We have Faraday Radio Frequency RF shield nylon bags in stock. Specially made for us using stronger anti-RF fabric, we have tested this bag shields even our ultra long range Bluetooth beacons.
Faraday bags can be very useful during development when you want to bring beacons in and out of range or need to hide development beacons. They are also useful during setup when you want to shield uncommissioned beacons temporarily.
These bags were originally designed for military, intelligence and police agencies to prevent seized devices from being remotely altered. They shield WiFi, Bluetooth and phone signals up to 70dBm. They can also be used with phones and tablets for personal anti-radiation health reasons, preventing tracking or avoiding communication when you don’t want to be interrupted.
The smallest gap in a Faraday bag can cause radio leakage. Hence, the top has velcro to allow it to be rolled over and securely fastened for full radio blocking.
