What is the maximum data rate of an 802.11b network?

The maximum data rate of an 802.11b network is 11Mbps. This wireless networking standard, ratified in 1999, operates in the 2.4 GHz band and utilizes the Direct Sequence Spread Spectrum (DSSS) modulation technique, which supports the maximum throughput of 11 Mbps under optimal conditions.

Several factors can influence actual transmission speeds, such as environmental conditions, distance from the access point, and interference from other devices operating within the same frequency range. However, 11Mbps is the theoretical peak rate defined by the 802.11b standard, distinguishing it from faster standards like 802.11g and 802.11n, which are capable of much higher data rates.

Understanding this maximum data rate is essential for network planning and troubleshooting, particularly in settings where bandwidth requirements are critical.
