All-in-One Outdoor Cell Signal Jammer

The all-in-one outdoor cell signal jammer detects the cellular signals in the environment, analyzes their strength and frequencies, synchronizes the uplink and downlink of TDD signals, and outputs the amplified jamming signals to target areas. The maximum output jamming power per radio channel is up to 100W. And the jamming signal could be distributed to target areas through one or multiple service antennas.


Product Description


The cell signal jammer can disrupt mobile communication services, including voice, SMS and data, by jamming downlink signals of mobile phones. The maximum output jamming power per radio channel is up to 100W. The jamming power could be adjusted locally from PC or remotely from NMS platform. 


The cell phone jammer is an all-in-one device which detects the cellular signals in the environment, analyzes their strength and frequencies, synchronizes the uplink and downlink of TDD signals, and outputs the amplified jamming signals to the target areas.


The jammer uses a whip antenna to receive the signal in the environment, and distributes the output jamming power through one or multiple service antennas. Combined with indoor distribution system, including RF cabling, splitters and indoor antennas, the distributed signal jammer can provide precise jamming signals to multiple floors and rooms. With directional panel antennas, jamming signal can cover big outdoor areas such as squares and channels. The solution is widely used in military areas, detention centers, prisons, research institutes, banknote printing plants, schools, and so on.



Networking Architecture






Key Features


Support all cellular bands

The jammer can support all the 2G/3G/4G/5G cellular bands of different mobile network operators and Wi-Fi frequency bands all in one system. And each frequency channel could be controlled independently.


Centralized monitoring and management

Support the query and monitoring of output power and other parameters; 

Stable and reliable monitoring through TCP/IP network.


No interference to operator’s base stations

With advanced TDD baseband decoding synchronization technology and high-precision switches to distinguish between uplink and downlink time slots, jamming signals are only transmitted in downlink time slots to avoid interference to TDD base stations. Filtering technologies are employed to minimize spurious emission of all radio frequencies.


No interference to devices of other frequencies

Out-of-band rejection of high performance can guarantee no interference to devices using other frequency bands such as UAV.


Green and smart

Automatically track the cellular signal in the environment, and output jamming signal on the corresponding carrier to reduce useless transmission power and improve transmission efficiency.


Timing function

Time-based control could be supported to set the operation time of the jammer.
