47 CFR Appendix 1 to Subpart E of Part 95, Glossary of Terms
The definitions used in this subpart E are:
Authorized bandwidth. Maximum permissible bandwidth of a transmission.
Carrier power. Average TP during one unmodulated RF cycle.
CB. Citizens Band Radio Service.
CB transmitter. A transmitter that operates or is intended to operate at a station authorized in the CB.
Channel frequencies. Reference frequencies from which the carrier frequency, suppressed or otherwise, may not deviate by more than the specified frequency tolerance.
Crystal. Quartz piezo-electric element.
Crystal controlled. Use of a crystal to establish the transmitted frequency.
EIRP. Effective Isotropic Radiated Power. Antenna input power times gain for free-space or in-tissue measurement configurations required by MedRadio, expressed in watts, where the gain is referenced to an isotropic radiator.
FCC. Federal Communications Commission.
Filtering. Refers to the requirement in § 95.633(b).
FRS. Family Radio Service.
GMRS. General Mobile Radio Service.
GMRS transmitter. A transmitter that operates or is intended to operate at a station authorized in the GMRS.
Harmful interference. Any transmission, radiation or induction that endangers the functioning of a radionavigation or other safety service or seriously degrades, obstructs or repeatedly interrupts a radiocommunication service operating in accordance with applicable laws, treaties and regulations.
Mean power. TP averaged over at least 30 cycles of the lowest modulating frequency, typically 0.1 seconds at maximum power.
Medical Body Area Network (MBAN). An MBAN is a low power network consisting of a MedRadio programmer/control transmitter and one or more multiple medical body-worn devices all of which transmit or receive non-voice data or related device control commands for the purpose of measuring and recording physiological parameters and other patient information or performing diagnostic or therapeutic functions via radiated bi- or uni-directional electromagnetic signals.
Medical body-worn device. Apparatus that is placed on or in close proximity to the human body (e.g., within a few centimeters) for the purpose of performing diagnostic or therapeutic functions.
Medical body-worn transmitter. A MedRadio transmitter intended to be placed on or in close proximity to the human body (e.g., within a few centimeters) used to facilitate communications with other medical communications devices for purposes of delivering medical therapy to a patient or collecting medical diagnostic information from a patient.
Medical implant device. Apparatus that is placed inside the human body for the purpose of performing diagnostic or therapeutic functions.
Medical implant event. An occurrence or the lack of an occurrence recognized by a medical implant device, or a duly authorized health care professional, that requires the transmission of data from a medical implant transmitter in order to protect the safety or well-being of the person in whom the medical implant transmitter has been implanted.
Medical implant transmitter. A MedRadio transmitter in which both the antenna and transmitter device are designed to operate within a human body for the purpose of facilitating communications from a medical implant device.
Medical Micropower Network (MMN). An ultra-low power wideband network consisting of a MedRadio programmer/control transmitter and medical implant transmitters, all of which transmit or receive non-voice data or related device control commands for the purpose of facilitating functional electric stimulation, a technique using electric currents to activate and monitor nerves and muscles.
MedRadio programmer/control transmitter. A MedRadio transmitter that operates or is designed to operate outside of a human body for the purpose of communicating with a receiver, or for triggering a transmitter, connected to a medical implant device or to a medical body-worn device used in the MedRadio Service; and which also typically includes a frequency monitoring system that initiates a MedRadio communications session.
MedRadio Service. Medical Device Radiocommunication Service.
MedRadio transmitter. A transmitter authorized to operate in the MedRadio service.
MURS. Multi-Use Radio Service.
Peak envelope power. TP averaged during one RF cycle at the highest crest of the modulation envelope.
R/C. Radio Control Radio Service.
R/C transmitter. A transmitter that operates or is intended to operate at a station authorized in the R/C.
RF. Radio frequency.
TP. RF transmitter power expressed in W, either mean or peak envelope, as measured at the transmitter output antenna terminals.
Transmitter. Apparatus that converts electrical energy received from a source into RF energy capable of being radiated.
