Cell Phone Jammers


Cell Phone Jammers


The usage of cell phones has increased massively; at present, peace and security is the need of the hour in several places. This can be achieved by utilizing a cell phone jammer, that blocks all the signals. One of the rising threats to security is unlawful cellular phone conversations at confidential places like court houses, military facilities, prisons etc. In fact, communication jamming devices were first developed and used by military forces to prevent successful transfer of information between enemy forces.

Knowing the difference: Traditional VS. Intelligent Cell Phone Jammers

There are two major types of jammers, non-intelligent i.e. traditional jammers, and intelligent jammers. The traditional jammer is utilized in a restricted area and is designed to block all cell phones that operate in a certain frequency band such as downlink frequency band of global system for mobile communication. This type of jammer is not fit for civilian use and especially for military applications, because it blocks all cell phones present in the restricted area. Moreover, the system will transmit jamming signals, whether there is an authorized mobile user in that restricted area or not.

On the flip side, the Intelligent jammers work as a detector and blocker which solves the pitfalls present in the traditional jammer. The system has the capability of creating a white list of authorized subscribers and allowing them to communicate freely while blocking all other phones in that area.

Stratign’s Intelligent Cell Phone Jammer (STN-ICJ3000) & its Beneficial Usage

The excusive technology used in this jammer permits the operator to specifically block communications of the unauthorized users inside its coverage range while allowing the authorized phones to operate.

Technology: How it works!

The STN-ICJ3000 provides the operator with absolute control over GSM phones functioning within the premises. Stratign’s highly advanced system is capable of automatically scanning and detecting all active 2G, 3G & 4G mobile phones within its coverage area. At the time of scanning, the system automatically gathers the handsets / SIM identities (such as TMSI, IMEI and IMSI) which can be utilized to recognize legal and illegal phones. By adding the authorized GSM phones to a GUI based ‘white-list’, the operator can allow them to communicate and the unauthorized mobile phones will be involuntarily jammed and would be added to the ‘black-list’.

What’s more, to locate unauthorized phones within the premises, the system can be integrated with a direction finder as well. Hence, numerous systems can be implemented and coordinated by a common GUI.

Valuable features:

• System capability: Selective Jamming of 2G, 3G and 4G Phones.
• Unlimited phones can be added to the white list.
• Flexible system & multiple systems can be integrated to cover larger areas/new networks.
• Displays the IMEI, MCC, MNC, IMSI, TMST type and model of all phones under the coverage range.
• All the examined parameters can be saved in a database for future analysis.
• Integration of direction finder: to physically locate & capture hidden cell phones.
• Both directional and omnidirectional antennas can be utilized to expand the coverage scope of the system.
• Can be remotely controlled using LAN or WAN
• Can display the approximate target location on digital map.

In conclusion, Stratign’s precise and effective Intelligent Cell Phone Jammer (STN-ICJ3000) enables to overcome various challenges of Law Enforcement Agencies worldwide.
