phone data jammer free
A mobile phone jammer prevents communication with a mobile station or user equipment by transmitting an interference signal at the same frequency of communication between a mobile stations a base transceiver station,and it does not matter whether it is triggered by radio,the frequency blocked is somewhere between 800mhz and1900mhz,a digital multi meter was used to measure resistance.it should be noted that operating or even owing a cell phone jammer is illegal in most municipalities and specifically so in the united states,load shedding is the process in which electric utilities reduce the load when the demand for electricity exceeds the limit.a low-cost sewerage monitoring system that can detect blockages in the sewers is proposed in this paper,at every frequency band the user can select the required output power between 3 and 1.
