German cell phones, or what they call them – the cell phone (the cell phones, if there are many) use only a few different cell phone standards for their work. In the United States, there are few incompatible telecommunications standards for communication systems, while Germany has a much more differentiated approach to organizing mobile phone communication. As in almost all European countries, Germany uses GSM frequency bands as the main frequency for mobile phones. In Germany there are four main GSM standards that compete with each other – D1, D2, E2 and E-Plus.
There are currently two large mobile radio networks and four telecommunications companies in Germany that use them:
D network
This digital cellular network is used by two companies – T-Mobile Deutschland (owned by Deutschland Telekom, uses the frequency bands GSM900 and GSM1800, standard D1) and Vodafone D2 (British company, frequency bands GSM900 and GSM1800, standard D2)). D1 and D2 German mobile radio standards are in the GSM900 band. T-Mobile and Vodafone therefore use not only the D network, but also the E network.
E network
This digital cellular network was founded in 1994 and enables cell phones to use a low wattage for their work. This network is used by E-Plus Mobifunk (GSM1800 frequency band, E2 and E-Plus standards). As the fourth mobile operator – O2 Germany (owned by the Spanish Telefonica) – they also use the GSM1800 frequency range and therefore also work in this standard. This network is therefore used by all major mobile phone companies in Germany.
3G UMTS
These frequency ranges are offered by all four large German mobile phone companies. 3G frequency bands were auctioned at the beginning of the 2000s, and Germany now has wide 3G access across the country. The 2100 MHz frequency band is used as the main 3G band. However, German mobile operators are gradually integrating 3G services into the 900 MHz frequency range.
4G LTE
In 2010, the Federal Network Agency auctioned off the LTE spectrum for 4G communication frequencies. T-Mobile, Vodafone, O2 and E-Plus were very interested in purchasing parts of these bands to create their own 4G jammer LTE services for Germans. The main frequency spectrum that was sold in Germany and is used for 4G LTE access is 800 MHz. However, it is possible that more frequency ranges will be added in the future.
ultimately
The main frequency spectrum for mobile phones in Germany is GSM. Their two main communication networks for mobile phones are D-Netz and E-Netz, which consist of D1 and D2 standards from D-Netz and E2 with E-Plus standards from E-Netz. The D-Netz network uses the GSM900 frequency band for its work, while the E-Netz uses the GSM1800 frequency band for its work.
There are 4 major German telecommunications operators and mobile operators: T-Mobile Germany, Vodafone D2, O2 Germany and E-Plus Mobifunk. All use the GSM, 3G and 4G frequency band to provide German people with different types of wireless communication. German 3G is represented by the 2100 MHz UMTS band and is gradually being added to the 900 MHz band. In Germany, 4G LTE mainly works in the 800 MHz frequency range, but other frequencies can be added later.
