C
CACT
CACT is an acronym for Channel Availability Check Time, a parameter used in
DFS channel selection. During DFS when a radio changes channels, it must
listen for the CACT on the new channel before beginning operations. For most
channels the CACT is 60 seconds.
Channel
One portion of the available radio spectrum that all devices on a wireless network
use to communicate. Changing the channel on the access point/router can help
reduce interference.
Channel Move Time
The maximum time a radio can take to transition to another channel when radar
is detected. Typically 10 seconds.
Client, Radio Mode
A radio in Client mode can connect to any Access Point, but can only support
one Ethernet device. See also Repeater, Radio Mode.
Client, Software
A client is a software program, or the device on which that program runs, that
makes requests for information from a software program, or the device on which
that program runs, in a client-server relationship.
A Client on an Ethernet network is equivalent to a Master on a serial network.
Configuration PC
A Computer that contains the configuration tools for the RLX2 radio series.
D
dBi
Decibels referenced to an "ideal" isotropic radiator in free space; frequently used
to express antenna gain
dBm
Decibels referenced to one milliwatt (mW); an "absolute" unit used to measure
signal power (transmit power output or received signal strength)
DCE
Data communications equipment. A modem, for example.
Decibel (dB)
A measure of the ratio between two signal levels; used to express gain (or loss)
in a system.
