Compared to alternatives like 802.11a and 802.11g, 802.11b network equipment costs less. Its relatively low cost naturally resulted in many home and small business networks adopting 802.11b. 802.11b LANs support a maximum data rate of 11 Mbps. Although 802.11b performs much better than traditional dial-up networking, the performance of 802.11b is still significantly less than 802.11a and other, newer standards.
