Question

which feature is responsible for interference-free access to the same channel at the different times by multiple users or nodes in IEEE 802.15.4
a.DSSS modulation scheme
b.CSMA-CA multiplexing
c.Transmission of shorts packets
d.Greater Channel Bandwidth​

Answer 1

CSMA-CA multiplexing feature is responsible for interference-free access to the same channel at different times by multiple users or nodes in IEEE 802.15.4

Explanation:

• CSMA-CA multiplexing stands for Carrier-sense multiple access with collision avoidance.
• This system is a multiple access method and is used in computer networking.
• Carrier seeing is used for sensing and is an essential component in wireless networks.
• Nodes are present to avoid any collision in the system and it transmits the data in packet form between multiple access points of users.
