host equipment: host equipment is any equipment which has complete user functionality when not connected to the

radio equipment part and to which the radio equipment part provides additional functionality and to which connection is

necessary for the radio equipment part to offer functionality

Idle Period: period in time following a transmission sequence during which the equipment does not transmit

integral antenna: antenna designed as a fixed part of the equipment, without the use of an external connector and

which cannot be disconnected from the equipment by a user with the intent to connect another antenna

NOTE: An integral antenna may be fitted internally or externally. In the case where the antenna is external, a

non-detachable cable may be used.

Listen Before Talk (LBT): mechanism by which an equipment first applies CCA before using the channel

load based equipment: equipment where, opposite to a frame based equipment, the transmit/receive structure is

demand-driven

multi-radio equipment: radio, host or combined equipment using more than one radio transceiver

medical device: any instrument, apparatus, appliance, software, material or other article, whether used alone or in

combination, together with any accessories, including the software intended by its manufacturer to be used specifically

for diagnostic and/or therapeutic purposes and necessary for its proper application, intended by the manufacturer to be

used for human beings for the purpose of:

• diagnosis, prevention, monitoring, treatment or alleviation of disease,

• diagnosis, monitoring, treatment, alleviation of or compensation for an injury or handicap,

• investigation, replacement or modification of the anatomy or of a physiological process,

• control of conception,

and which does not achieve its principal intended action in or on the human body by pharmacological, immunological

or metabolic means, but which may be assisted in its function by such means

necessary bandwidth: width of the frequency band which is just sufficient to ensure the transmission of information at

the rate and with the quality required under specified conditions

operating frequency: nominal frequency at which the equipment can be operated; this is also referred to as the

operating centre frequency

NOTE: Equipment may be adjustable for operation at more than one operating frequency.

out-of-band emission: emission on a frequency or frequencies immediately outside the necessary bandwidth which

results from the modulation process, but excluding emissions in the spurious domain

plug-in radio equipment: radio equipment module intended to be used with or within host, combined or multi-radio

equipment, using their control functions and power supply

power envelope: frequency/power contour within which the useful RF power is generated

receive chain: receiver circuit with an associated antenna

NOTE: Two or more receive chains are combined in a smart antenna system.

smart antenna systems: equipment that combines multiple transmit and/or receive chains with a signal processing

function to increase the throughput and/or to optimize its radiation and/or reception capabilities

NOTE: E.g. techniques such as spatial multiplexing, beamforming, cyclic delay diversity, MIMO, etc.

spurious emissions: emissions on a frequency or frequencies which are outside the necessary bandwidth and the level

of which may be reduced without affecting the corresponding transmission of information

NOTE: Spurious emissions include harmonic emissions, parasitic emissions, intermodulation products and

frequency conversion products, but exclude out-of-band emissions.
