e/Chirp spread spectrum

Information
has gloss	eng: Chirp spread spectrum (CSS) is a spread spectrum technique that uses wideband linear frequency modulated chirp pulses to encode information. A chirp is a sinusoidal signal whose frequency increases or decreases over a certain amount of time. Below is an example of an upchirp - as you can see, the frequency increases linearly over time.
lexicalization	eng: Chirp Spread Spectrum
instance of	(noun) (electronics) the transmission of a signal by using it to vary a carrier wave; changing the carrier's amplitude or frequency or phase modulation

Meaning
German
has gloss	deu: Der Begriff Chirp Spread Spectrum (CSS) bzw. Zirpenfrequenzspreizung bezeichnet eine Modulationstechnik, welche zur Frequenzspreizung (engl. Spread Spectrum) Chirp-Impulse (= Zirpen) verwendet. Dieses Modulationsverfahren wird zur drahtlosen Datenübertragungen auf kurzen Distanzen wie den Wireless Personal Area Network eingesetzt und ist in dem Standard IEEE 802.15.4a normiert .
