ADSL Asymmetric Digital Subscriber Line enables on a basis of an asymmetrical transmission method a high-speed data transfer with conventional telephone wires (copper twin wire). ASDL is particularly suitable for user, who download large amounts of data i from the Web, but only upload relatively small amounts.
Android Greek language androides – “human like”, antrophoid: operating system which is used in many current smartphones, excluding Apple Iphone and Windows Phone. Lead-managed from Google since 2007.
App App ist the short form for application. The application program can be used on a mobile terminal (smartphone or tablet). Apps can be downloaded from the App-Store.
Bandwidth Transmission capacity of a line system, indicated in BIT/s or Mbit/s. Sufficiently bandwidth is essential for a guaranteed data communication.
Basic restrictions Specifies the maximum allowable value, which may affect the people with the electromagnetic fields. The basic restricions are expressed in the “Specific Absorption Rate” (SAR). As the SAR it is difficult to measure in practice, derived basic restricions are preferred. In order to take into account the protection of particularly sensitive people, the basic limit value includes safety surcharges.
Base station Transmission and reception system for mobile communication, that supplies limited area (radio cell).
Big data Big data refers to particularly large amounts of data, which can not (or insufficient) be processed with the help of standard databases and data management tools. They can be stored and evaluated using appropriate IT applications.
Bluetooth Bluetooth is a radio transmission of voice and data, used for short distances. Through Bluetooth, e. g.  PCs, fax machines and mobile phones can be connected wirelessly.
Call-by-Call The possibility to conduct and settle single telephone calls or Internet connections via a different provider than that of the telephone connection.
Cloud In cloud computing, the user receives what he previously had locally on his computer, f. e. text programs, anti-virus software or memory. Regardless of where the user is currently located or which terminal (PC, notebook, tablet or smartphone) he is currently using. The key is simply an Internet access to access the cloud, which provides its applications.

Ethernet Ethernet is a wired data network technology for local data networks (LANs). It allows data exchange between all devices connected to a local network (computer, printer, etc.). In its traditional form the LAN covers only over one building. Ethernet technology today also connects devices over long distances.
Landline A landline is the conventional telephone line, located at the end of a subscriber line (TAL). The landline are cable-connected data lines with the associated processing devices for transmitting data for data and voice.
Flatrate A usage-independent billing of telecommunication services – in particular in the sector of telephony and the Internet – with a e.g. monthly fee, depending on contractually agreed services (e.g., transfer bandwidth, data volume). Exceeding the agreed “service quantity” extra costs will come up.
Gigabit A gigabit is an information unit or unit for memory.
Fibre optic cable Communication medium made of high-purity quartz glass. Fiber optic cables have a higher transmission capacity (in the Gbit / s range) and lower signal distortions than copper cables.
GPRS General Packet Radio Service is a data transmission technology for mobile network , e.g. for transferring Internet pages to mobile phones. Billing is usually covered via the data volume.
GPS GPS is the abbreviation for “Global Positioning System”, a radio positioning method for position determination.
GSM The Global System for mobile communications is a standard for all-digital mobile networks that is used mainly for telephony but also for circuit-switched and packet-switched data transmission as well as short messages. It is the world’s most widely used mobile communication standard.
HotSpot HotSpots are locations, where users have access to fast internet via WLAN.
HSDPA High Speed Downlink Packet Access. Mobile technology, which increases the transmission rate in the UMTS network. This further development of UMTS allows data transmission in the downlink with a realistic data rate of up to 14.4 Mbit/s.
Intranet Intranet is a network which is based on the same techniques as the internet (TCP / IP, HTTP), but can only be used by a defined group of members of an organization. Companies pursue the aim of securing the supply of information for the employees.
IP The internet protocol is a network protocol. Through using IP addresses used in the IP network, computers can be grouped in a network and directly addressed. The versions IPv4 and IPv6t are defined. On this basis, almost all data networks have been operating since the end of the last century. The global Internet is also based on this protocol.
IP telephony Internet telephony or IP telephony (Internet Protocol telephony, also Voice over IP (VoIP)) is telephoning via computer networks which have the structures according to Internet standards.
iOS iOS is the Apple operating system for iPhone, iPod touch, iPad and the second generation of the Apple TV.
ISDN ISDN (Integrated Services Digital Network) ist a standard for a digital communications network.
IT Information technology (IT) is a general term for the information- and data processing as well as the hard- and software required for it.
LAN The Local Area Network is a local data network consisting of cabling and wired and wireless (W-LAN = wireless LAN) access components.
LTE Long Term Evolution. Mobile communications standard of the fourth generation and further development of UMTS. LTE is based on the transmission method, which also uses digital broadcasting, for example, and allows data transmission rates of more than 100 Mbit/s in the downlink.
M2M Machine-to-Machine, short M2M, is the automated interchange of information between terminals, such as machines, automats, vehicles or containers, or with a central control center.
Mobile payment Payment process where at least the person, who is liable to pay, requires to initiate electronic techniques to authorize or realize the payment.
Prepaid Prepaid means you pay in advance for a service. By purchasing a prepaid card for mobile phones you charge your credit on the mobile phone and being able use it later for phone calls, SMS and other services.
Postpaid Postpaid is the technical term for a mobile phone contract with accounting a following consumption by the provider. In contrast to a prepaid card, the postpaid mobile contract usually includes a fixed minimum contract term (often 24 months), a basic charge and / or a monthly minimum turnover. When a postpaid contract is concluded, it is customary for the customer to receive a most favorable mobile phone for the long-term commitment.
Roaming Roaming is the usage of a communication terminal, or only the usage of the subscriber identity in another visited network as the home network. This requires that the operators of two networks have a roaming agreement, as well as the necessary signaling and data connections between their networks. Roaming is an important element in the cross-national use of mobile phones.
Router A router has the function of connecting two spatially separated networks. The Internet on your computer can be used by the router.
SIM card The SIM card (Subscriber Identity Module) is a chip fom a mobile provider,  inserted into the mobile phone and enables to have access to the mobile connection.
Smartphone Smartphone is a mobile phone that provides more computer functionality and connectivity than a traditional mobile phone.
TCP/IP Transmission Control Protocol over Internet Protocol. The TCP/IP reference model describes the structure and the interaction of the network protocols from the Internet protocol family.
UMTS Universal Mobile Telecommunications System is a 3rd generation (3G) mobile phone standard. UMTS has an expanded range of services and replaced mobile communication via GSM. UMTS supports powerful multi-media services. In addition to voice and audio services, it includes fast data, graphics and text transmission, as well as the transmission of motion pictures and video.
Voice over IP (VoIP) VoIP is the combination of voice and data on a common infrastructure (TCP / IP protocol). It is the telephone communication via computer networks; data networks which operate with the widespread Internet protocol (IP). The VoIP technology uses the existing line resources much more efficiently and thereby reduces the call costs. In addition, IT applications and telephony are able to improve the cooperation due to shared network infrastructure.
VPN Virtual Private Network: a closed network that is built on a public network infrastructure. Only communication partners belonging to this private network can communicate with each other and exchange information and data. For example, VPNs are used by multi-site companies to secure data traffic between sites.
W-LAN Wireless Local Area Network is a radio standard for wireless data transmission in a small-scale local wireless network. To a W-LAN belongs, on the one hand, an access point, the W-LAN-Router, which connects to the Internet. On the other hand, a W-LAN-capable device, for example a laptop with a W-LAN adapter, is required.
