Signal Detection and blocker Jamming
A method for detecting jamming, characterized in that it includes a detection stage and a confirmation stage; the detection stage includes the following steps: (1) start operation; (2) parameter initialization, setting a signal strength threshold; (3) signal strength Detect; (4) compare the amplitude of change with the set signal strength threshold, judge whether to exceed, if so, execute step (5), if not, execute step (3); Described detection stage comprises the following steps: ( 5) Delay and wait; (6) determine whether the base station information BSIC can be decoded, if so, return to step 0), if not, confirm that it is signal interference.
First of all, the receiver actively initiates scanning of each communication channel in the communication frequency band, and judges whether the value of the channel characteristics exceeds the limit value for the channel with higher signal power detected jamming signal.
Hand held signal shielding device is our factory using advanced technology, for the contiuous developmentof communication standards, according to the actual situation of domestic and international wireless ommunication to develop
World First 24 Antennas all-in-one design wireless signal Jammer with nylon cover for portable, jamming all types of Android phones, Tablets, Smart Phones, iPhones, Win phones etc. that use 2G, 3G, 4G 5G, and CDMA 450Mhz
The jammers are customized according to the frequency bands of different countries, please confirm that the purchase country and the actual use country are consistent. Otherwise it can not be used.Please read the jammer function before purchasin
