This customized 7 bands mobile phone network blocker is designed for complex wireless communication environments and is compatible with mainstream operators and special mission frequency standards around the world. It covers all common wireless signals within a 25-meter radius and is suitable for scenarios with high requirements for information confidentiality (examination halls, military bases, etc.).
T-US-B7 is equipped with 7 independent frequency band modules (factory pre-installed, support replacement and upgrade):
| CDMA | 860-894MHz |
| PCS | 1930-1990MHz |
| 3G | 2110-2170MHz |
| 4G 1 | 807-869MHz |
| 4G 2 | 2496-2690MHz |
| WiFi 2.4G | 2400-2484MHz |
| GPS L1 | 1570-1620 MHz |
Supports flexible selection from more than 20 common communication frequencies in the world:
- GSM / CDMA / DCS / PCS / 3G / LTE (2G–4G)
- Wi-Fi 2.4GHz / 5.2GHz / 5.8GHz
- GPS L1- L5 / RC 315/433/868 MHz / Lojack / FM / UHF and other common signals
T-US-B7 features:
Internally integrated hidden power adjustment knob, factory setting parameters have been optimized and cannot be easily modified to prevent naughty children from secretly reducing the shielding range.
After getting the device, you only need to connect all antennas and turn on the power, and the signal blocker will do the rest of the interference work for you.
The interference signal transmission method is specially optimized so as not to affect other equipment (electronic clocks, monitors, fire alarms, etc.)
The active and efficient heat dissipation system maintains the stability of the device during operation and supports 24-hour continuous operation.
