802.11b Wireless LAN
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
to set-up and maintain.
well for home segment due to lower costs and simple set-up.
following are some of the disadvantages:
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.
operates in 2.4GHz frequency band, which is normally used by many
appliances. Hence, it is more interference prone compared to 802.11a.
provide suitable scalability required in business environment.
