Encryption

the intended recipient.
Firewall

IEEE 802.11
A family of wireless network standards, which includes 802.11a, 802.11b,
802.11e, and 802.11g. The original 802.11 standard was first approved in 1997
but was not very successful because it was relatively slow at 2 Mbps.
IEEE 802.11b
A high-bit wireless network standard that works on the 2.4 GHz band, utilizes
DSSS (direct sequence spread spectrum) technology and specifies WEP encryption
for security. It offers data bit rates of up to 11 Mbps and the range is from 200 to
300 feet for maximum speed.
IEEE 802.11g
A new 802.11 standard for wireless networking hardware. The 802.11g standard
specifies a maximum data transfer rate of 54 Mbps, an operating frequency of 2.4
GHz, backward compatibility with 802.11b devices and WEP encryption for
security.
Infrastructure mode
A LAN or other small network mode in which wireless clients are part of the
network and use one or more access points to connect to a wired network. Each
access point is connected to the Ethernet network using a standard Ethernet cable.
In IEEE 802.11b specification, the infrastructure mode is referred to as the Basic
Service Set.
