Professional and Useful Knowledges about Signal Jammer

A Phone Blocker is a communications jamming equipment that blocks signal transmission between cell base stations and mobile phones. And it works by sending the same radio frequencies to the Cell tower and blocking the receive and transmit frequency bands from the cell, including signals such as 5G, 4G, 3G, GSM and CDMA...

In layman's terms, signal jamming tools work by simulating the frequency of electronic communication devices (such as mobile phones, Wifi routers, GPS Tracker，etc.) and transmitting the frequency that are same with electronic devices, preventing electronic devices from transmitting and receiving mobile phone, Wifi, GPS or radio signals.

In addition, Portable frequency jammer and Powerful Desktop Blocking Device are easy to operate. Just after installing the antenna, turn on the power, the phone blocker can work normally and interfere with the network signal within its effective range.

You can of course use foil wallpaper to keep Wi-Fi out of the room. But if you knew about the existence of Wi-Fi jammers, you would definitely not use this ancient and troublesome operation. Just a Cheap Signal Blockers can completely block the wifi signal in the room, keep you safe from hacker attacks, wireless camera peeping and eavesdropping, keep your privacy and data protected.

Of course, but first you need to know how many ways electronic devices can be located and tracked. The most common ones are definitely GPS signal positioning and mobile phone number positioning, and the other is Lojack signal positioning (often used for Car recovery).

1. Mobile phone number positioning (also called base station positioning): The base station operator uses the cell phone signal of the mobile phone number to locate the mobile phone. Under normal circumstances, the user of the cell phone number must authorize the operator to locate the mobile phone through the base station; if not, only the public security department of the government can legally use it, and the authorization procedure is strictly stipulated, and the public cannot use it at all.

2. GPS signal positioning. Simply put, it is based on satellite GPS signal positioning. If you want to Jam the base station positioning signal at the same time, you also need to block the GSM, 3G, 4G, and 5G signals of the mobile phone.

3. Lojack signal location. The technology relies on short-range radio broadcasts, by emitting a set radio frequency, within a range of about 3-5 miles, through a receiver looking for the source of the transmission to locate it.

We have developed a powerful multifunctional Cell phone GPS Signal Scrambler device that can block all location tracking signals (including all GPS and satellite signals, all cell phone signals and Lojack radio signals), making all tracking devices useless.

Because the maximum distance of the signal jamer is tested by the product in an ideal test environment, in reality, many factors will affect the actual jamming distance of the signal scrambler, such as obstacles (concrete), high-power electronic products, surrounding magnetic field strength, battery power,...

Therefore, when choosing a electronic jammer, the overall performance of the Desktop Blocking Equipments (with more stable performance) are better than that of the Portable frequency disruptor at the same power condition; the overall performance of high-power jammer is better than that of the low-power jammer at the same type condition;

Rest assured, the strength of the electromagnetic signal emitted by the signal blockers is very weak. The test data shows that the network jammer not only will not cause any damage to the mobile phone or other electronic equipment, but the signal strength is also completely harmless to the human body. Its working principle is to block the uplink signal of the mobile phone or communication equipment, weaken or cancel the signal between the communication equipment to play the role of signal interference.

Generally speaking, only the electronic jammer device can make the illegal surveillance camera lose its function, but the premise is that this surveillance camera uses a wireless signal monitoring device, and the wireless signal jammer can make the illegal wireless camera useless by jamming the wireless signal. However, it has no effect on the conventional illegal buried wire monitoring equipment. The illegal buried wire monitoring equipment can only lose its function by removing the network cable or powering off..
