There are many kinds of cell phone jammers on the market, and there are also various machines. Prices also vary. Maybe you may have purchased a cheap machine on a certain platform, but it was useless in actual use. In fact, when buying a mobile phone signal jammer, you don't have to care about its price, because the main buyer must buy it if it is useful. Otherwise, even if the useless machine is cheap, it will have no practical effect for consumers to buy it. When choosing a mobile phone signal jammer, you only need to know what type of signal blocker you are going to use. We will recommend a suitable model to you so that you will not step into the trap.
Mobile phone signal blocking can generally be divided into two categories:
1. Ordinary mobile phone signal blocking
The technical characteristics of ordinary mobile phone signal shielding are mainly based on the shielding principle, using a large number of low-power or high-power devices to fight, and staying on simple technical solutions.
Ordinary cell phone jammers are far lower than high-quality mobile phone signal jammers in terms of price, quality, or work efficiency, because their parts cost is also low. Especially temperature control. Ordinary mobile phone signal jammers basically have no temperature control technology. Under poor heat dissipation, ordinary mobile phone signal jammers will not reduce the power to maintain their own problems, causing the machine to crash or spontaneously ignite. . Therefore, it is really not recommended for everyone to use ordinary mobile phone signal transmitters. Even the price is favorable. It is not recommended for consumers to use
2. Shielded by high-quality mobile phone signal jammer.
The technical characteristics of high-quality mobile phone signal jammers are the use of strong signal digital point frequency hopping technology, which reduces radiation 150 times compared to ordinary shielding technology; it is mainly based on outdoor shielding, reducing indoor radiation power hundreds of times; it adopts multi-channel combining technology, The full-frequency antenna replaces N divided-frequency antennas, which is suitable for wireless remote control and lays the foundation for distributed antennas.
It adopts distributed antenna technology to reasonably allocate shielding power, disperse the power signal, reduce antenna radiation, provide dozens of times of efficiency, and at the same time eliminate Dead spots and leakage points; Jike's unique TD synchronization technology only blocks the downlink pilot time slots for China Mobile's 3G (TD-SCDMA) and 4G (TD-LTE) networks, shielding the signal source, and obtaining mobile and Approved by the Radio Regulatory Commission while reducing radiation dozens of times.
