The emergence of wireless communication has greatly changed the reality of our lives. Cellular signals are only unavailable in the most remote areas. In many cases, the benefits are undeniable, but there are always downsides. Intense business competition usually means obtaining information in any way, including unauthorized access to confidential data through illegal means. Therefore, it is not surprising that business information leaks due to emails being hacked or tapped in conversations. Car security systems, alarms, courier services-all thanks to the support of GPS and GSM standards. But sometimes people need a little privacy, and then they may need signal jammer.
Manufacturers provide fixed and portable jammers
Let's take a closer look at one of them-EaglePro Blizzard. This device model not only covers the radio frequency of GSM cellular communication, but also covers CDMA, DCS, GPS and Wi-Fi signals.
Battery jammers are most commonly used for:
Ensure the security of information during the meeting;
Disable the tracking system for a period of time;
The mobile communication is temporarily disconnected due to personal reasons;
Vehicle camouflage (related to the driver).
In the Russian Federation, the law does not prohibit the distribution of cell and GPS jammer, but these devices can only be used after registration with Roskomnadzor.
Regardless of the power, devices follow a general principle: they generate noise fields in the same frequency range as the device to be suppressed. The signal is invalid for reception or return. Regardless of whether there is a working device in the range, the jammer will always cause interference.
Full set of functions
Jammer EaglePro Blizzard is a lightweight and compact portable device. The range of action is 5 to 10 meters. Suppress GSM cellular signal and 3G Internet. Using the NetMonitor program, we tested the operation of the suppressor on the GSM signal levels of four major mobile operators in Russia. The research results show that the device can fully cope with and perfectly suppress the signal in all situations.
The manufacturer has equipped the device with two power adapters so that it can run continuously through a 220 V network or car charging.
A fully charged battery can last for 90 minutes
