FWR Faraday bag Small Gen. M - with sealing option

FWR Faraday Bag Generation M is a professional shielding pouch for the secure storage and transport of mobile phones and other wireless devices. Compared to the standard M version, it adds the option of sealing the bag, which makes it possible to verify whether it has been opened without authorization during transport or storage. Thanks to its 12-layer construction, magnetic closure, and measured attenuation of up to 102 dB, it effectively limits device communication with 5G networks, mobile networks, Wi-Fi, GPS, and Bluetooth as well as RFID and NFC. An attenuation of 102 dB means a signal weakened more than 10 billion times — for surrounding networks, the device is invisible.

The pouch is designed for the needs of police, military, forensic experts, and court-appointed experts who need to protect devices not only from wireless communication, but also from unauthorized handling during transport or storage. At the same time, it is also suitable for companies and regular users who want to protect their privacy, data, and devices from wireless communication, tracking, or remote access.

Main benefits:

• shielding of 5G, mobile signal, Wi-Fi, GPS, Bluetooth, RFID, and NFC,
• high measured attenuation of up to 102 dB (signal weakened more than 10 billion times),
• 12-layer shielding construction for reliable signal limitation,
• magnetic closure without Velcro,
• option of sealing the bag to check for unauthorized opening,
• made from high-quality and durable material,
• lightweight, durable construction for use in the laboratory and in the field,
• suitable for forensic securing of mobile devices,
• internal dimensions 22,5 × 14 cm, suitable even for the largest current phones.

Magnetic closure instead of Velcro

Magnetic closure is practical especially for forensic work and handling evidentiary material. Unlike Velcro, it reduces the risk of mechanical damage to gloves or unwanted contamination of the stored device during transport. At the same time, it makes proper and repeatable closing of the bag easier, which helps minimize the risk of insufficient shielding caused by incorrect closing of the Velcro. Thanks to this, it is comfortable and reliable even for regular users. This version also allows the bag to be sealed after closing. The seal helps verify during transport or storage whether the bag has been opened without authorization and whether the stored device has been physically handled.

What fits inside the bag

The internal dimensions of 22,5 × 14 cm comfortably accommodate even the largest current smartphones (e.g. iPhone Pro Max or Samsung Galaxy Ultra), including with a protective case.

FWR Faraday Bag Generation M Small with sealing option is suitable for:

• securing mobile phones during digital forensic analysis,
• transport and storage of devices with the option to check for unauthorized opening,
• handover of evidentiary material between workplaces or persons,
• internal security processes, audits, and controlled handover of devices,
• reducing the risk of device tracking,
• business meetings and security-sensitive meetings,
• protection of company and personal data,
• storing a phone in situations where you do not want it to communicate in any way.

Technical parameters:

• internal dimensions: 22,5 × 14 cm,
• closure type: magnetic, with sealing option,
• construction: 12-layer shielding structure,
• maximum measured attenuation: up to 102 dB,
• verified shielding: 5G, mobile networks, Wi-Fi, GPS, Bluetooth, RFID, NFC,
• testing: according to ASTM D-4935-2010, IEEE Standard 299-2006, and MIL-Standard 285.

For maximum effectiveness, we recommend placing the entire device inside the bag, carefully closing the magnetic closure, and verifying before use that the pouch is properly closed. The measured attenuation values of Generation M according to ASTM D-4935-2010, IEEE-Standard 299-2006, and MIL-Standard 285 can be found here.

Frequently Asked Questions (FAQ)

What is a Faraday bag used for?

A Faraday bag is used to shield wireless devices from external signals. It is used in digital forensic analysis, safe device transport, or privacy protection.

Is the Faraday bag also suitable for regular users?

Yes. Although it is designed for professional use, it is also suitable for companies, managers, and users who want to reduce the risk of tracking, eavesdropping, or remote device communication.

Does FWR Faraday Bag Generation M block 5G signal?

Yes, Generation M is verified for shielding 5G signal and at the same time limits communication via mobile networks, Wi-Fi, GPS, Bluetooth, RFID, and NFC.

Will a mobile phone fit inside the bag?

Yes, the internal dimensions of 22,5 × 14 cm are suitable even for the largest current phones. Before purchase, we recommend comparing the dimensions of your device with the internal dimensions of the pouch.

Can a phone inside the bag be called?

No — that is exactly the purpose of the pouch. Inside, the device loses signal, it cannot be called, its location cannot be found, and it cannot be accessed remotely.

Does a phone discharge faster inside the bag?

A switched-on phone without signal may consume more energy because it is trying to search for an available signal again. For long-term storage, we recommend airplane mode or switching it off.

What is the difference between magnetic closure and Velcro?

Magnetic closure is easy to use, does not wear out in the same way as Velcro, and during forensic handling reduces the risk of catching or damaging gloves.

How do I know the bag works?

Place the device inside, close the pouch, wait at least one minute, and check whether it has lost access to the mobile network, Wi-Fi, Bluetooth, or location services. With a phone, you can also try calling it — the call should fail and the device should be unavailable.
