stand-alone radio equipment: equipment that is intended primarily as communications equipment and that is normally
used on a stand-alone basis
supplier: person or entity submitting the equipment for testing
transmit chain: transmitter circuit with an associated antenna
NOTE: Two or more transmit chains are combined in a smart antenna system.
ultra wide band technology: technology for short-range radiocommunication, involving the intentional generation and
transmission of radio-frequency energy that spreads over a very large frequency range, which may overlap several
frequency bands allocated to radiocommunication services
wide band modulation: wide band modulation is considered to include FHSS, DSSS, OFDM, etc. that meet the
emission requirements as defined in the present document
