What radiated power limits apply to devices operating in the 2.4 GHz band?
For operation of devices under the LIPD class licence a maximum radiated power of: • four watts EIRP is authorised in the 2.4 – 2.4835 GHz band for digital modulation transmitters • 500 milliwatts EIRP is authorised in the 2.4 – 2.4835 GHz band for frequency hopping transmitters that use a minimum of 15 hopping frequencies • four watts EIRP is authorised in the 2.4 – 2.4835 GHz band for frequency hopping transmitters that use a minimum of 75 hopping frequencies • one watt EIRP is authorised in the 2.4 – 2.45 GHz band for telecommand and telemetry transmitters and radiofrequency identification transmitters • 10 milliwatts EIRP is authorised in the 2.4 – 2.4835 GHz band for all other transmitters In addition the LIPD class licence and associated Short Range Devices (SRD) standard include power spectral density limits that must be complied with.
