Appendix A

Agrees.  It considers that the proposed European framework represents a manageable level of interference risk in respect to Telecom DMR technologies operating in the bands concerned. It suggests establishing an aggregate interference limit for UWB devices of 10 dB below the thermal noise of licensed receivers.

Agrees. It acknowledges the ongoing review nature of the standard and suggests adopting the latest revision. It also suggests emphasising measures to control non compliant products and establishing appropriated product certification.

Suggests strengthening product compliance and product certification processes in order to prevent the risk of interference from non compliant products.

Agrees. It suggests applying the EU proposed power limit levels post 2010 from day one, without following the EU transitional period prior 2010. Suggests clarifying the difference between the EU limit levels prior (transitional) and post 2010 in terms of the proposed EU spectral mask. It recommends further investigating performance protection aspects of digital microwave links in specific bands.

Suggests considering operational control measures in the GUL that can help minimising the risk of harmful interference to fixed links.

Suggests adding detail to the proposal by means of making reference to the ECC emission limits table (fig.4) It also suggests stating that the ECC emission mask represents maximum power levels (fig.3)
