  • Harmonised European standard

ETSI EN 300 328 V2.2.2: wideband transmission systems; data transmission equipment operating in the 2.4 GHz band

  • ETSI Technical Committee ERM
  • European Telecommunications Standards Institute

Standards body (ETSI, the European Telecommunications Standards Institute)

Summary

The harmonised European standard for wideband data transmission equipment in the 2.4 GHz band, Bluetooth included; one voluntary way to show conformity with the EU Radio Equipment Directive.

Key findings

  • Limits RF output power to 20 dBm e.i.r.p., for frequency-hopping and other equipment alike.
  • Equipment that is not frequency hopping is also limited to a power spectral density of 10 dBm per MHz.
  • Non-adaptive equipment at 10 dBm e.i.r.p. or more is limited to a Medium Utilization factor of 10 % and to duty-cycle limits; these limits do not apply below 10 dBm.
  • Names Bluetooth wireless technologies among its examples of the equipment it covers.

Limits

Gives the limits used to show conformity, not the power a given product uses. Version 2.2.2, adopted 1 July 2019, was the latest in ETSI's archive when read.
