What is the transfer speed of 802.11b?

  1. 11Mb/sec

  2. 54Mb/sec

  3. 150 to 600Mbps

  4. 866MBps to 1.3Gb/sec

The correct answer is: 11Mb/sec

The transfer speed of 802.11b is 11Mb/sec, making it the correct answer. This wireless networking standard, which was ratified in 1999, operates in the 2.4 GHz frequency range and was one of the first wireless standards to gain widespread acceptance. Its maximum theoretical throughput is 11 megabits per second (Mb/sec), which denotes the speed at which data can be transmitted over the network. The other options reflect the transfer speeds of different wireless standards. For instance, 54Mb/sec corresponds to the 802.11g standard, which offers higher speeds than 802.11b while still operating in the 2.4 GHz range. The range of 150 to 600Mbps is associated with 802.11n, which significantly improved data rates by utilizing multiple-input and multiple-output (MIMO) technology and can operate in both 2.4 GHz and 5 GHz bands. Lastly, the speeds noted as 866MBps to 1.3Gb/sec relate to the 802.11ac standard, which operates primarily in the 5 GHz spectrum and takes advantage of wider channels and advanced modulation techniques for much greater data transfer speeds.
