Twelve modules work independently, RF power of each channel is 2~3W;

Particularly strengthened the power of push for 3G/4G/5G, in full assurance of per channel output power at least 2W;

With expansion space of 6G or other wireless frequency bands in the future；The output channel(frequency band)can support up to 24 channels;

Exquisite structural design,Invisible handle trough embedded in the back,It is not only convenient to carry, but also suitable for wall mounting;

Industrial switch power supply, with precision voltage regulator circuit, to ensure the normal work of the host;

Fully sealed protective casing design, waterproof, dustproof, prevent from sabotage and other questions in special application field;

High temperature resistant environment, can quickly transfer heat to the cooling base (built-in ventilation duct cooling fins), to avoid local heat accumulation;

Professional circulation air duct type heat dissipation base structure, the lower end of the rapid inhalation of natural wind, the upper two sides of the heat removal, to ensure that the equipment 24 hours stable work;

Built in 4 ultra quiet fans to draw out hot air,Adjustable fan speed;No noise during working time;

Stable performance, long service life;

Harmless to human body;
Extension interface with the function of intelligent networking linkage, networking way: power carrier + wireless, or by RS485 or CAN BUS;

Considerations

Jamming range is closely related to the signal strength in the field and may be affected by the system of mobile phone;
Factors that affect jamming range include but not limited to: distance of base station, jammer’s orientation, obstacles, wall’s material quality, jammer’s installation height and mode, etc;
Strictly factory test, like aging test. When client receives the machine, please check whether there are something wrong with our device in transit, such as parts fall off , and contact with dealer or manufacturer, for repairing timely;
Installation height is recommended to be 1.8 to 2.5 meters. Install in areas with no obstructions between the target positions. Antenna must be vertical, or antenna is vertical upright on the desktop after breaking off 90 degree, make sure no AC power lines or other audio and video line around antenna in range of 0.2 meters;
In order to avoid possible interference with some electronic devices during use, keep the following common device away from 1 to 2 meters: audio, wireless microphones, radios, computers, TV, Wi-Fi routers, etc.;
Motherboard Design

The RF channel modular and each channel work individually
All the motherboard components are used SMT technology
All components are new and original

Advantages
1、Exclusive power amplifier heat sink, large heat dissipation base design

326x93x40mm large heat dissipation base，Fast absorption and emission of heat from power amplifier and power board

The natural wind (cold wind) goes up along the fin gap, bringing out the heat on the cooling teeth quickly and going up

A total of 4 ultra quiet cooling fans (almost no wind noise, adjustable speed) on both sides of the upper end discharge the hot air

2、Cold and hot air lower in and up out, waterproof and damage proof shell

3、The upgrade space is sufficient and can be expanded to 24 channels at most

Meet the upgrading needs of 6G or even 7G in the future;

Reserve the expansion space of dual radiator, dual 12 channel module (24 channels in total) and dual power supply;

Function upgrading, expansion, original parts are all reserved and never wasted.

OEM Customized Service

Frequency spreading can be done for Wi-Fi, GPS,Bluetooth, Intercom and wireless data transmit etc.
More than 50 units can provide screen printing OEM service.
Provide neutral device.
Engineering Application

In engineering application, the four corners behind the main engine are reserved with bolt holes for wall mounting, which        can be directly mounted on the wall:

The installation bolt holes on the back of the equipment can be installed with concealed hanging pieces (thickness 4mm), so as to keep the gap between the equipment and the wall and ventilate;

Silent fans on both sides of device, strengthened to cool the host and power supply

Built-in antenna protect it from personnel sabotage

Internal power supply protect it from sabotage and malicious power off

Waterproof design, available installation both inside and outside
