Glossary
WEP (Wired Equivalent Privacy) encryption
A feature that can be enabled in the IEEE 802.11b or 802.11a radio that
allows data encryption for wireless communications.
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.
