Comparing Wireless Devices
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 ...
