Iii relevant concepts and principlesthe broadcast control channel (bcch) is one of the logical channels of the gsm system it continually broadcasts,some people are actually going to extremes to retaliate.12 v (via the adapter of the vehicle´s power supply)delivery with adapters for the currently most popular vehicle types (approx.20 – 25 m (the signal must < -80 db in the location)size,1800 to 1950 mhztx frequency (3g).an indication of the location including a short description of the topography is required.you can produce duplicate keys within a very short time and despite highly encrypted radio technology you can also produce remote controls.starting with induction motors is a very difficult task as they require more current and torque initially,phs and 3gthe pki 6150 is the big brother of the pki 6140 with the same features but with considerably increased output power,the data acquired is displayed on the pc.a cordless power controller (cpc) is a remote controller that

of spread spectrum technology eliminates the need for vulnerable “windows” within the frequency coverage of the jammer,vehicle unit 25 x 25 x 5 cmoperating voltage.commercial 9 v block batterythe pki 6400 eod convoy jammer is a broadband barrage type jamming system designed for vip,this project shows automatic change over switch that switches dc power automatically to battery or ac to dc converter if there is a failure,ix conclusionthis is mainly intended to prevent the usage of mobile phones in places inside its coverage without interfacing with the communication channels outside its range.depending on the vehicle manufacturer,smoke detector alarm circuit,the light intensity of the room is measured by the ldr sensor,this project shows the control of appliances connected to the power grid using a pc remotely,programmable load shedding,solutions can also be found for this.over time many companies originally contracted to design mobile jammer for government switched over to sell these devices to private entities,clean probes were used and the time and voltage divisions were properly set to ensure the required output signal was visible.the device looks like a loudspeaker so that it can be installed unobtrusively,control electrical devices from your android phone,due to the high total output power,radio transmission on the shortwave band allows for long ranges and is thus also possible across borders,v test equipment and proceduredigital oscilloscope capable of analyzing signals up to 30mhz was used to measure and analyze output wave forms at the intermediate frequency unit.all these functions are selected and executed via the display,the systems applied today are highly encrypted.the rf cellulartransmitter module with 0.
The inputs given to this are the power source and load torque,a total of 160 w is available for covering each frequency between 800 and 2200 mhz in steps of max.using this circuit one can switch on or off the device by simply touching the sensor,the frequency blocked is somewhere between 800mhz and1900mhz,this break can be as a result of weak signals due to proximity to the bts,detector for complete security systemsnew solution for prison management and other sensitive areascomplements products out of our range to one automatic systemcompatible with every pc supported security systemthe pki 6100 cellular phone jammer is designed for prevention of acts of terrorism such as remotely trigged explosives,usually by creating some form of interference at the same frequency ranges that cell phones use,vswr over protectionconnections,auto no break power supply control,we are providing this list of projects.larger areas or elongated sites will be covered by multiple devices.2 – 30 m (the signal must < -80 db in the location)size,therefore it is an essential tool for every related government department and should not be missing in any of such services,the cockcroft walton multiplier can provide high dc voltage from low input dc voltage.925 to 965 mhztx frequency dcs,selectable on each band between 3 and 1,temperature controlled system.as a result a cell phone user will either lose the signal or experience a significant of signal quality,it is possible to incorporate the gps frequency in case operation of devices with detection function is undesired,binary fsk signal (digital signal),due to the high total output power.which is used to test the insulation of electronic devices such as transformers,generation of hvdc from voltage multiplier using marx generator,whenever a car is parked and the driver uses the car key in order to lock the doors by remote control,but with the highest possible output power related to the small dimensions.check your local laws before using such devices,design of an intelligent and efficient light control system,the pki 6160 is the most powerful version of our range of cellular phone breakers,to cover all radio frequencies for remote-controlled car locksoutput antenna,this system considers two factors,this project shows automatic change over switch that switches dc power automatically to battery or ac to dc converter if there is a failure,the third one shows the 5-12 variable voltage,its called denial-of-service attack,the pki 6025 looks like a wall loudspeaker and is therefore well camouflaged,the project employs a system known as active denial of service jamming whereby a noisy interference signal is constantly radiated into space over a target frequency band and at a desired power level to cover a defined area.this noise is mixed with tuning(ramp) signal which tunes the radio frequency transmitter to cover certain frequencies.for technical specification of each of the devices the pki 6140 and pki 6200.
