Re: [Lwip] I-D Action: draft-ietf-lwig-energy-efficient-02.txt
Dear Dominique, Great, thanks a lot for your offer to provide the section on DECT-ULE! By the way, please let us know whether your request in Dallas to add text on the DSME mode of 15.4 would be satisfied by prepending the following text to the current last paragraph/sentence of 3.5.3: Another relevant 802.15.4e mode is the Deterministic and Synchronous Multi-channel Extension (DSME). This mode improves the CFP functionality in IEEE 802.15.4 by extending the number of time slots that can be reserved for contentionless data transmission, and allowing the use of frequency channel diversity (note that TSCH offers similar functionality). DSME also favors the formation of beacon-enabled multihop networks. DSME defines a structure by which the beacon interval comprises a number of multi-superframes. Each one of the latter comprises a number of superframes. Each superframe in DSME may contain a CAP interval and must contain at least one CFP interval. As in TSCH mode, during unscheduled CFP time slots, nodes may keep their radio in inactive mode to save energy. I believe once we add the text on DSME and the section on DECT-ULE, and after applying some further typo corrections, we will be ready for submitting a -03.

Re: [Lwip] 14.4e DSME ?
Dear Carles, From my reading of 15.4e-2012, I reckon the text you suggest on DSME is technically correct, and I second it. At the meeting in Dallas, I was also asking about the commercial significance of DSME. Does anybody know of equipment on the market today or under development that uses DSME? Just out of curiosity. I would think that those of this group that also go to 802.15 meetings would know who the forces behind DSME are, and what their intentions are. If we were to establish that DSME is not going to be used after all, at least not with an IP protocol stack, then adding the text that describes DSME in this draft would be a moot point.

Re: [Lwip] 15.4e DSME ?
+1 Let's see if anyone can provide a response to Dominique's question. Otherwise, I agree it would be better not to add the DSME text.
