ...

Flash-OFDM
In telecommunications, orthogonal frequency-division multiplexing (OFDM) is a type of digital transmission and a method of encoding digital data on multiple carrier frequencies. OFDM has developed into a popular scheme for wideband digital communication, used in applications such as digital television and audio broadcasting, DSL internet access, wireless networks, power line networks, and 4G/ 5G mobile communications. OFDM is a frequency-division multiplexing (FDM) scheme that was introduced by Robert W. Chang of Bell Labs in 1966. In OFDM, multiple closely spaced orthogonal subcarrier signals with overlapping spectra are transmitted to carry data in parallel.webe.org - 2GHz BAS Relocation Tech-Fair, COFDM Technology Basics 2007-03-02 Demodulat ...

List Of Dialling Codes In Germany
Area codes in Germany (german: Vorwahl) have two to five digits. In addition, the prefix digit ''0'' must be dialed when calling from within Germany, and must be omitted when calling from abroad. When calling via fixed networks within the same area, the area code is not required. In general, shorter area codes are assigned to larger cities, and longer area codes to smaller towns. Subscriber telephone numbers are usually inversely long: those in larger cities have seven or eight digits, while those in smaller towns may have as few as three or four digits. Area codes are grouped into eight geographic dialing regions determined by the first digit (''2''–''9''). Area codes beginning with 2 are found in the west, those with 3 in the east, those with 4 in the north, those with 5 in the north central part, those with 6 in the south central part, those with 7 in the southwest, those with 8 in the south, and the 9s are found in the southeast. Prefixes starting with 1 are special numbers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roaming
Roaming is a wireless telecommunication term typically used with mobile devices, such as mobile phones. It refers to a mobile phone being used outside the range of its native network and connecting to another available cell network. Technical definition In more technical terms, roaming refers to ''the ability for a cellular customer to automatically make and receive voice calls, send and receive data, or access other services, including home data services, when travelling outside the geographical coverage area of the home network, by means of using a visited network''. For example: should a subscriber travel beyond their cell phone company's transmitter range, their cell phone would automatically hop onto another phone company's service, if available. The process is supported by the Telecommunication processes of mobility management, authentication, authorization and accounting billing procedures (known as AAA or 'triple A'). Roaming in general Roaming is divided into "S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Taxicab
A taxi, also known as a taxicab or simply a cab, is a type of vehicle for hire with a driver, used by a single passenger or small group of passengers, often for a non-shared ride. A taxicab conveys passengers between locations of their choice. This differs from public transport where the pick-up and drop-off locations are decided by the service provider, not by the customers, although demand responsive transport and share taxis provide a hybrid bus/taxi mode. There are four distinct forms of taxicab, which can be identified by slightly differing terms in different countries: * Hackney carriages, also known as public hire, hailed or street taxis, licensed for hailing throughout communities * Private hire vehicles, also known as minicabs or private hire taxis, licensed for pre-booking only * Taxibuses, also come in many variations throughout the developing countries as jitneys or jeepney, operating on pre-set routes typified by multiple stops and multiple independent passenger ...
