Hi Take,
It is great to hear from you on the 6lo list. Input from practical deployment is quite valuable especially if your organization is considering 6lo stack. There are couple of ways to contribute: 1) Providing suggested text on the draft and working with the co-authors and 6lo-chairs to update the document OR 2) Writing a separate short draft with the suggested texts or use-case scenarios which can be used as the input to the 6lo Applicability & usecase document I know we talked sometime ago off-line, if you have any further questions let me and Gabriel know.

We work with wireless, plc and rs485, knx, profibus, M-bus and what have you. This is my first post to an IETF mailinglist so please if someone wants to guide me on the proper way to submit parts of this if it is not totally bogus. The draft is a really nice oversight over 6lo in diverse use-cases, really nice as a quick reference on where to continue. We (modio) will probably make a flowchart thing based on this document and rfc6568 where you can put in your use-case and based on that get to know what could be appropriate 6lo-solutions instead of today's old standards and de facto standards. I am missing the following chapters, even though the standards are not there yet I feel it should be mentioned so they will not be forgotten. 6loPLC, now primarily G3-PLC and Prime, needs a chapter in 3.foo and 6.foo LPWAN on low frequency (somewhere between 60-600 Mhz). People are testing nowadays in Europe on the following available frequencies: -2.4GHz, crowded, short range, crowded, worldwide, crowded, poor penetration, crowded. -868 MHz, getting crowded, only 20kHz, poor hardware support. -433MHz (and in some countries other small bands between 398 - 465 MHz), long range, reliable, few channels, frequency allocations are specific to particular countries, 10kbit/s, still expensive modules. 27 and 40MHz HF, cheap, simple, long range, crowded, low data rates, crowded, large antennas needed For LPWAN to succeed we need more frequencies, both public ones and private ones booked through your local radio frequency authority. This should be named in the draft and also recommendations of what type of radio to run on these frequencies. It would be nice to state in this draft that in most part of the world 174-230 MHz VHF is more or less empty or run a very deprecated radio broadcasting standard which will probably be decommissioned during the next few years and that it would be nice to reserve a big part of it for IoT use, both public and bookable/buyable private channels. That would be the difference between happy go lucky LPWAN on existing channels and a worldwide break through for reliable serious applications LPWAN. 5 Design space: New bullet: Update firmware requirements: Most 6 lo uses case will need a mechanism for updating firmware. In these cases support for over the are updates are required, probably in a broadcast mode when bandwith is low and the number of identical devices is high. Security Requirements: (Actual text: Some 6lo use case can transfer some important and personal data between 6lo nodes. In this case, high-level security support is required.) 6lo will be used for important data between nodes, eventually someone will also know how to make today's not important data very important. High level security support is required. 6.4 use case of MS/TP I can probably write something there if interest exists. 6.6 use case of LTE MTC Mentions LTE MTC very briefly and then talks mostly about LoRa. Mayby change topic. Are you still with me? Regards, Take -- Take Aanstoot CEO Modio AB +254 70 646 2344 +46 13 46 555 62 [email protected] <mailto:[email protected]>
