The narrow band internet connection category includes dial-up connections via an analogue telephone line or an ISDN connection. The most common broadband technology used in Germany, for instance, is DSL. It uses the existing two-wire copper telephone lines and makes these available for high bandwidths. Other technologies based on fixed line connections are internet connections via cable TV or via optical connections such as fibre optics. In addition to these technologies, a broadband internet connection can also be implemented on a wireless basis. These use mobile networks, satellites or other wireless technologies such as WLAN and WiMAX.
A broadband internet connection is a key location factor for both private users and companies. Politicians therefore strive for a widespread availability of broadband internet. After all, providing a high speed internet connection is especially difficult in rural areas, requiring major investments from internet suppliers. The government therefore supports the expansion in underserved areas with public funds. Wireless technologies such as LTE are often used in these areas as they do not require costly running of cables.
