Glossary
triangular routing
The routing logic used for a mobile IP end device that has roamed to a
foreign network. Frames destined for a mobile end device are always sent
to the home subnet of the end device. If the end device has roamed to
another subnet, the frame must be forwarded to the remote subnet where
the end device currently resides.
unicast address
A unique Ethernet address assigned to a single device on the network.
VLAN (virtual LAN)
A network of wireless end devices that behave as if they are connected to
the same wire even though they may actually be physically located on
different segments of a local area network. You can group all wireless users
on a particular VLAN in order to manage the IP address space differently.
Or you can use VLANs to separate secure and non-secure traffic.
WAP (Wireless Access Point)
Also called a repeater. This access point does not have any connections on
its Ethernet port. It forwards data between the access point and the
secondary LAN.
WEP (Wired Equivalent Privacy) encryption
A feature that can be enabled in the radios that allows data encryption for
wireless communications. 802.1x security uses WEP encryption.
wireless bridge
Also called a point-to-point bridge. A wireless link that connects two wired
Ethernet segments. Two access points can be used to provide a wireless
bridge between two buildings, so that wired and wireless devices in each
building can communicate with devices in the other building.
wireless hop
A wireless link that occurs when data from a wireless end device moves
from one access point to another access point through the radio ports.
Using MobileLAN access products, Intermec recommends that your data
does not travel through more than three wireless hops.
Secure wireless hops are created when secure IAPP is enabled. Access
points use SWAP to authenticate each other.
