Vehicle-mounted all-band wireless signal blocking system, is a broadband wireless transmission interference equipment, all digital (DDS) modular design, simple operation, can be very convenient and fast in dynamic or static radiation shielding electromagnetic waves, to prevent criminals through radio remote control explosion and block through radio communication/leakage. It is mainly used for travel security of government personnel, border prevention, protection of large events and important areas, and is installed on the car to improve mobility and flexibility.

Interference mode: Based on all-digital (DDS) signal source synthesis interference source technology;

Interference direction: high-gain omnidirectional, the number of high-gain omnidirectional antennas on the vehicle level is not less than 14-18;

Interference frequency range: 20MHz ~ 6000MHz, 13-20 modules (optional), seamless coverage of the whole band;

Interference distance:

When the receiving level of the mobile communication terminal is ≤-65dBm(2G, 3G), the effective containment radius is ≥ 150m;

When the receiving level of the mobile communication terminal is ≤-95dBm(4G/5G), the effective containment radius is ≥200 meters;

Wireless remote control device in the receiving and transmitting device spacing of 50 meters (remote control transmitter power of 13dBm) under the condition of effective sealing radius ≥1000 meters;

Under the condition that the distance between the receiver and transmitter is 100 meters (transmitting power is 35dBm), the effective sealing radius of the digital walkie-talkie is ≥250 meters;

Cordless telephone in the main and auxiliary distance of 50 meters, the effective sealing radius ≥250 meters;

Bluetooth, WLAN, WIFI, RFID under the condition of receiving and transmitting device spacing of 20 meters (transmit power of 15dBm), effective sealing radius ≥100 meters;

The dry pass ratio of the UAV remote control and the UAV (civil small UAV, reference RCS=0.01 square meters) is at 10:1, and the effective interference countermeasures distance is ≥2000 meters.

Working mode: Interference frequency band selection has two modes: automatic and manual selection;

The whole equipment consists of 13-20 modules (optional), and the plug and pull design provides convenience for the power upgrade, change and maintenance of the equipment in the future. The problem of one module will not affect the normal operation of other modules;

Each module has a separate R485 interface, and support software Settings to modify module power, module frequency can be set 1-8 independent frequency bands;

Equipment support can avoid the separate setting of "Police law enforcement special frequency" to avoid affecting the normal use of "police communication system";

The antenna of the equipment is based on the collapsible design, which can remotely lift all the antennas with one click, which is convenient for driving safety;

The equipment is based on intelligent temperature control and heat dissipation system to ensure that the host can work continuously for a long time;

The host of the device is based on the VSWR standing wave ratio protection mechanism to ensure the overvoltage and overcurrent protection of the host.

Customized vehicle-type wire control remote control, convenient for operators to switch on and off the host during driving;

Customized lightweight aviation aluminum protective box, based on equipment installation, transportation, internal structure solid design, to ensure the safety of equipment under different road conditions, long-term stable work;

After the modification is completed, the opening and closing of each frequency band can be controlled respectively through the wire control box in the cab, and the one-button start;

The rear seat of the car is completely reserved, with power generation (optional generator and lithium battery), does not occupy the space and weight of the car, does not produce exhaust gas and noise, when the equipment is not used, the roof antenna can be automatically hidden, convenient for customers to carry out other tasks;

The machine built-in efficient intelligent cooling fan and heat sink to ensure the stable operation of the equipment, extend the service life of the equipment;

Function introduction

The system can effectively shield the functions of the digital civil and industrial wireless remote control devices and wireless mobile communication devices that are often used by criminals in a certain range, so that they lose the ability to receive or decode signals and instructions, and cannot achieve their intended electrical signal output and action.

Simple ground preparation connection and operation, for the simple training of the operator has the ability to quickly start into the working state. Ability to work continuously for unlimited time in complex situations.

With perfect self-protection function, it is not damaged in the case of power supply, antenna and extremely harsh environment.

Modular structure design, reduce equipment maintenance time. The auxiliary circuit and interference module are designed to support a certain degree of equipment upgrading.

It does not affect the functions and indicators of equipment outside the operating frequency range of the jammer (on-site wireless communication and non-wireless communication equipment), and does not affect the frequencies of public radio, television and aviation communications that are prohibited from interference under any circumstances according to the law.

In line with the relevant requirements of GB 16796-2009 safety alarm equipment standard, to achieve the maximum protection of users.
