base station
assembly of radio equipment consisting of at least a transmitter, receiver, and antenna connection at a fixed location
biotelemetry
transmission of physiologic data, such as an ECG, from the patient to a distant point of reception
closed-ended question
a question that is specific and focused, demanding either a yes or no answer or an answer chosen from specific options
digital radio
the microwave transmission of digital signal through space or the atmosphere instead of transmission by radiowaves
dispatch
to send to a specific destination or to send on a task
duplex
radio system using more than one frequency to permit simultaneous transmission and reception
emergency medical dispatch
first aid instructions given by specially trained dispatches to callers over the telephone while an ambulance is en route to the call
encoded
a message is put into a code before it is transmitted
enhanced 9-1-1 system
an emergency call-in system in which additional information such as the phone number and location of the caller is recorded automatically through sophisticated telephone and the dispatcher need only confirm the information on the screen
frequency
in radio communications the number of cycles per second of a signal; inversely related to the wavelength
hertz (Hz)
unit of frequency equal to 1 cycle per second
interpersonal communication
the exchange of information between two or more persons
landline
communications system linked by wires, usually in reference to a conventional telephone system
multiplex
method by which simultaneous transmission of voice and ECG signal can be achieved over a single radio frequency
open-ended question
a question that does not have a yes or no answer, and that does not give the patient specific options from which to choose
pervasive development disorders (PDD)
a group of disorders that cause delays in many areas of childhood development, such as the development of skills to communicate and interact socially, and may include repetitive body movements and difficulty with changes in routine
remote console
a terminal that receives transmissions of telemetry and voice from the field and transmits messages back, usually through the base station
Simplex
method of radio communication using a single frequency that enables transmission reception of voice of an ECG signal but is incapable of simultaneous transmission and reception
ten-code
a radio system using the number 10 plus another number
therapeutic communication
communicating with patient
transceiver
a radio transmitter and receiver housed in a single unit; a two-way radio
trunking
sharing of radio frequencies by multiple agencies or systems
ultrahigh frequency (UHF) band
the portion of the radio frequency spectrum between 300 - 3000 mHz
very high frequency (VHF) band
the portion of the radio frequency spectrum between 30 - 150 mHz
wavelength
the distance in a propagating wave from one point to the corresponding point on the next wave
