Glossary
802.11b
The IEEE specification for wireless Ethernet which allows speeds of up to 11 Mbps. The standard provides
for 1, 2, 5.5 and 11 Mbps data rates. The rates will switch automatically depending on range and environ-
ment.
802.11g
The IEEE specification for wireless Ethernet which allows speeds of up to 54 Mbps. The standard provides
for 6, 12, 24, 36, 48 and 54 Mbps data rates. The rates will switch automatically depending on range and en-
vironment.
802.11n
The IEEE specification for wireless Ethernet which allows speeds of up to 100 Mbps.
10BASE-T
The IEEE specification for 10 Mbps Ethernet over Category 3, 4 or 5 twisted pair cable.
100BASE-TX
The IEEE specification for 100 Mbps Fast Ethernet over Category 5 twisted-pair cable.
Access Point
An Access Point is a device through which wireless clients connect to other wireless clients and which acts
as a bridge between wireless clients and a wired network, such as Ethernet. Wireless clients can be moved
anywhere within the coverage area of the access point and still connect with each other. If connected to an
Ethernet network, the access point monitors Ethernet traffic and forwards appropriate Ethernet messages to
the wireless network, while also monitoring wireless client radio traffic and forwarding wireless client mes-
sages to the Ethernet LAN.
Ad Hoc mode
Ad Hoc mode is a configuration supported by most wireless clients. It is used to connect a peer to peer net-
work together without the use of an access point. It offers lower performance than infrastructure mode, which
is the mode the router uses. (see also Infrastructure mode.
Auto-negotiation
Some devices in the range support auto-negotiation. Auto-negotiation is where two devices sharing a link,
automatically configure to use the best common speed. The order of preference (best first) is: 100BASE-TX
