lpwan S. Farrell, Ed. Internet-Draft Trinity College Dublin Intended status: Informational October 23, 2016 Expires: April 26, 2017 LPWAN Overview draft-farrell-lpwan-overview-00 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.

Introduction [[Editor comments/queries are in double square brackets like this.]] This document provides background material and an overview of the technologies being considered in the IETF's Low Power Wide-Area Networking (LPWAN) working group. We also provide a gap analysis between the needs of these technologies and currently available IETF specifications. This document is largely the work of the people listed in Section 8. Discussion of this document should take place on the lpwan@ietf.org list. [[Editor's note: the eventual fate of this draft is a topic for the WG to consider - it might end up as a useful RFC, or it might be best maintained as a draft only until its utility has dissapated. FWIW, the editor doesn't mind what outcome the WG choose.]] 2. Terminology [[Not sure if 2119 terms will be needed. Leave it here for now.]] The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 [RFC2119]. Farrell Expires April 26, 2017 [Page 2] Internet-Draft Low Power Wide Area Networking Overview October 2016 [[Extract common terms here. Maybe define and relate technology specific terms, e.g. lora g/w similar to sigfox bs etc. There is text for this in the current "gaps" draft.]] 3. Common Concerns [[Editors note: We may want a section like this that describes some cross-cutting issues, e.g. duty-cycles, some of the ISM band restrictions. This isn't intended to be a problem statement nor a set of requirements but just to describe some issues that affect more than one of the LPWAN technologies. Such a section might be better before or after Section 4, will see when text's added there. There is some text for this in the current "gaps" draft.]] 4. LPWAN Technologies This section provides an overview of the set of LPWAN technologies that are being considered in the LPWAN working group. The text for each was mainly contributed by the proponents of each technology. Note that this text is not intended to be normative in any sesne, but simply to help the reader in finding the relevant layer 2 specifications and in understanding how those integrate with IETF- defined technologies. Similarly, there is no attempt here to set out the pros and cons of the relevant technologies. [[Editor: I assume that's the right target here. Please comment if you disagree.]] [[Editor's note: the goal here is 2-3 pages per technology. If there's much more needed then we could add appendices I guess depending on what text the WG find useful to include.]] 4.1. LoRaWAN [[Text TBD, I-D co-authored by the editor of this document and Alper is planned to be published Wed Oct 26]] 4.2. Narrowband IoT (nb-iot) [[Add text here from [I-D.ratilainen-lpwan-nb-iot].]] 4.3. Sigfox [[Add text here from [I-D.zuniga-lpwan-sigfox-system-description].]] Farrell Expires April 26, 2017 [Page 3] Internet-Draft Low Power Wide Area Networking Overview October 2016 4.4. WI-SUN [[Add text here when available. Source = bheile@ieee.org]] 5. Gap Analysis [[Add text here from [I-D.minaburo-lpwan-gap-analysis].]] 6. Security Considerations 7.
