 d. O-QSK

Answer 1

Z- wave is a wireless communication technology used for home automation purpose like smart lock .,lighting control,etc....

and Option C is correct ..
hope it will help dear ..

Answer 2

Answer: C. GFSK

The modulation scheme followed b the Z-wave is Gaussian Frequency Shift Keying also known as GFSK. So, the correct choice of answer for the given question from the given list of possible answers is: c. GFSK.

As described by Wikipedia: “Gaussian frequency-shift keying (GFSK) filters the data pulses with a Gaussian filter to make the transitions smoother. This filter has the advantage of reducing sideband power, reducing interference with neighboring channels, at the cost of increasing intersymbol interference.”
