Since the anti-interference performance of CDMA mobile phones is much better than that of GSM mobile phones, the portable jammer to prevent CDMA mobile networks are smaller than GSM mobile phones, but they are not much different. If necessary, the number of mobile phone signal interference transmitters can be increased to ensure the effect of traffic congestion. In some particularly important areas, the shielding effect of CDMA mobile phones is very good.
There is a small WiFi Bluetooth jammer, a wireless LAN transmission signal and a cell phone jammer for market surveillance. Using advanced foreign technology, 24 hours a day, 365 days of continuous work, using imported parts of the communication suppression device, improved domestic mobile communication with power based on advanced high-tech products, highly recommended for school test rooms, dormitories, libraries , Prisons, camps, military, troops, churches, secret meeting rooms, etc.
The angle of the signal interference antenna can be adjusted freely. According to the interference frequency, each stop band can be turned on and off, and the intensity can be set.
