Question

The PHY and MAC layers in ISA 100.11A are based upon; a. IEEE 802.11a b. IEEE 802.15.4 c. IEEE 802.15.6 d. IEEE 802.11g

Answer 1

Physical and MAC layer uses in ISA 100.11A are based upon IEEE 802.15.4 ...option b

Answer 2

The PHY and MAC layers in ISA 100.11A are based upon; b.IEEE 802.15.4 IEEE 802.15.4 is used for low rate wireless personal area network.

It has access to the physical layer and media access control.

This IEEE 802.15.4 is controlled and maintained by IEEE 802.15, which is defined in the year 2003.

The main purpose of IEEE 802.15.4 is to provide basic network connectivity to the wireless personal area network which is cost effective and communicates between devices.
