Re: [lp-wan] Focused Scope for LPWAN WG at Berlin

Hello Thomas:

The sense of the room and the talks in the corridors made very clear (to me) that there were elephants (and maybe one mammoth) in the room. At the top of the rumor, we found LoRa, SigFox and 802.15.4g. To progress, we need contacts (cross participation, intent messaging from responsible entities), we must identify deliverables that make sense for the IETF (feasibility in due time), and critical mass of people (we seem to have it for identified candidate items).

My perception so far:

-        LoRa: we have an organization to talk to, LoRaWAN; we have not determined yet if and on which topic there is a shared desire to get work done at the IETF

-        802.15.4g: we also have a clear partner organization, and we are used to work together. What is less clear is the issues that this technology has in common with other LPWA networks, and which PHYs would be considered

-        SigFox: we found a common interest, but the exact topics need to be refined before Berlin. It is unclear (to me) if we have a peer organization to talk to and how the adoption of IETF work will happen.

There is also the question of whether the work we do would be of interest for NB-IOT: there was little hope that a consistent sense would emerge between now and Berlin that NB-IOT is willing to consider adopting, say, a new compression technique as an update/replacement to ROHC.

Cheers,

Pascal

I believe the BoF at Buenos Aires indicated work needs to be done in the area of LPWAN at the IETF.

Most of the discussion in Buenos Aires was about the technology that was going to be addressed; that discussion is missing from the initial e-mail in this thread.

There was a clear consensus from the room to narrow the scope of LPWAN to 2-3 long-range technologies. There were some remarks about whether this was the LPWAN group pushing new technology, or whether there was pull from the entities defining that technology. Since then, representatives of companies working on SIGFOX and IEEE802.15.4g technology spoke up, expressing clear interest for the solutions LPWAN could come up with. There may be others speaking up.

So I believe we have our 2-3 technologies, and I strongly suggest the LPWAN group narrows its scope to those as an initial set. Please note that a IEEE802.15.4g network is not per-se single hop, so that "feature" of LPWAN should be lifted.

My 2c.

Thomas

Hi Ana,

I would focus on the use of IPv6 over these low power wide area networks.

Device management approaches, OMA LWM2M, COMI/COOL or others, would work over these radio technologies.

For security I haven’t seen a document that convinced me that some work is needed.

Ciao
Hannes

Subject: [lp-wan] Focused Scope for LPWAN WG at Berlin

Hello again,

Well in this message I would like to discuss the scope of the WG. We need to define the focused gaps we want to work in. Let's agree about which are the subjects we want to study,

I think the following points are vey important in order to create the WG, please tell me which other you think we need to add.

1. IPv6
draft-gomez-lpwan-ipv6-analysis-00
IP End to End Communication
IPv6 MTU requires fragmentation
ND will be configured in advanced

2. Header Compression
draft-toutain-lp-wan-compression-context-00
New Mechanism adapted to challenged networks

3.  Security
Personal information need to be secured,

4. Management
draft-pelov-core-cosol-01
draft-veillette-core-cool-01
draft-somaraju-core-sid-00

Regards
Ana
