FCC Delays U-NII Device Certification Requirement

The U.S. Federal Communications Commission (FCC) has delayed until December 2015 its certification requirements for certain National Information Infrastructure (U-NII) devices.

The certification requirements, which were slated to take effect on June 2, 2015, apply to U-NII devices operating in the 5 GHz band. Such devices are used for short range, high speed wireless connections, such as Wi-Fi enabled local area networks used in public places to connect smart phones, tablets and laptop computers to the broadband network.

According to an Order issued on June 1, 2015, the Commission chose to extend the certification date in response to a petition from the Wireless Internet Services Providers Association, and in order to consider the merits of other petitions for reconsideration in connection with the Commission’s original Report and Order.

Near and Far Field Measurements with a Vector Network Analyzer

For optimal performance in over-the-air RF systems, antennas must meet specific requirements. Performance parameters like size, wind-loading, environmental ruggedness, transmission pattern, bandwidth, and power handling capability should be considered. Methods of measuring the transmission (or reception) pattern that determines antenna gain with a VNA will be examined in this article.

Read the complete text of the Commission’s Order delaying the implementation of U-NII requirements.
