With Extension Request Denied, Comments on UWB Petition Due to FCC August 19

Spectrum regulators have denied a request for an extension to file comments on a petition to rewrite the rules governing Ultra-Wide Band (UWB), a wireless technology that spreads the content of a signal across hundreds of megahertz of frequencies and poses a potential interference risk to GPS.

Perceived Environment Aided GNSS Single Point Positioning: An Example Using LiDAR Scanner

GNSS positioning is strongly challenged in urban canyon areas. The signal reflection induces multipath and non-light-of-sight (NLOS). These signal blockages and reflections are caused by the obstacles of signal transmission between the satellites and receiver.

FCC Weighs Broad Changes in Ultra-Wideband Rules

GPS Innovation Alliance Asks for More Time to Respond

Spectrum regulators are considering a request to modify tough restrictions on devices and systems relying on Ultra-Wideband (UWB) technology, an approach to using frequencies that skips across wide swaths of spectrum instead of confining its signals to distinct, narrower bands.
