Radio-Enabled Products Using Radio Modules

In this first part of a two-part article, we’ll discuss the use of radio modules to enable wireless connectivity of electronic and consumer products, and how to approach radio, EMC and safety regulatory approvals in North America for radio modules and equipment which contain radio modules.

Radio and EMC Testing Considerations

Understanding radio compliance and electromagnetic compatibility (EMC) issues to help ensure that products meet regulatory testing requirements and customer expectations.

Lossy Material Quiets Leaky Air Vents

This article presents the results of experiments to measure the effectiveness of lossy material in reducing RF emissions from perforated air vents such as those commonly used on computer enclosures. The results show good performance compared to those with conventional metal vents.

Closed Loop Radiated Immunity Testing

This article describes a proposed addition to the IEC 61000-4-3 standard. This addition would allow detailed testing of a product while coordinating and documenting the frequency changes of the test.
