CDMA frequency band transmission frequency: 851-894MHz DCS/PHS frequency band transmission frequency: 1805-1920MHz GSM frequency band transmission frequency: 925-960MHz TD-SCDMA frequency band transmission frequency: 2010-2025MHz WCDMA/CDMA frequency band transmission frequency: 2110-2170MHz 2.4G frequency band transmission frequency: 2400-2485MHz 4G1:2300-2400MHz 4G2: 2555-2650MHz 5G1:3400-3600MHz 5G2:4800-4900MHz
1. The latest multi-functional 5G model blocks signals such as 2G/3G/4G/5G/2.4G/WIFI.
2. Adopting a high hardness PVC plastic shell, with built-in heat dissipation aluminum strips and four fans for ventilation and heat dissipation. Excellent heat dissipation performance, sturdy and durable, ensuring long-term uninterrupted and reliable operation.
3. High quality built-in switch power supply and built-in antenna effectively prevent antenna damage. The effective shielding range is wider. Only one power cord is needed for use, which is convenient and fast.
4. Original imported chip with stable frequency and no frequency offset.
5. The shielding radius is 1-30 meters (a non fixed value, depending on the distance between the location and the base station and the strength of the signal).
6. Only block mobile phone signals, without affecting the normal operation of other electronic devices.
7. Ultra low radiation, safe and environmentally friendly, with no adverse effects on human health.
8. Only blocking the downlink frequency of the transmitting base station does not affect the uplink frequency.
9. Enhanced shielding devices have better effects and are suitable for use in places with strong signal strength.
