Ray, Could you elaborate on this point: Ø What I don't want to see is that break _within_ the band getting conflated with breaks _between_ bands.
This is the only issue which we do not have consensus and prevents the editor to submit an updated version of the draft. We do seem to have consensus that the current encoding in the draft has to be updated, as with the current encoding it is not possible to specify the power levels for unavailable ranges. What we do not have consensus on is on the options below: - Option 1: List of (startHz, startPower, stopHz, stopPower) - Option 2: Ordered list of (freqHz, power) So far we have few people speaking for either of the options. We need to agree on this asap and move forward, so please send a mail to the list and indicate whether you are ok with either option, or you feel strongly for one or the other. - gabor From: [email protected] [mailto:[email protected]] On Behalf Of ext Ray Bellis Sent: Tuesday, September 17, 2013 2:08 AM To: Paul Lambert Cc: [email protected] Subject: Re: [paws] Encoding of spectrum profile On 17 Sep 2013, at 09:33, Paul Lambert <[email protected]<mailto:[email protected]>> wrote: Yes - I feel it's important to retain a definition and identification of the channels. Can you elaborate on why you feel that's important? Why does a device "care" about the fact that the US TV band is split into four discrete bands - surely all that matters is the specific frequencies it's permitted to use? I may not be fully understanding your notion of a discontinuity within a band. I'd typically assume that system need well defined channels within a band that each could be also given masks that might vary depending on adjacency considerations. In the OFCOM model channel 38 will not be available for _primary_ transmission, but AIUI a very small amount of adjacent channel leakage into it will be permitted. The OFCOM / ETSI model doesn't need (or want) masks to be encoded within the messages for that channel, they're implicit in the device approval requirements. To further reduce the adjacent channel leakage the permitted power levels (for certain WSD emission classes) for primary transmissions in the adjacent channels are also reduced. That frequency is therefore simply omitted from the list of available channels. What I don't want to see is that break _within_ the band getting conflated with breaks _between_ bands. Ray
