Introduction of Wireless Router For ADSL
1.1
Introducing the Wireless Router For ADSL
Wireless Router For ADSL is a high performance wireless LAN access point
that complies with the IEEE 802.11b and 802.11g wireless standards, which can
be used to provide mobile clients with wireless access to an Ethernet network.
The Wireless Router For ADSL supports Windows XP, Windows 2000,
Windows Millennium Edition (ME), and Windows 98.
A wireless LAN provides the same functionality of a wired network, but it
eliminates the need to install networking cables and other networking equipment.
A wireless LAN is not only easier to deploy, but it also allows for mobility
through “roaming.” For example, the Wireless Router For ADSL can roam from a
conference room to an office without being disconnected from the network.

IEEE 802.11 Specifications
The Institute of Electrical and Electronics Engineers (IEEE) adopted the 802.11
standard for wireless devices operating in the 2.4 GHz frequency band in 1997.
This standard includes provisions for three radio technologies: direct sequence
spread spectrum, frequency hopping spread spectrum, and infrared. Devices that
comply with the 802.11
standard operate at a data rate of either 1 or 2 Mbps.
1.3.1
802.11b
In 1999, the IEEE modified the 802.11 standard to support direct sequence
devices that can operate at speeds of up to 11 Mbps. The IEEE ratified this
standard as
802.11b
. 802.11b devices are backwards compatible with 2.4 GHz
802.11 direct sequence devices (that operates at 1 or 2 Mbps).
1.3.2
802.11a
Also in 1999, the IEEE modified the 802.11 standard to support devices operating
in the 5 GHz frequency band. This standard is referred to as
802.11a
. 802.11a
devices are not backward compatible with 2.4 GHz 802.11 or 802.11b devices.
802.11a radios use a radio technology called Orthogonal Frequency Division
Multiplexing (OFDM) to achieve data rates of up to 54 Mbps.
1.3.3
802.11g
In 2003, the IEEE ratified the 802.11g standard. This standard delivers the same
54Mbps maximum data rate as 802.11a, yet it offers an additional and compelling
advantage-backward compatibility with 802.11b equipment. This means that
