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 environment.
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
environment.
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 messages 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 network 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 OfficeConnect range support auto-negotiation.
Auto-negotiation is where two devices sharing a link, automatically
