Handheld Jammer

Purpose — Portable device designed to disrupt or block wireless signals (e.g., RF, Wi‑Fi, Bluetooth) within a limited area.

Modes — Can be broadband (wideband interference) or selective (target specific bands/devices) depending on model.

Portability & Power — Battery‑powered, lightweight units built for short‑duration, on‑the‑move use.

Range & Limitations — Effective only over short distances; performance depends on environment, antenna design, and signal strength.

Collateral Effects — Can unintentionally disrupt nearby legitimate communications, navigation, or safety systems.

Legality & Responsible Use — Often restricted or illegal for civilian use in many jurisdictions; intended for authorised/security applications only and must follow local laws.
