point-to-point bridge

See also wireless bridge. A bridge that connects two wired networks with similar architectures. Two access points can be used to provide a point-to- point bridge between two buildings so that wired and wireless devices in each building can communicate with devices in the other building.

power bridge

A power bridge combines power and data onto an Ethernet cable that is connected to the access point with the power over Ethernet option.

primary bridging

Ethernet bridging on a root port. An access point uses primary bridging to bridge frames to and from the Ethernet network on its root port. Note that primary bridging is not the same as bridging to the primary LAN.

primary LAN

Also called the home IP subnet and root IP subnet. The IP subnet that contains the root access point. The primary LAN is typically the LAN on which the servers are located.

QFSK (Quad Frequency Shift Key)

A broadcasting method that shortens the range but doubles the throughput as compared to the BFSK method. In access points using a 2.4 GHz OpenAir radio, the radio can automatically switch between QFSK and BFSK as needed if the transmit mode is set to AUTO.

remote IP subnet

An IP subnet that is separated from the primary IP subnet (primary LAN) by a router. Remote IP subnets communicate with the primary LAN through IP tunnels. A remote IP subnet is a type of secondary LAN.

root access point

The access point with the highest root priority becomes the root of the network spanning tree. If the root becomes inactive, the remaining root candidates negotiate to determine which access point becomes the new root. The root can be used to set system-wide flooding and RF parameters. The root is also the only node in the network that can originate IP tunnels.
