Blocking 5G with Faraday Cases

Do Faraday case block 5G signals?

The answer in short is "it depends." However, lets take a minute to unpack this.  5G is a term assigned to carriers (Verizon, T-Mobile & AT&T) to radio frequencies at the 28 GHz and 39GHz level.  Generally with higher frequencies we get higher levels of data transmission but lower range.  One estimate estimates the range to be able 500 meters or 1/3 mile.  

The wave legnths or much shorter than the 4G counterpart.  The idea then is to create a Faraday cage that is small enough to block these wavelengths. There are lab testing results on the site that show the interference level (dB) for one layer of Faraday material. To leave little to chance you will notice nearly all the cases have X2 shielding which is actually doubling the amount of shielding on each case. 

The cost up front is a little more on our end but doubles the amount of attenuation.

Monitoring 5G

From a field testing standpoint we have had heard no issues at our other agencies.  That said, nothing is impossible. For instance if you bag a phone and stand very close to a tower that signal has only the Faraday case to overcome as opposed it being some distance away and in your evidence building. 

Note: If any Faraday case “guarantees” it will block everything I would be skeptical.

A final note: 

All that said, we work with LEOs and others in the digital forensics field to create the cases.  When our customers send solid feedback we adjust the design to fit their mission needs.
