What is the maximum data transmission speed of IEEE 802.11b wireless networks?

Question

Options

• A54 Mbps
• B600 Mbps
• C600 Gbps
• D11 Mbps

• A
  4% (2)
• B
  6% (3)
• C
  12% (6)
• D
  79% (41)

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.
