The received power of GPS and Galileo navigation signals at the antenna output of a user receiver is typically extremely small, from approximately –165 up to –150 dBW, which makes them inherently ...

The FCC has adopted a Notice of Inquiry and a Notice of Proposed Rulemaking seeking comment on the use of a so-called “interference temperature” model when determining RF interference. The ...

Radio frequency interference (RFI) remains a critical challenge in synthetic aperture radiometry, where precise reconstruction of brightness temperature maps is essential for environmental, ...

When subjected to very strong interference, a GNSS receiver can be totally blinded and stop working. This is often the scope of intentional jammers. However, in a number of cases the presence of ...

Electrical noise often affects how proximity switches operate on plant floors. Much of the equipment found in factories creates radiofrequency and electromagnetic interference (RFI/EMI). The list of ...

We all know the familiar dialogue from the flight attendant: All electronic devices must be turned off now to prevent interference with the aircraft navigation system. After we have reached our ...

WASHINGTON Broadcasters continually lament the increase in RF noise in the environment. Why? Because it effectively limits a radio station s reach. Just over a year ago, the FCC s Office of ...

Tokyo, Japan—Quellan Inc. announced the QNx220, an RF noise canceller for advanced mobile communications products. Based on Quellen's patented CSP noise canceling technology, the ultra small CMOS IC ...

Sometimes the old tricks are the best. [Kevin] learned an old trick about using a ‘scope to sniff RF noise and pays it forward by sharing it in a recent video. He uses an oscilloscope. But does he ...
