Using Mobile Phone Signal Jammer Need Permission In Germany

Mobile Phone Jammer Device Related Laws Of Germany

　　Germany has strict legal regulations on the use of 4g 5g mobile phone signal jammer devices (also known as 3g 4g signal jammers, cell phone blockers). Under Germany's Telecommunications Act (Telekommunikationsgesetz, TKG), unauthorized signal jammer devices are illegal in most cases.

1. Illegal use: Under the German Telecommunications Act, it is illegal for any person or organization to use a signal jammer devce in Germany without the approval of the Federal Network Agency (Bundesnetzagentur, BNetzA). Illegal use of these devices may result in serious legal consequences, including fines and criminal penalties.
2. Permit requirements: In rare special cases, certain institutions (such as government departments, the military or law enforcement agencies) may obtain permission to use signal jammers. These permissions are usually granted in specific scenarios (such as protecting sensitive facilities, conducting special operations, etc.).

Germany's mobile communications network is operated by several major operators, namely:

　　Deutsche Telekom (Telekom)

　　Frequency bands:

• 2G (GSM): 900 MHz, 1800 MHz
• 3G (UMTS): 2100 MHz
• 4G (LTE): 800 MHz, 900 MHz, 1800 MHz, 2100 MHz, 2600 MHz
• 5G: 700 MHz, 2100 MHz, 3600 MHz

　　Vodafone Germany

• Frequency bands:
• 2G (GSM): 900 MHz, 1800 MHz
• 3G (UMTS): 2100 MHz

2. 800 MHz: Similar to 700 MHz, with good coverage and penetration.
3. 900 MHz: Usually used for 2G networks, but also gradually used for 4G expansion.
4. 1800 MHz: More commonly used in cities and suburbs, suitable for medium coverage and capacity.
5. 2100 MHz: originally used for 3G networks, now also used for 4G and 5G network expansion.
6. 2600 MHz: high frequency band, suitable for high data traffic demand in urban areas.
7. 3600 MHz: mainly used for 5G networks, providing higher bandwidth and speed, suitable for dense urban environments.
