What is the maximum data transmission speed of IEEE 802.11b wireless networks?
A.
54 Mbps
B.
600 Mbps
C.
600 Gbps
D.
11 Mbps
Explanation:
The maximum data transmission speed of IEEE 802.11b networks is 11 Mbps.
The IEEE 802.11b standard applies to wireless LAN networks that use radio waves as the
transmission medium. These networks each have a separate media access control mechanism,
known as Carrier Sense Multiple Access with Collision Avoidance (CSMS/CA), that works like the
CSMA/CD mechanism used by the Ethernet. The difference is that in this protocol, when a computer
sends its signals, the receiving computer performs a cyclical redundancy check and sends an
acknowledgement message to the sending computer if no error is detected. Answer option A is
incorrect. The IEEE 802.11a and IEEE 802.11g networks have data transmission speeds of 54
Mbps.Answer option B is incorrect. The IEEE 802.11n network has maximum data transmission
speed of 600 Mbps.Answer option C is incorrect. There is no such standard that has a maximum data
transmission speed of 600 Gbps.
