IEEE802.11a
Wireless LAN standard that supports a maximum data rate of 54 Mbps. 802.11a devices operate in the 5 GHz lower
and middle UNII bands.
IEEE802.11b
Wireless LAN standard that supports a maximum data rate of 11 Mbps. 802.11b devices operate in the 2.4 GHz ISM
band.
IEEE802.11g
Wireless LAN standard that supports a maximum data rate of 54 Mbps. 802.11g devices operate in the 2.4 GHz ISM
band.
IEEE802.11n
Wireless LAN standard that supports a maximum data rate of up to 150 Mbps. 802.11n devices operate in the 2.4 and
5 GHz ISM bands.
Infrastructure
A name of a wireless LAN configuration. This type of communication uses an access point. Another type of
communication is called Ad Hoc.
IP Address
An identifier for a computer or device on a TCP/IP network. Networks using the TCP/IP protocol route messages based
on the IP address of the destination. The format of an IP address is a 32-bit numeric address written as four numbers
separated by periods. Each number can be zero to 255. For example, 1.160.10.240 could be an IP address.
Within an isolated network, you can assign IP addresses at random as long as each one is unique. However,
connecting a private network to the Internet requires using registered IP addresses (called Internet addresses) to
avoid duplicates.
The four numbers in an IP address are used in different ways to identify a particular network and a host on that
network. Three regional Internet registries -- ARIN, RIPE NCC and APNIC -- assign Internet addresses from the following
three classes.
