How is The difference between ordinary and good quality mobile phone signal jammer
Mobile phone signal jammer
Signal jammer in general, can be classified into ordinary shielding and high quality shielding.
Ordinary mobile phone jammer： its technical characteristics are mainly based on the principle of shielding, using a large number of low-power or high-power equipment for confrontation, stay in a simple technical scheme.
High-quality mobile phone jammer： the technical characteristics of strong signal digital frequency hopping technology, compared with ordinary shielding technology, radiation reduction 150 times; mainly outdoor shielding, reduce indoor radiation power hundreds of times; using multi-channel combined technology, full-frequency antenna instead of N frequency divider antenna, suitable for wireless remote, lay the foundation for the use of distributed antenna; Antenna technology, reasonable distribution of shielding power, decentralized power signals, reduce antenna radiation, provide efficiency tens of times, while eliminating dead angle and leakage; Unique TD synchronization technology, China Mobile 3G (TD-SCDMA) and 4G (TD-LTE) network, shielding only downlink pilot slot, eliminate absolute interference to the base station. It has been approved by the mobile and Radio Regulatory Commission, and reduced radiation by dozens of times.
