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 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 test data for custom products, and/or simulations.

In all cases, shielding effectiveness exceeded the requirements specified by MIL-STD-285, IEEE 299 and Human RF exposure limits as set forth in FCC OET Bulletin 65.

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

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