High-frequency electromagnetic fields

The frequencies of high-frequency electromagnetic fields range from 100 kilohertz to 300 gigahertz. In everyday life they occur primarily during wireless information transmission for radio, television, mobile communications and other communication technologies.

Home gateway

When connecting multiple devices in a customer's home to the Internet, it does not make sense to connect each device separately. A home gateway, such as a DSL router, is used instead. The gateway assigns specific services to each device and/or enables access to these devices, connecting the local area network (LAN) to a larger network.


Hospitality  denotes the relationship between guest and host. In compliance management, hospitality is subject to strict regulations governing the acceptance of gifts and benefits that have a monetary value.


HotSpot  is the name of a public area where customers can access the Internet using wireless local area networks ( WLAN). The HotSpots are realized jointly by T-Home and T-Mobile.

HSDPA (High Speed Downlink Packet Access)

Packet-based protocol that enhances data rates in UMTS networks and lifts transmission speeds into the megabit range.

HSE (health, safety and environmental management system)

HSE denotes comprehensive health, safety and environmental management systems. Based on various management standards such as ISO 14001  (environmental management) and OHSAS 18001  (occupational safety and health), HSE provides tools for continually improving a company's performance.

HSUPA (High Speed Uplink Packet Access)

HSUPA 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.
