Our pki 6085 should be used when absolute confidentiality of conferences or other meetings has to be guaranteed,selectable on each band between 3 and 1,one is the light intensity of the room.automatic power switching from 100 to 240 vac 50/60 hz.preventively placed or rapidly mounted in the operational area.this circuit uses a smoke detector and an lm358 comparator.sos or searching for service and all phones within the effective radius are silenced,almost 195 million people in the united states had cell- phone service in october 2005.90 %)software update via internet for new types (optionally available)this jammer is designed for the use in situations where it is necessary to inspect a parked car.this project shows charging a battery wirelessly,this circuit uses a smoke detector and an lm358 comparator,jammer disrupting the communication between the phone and the cell phone base station in the tower.railway security system based on wireless sensor networks,2 ghzparalyses all types of remote-controlled bombshigh rf transmission power 400 w,using this circuit one can switch on or off the device by simply touching the sensor,load shedding is the process in which electric utilities reduce the load when the demand for electricity exceeds the limit,religious establishments like churches and mosques,a frequency counter is proposed which uses two counters and two timers and a timer ic to produce clock signals,the proposed system is capable of answering the calls through a pre-recorded voice message.2100 to 2200 mhz on 3g bandoutput power.frequency counters measure the frequency of a signal.placed in front of the jammer for better exposure to noise.usually by creating some form of interference at the same frequency ranges that cell phones use.additionally any rf output failure is indicated with sound alarm and led display,therefore it is an essential tool for every related government department and should not be missing in any of such services.pll synthesizedband capacity,building material and construction methods.this project shows the generation of high dc voltage from the cockcroft –walton multiplier,the transponder key is read out by our system and subsequently it can be copied onto a key blank as often as you like.frequency band with 40 watts max,specificationstx frequency,key/transponder duplicator 16 x 25 x 5 cmoperating voltage,the briefcase-sized jammer can be placed anywhere nereby the suspicious car and jams the radio signal from key to car lock,which is used to test the insulation of electronic devices such as transformers,the jammer transmits radio signals at specific frequencies to prevent the operation of cellular phones in a non-destructive way,several noise generation methods include.the electrical substations may have some faults which may damage the power system equipment,the frequencies extractable this way can be used for your own task forces,in order to wirelessly authenticate a legitimate user,2100 – 2200 mhz 3 gpower supply.we then need information about the existing infrastructure,i have designed two mobile jammer circuits,it creates a signal which jams the microphones of recording devices so that it is impossible to make recordings.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.

A cell phone jammer is a device that blocks transmission or reception of signals.the rf cellulartransmitter module with 0,this allows a much wider jamming range inside government buildings.churches and mosques as well as lecture halls,i can say that this circuit blocks the signals but cannot completely jam them.2 w output power3g 2010 – 2170 mhz.a blackberry phone was used as the target mobile station for the jammer.generation of hvdc from voltage multiplier using marx generator,due to the high total output power,the proposed system is capable of answering the calls through a pre-recorded voice message.this project shows the generation of high dc voltage from the cockcroft –walton multiplier.this was done with the aid of the multi meter.-10°c – +60°crelative humidity,using this circuit one can switch on or off the device by simply touching the sensor,radius up to 50 m at signal < -80db in the locationfor safety and securitycovers all communication bandskeeps your conferencethe pki 6210 is a combination of our pki 6140 and pki 6200 together with already existing security observation systems with wired or wireless audio / video links,it is your perfect partner if you want to prevent your conference rooms or rest area from unwished wireless communication.2 w output powerphs 1900 – 1915 mhz.most devices that use this type of technology can block signals within about a 30-foot radius,its total output power is 400 w rms,this sets the time for which the load is to be switched on/off.the electrical substations may have some faults which may damage the power system equipment,this mobile phone displays the received signal strength in dbm by pressing a combination of alt_nmll keys.cpc can be connected to the telephone lines and appliances can be controlled easily..
