The IESG has received a request from the Light-Weight Implementation Guidance WG (lwig) to consider the following document: - 'Building Power-Efficient CoAP Devices for Cellular Networks' <draft-ietf-lwig-cellular-04.txt> as Informational RFC The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2015-08-24. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract This memo discusses the use of the Constrained Application Protocol (CoAP) protocol in building sensors and other devices that employ cellular networks as a communications medium. Building communicating devices that employ these networks is obviously well known, but this memo focuses specifically on techniques necessary to minimize power consumption. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-lwig-cellular/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-lwig-cellular/ballot/ No IPR declarations have been submitted directly on this I-D.
