repeater
Repeater that is shared by several user groups.
configuration file Consists of all the configuration settings needed for a base station, stored as
a file.
conventional
network
Systems that do not have centralized management of channel access. System
operation is entirely controlled by system end users.
CWID Continuous Wave Identification is a method of automatically identifying the
base station using a Morse code. Continuous wave means transmission of a
signal with a single frequency that is either on or off, as opposed to a
modulated carrier.
D
DAC Digital-to-Analog Converter. A device for converting a digital signal to an
analog signal that represents the same information.
DDC Digital Down Converter. A device which converts the digitized IF signal of
the receiver down to a lower frequency (complex baseband) to suit the DSP.
dispatcher A person who gives official instructions by radio to one or more SU users.
distributed voting Voting for the best RF signal that is carried out separately by each channel
group member using the same voting algorithm.
dotted quad A method for writing IPv4 addresses. The form is DDD.DDD.DDD.DDD
where DDD is an 8-bit decimal number.
downlink The transmission path from fixed equipment to SUs.
DSP Digital Signal Processor.
duplex Providing transmission and reception in both directions simultaneously.
duty cycle Used in relation to the PA, it is the proportion of time (expressed as a
percentage) during which the PA is transmitting.
