What are the small signal jammers?

What we generally call a small signal jammer refers to a signal jammer that acts in a small area, such as conference rooms, opera halls, and recording studios. it is good?

At present, the best small signal jammers on the market are signaling-level digital signal jammers, which have the following characteristics:

1. It will not interfere with the base station: the traditional shielding product has a very large impact on the operator's network, but this product adopts a new TDD shielding algorithm, which only interferes with the downlink of the TDD base station, not the TDD base station.

2. The signaling-level digital signal shielding device has low power transmission, and has a shielding advantage of 5 times compared with the traditional analog shielding technology.

3. Support the shielding of all mobile phone 2G-5G wireless communication frequency bands

4. Simple installation and operation, with self-adaptive function, plug and play, without parameter setting.

5. Timing function, can set the running time of each device.

6. Support the networking of all devices, network port connection, standard TCP/IP protocol, can remotely monitor the running status of the device in real time, and adjust the parameters of the device remotely.

In the shielded area, the small signal jammer can effectively block the mobile communication services of various operators, including voice, data, SMS and other services. Its various operators include China Mobile, China Telecom, and China Unicom. The network standard includes 2G, 3G, 4G, and 5G.
