An important part of any mobile phone specification is its operating frequency band. The band supported determines whether a particular phone is compatible with a particular network operator. When buying a mobile phone shield in the USA, you must know the cell phone jammer used in Germany.
First introduced in 1992, 2G was the second generation of mobile phone technology and the first to use digital encryption for calls. 2G networks were the first to offer data services and SMS text messaging, but their data transfer rates were lower than those of their successors.
Like almost all European countries, Germany uses the GSM band as its main frequency for telephone communications. The two cellular networks are D-Netz and E-Netz, which consist of the D1 and D2 standards for D-Netz E2 and the e-plus standard for E-Netz. The D-Netz network operates in the GSM900 band, while E-Netz operates in the GSM1800 band.
3G in Germany is represented by the 2100 MHz UMTS band, gradually joined by the 900 MHz band.
4G is the fourth generation of the cellular communication standard. It is the successor to 3G and provides ultra-broadband Internet access for mobile devices. The high data rates make 4G networks suitable for USB wireless modems for laptops and even for home internet access.
4G LTE in Germany mainly operates in the 800MHz frequency range, but other frequencies will be added later, including LTE 1800MHz, LTE 2600MHz.
GPS jammers can cause random loss of GPS data. In most cases, it does not happen at a specific time on a specific day of the pattern. Employees use Signal Jammer to do what they need to do to organise their company time, such as having lunch with friends, doing business, picking up the kids from school or getting home early. The fact that most of these actions are random could be a clue. Another clue is to see similar GPS tracking behaviour across business units and industries. Because drivers provide a ‘bouncing system’, others will mimic the behaviour you will see over time, increasing the random loss of GPS data between vehicles. Perhaps the best indication of mobile stuttering is through analysis of engine diagnostic data.
