802.11b is a wireless networking standard that was introduced in 1999 as part of the IEEE 802.11 family. It operates in the 2.4 GHz frequency band and supports data transfer rates of up to 11 Mbps. This standard was widely adopted for home and office networks due to its affordability and ease of use. One of the key features of 802.11b is its ability to provide a range of up to 150 feet indoors and up to 300 feet outdoors, depending on environmental conditions. However, it is susceptible to interference from other devices operating in the same frequency, such as microwaves and cordless phones.
