Radio signal isolation
A shielded bag is designed to isolate the radio connections of the device inside. Check dimensions, closure and the manufacturer's specified frequency ranges.
Speech masking

Communication devices
Modems and two-way radios provide connectivity. Assess privacy and security features using the technical description of the specific model.
What to consider
- Purpose: a phone, car key, computer or meeting space.
- Compatibility: usable bag dimensions, frequency ranges, power and operating conditions.
- Performance checks: follow the instructions and test with your own equipment in the intended environment.
Signal blocking, sound masking and device detection are different functions. A feature of one product should not be assumed for the whole category.
