802.11g and b: 802.11g and 802.11b are wireless standards that communicate in
the 2.4 GHz band. 802.11g provides speeds up to 54 Mbps. 802.11b provides
speeds up to 11 Mbps.
Ad hoc network: A type of wireless network in which devices directly communicate
with each other rather than through a Wireless Access Point (WAP). Ad hoc networks
are typically small and simple (for example, two wireless PCs or a wireless PC and a
wireless printer). Performance on these types of networks can degrade if more than
six devices are on the network. Ad hoc networks are also known as “computer-to-
computer networks,” “peer-to-peer networks,” “independent basic service stations
(IBSS),” or “direct-connect wireless networks.”
Authentication: Authentication is a wireless network security strategy. On a network
with authentication, devices use a shared key as a password and communicate only
with devices that know the key. Unlike WEP, authentication does not encrypt the data
sent between wireless devices. However, authentication can be used in conjunction
with WEP. Authentication keys and WEP keys can be identical.
Channel: One of several pre-set frequencies at which 802.11-enabled devices
communicate in order to reduce interference. The number of channels available varies
by country/region.
Embedded Web server (EWS): The printer embedded Web server is a networking
configuration utility that is accessed through an Internet browser. For more
information, see “Embedded Web server (EWS)” on page 50.
Encryption: A network security strategy that encodes the data sent across a wireless
network making the data unintelligible to eavesdroppers. The printer supports WEP
and WPA.
Encryption keys: A sequence of characters or digits that a wireless device uses to
encode data. Encryption keys can be static (as they are in WEP) or dynamic (as they
are in WPA).
