NextNav Inc. has issued a response to a Security Industry Association (SIA)-sponsored paper produced by Pericle Communications Company, disputing its findings on potential 5G interference in the lower 900 MHz band. Dr. John Kim, NextNav's Senior Vice President of Technology Development, criticized the paper's modeling as flawed and inconsistent with basic physics and engineering principles. NextNav's latest filing points out that Pericle's predicted 5G emission levels surpass even free-space conditions and that simulation errors led to a significant overstatement—by a factor of more than 10,000—of potential 5G impact in certain scenarios. The company urges the Commission to disregard Pericle's conclusions, emphasizing that unlicensed security devices can coexist with 5G in the band.
