Responses to Spectrum Commons Classes for Licence-Exemption

The responses to the Spectrum Commons Classes for Licence-Exemption consultation are now available on the site of the UK regulator Ofcom.

The RSGB Reposnse can be seen at:

Among the points it makes are:

"Levels of -80dBm/MHz would represent a serious level of interference for receivers used by our members and other licensed services. We note that even the emission mask for UWB includes -85 or -90dBm/MHz levels to protect key services. Lower levels still would be desirable along with a definition that accounted for exempt device eirp, as opposed to just transmitter powers."

"As per our input to the previous Ofcom-LEFR consultation, we have little faith in the effectiveness of current LBT/DAA mitigation techniques as generally they will not deal with 'hidden terminals'. The techniques are also likely to be undermined by poorer antenna/receiver performance than that used by licensed services."

Details of the consultation, which could increase the noise floor, are available at http://www.ofcom.org.uk/consult/condocs/scc/
