Which IEEE protocol defines wireless transmission in the 5 GHz band
with data rates up to 54 Mbps?

A.
IEEE 802.11b

B.
IEEE 802.11g

C.
IEEE 802.11a

D.
IEEE 802.15

Explanation:
IEEE 802.11a specifies high-speed wireless connectivity in the 5
GHz band using Orthogonal Frequency Division Multiplexing with
data rates up to 54 Mbps.
IEEE 802.11b specifies highspeed wireless connectivity in the 2.4 GHz ISM band up to 11 Mbps.
IEEE 802.11g is a proposed standard that offers
wireless transmission over relatively short distances at speeds from
20 Mbps up to 54 Mbps and operates in the 2.4 GHz range (and is
therefore expected to be backward-compatible with existing

802.11b-based networks).
IEEE 802.15, defines Wireless Personal Area Networks (WPAN), such as Bluetooth, in the 2.4-2.5
GHz band. Source: IEEE Wireless Working Groups
