Signal shielding, generally speaking, can be divided into ordinary shielding and high-quality shielding.

The technical characteristics of ordinary shielding are mainly based on the shielding principle, using a large number of low-power or high-power equipment to fight against, and staying on a simple technical solution.

High-quality signal blocker, its technical characteristics use strong signal digital point frequency hopping technology, which reduces radiation by 150 times compared with ordinary shielding technology; mainly outdoor shielding, reducing indoor radiation power by hundreds of times; using multi-channel technology, full-frequency antenna Instead of N frequency division antennas, it is suitable for wireless remote and lays the foundation for distributed antennas; distributed antenna technology is used to reasonably distribute shielding power, disperse power signals, reduce antenna radiation, provide dozens of times efficiency, and eliminate dead spots and leakage. Point; topsignaljammer's unique synchronization technology, for China Mobile's 3G (TD-SCDMA) and 4G (TD-LTE) networks, only shields the downlink pilot frequency slot, eliminates the interference to the base station, and is approved by the Mobile and Radio Regulatory Commission. Recognition, while reducing radiation dozens of times.
