ETSI Defined RF Channels for DECT
DECT systems automatically select the best interference-free frequencies on which to operate. Users do not need to do any
frequency coordination. The ETSI (European Telecommunications Standards Institute) Channel Plan (Table 1) shows the
European and North American RF carrier pools the DECT systems use.
There are 10 frequencies in Europe and five frequencies in North America.
