Back Pack Jammer

Kya hota hai: Portable, backpack‑style device jo nearby wireless signals (cell, mic transmitters) ko disrupt karne ke liye RF/ultrasonic interference emit karta — conceptually portable privacy tool.

Use‑cases (authorized only): Law‑enforcement, controlled security sweeps, or authorised protective details—private/unregulated use aksar illegal hoti hai.

Limitations: Effective range choti hoti hai (meter se kuch 100s of meters, model pe depend), and walls/obstacles signal ko reduce karte hain.

Legal & safety warning: Bina permit use ya sale karna many countries mein illegal ho sakta hai; emergency calls and public safety communications may be blocked — use only with proper authorization.

Safer alternatives: Phone lockboxes / Faraday bags, white‑noise audio masking devices, strict no‑phone policies, or secure meeting rooms are legal options for privacy.

Agar procurement soch rahe ho: Sirf licensed vendors se lein, vendor se regulatory compliance certificates maangein, aur local telecom regulator se NOC/permit confirm karein.
