UWB technology can spread a signal across gigahertz of spectrum while using only picowatts of power per hertz, causing the signal to appear as background radiation, or the noise floor, to conventional narrowband receivers.
Notes on verification
Technical claim corroborated by multiple independent sources (Rogers Corp, patent documentation, Android Authority) describing UWB's wide bandwidth spreading and low power spectral density causing signals to fall near/below the noise floor for narrowband receivers. Core exact phrasing traces to a single original article, but underlying technical substance is well-supported by regulatory and technical documentation.
