Why Choose Our Cell Phone Blocker

Full-band Blocking

Our phone blockers provide full-spectrum interference coverage, effectively blocking mobile communication signals across 2G, 3G, 4G, and 5G networks (including broadcast 5G), as well as wireless communication channels such as walkie-talkies. It also disrupts Bluetooth, Wi-Fi, and wireless transmission signals used by covert earpieces, bone-conduction headsets, and other connected devices.

Directional and Precise Coverage

The system features directional antennas with customizable power and frequency settings to adapt to different room sizes (10–500㎡) and signal environments. In small spaces, lower power and targeted band selection ensure effective shielding without unnecessary interference. For large or complex environments, higher power and flexible frequency adjustment provide complete coverage. This balance maintains security while preserving normal device operation.

Network Integration

Networked signal blockers are managed via a centralized platform, enabling intelligent remote control of multiple devices.

Key advantages include unified multi-area management, batch configuration and scheduling, real-time status and signal monitoring with alarms, dynamic adjustment of frequency and power for different scenarios, operation logging for auditing, and secure, scalable, multi-brand compatibility.

Guidelines for Anti-Leakage Implementation

1. Small Conference Rooms

For small conference rooms under 200㎡, we recommend using Dexinkang Electronic Technology's omnidirectional signal blocker model K-12-50W. This device features a one-touch on/off design for simple operation. Once powered on, it automatically creates a comprehensive omnidirectional signal shielding barrier, effectively blocking all commonly used wireless frequency bands including 2G, 3G, 4G, 5G, WiFi, and Bluetooth. Its compact size allows for easy installation or flexible placement, enabling it to blend seamlessly into the meeting environment and provide fundamental yet thorough communication security for small, private meetings.
To address higher confidentiality requirements, it can be supplemented with our adjustable directional signal blocker model N-14-120W. During meetings, if specific areas (such as the speaker's podium or confidential document storage points) or specific devices require enhanced protection, this directional blocker can be aimed at the target. Its unique adjustable frequency and power functionality allow for precise matching and intensified interference, effectively compensating for signal attenuation in specific directions from the omnidirectional device and ensuring no blind spots in information security.

2. Large Conference Centers

Large conference centers have vast spaces and complex human traffic flow, demanding higher performance from signal jamming systems. In such scenarios, deploying Dexinkang's N-14-120W main unit is an ideal choice. This main unit is not only powerful but also possesses excellent adjustability, supporting fine-tuning of shielding frequencies and transmission power. This key feature allows it to adapt flexibly to complex electromagnetic environments. Even in areas with strong base station signals, such as city centers or near signal towers, it can ensure effective shielding and stable operation by increasing the power for specific frequency bands.
To achieve cross-area signal coverage, a distributed antenna system can be used in conjunction with the N-14-120W main unit. The distributed antenna system utilizes multiple antenna nodes spread throughout the space to uniformly transmit the jamming signal generated by the main unit to every corner of the conference center, eliminating blind spots in signal shielding. Whether it's the main hall, breakout rooms, or corridors, all areas can receive comprehensive and stable signal shielding protection, effectively preventing information leakage through wireless signals and providing a solid foundation for the smooth operation of large conferences.
