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.

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 30inJan 2014 © Blu-Wireless 2012 – Commercial Confidence Page 16 Thank you For further information please visit www.bluwirelesstechnology.com or contact [email protected] 31-Jan-14 © Blu-Wireless Technology – CW 30inJan 2014 © Blu-Wireless 2012 – Commercial Confidence Page 17
