| 3G | 3G is the third-generation mobile communications standard that supports higher transmission rates. In Germany, this is the Universal Mobile Telecommunications System (UMTS) standard. |
| 4 | |
| 4G | This is what the industry calls the fourth-generation mobile communications standard (see LTE). |
| A | |
| Access | Internet access. |
| ADSL | See DSL. |
| ADSL+ | See DSL. |
| All-IP | An all-IP network makes services such as VoIP, IPTV (Internet Protocol Television), data transfer, etc., available to all users anywhere at all times. The data is transmitted in switched packets using the Internet Protocol (IP). |
| Android Market | Android Market is a platform for mobile devices and is based largely on Linux and Java. The platform is being developed by the Open Handset Alliance, a Google initiative that counts T-Mobile among its members. In October 2008, T-Mobile launched the first cell phone in the United States to use this platform – the T-Mobile G1 – on the market. (Launch in the United Kingdom in November 2008, in Germany in February 2009). |
| APM (Application Performance Management) | Managed service designed to optimize corporate networks. T-Systems’ APM solution portfolio uses three modules to ensure that customers can keep track of and optimize their entire ICT infrastructures, from the servers right through to users. The consulting package offers a comprehensive analysis of the performance of a company’s applications and ICT infrastructure. The monitoring module allows faults and bottlenecks in the system to be identified at an early stage and eliminated as a result of targeted investment in the infrastructure. The optimization measures improve application response times by, for example, avoiding duplicated data transmission. This enables data transmission speeds within the network to be accelerated by a factor of up to 50. In addition, early fault diagnosis also helps to reduce operating costs. |
| App. | Short for application. Apps are application programs for smartphones in particular. They are usually available via an online shop that is directly integrated into the smartphone’s operating system and can be directly installed on the device. |
| ASP | Service that enables enterprises to lease IT applications. The advantage: Customers can always use the latest version that the provider maintains centrally (e.g., in a computer center) and do not have to worry about buying and maintaining software applications (licenses, updates) themselves. |

| Cloud computing | Cloud computing is the dynamic provision of infrastructure, software or platform services online. Apart from a high level of automation and virtualization, the services provided have to be multi-client-capable and include standardized hardware and software. Customers source these services on demand and pay based on actual usage. The communication infrastructure may be the Internet (public cloud), a corporate network (private cloud) or a mix of the two (hybrid cloud). Dynamic Services is a T-Systems product for the flexible procurement of ICT resources and services. |

ADSL2+: Successor product to ADSL that raises the maximum data rate to 16 Mbit/s (downstream) or 1 Mbit/s (upstream). VDSL (Very high bit rate Digital Subscriber Line) is a new technology used to transmit exceptionally high data rates (5 Mbit/s upstream, 50 Mbit/s downstream) via a fiber-optic network. |
| E | |
| Embedded system | Refers to an electronic calculator or computer embedded in a technical system where the calculator either controls and monitors the system it is embedded in or is used for processing specific data or signals, for instance in connection with encryption, decryption, encoding, and decoding of filters. Embedded systems perform dedicated functions – mostly unrecognized by users – in a variety of applications and devices such as medical equipment, washing machines, aircraft, automobiles, refrigerators, TVs, DVD players, set-top boxes, cell phones or other consumer electronics devices. When used in complex systems, a wide range of otherwise autonomous embedded systems are usually combined in a network (e.g., in a vehicle or aircraft). |
| Enabling | Enabling services are a key component of our business model. We enable other companies or software developers to integrate our network and IT abilities into their own services via standard interfaces. For this purpose we bundle our products to create a toolkit of standard services, supporting the growth of our business partners and benefiting ourselves at the same time. |

| HSUPA (High Speed Uplink Packet Access) | The technology accelerates data upstreaming from mobile devices into the network and significantly reduces transfer durations (ping time). This makes HSUPA the ideal complement to HSDPA on T-Mobile’s network. Together, HSDPA and HSUPA ensure that users can surf the Internet or work in the intranet while on the move, experiencing a similar level of user comfort as with fixed-network DSL. |

SMS, and MMS in particular, refer not only to the services, but also to the messages themselves. |
| Stakeholder | The stakeholder approach is an extension of the shareholder value approach widely used in business management. In contrast to the shareholder value principle, which focuses on the needs and expectations of a company’s shareholders, the stakeholder approach attempts to appreciate the company against its overall social background and reconcile the needs of the different stakeholders. In addition to shareholders, stakeholders include staff, customers, suppliers, the government, and the public at large. |
