Signal Jammer Systems (Institutional)

Jammers are radio-interference equipment and strictly regulated in most countries. We supply only to authorized institutions: examination authorities, courts, police, correctional services and security departments. Purchase requires institutional authorization documents, and operation must comply with local radio regulations. We do not sell to private individuals, and we advise verifying legality in your jurisdiction before inquiry.

Boundary control is the core of system design: ① adjustable output power matched to the target area; ② directional antennas to concentrate energy inside the controlled room; ③ optimized unit placement per building structure. We perform site survey and field-strength estimation so the boundary stays clear — controlled area blocked, surrounding offices unaffected.

Two approaches: ① band customization — the staff radio's dedicated frequencies are excluded from the jamming list (supported by independent band switches); ② zoned control — office areas and cell blocks are covered by separately controlled units. We align the band list with the facility's technical department before design.

Effective radius depends on distance to nearby base stations, wall structure and target bands — areas close to base stations have stronger incoming signals and need more power. We recommend a site survey; we provide free remote assessment and, for key projects, on-site survey with unit placement drawings and acceptance criteria: "no signal inside the controlled area, normal service outside".
