The auctioning of the C-band for 5G use has raised concerns in North America that signals could interfere with aircraft altimeter operations. 5GTW asked a filter engineer and a test expert if there’s a problem and how to fix it.
In a video interview with 5G Technology World, Resonant’s Mike Eddy explains how RF filters keep wanted signals in an interference out. It’s all in the physics. As bandwidth gets crowded, governments auction more spectrum to accommodate our insatiable demand for data. While 3G used frequencies around 1 GHz, 4G expanded to around 2 GHz.…
RF filters have always been an important part of mobile devices, but in the 5G era, they are the key to unlocking the promised high bandwidth that will drive many 5G use cases.
