GSM channel jamming can only be successful if the GSM signal strength is weak. For communication with security system devices hub uses Jeweller radio technology.
#Wireless signal jammer plus
Hub uses GSM and Ethernet for connection to Ajax Cloud service and for the transmission of alarms to the user and the security company, and Hub 2 Plus is unique among the security system control panels - it uses four authorized communication channels at the same time: Wi-Fi, Ethernet, and two 2G/3G/LTE SIM-card slots. How the Ajax security system responds to jamming In order to increase the jamming coverage, expensive broadband amplifiers are required, and the creation of such equipment involves specialized skills. Self-made - as a rule, low-power jammers that operate over short distances.All this affects the dimensions of the device, and jammers with a range of 100 meters (in open space) have considerable dimensions, need forced cooling, and power supply of 230 V.

Also, the lower the jamming frequency, the larger the size of the interference generator antenna must be. Powerful jammers can become very hot, and they require additional cooling. The wider the frequency band and the larger the jamming radius, the more powerful the interference generator must be.

The higher the price, the greater the range and number of networks that they can jam. Stationary- such appliances are much more powerful and expensive.
#Wireless signal jammer portable
Hand-held or portable with the size of a phone and relatively low power therefore, they prevent data transmission at a distance of 5-15 meters (without obstacles).Jeweller radio communication (868.0–868.6 MHz or 868.7–869.2 MHz depending on the region)īroadband interference generators that can jam several networks at once (for example, Wi-Fi and GSM) can be:.2G/GSM (900/1800 MHz), 3G/UMTS (2100 MHz), and LTE (900/1800/2600 МHz depending on the region of sale) networks of cellular operators.Interference generator can “jam” a certain band or be broadband sabotaging several communication technologies of security systems simultaneously.įor example, Ajax uses 5 frequency bands for communication: Sergey Yuriev, a technical expert of the Carabiner security company What types of jammers exist Jamming is inexpedient in this case as it only delays the process. This is attributed to the fact that home burglaries at the premises equipped with alarm systems last under 2 minutes. not more than 5 cases per year per 20,000 protected facilities. Jamming attempts occur relatively rarely, i. Jamming can be aimed at both individual detectors and the security system as a whole. If the frequencies of the device and the jammer do not match, the jamming will not affect the operation of the device. Interference generators operate within a specific radius at the frequency of the device whose operation is to be disturbed. Devices for jamming are called interference generators or signal suppressors and they are commonly known as jammers.

It is used to prevent communication of alarms within wireless security systems. Jamming represents unlawful creation of interference within radio channels. This article dispels the myths about jammers, talks about their real capabilities, and how counteraction is implemented in Ajax for this type of sabotage. Consequently, the facility becomes defenseless. It can presumably be easily jammed using equipment that can be purchased “at every corner,” and without radio communication, the alarm system is deprived of the opportunity to resist the intruders. Radio communication is regarded as the main vulnerability of wireless security systems.
