Our Technology – Ultimate EMF Protection

Laptop with and without DefenderShield shielding technology DefenderShield® is proud to offer the best and most effective EMF shielding in the world. We provide functional and state-of-the-art Electromagnetic Radiation (EMF) protection for ultimate safety while using today’s modern mobile technology.

Our product lines incorporate a range of sophisticated, non-toxic, human safe alloys and materials that conduct, absorb, and dissipate up to 99.9% of EMF radiation frequencies from 0-90 GHz, including the entire 5th Generation spectrum. No other mobile device shielding in the world blocks frequencies up to 90 GHz.

Modern science knows of no other way of shielding this broad spectrum range of radiation from devices such as laptops, tablets and cell phones, without utilizing a multi-layer solution to block both ELF and higher frequency RF emissions like 5G.

Types of Electronic EMF Emissions:

DefenderShield ELF Icon Color

Extremely Low Frequency (ELF) Radiation

0 Hz to 300 Hz

A low-power emission generated by any device with a power source (a battery or wall plug). This radiation is at the lowest end of the spectrum. It does not travel far, and is more comparable to an energy leak than an energy transmission.


DefenderShield Cellular RF Icon Color

Radio Frequency (RF) Radiation

300 Hz to 300 GHz

Emitted by wireless signals and networks (WiFi, Cellular Network, Bluetooth, etc.). This radiation is also called microwave radiation. Please note that consumer wireless signals and networks don’t yet reach 300 GHz. Today, wireless bands use frequencies around 600 Hz – 6 GHz.


DefenderShield 5G Icon Color

Fifth Generation (5G) Wireless Radiation

Low / Mid Band:
600 Hz – 6 GHz

High Band / mmWave:
10 GHz – 100 GHz

Technically classified as RF radiation, 5G is split into 3 frequency bands. Low- & Mid-band 5G is used the vast majority of the time (under 6 GHZ) because they travel farther than high-band 5G, which uses a new category of wireless waves above 10 GHz, called millimeter waves. Effects of mm Waves have not been studied yet, and are now only in small 5G cell tower sites (in dense urban areas) and fixed wireless cable systems. You must have a new 5G-enabled device to connect to a 5G network.


Our Different Types of Shielding:

We provide the best shielding technology available for all of our different product lines. Some products are able to include EMF protection up to 90 GHz, while other products, like clothing items, require different EMF protection materials specific to that product’s functionality. Below you will find the different categories of shielding we offer. Please note: We are always working to develop even more effective materials for all product lines, so these categories are subject to change.

RF Wireless Advanced Shielding

DefenderShield clothing and fabric shielding products contain our RF Wireless Advanced Shielding Technology. This shielding is the gold standard for blocking the wireless EMF radiation emitted by today’s mobile devices. Due to the soft, flexible, or elastic properties of these items, it is not functional to include the less flexible shielding materials needed to block frequencies below 300 Hz or above 10 GHz. Feel secure knowing that RF Wireless Advanced Shielding products block up to 99% of wireless (RF) signals up to 10 GHz, which includes low- and mid-band 5G frequencies used in most current 5G networks.

What it Blocks:
300 Hz – 10 GHz

DefenderShield Gradient New Thin Line

Signature Shielding Technology

Developed by DefenderShield CEO Daniel DeBaun, our flagship Signature Shielding Technology is capable of blocking 98.25% of Extremely Low Frequency (ELF) emissions, in addition to 99.9% of wireless Radio Frequency (RF) radiation up to 10 GHz.

This shielding incorporates nanotechnology and is found in our Cell Phone Cases, Tablet Cases, and Laptop Shields. As hard-sided cases, they are able to block ELF, RF, 5G low- and mid-band signals, cellular, RFID, WiFi, and Bluetooth.
