How to choose a cell phone signal jammer? from YIFALIU's blog

There are all kinds of cell phone jammer and all kinds of machines on the market. Prices are also unstable. Maybe you've bought a cheap machine on a platform, but it actually didn't work. When buying mobile phone signal shielding, you can't care about the price, because buyers are useful. Otherwise, even if a useless machine is cheap, consumers will have no actual effect. When choosing mobile phone signal shielding, you know what aspects you need to use. You can tell our company's expert who specializes in selling mobile phone signal shielding and he will introduce it to you one by one. Recommend suitable styles to you so that you won’t step into any 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 equipment to fight, and staying in a simple technical solution.

Ordinary mobile phone signal shields are nowhere near as expensive, quality, or efficient as high-quality mobile phone signal shields because their cost is there too. Especially temperature control. Ordinary mobile phone signal shielding basically does not have temperature control technology. Under poor heat dissipation conditions, ordinary mobile phone signal shielding will not automatically reduce the power to maintain, causing the machine to crash or spontaneously ignite. Therefore, ordinary mobile phone signal transmitters are really not recommended for everyone to use. Even the price is cheap. It is also not recommended for use by consumers.

2. High-quality mobile phone signal shielding.

The technical characteristics of high-quality mobile phone signal shielding are the use of strong signal digital point frequency hopping technology, which is 150 times lower than ordinary shielding technology; mainly outdoor shielding, which reduces indoor radiation power by hundreds of times; the use of multi-channel combining technology, all-round The frequency antenna replaces N frequency division antennas and is suitable for distributed antennas of wireless antennas; it uses distributed antenna technology to reasonably distribute shielding power and reduce antenna radiation by dozens of times; it uses 4G network and multi-channel combining technology to effectively reduce the number of antenna radiation ten times.

Ordinary mobile phone signal shields are nowhere near as expensive, quality, or efficient as high-quality signal jammers because their cost is there too. Especially temperature control. Ordinary mobile phone signal shielding basically does not have temperature control technology. Under poor heat dissipation conditions, ordinary mobile phone signal shielding will not automatically reduce the power to maintain, causing the machine to crash or spontaneously ignite. Therefore, ordinary mobile phone signal transmitters are really not recommended for everyone to use. Even the price is cheap. It is also not recommended for use by consumers.

High-quality mobile phone signal shielding is far superior in quality to ordinary mobile phone signal shielding. At the end of the day, the parts are installed using quality chips. And can work for a long time in harsh environments. The temperature control is also very stable. When the machine reaches a certain temperature, the Jinyuda mobile phone signal screen will turn on. It can automatically reduce the power to ensure that the machine will not burn out and at the same time ensure the operation of the machine. Moreover, high-quality mobile phone signal shielding uses gain antennas whether it is a built-in antenna or an external antenna. Coverage has also been greatly improved.
