The low- power variant of Bluetooth has been standardized since revision 4.0 of the Bluetooth specifications, although version 4.1 or newer is required for IPv6. This document describes how IPv6 is transported over Bluetooth low energy using IPv6 over Low-power Wireless Personal Area Network (6LoWPAN) techniques.
LoWPAN encapsulation as defined in RFC 4944 has been updated by [RFC6282], and may be extended and modified by future IETF Standards. The intended Layer 2 technology for IPv6 datagrams using LoWPAN encapsulation as originally defined is [IEEE.802.15.4_2011], which does not provide for a protocol switch in its Layer 2 headers.
As more and more protocols need to be compressed, the encoding capabilities of the original dispatch defined in the 6LowPAN adaptation-layer framework ([RFC4944] and [RFC6282]) becomes saturated. This specification introduces a new context switch mechanism for 6LoWPAN compression, expressed in terms of Pages and signaled by a new Paging Dispatch mechanism.
Master-Slave/Token-Passing (MS/TP) is a medium access control method for the RS-485 physical layer and is used primarily in building automation networks. This specification defines the frame format for transmission of IPv6 packets and the method of forming link-local and statelessly autoconfigured IPv6 addresses on MS/TP networks.
This standard specifies formats and methods for floating-point arithmetic in computer systems: standard and extended functions with single, double, extended, and extendable precision, and recommends formats for data interchange. Exception conditions are defined and standard handling of these conditions is specified.
This standard defines a protocol and procedures for the transport of timing over bridged and virtual bridged local area networks. It includes the transport of synchronized time, the selection of the timing source (i.e., best master), and the indication of the occurrence and magnitude of timing impairments (i.e., phase and frequency discontinuities).

This standard specifies how the MAC Service is supported by Virtual Bridged Local Area Networks, the principles of operation of those networks, and the operation of VLAN-aware Bridges, including management, protocols, and algorithms. Incorporates IEEE Std 802.1Q-2005, IEEE Std 802.1ad-2005, IEEE Std 802.1ak-2007, IEEE Std 802.1ag-2007, IEEE Std 802.1ah-2008, IEEE Std 802-1Q-2005/Cor-1-2008, IEEE Std 802.1ap-2008, IEEE Std 802.1Qaw-2009, IEEE Std 802.1Qay-2009, IEEE Std 802.1aj-2009, IEEE Std 802.1Qav-2009, IEEE Std Qau-2010, and IEEE Std Qat-2010.

A standardized framework for the Smart Appliances Reference Ontology based on the results of a European Commission Study Group on Smart Appliances ontologies and of a Specialist Task Force on the maintenance and evolution of the Reference Ontology taking into account all the interest of the relevant stakeholders.
The Internet of Things (IoT) is predicted to become one of the most significant drivers of growth in various technology markets. Most current standardization activities are confined to very specific verticals and represent islands of disjointed and often redundant development. The architectural framework defined in this standard will promote cross-domain interaction, aid system interoperability and functional compatibility, and further fuel the growth of the IoT market. The adoption of a unified approach to the development of IoT systems will reduce industry fragmentation and create a critical mass of multi-stakeholder activities around the world.
The frequency bands used for broadcasting below 30 MHz are: •Low Frequency (LF) band: from 148,5 kHz to 283,5 kHz, in ITU Region 1 [1] only; •Medium Frequency (MF) band: from 526,5 kHz to 1 606,5 kHz, in ITU Regions 1 [1] and 3 [1] and from 525 kHz to 1 705 kHz in ITU Region 2 [1]; •High Frequency (HF) band: a set of individual broadcasting bands in the frequency range 2,3 MHz to 27 MHz, generally available on a Worldwide basis. These bands offer unique propagation capabilities that permit the achievement of: •large coverage areas, whose size and location may be dependent upon the time of day, season of the year or period in the (approximately) 11 year sunspot cycle; •portable and mobile reception with relatively little impairment caused by the environment surrounding the receiver. There is thus a desire to continue broadcasting in these bands, perhaps especially in the case of international broadcasting where the HF bands offer the only reception possibilities which do not also involve the use of local repeater stations.
