MDPB-15XL signal blocker is based on the principle of mobile phone communication, combined with the actual situation of domestic mobile communication, based on SDR(software radio) architecture design and development, using signaling level interference strategy, from the signal physical layer definition, signal modulation mode and other technical characteristics of the target signal targeted and efficient interference shielding. It can effectively block 2G, 3G, 4G, 5G mobile phone signals and 2.4G, 5.2G, 5.8G (WiFi and Bluetooth) signals in a range of 1-30 meters (depending on the carrier environment). So that the mobile phone can not play and receive calls, can not send and receive short messages and use the network, and the related wireless communication equipment can not transmit signals, which is manifested as the search network, no signal, no service system and so on. However, it will not interfere with the work of other electronic devices, and the phone can be restored to normal use when it leaves the shielding range.

Based on SDR(software radio) architecture design and development, the signaling level interference strategy is adopted, and the technical characteristics such as signal physical layer definition and signal modulation mode are used to automatically detect and scan the communication frequency points and signal strength in the entire shield area, and equipment is configured to perform point-to-point efficient interference shielding for the communication key channels. Compared with traditional sweep compression, the energy efficiency can be improved by 10-100 times.

The transmission power is small, the interference efficiency is high, compared with the traditional shielding technology, in the case of the same transmission power has a good interference effect and coverage distance, and truly achieve low power full standard high efficiency shielding.

Accurately shield the downlink signal of the base station within the coverage range, only interfering with the mobile phone terminal, does not affect the uplink communication of the base station, especially suitable for the downlink signal shielding of the TDD system, does not affect and hinder the security of public communication.

It supports shielding interference in all mainstream communication bands in the 700MHz-6GHz range, covering 2G/3G/4G/5G mobile communications as well as WiFi and Bluetooth signals. Support independent configuration of channel power, can be set separately to a frequency band for separate shielding, truly achieve digital signal control.

The device is small in size, light in weight, simple to use, plug and play, due to a variety of equipment use scenarios, different scenarios will have different frequency bands, frequency points. The algorithm of the device supports adaptive function, which can automatically match any scene and any frequency band. After power-on, you can mask signals without parameter configuration and other additional operations.

Supports the one-key switch shielding function through the background and body keys.

Support all equipment networking, network port connection, standard TCP/IP protocol, you can remotely monitor the operating status of the device in real time, remote adjustment of the parameters of the device.

Alarm function: LED indicator alarm. If an abnormal alarm occurs after the system works stably, the alarm indicator is steady red.

The screen displays the IP address and other parameters.

Due to the small emission power of this product, compared with traditional shielding technology, the radiation level is lower and harmless to human health.
