Wireless networks use one of four primary wireless standards, and many devices support multiple standards. Table 8-1 shows the common wireless standards in use today.

802.11 wireless standards are covered in more depth in Microsoft Windows Networking Essentials (Wiley, 2011), which covers exam 98-366.

Table 8-1: IEEE 802.11 Wireless Standards

IEEE Standard Speed Base Frequency
802.11a 54 Mbps 5 GHz
802.11b 11 Mbps 2.4 GHz
802.11g 54 Mbps 2.4 GHz
802.11n 300 Mbps 2.4 GHz or 5 GHz

The Speed column in Table 8-1 shows the maximum speed possible with these standards. However, various types of interference can potentially reduce the achievable throughput speeds. Also, IEEE ...
