Hi Pascal. So basically you agree with my comments :=) Thanks, Patrick On 19/07/2017, 10:01, "Pascal Thubert (pthubert)" <pthubert@cisco.com> wrote: Hello Patrick: There is a match to be found between what Wi-Sun does and what LPWAN is chartered to cover. 1) It is good to mention as an overview that Wi-Sun FAN can do mesh, has routing and 6LoWPAN. It would be good to very briefly position the profiles and which of those qualify as LPWAN. OTOH, LPWAN is explicitly chartered outside of routing and 6LoWPAN, so there should not be too much emphasis on this since this is not what the LPWAN reader is after. What the LPWAN reader is after is the edge between the low power end objects and the first router, which appears like a LPWAN star. This is where an intersection with LPWAN technology is hopefully to be found. And then we can use the needs expressed in the overview to derive the next charter items. 2) is very close to 1). After a brief description of the mesh where routing happens, focus should move to access where LPWAN operates by charter.

First one: Paragraph 3. “Generic terminology”. This paragraph should take into account the WI-SUN architecture (as one of the technology in the scope). WI-SUN architecture introduces the notion of border router, routers and leaf nodes. WI-SUN is not talking about gateways, radio gateways etc. One way to solve this is to add another diagram with the WI-SUN approach. Second: Paragraph 4.6 says that no routing protocol is needed. This is not correct. WI-SUN is using RPL as routing protocol and is based on a mesh topology. This should be reflected in this paragraph not as a gap but as existing technology.

Title : LPWAN Overview Author : Stephen Farrell Filename : draft-ietf-lpwan-overview-05.txt Pages : 41 Date : 2017-07-01 Abstract: Low Power Wide Area Networks (LPWAN) are wireless technologies with characteristics such as large coverage areas, low bandwidth, possibly very small packet and application layer data sizes and long battery life operation. This memo is an informational overview of the set of LPWAN technologies being considered in the IETF and of the gaps that exist between the needs of those technologies and the goal of running IP in LPWANs.
