ETSI - EN 302 217-3 V1.3.1 (2009-07)
UBa.2.1 Transmitter power, antenna gain and Equivalent
Isotropically Radiated Power (EIRP)
The following transmitter output power, antenna gain and EIRP limits
are set by CEPT/ECC/Recommendation 09-01 [4]:
• Maximum EIRP: +55 dBm.
• Minimum antenna gain: +30 dBi.
• Maximum transmitter output power: +10 dBm.
In addition, in order of safeguarding a fair and efficient use of the
spectrum, emissions of equipment in the scope of the present
document shall be further limited as follows:
1a) EIRP (dBm)
≤ 55 for Gant ≥ 45 dBi.
≤ +10 + Gant (dBi) for 45 dBi > Gant ≥ 38 dBi.
≤ -28 + 2 * Gant (dBi) for 38 dBi > Gant ≥ 30 dBi.
2a) EIRP density (dBm)
≤ -10 dBm/MHz + Gant (dBi).

Note: Pout max of +10 dBm only applies if Ga > 38 dBi

Summary
� 60 GHz wireless technology can deliver significant cost
reduction for wireless backhaul
� Current EU radio regulations do not allow direct
deployment of phased array technology for backhaul
� Outdoor operation of WiGig CE devices will already
violate EU CEPT REC(09)01 rules so why constrain
application of phased array technology for backhaul?
� Urgent need to review and harmonise EU 60 GHz radio
regulations with US to stimulate deployment of low
cost 60GHz wireless backhaul in Europe!
