RLX2 Industrial Hotspot Series
Configuration PC
A Computer that is used to configure the RLX2 radio series using any of the RLX2
configuration interfaces.
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.
Default Gateway
The IP address of a network router where data is sent if the destination IP address is
outside the local subnet. The gateway is the device that routes the traffic from the local
area network to other networks such as the Internet.
Device-to-Device Network (Peer-to-Peer Network)
Two or more devices that connect using wireless network devices without the use of a
centralized wireless access point. Also known as a peer-to-peer network.
DFS
DFS stands for Dynamic Frequency Selection, a requirement for operation on certain
frequencies in the 5 GHz band in many countries. When a radio operates on a DFS
frequency, it must sense the presence of radar and automatically change to another
channel if radar is detected.
DHCP
The dynamic host configuration protocol is an Internet protocol, similar to BootP, for
automating the configuration of computers that use TCP/IP. DHCP can be used to
automatically assign IP addresses, to deliver IP stack configuration parameters, such as
