In a Move to Aid Spectrum Efficiency, FCC Begins Inquiry on Receiver Interference Standards
The FCC makes advancements towards more efficient spectrum use throughout the country.
WASHINGTON, April 26, 2022 — The Federal Communication Commission on Thursday voted to press forward on a proceeding designed to make spectrum transmissions in the United States much more efficient.
“By enabling more efficient use will facilitate the introduction of new and innovative wireless services that will benefit the American public,” said Paul Murray, associate chief of the Office of Engineering and Technology at the FCC, who introduced an inquiry titled, “Promoting Efficient Use of Spectrum through Improved Receiver Interference Immunity Performance.”
Receiver interference immunity performance refers to the ability of a radiofrequency receiver (as opposed to a transmitter) to reject interference. Typically, the agency focuses its rules on the transmitter side of radio systems.
But, the FCC said, “receivers and receiver interference immunity performance play an increasingly critical role in enabling more efficient spectrum use,” age agency noted in its fact sheet circulated prior to the meeting.
In it, the FCC highlighted how, increasingly, “the receiver interference immunity performance associated with incumbent services operating in spectral proximity to new users or services has been a major consideration.”
For example, the ability of incumbent service receivers to reject signals outside their intended band has been relevant to the timing and scope of the introduction of new services, such as the Ligado and the 3.7 GigaHertz (GHz) band proceedings, the agency noted. There, the FCC adopted operating conditions and rules to enable the introduction of new operations into frequency bands with various incumbent users operating under different service allocations in the same band, adjacent band, or other spectrally proximate frequency bands.
“If our telecommunications system is going to meet the modern needs of our nation, every aspect needs to operate efficiently,” said Kathleen Burke, policy counsel at Public Knowledge. She endorsed the agency’s beginning the proceeding.
Emergency alerts strengthened
During the meeting the commission also approved for the public to comment on proposals that will strengthen wireless emergency alerts. “This pandemic has made crystal clear how important it is to have good data in an emergency. Accurate information is essential if we want to know what we need to do next. That is also true with Wireless Emergency Alerts. If we want to know where to go with this system next, we need to better understand it. That is why today we seek comments on how we can develop better data about the effectiveness of Wireless Emergency Alerts,” said Chairwoman Jessica Rosenworcel.
Rosenworcel also that Chief of Staff Travis Litman will be leaving the office and will be replaced by Narda Jones.
“We also welcome the uncommonly talented Narda Jones to the agency. She’s my new chief of staff,” Rosenworcel said. She comes to us from the Office of Science and Technology Policy at the White House.”
The FCC’s next Open Commission Meeting will be held on May 19.
