Germany mobile phones, most of them use the same standard cell phone jammer communication to work. Although the standard in the communications system uses US telecommunications a little complicated, but the German cellular organization is more complex. As in almost all European countries, only with Germany the GSM frequency band as the primary telephone communication frequency. In Germany there are four GSM standards, i.e. D1, D2, E2 and E-Plus.
There are currently two large German mobile network companies and four large telecommunications companies:
The digital cellular network of the two companies (Germany, Deutsche Telekom all, uses GSM900 and GSM1800 bands, D1 standard) and Vodafone D2 (in Great Britain, use the GSM900 and GSM1800 frequency range, D2 standard)). D1 and D2 German cellular standard in GSM900 band, so T-Mobile and Vodafone not only use D network, also use the E network.
The digital cellular network started to work in 1994, which enables the use of low power telephones. The network used by the E-Plus Mobifunk (GSM1800 band, E2 and E-plus standard). As for the fourth paragraph mobile operators – Germany O2 (Telefonica Spanish all) – they also use GSM1800 frequency range, which also comply with this standard. So the network is used by all major German mobile phone companies.
The frequency range is provided by the four German mobile phone companies. Auction 3G spectrum in early 2000, Germany now the country has 3G access. 2100MHz 3G frequency band is used, although the German mobile phone companies will gradually integrate 3G services to 900 MHz band.
The Federal Network Agency for the LTE Spectrum Spectrum Communication 4G auction started in 2010. T-Mobile, Vodafone, O2 and E-Plus are very keen to purchase some of these bands to create their own 4G LTE service for the German people. 4G LTE access in Germany and sold in primary frequency usage is 800MHz, although the future will add other frequency ranges.
The main spectrum of the German GSM mobile phone is. Both of their main mobile communications networks are D-Netz and E-Netz, D1 and D2 are the standard E-Netz and the E-Plus-Standard D-Netz composition. D network GSM900 frequency bands of work, and E network GSM1800 frequency range is used for work.
Germany’s four major telecom operators and mobile operators are: Germany, T-Mobile, Vodafone D2, O2 Germany and E-Plus Mobifunk. All with GSM, 3G and 4G band offers different types of radio communication for the German people. Germany represented by the 3G band 2100MHz UMTS, and gradually added to the 900 MHz band. German 4G LTE especially in the 800 MHz frequency range. Of course, it can buy the relevant frequency interference.
