The portable jammer sends the RF signal to the receiving area of ​​the phone

What do you know about spurious signals called “complaints”, wireless alarm systems or GSM connections (necessary to send alarms to ancillary services)? How much technical knowledge is required? Therefore, from the beginning: the destruction of the radio network is punishable: the distribution, possession and use of electrical equipment (GSM jammers) that prevent radio communication is prohibited. In view of the protection objectives of the “Federal Radio Systems and Telecommunications Terminal Equipment Act” (FTEG) of the Official Gazette II 134/2001 and the electromagnetic compatibility regulations of the Federal Register II 2006 issued on May 29, 2006, it is highly appreciated and sold to the Austrian market Jammer on the board. Likewise, the use of these devices is prohibited.

In addition to an administrative fine of up to 36,336 euros, the telecommunications authorities can also seize these devices. Disturbing in school: the principal emphasized how does it work technically? It’s actually very simple: the portable handheld jammer sends the RF signal to the receiving area of ​​the phone. The unfortunate situation is closer than that of the next tower, and it doesn’t even need a lot of energy to disturb the phone. Suffering? What does this mean for wireless alarm systems?

The internal communication between the system and components occurs at 434 MHz or 868 MHz (not to be confused with 802.11 WIFI 2.4 GHz). WIFI is useless, designed to carry a large amount of data, but is not suitable for penetrating solid materials (walls).

Many radio systems communicate in both directions, if there is no communication with each detector, the center will become like this, which may cause interference/damage, as well as in the emergency center (central phone). Of course, GSM/GPRS should only be the second communication method. This means that the control center must be wired for communication (such as TCP/IP cable/ADSL telephone line). Radio communication is easily interrupted. If it is a wireless alarm system, two-way alarm and wired keyboard connection, GSM/GPRS is only used as an auxiliary means. The super safe side is of course the wired alarm system.
