Description
xDon’t want to be disturbed? Let 4G phone and bluetooth signal blocker help you solve the problem. The device can suppress the main communication frequency bands (from traditional GSM and CDMA to 4G and even Wi-Fi). Instead of blindly conducting broad-spectrum interference, it selectively isolates information in a designated space. The non-logo design allows it to be hidden in places you don’t want to be noticed.
Don’t want to answer the phone? Don’t want to be disturbed? Let this fixed 4G mobile phone WiFi 2.4GHz signal jammer T-US-KM4 help you solve the problem.
The device can perform directional interference on major communication frequency bands (from traditional GSM and CDMA to 4G and even Wi-Fi). It is like a “signal butler”. Instead of blindly performing broad-spectrum interference, it is precisely controlled to selectively isolate information in a designated space without causing interference to the surrounding area.
This cellular phone scrambler for sale adopts a logo-free design. There are no obvious signs or display lights on the outside of the device. It can blend seamlessly into the surrounding environment and hide in places where you don’t want to be noticed.
For many jamming devices, starting up means waiting and configuration, but T-US-KM4 only needs to be connected to the power supply, and the device will automatically calibrate to adapt to the signal environment-all without any technical adjustments on your part. This plug-and-play, almost imperceptible use experience may even make people ignore its existence and silently protect your privacy.
The edge of the device is reinforced with screws, which is both firm and easy to maintain and repair later. With dedicated mounting holes, you can place it in a corner, under a table, or fix it to a vertical surface (such as a wall, bracket, etc.), and you can freely choose the appropriate installation location according to the environment.
The side is equipped with vents and low-noise fans, which can quickly dissipate heat through effective air circulation, without overheating and noise – only smooth, uninterrupted signal blocking.
