ETSI - EN 302 217-3 V1.3.1 (2009-07) Fixed Radio Systems; Characteristics and requirements for point-to-point equipment and antennas; 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: Graphical relationship among EIRP limitation, antenna gain and output power 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. Note: Pout max of +10 dBm only applies if Ga > 38 dBi 2a) EIRP density (dBm) ≤ -10 dBm/MHz + Gant (dBi). © Blu-Wireless Technology – CW 30 Jan 2014 © Blu-Wireless 2012 – Commercial in Confidence Page 14

  16. 16. 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! 31-Jan-14 © Blu-Wireless Technology – CW 30 Jan 2014 © Blu-Wireless 2012 – Commercial in Confidence Page 16
