Fiber Optic Repeaters · Cell Phone Boosters · Jammer Systems · Smart NMS · Antennas — factory-direct with OEM/ODM support
Fiber-fed coverage with clean signal and zero self-oscillation. Star / chain / hybrid networking, 1 master up to 32 remotes — for tunnels, basements, large buildings, mountains and hydropower stations.

Digital processing, carrier-grade signal quality, master + remote units, cascade expansion.

High-power remote unit, 3,000-10,000+ m² per site — the workhorse for tunnels and campuses.

Cost-effective fiber-fed solution, simple and stable — common in mid-size coverage projects.

4G NMS / cloud platform version — remote monitoring, alerting and batch O&M for multi-site networks.
Tri-network (2G/3G/4G/5G) amplification, plug-and-play. Choose by coverage: home 300 m² → project 10,000 m².

For apartments and shops, approx. 300 m², zero-config, tri-network boost.

Villas, offices and restaurants, approx. 500 m², ALC auto level control.

Floors, garages and malls, 500-3,000 m², multi-band options, networkable.

Large plants and campuses, 3,000-10,000 m², mixable with fiber repeaters.

Dedicated elevator car coverage — calls and data stay alive up to 30+ floors.

Leaky cable / antenna array solutions for kilometer-scale tunnels and mines.

SA series smart upgrade: cloud monitoring, alerts and batch configuration.

Panel / yagi / omni antennas, feeders, splitters, couplers and connectors.
Full-band 2G-5G signal management for standardized exam centers, courts & law enforcement, correctional facilities and secure meetings — supplied only to authorized institutional buyers.

Classroom / meeting-room level, 60-200 m² per unit, one-button start.

High-power zoned coverage 500-3,000 m² — for cell blocks, perimeters and large exam centers.

Directional sector control — courtroom and interrogation-room precision without disturbing neighbors.
4G NMS / cloud centralized control: zoned & scheduled operation, status patrol, alerts.
