Question

10) Which of the following is correct for Z-wave and Zigbee?
a. Both uses 2.4GHz frequency range
b. Both uses Direct Sequence Spread Spectrum (DSSS) modulation
c. Both technologies are mesh networks
d. Both uses Gaussian Frequency-Shift Keying modulation (FSK)
​

Answer 1

Answer:

B is the answer of the question

Answer 2

Out of the following options, Option c) Both technologies are mesh networks is correct for both Z-wave and Zigbee.

• Zigbee uses a 2.4 GHz frequency or a 915 MHz frequency, and Z-Wave uses a frequency of 908.42 MHz.
• Z-wave used Gaussian Frequency-Shift Keying modulation (FSK) while Zigbee uses Direct Sequence Spread Spectrum(DSSS) modulation.
• Only similarity between Z-wave and Zigbee is that the both technologies are mesh networks but there is still a difference in the way they operate in their mesh networks.
