802.11b Wireless LAN Protocol Features
The first wireless LAN (WLAN) standard was created by
the IEEE committee in 1997, and was called 802.11. However,
802.11 standard supported only up to 2 Mbps of bandwidth,
and quickly became obsolete. Subsequently, IEEE created
the 802.11a, and 802.11b standards.
The following are the advantages of the IEEE 802.11b
standard compared to 802.11a and Bluetooth wireless LAN:
- The 802.11b WLAN standard is widely supported by
manufacturers, and very cost effective.
- Easy to set-up and maintain.
- Suits well for home segment due to lower costs and
The following are some of the disadvantages:
- Supports only up to 11Mbps bandwidth. Though the
speed is sufficient for most applications, it limits
the number of simultaneous users to a far less number
compared to 802.11a.
- It operates in 2.4GHz frequency band, which is normally
used by many appliances. Hence, it is more interference
prone compared to 802.11a.
- Doesn't provide suitable scalability required in
