Abstract This document interprets the European standard ETSI EN 300 220-1 V2.3.1. It
is included that the choice of model for testing and test conditions. Moreover, the
transmitter requirements (frequency error, conducted average power, effective
radiated power,spread spectrum modulation,transient power,adjacent channel power
modulation bandwidth, spurious emission, frequency stability, duty cycle, etc) and
receiver requirements (sensitivity, LBT threshold, adjacent power selectivity, blocking
spurious response rejection,spurious emission,etc)are also explained comprehensively
Finally, there are also illustrations on the test layout and methods in the anechoic
chamber, semi anechoic chamber and open area test sites.
Keywords short range devices; spread spectrum modulation; spurious emission;
sensitivity
