Test Information
Introduction Test Information Test Results

Unless otherwise noted, identical tests were conducted by three independent laboratories. The frequencies, power levels and shielding effectiveness presented on individual product specification pages appearing on this website were derived using test equipment comparable to our in-house test equipment listed near the bottom of this page.

The following table chronologically presents AegisGuard™ products tested using ASTM D4935-99, MIL-STD 285, IEEE-STD-299, and proposed IEEE 802.11ac, ad, ax - ETSI EN 302 567 procedures. All models above 30 GHz. were initially developed under contract for specific customers, and tested by them and ourselves in-house prior to introduction as standard products.

Globally accepted safety standards for 4G-LTE and 5G operating frequencies above 96 GHz. do not exist. Shielding effectiveness results for frequencies above 96 GHz presented in specification pages on this website are derived from in-house generated frequencies, customer live device, network and sampling test test data for custom products, and simulations.

In all instances, shielding test results exceed available industry and regulatory safety standards .

Unless otherwise noted, the following table chronologically presents AegisGuard™ products tested in-house, and by each independent laboratory, prior to product announcements. Scroll down for test equipment information.

Random sampling tests for each production lot is performed in-house prior to packaging.
