Technical Summary


   The DECT Ultra Low Energy is an addition to the DECT interface
   primarily intended for low-bandwidth, low-power applications such as
   sensor devices, smart meters, home automation etc.  As the DECT Ultra
   Low Energy interface inherits many of the capabilities from DECT, it
   benefits from long range, interference free operation, world wide
   reserved frequency band, low silicon prices and maturity.  There is
   an added value in the ability to communicate with IPv6 over DECT ULE
   such as for Internet of Things applications. As an example, the technology could be
   integrated with residential gateway.
   DECT-ULE deployment typically use application profile based  protocol support and
   6lo-over-dect-ule is one of them. The differences between 6loWPAN(IPv6-over-IEEE802.15.4) and
   this specification are that DECT-ULE only supports Star topology, a 40-bit unique ID among DECT
   devices, optional MAC-48 bit assignment, larger MTU size than IEEE802.15.4 and thus different requirements
   for fragmentation and re-assembly. 
   The document also shows a mechansim for deriving the 64-bit IID in order to form an IPv6 address and
   subsets of RFC6775, Header compression.
   The draft discusses privacy considerations and possible randomly generated IID support.


Working Group Summary

  The document has been reviewed by several WG participants and the co-chairs. There were no contentious issues raised on the current version. 

Document Quality

The document has been reviewed over the 6lo WG mailing list (Kerry Lynn, Ralph Droms, Samita Chakrabarti,
Gabriel Montenegro) and the comments were addressed. A critical comment for the document was to remove
reference of globally unique 64-bit  IID when it is derived from 40bit DECT unique id, which was taken care
in version 05. The chairs have been informed that RTX and Gigaset have implementations on the draft. An open source
implementation might be available via ULE alliance.
