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.
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.
