FM Broadcast
FM radio operates in the 88–108 MHz range, typically broadcasting signals that typically measure under 1 µV/m at typical tower offset distances. Effective shielding requires attenuation levels of at least 60 dB to block these signals- orders of magnitude lower than OffGrid's shielding in this range.
LTE Bands
LTE networks operate from around 700 MHz up to 2.7 GHz, varying by carrier and region. Lower bands (700–900 MHz) offer better coverage, while higher bands (1.7–2.7 GHz) provide higher speeds. Effective shielding requires at least 60 dB attenuation.
5G Cell Bands
5G spans 600 MHz to 4.2 GHz for mid-band coverage and 24–40 GHz for mmWave. Shielding requires on average 60 dB attenuation for isolation, but at the higher band much less and is line of sight.
WiFi and Bluetooth
Wi-Fi operates at 2.4 GHz, 5 GHz, and 6 GHz, while Bluetooth shares the 2.4 GHz band. Both enable short-range wireless connectivity, and effective shielding requires around 80 dB attenuation to block signals and maintain privacy.
GPS and GNSS
GPS/GNSS signals typically use the L1 band at 1575.42 MHz and may include other bands like L2 and L5. These low-power signals are line of sight and easily shielded with 60 dB attenuation to prevent location tracking and interference.
NFC Band
Near Field Communication (NFC) operates at 13.56 MHz for short-range communication. These low-frequency signals are easily shielded with low levels of attenuation, effectively blocking data transfer and protecting devices from unauthorized contactless communication.
EMP
Electromagnetic pulses (EMPs) span from kHz to GHz frequencies, with rapid, high-energy bursts that can damage electronics. OffGrid bags’ MIL-STD-188-125-2 compliance ensures effective shielding, providing protection against EMP-induced failures by attenuating high-frequency energy and preventing critical disruptions.
Your Shielding Specialists
FAQs Answered
Our engineers and security pros share their insights on keeping your devices safe from all threats, big and small.
How do Faraday bags block signals?
Faraday bags block signals using a multi-layered, conductive shield that surrounds your device and absorbs or reflects electromagnetic waves. This creates a two way sealed barrier for electromagnetic energy that prevents external RF signals (such as Wi-Fi, Bluetooth, cellular, and GPS) from reaching your device, ensuring your data and privacy remain secure.
What is MIL-STD-188-125-2 compliance?
It’s a military standard that ensures protection against high-level electromagnetic pulses (EMPs). OffGrid bags meet this standard, providing top-tier shielding against even the harshest conditions.
Do Faraday bags protect against EMPs?
Yes. Our bags are designed to block electromagnetic pulses, safeguarding your devices from sudden, high-energy bursts that could otherwise damage or disable electronics.
How do I know my bag is working?
A quick and easy way to test your bag is by playing music through Bluetooth headphones and placing your phone in the bag. The music should cut out immediately. You can also use the RF Tester Pro app available on iOS and Android.
How long does a Faraday bag last?
With proper use and care, a high-quality Faraday bag can last for years, maintaining its shielding effectiveness through everyday wear and tear. At OffGrid, we've put a ton of effort into creating the longest lasting bag by improving out material stack and adding non-abrasive layers which reduce material wear. We stand by our product with a no questions asked 1 year warranty. If you ever have any issues with your purchase, contact us and we'll take care of you.
Will my device still work while in the bag?
It won't work for communication, but non connected function (i.e. alarms, downloaded media, offline apps, ect) will work so long as your phone is powered on. Your bag blocks all signals, so your device won’t receive calls, texts, or notifications until removed from the bag.

The backpack is of superior quality, its materials, functionality, compartments, design, everything is truly excellent, even better than it looks in the posts. The protection for all devices is simply perfect.
R
I like the bag a lot. It doesn’t look like a tactical bag and it has multiple compartments to handle a lot of cords or accessories. Very spacious and well made. If I had to criticize then I would offer to add color options for this looking to appear more trendy.
D
Love how many pockets the bag has and it's very easy to stay organized with how things are separated. Holds everything I need and it even has a built-in "poncho" for the bag so it won't get wet.

Excellent quality
W
Well-made, great materials, excellent zipper action. Storage sizes and locations are ideal and well executed. Only flaw is laptop Faraday sleeve is too wide at the corners, when in use, for the zipper to properly function near these two corners. Other than that, this thing Rocks!
Z
This thing is awesome! It's tough, water resistant and the multi functionality of the numerous pockets combined with the waterproof cover that folds out of a bottom pocket make it a must buy for long trips and off grid journeys. Worth every penny.

I love the quality and the design. It has military grade faraday pockets for a laptop, phone, tablet and keys. It also has a strengthened compartment for your glasses. And a really useful rain cover on a hidden pocket. The only point I dislike (and here it is about a personal preference, not a default) is the fact that it is a bit too big for an everyday use when walking. Even though, it is a truly comfortable backpack to wear. And it fully deserves 5 stars.

The backpack is surprisingly heavy…without any contents.
I ordered a separate case for my phones, with the see-through window. While sealed, my phone still had one bar on LTE.

This is Amazing and quality of products is great. High quality and lots of storage, it's only missing bulletproofing 😂. This is a great product and its comfortable too. You even have a eyewear compartment it's a built-in sunglasses/eyeglasses case. Storage on storage!!! Thank you for making quality products!!
