10、ernational Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical,

11、operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in tur

12、n, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE

13、 In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e

14、.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not

15、suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTSITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the e

16、vidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had received notice of intellectual property, protected by patents, which ma

The Recommendation specifies sub 1 GHz TRXs which shall be interoperable with TRXs complying with Annex A of this Recommendation. 2 R

23、eferences None. 3 Definitions 3.1 Terms defined elsewhere None. 3.2 Terms defined in this Recommendation This Recommendation defines the following terms: 3.2.1 alien domain: Any group of non-ITU-T G.9959 nodes connected to the same or a different medium (wired or wireless). These domains can be used

24、 as backbones to the ITU-T G.9959 network or as separate networks. The bridging function to an alien domain, as well as coordination with an alien domain to avoid mutual interference is beyond the scope of this Recommendation. 3.2.2 broadcast: A type of communication where a node sends a MAC frame w

25、hich is simultaneously received by all other nodes within a direct range. In a multi-hop domain, some nodes of the domain may not receive the broadcast frame. 3.2.3 channel: A transmission path between nodes. Logically a channel is an instance of a communication medium being used for the purpose of

26、passing data between two or more nodes. 3.2.4 clear channel assessment (CCA): Provided by the receiver, a CCA indicates if the medium is busy, e.g., if a PHY frame is currently transmitted on the medium by another node. 3.2.5 data: Bits or bytes transported over the medium or via a reference point t

27、hat individually convey information. Data includes user (application) data and any other auxiliary information (overhead, control, management, etc.). Data does not include bits or bytes that, by themselves, do not convey any information, such as the preamble. 3.2.6 data rate: The rate, in bits per s

28、econd, at which data is transmitted by a node onto the medium. Data rate is calculated only for time periods of continuous transmission. 3.2.7 domain: A collection of ITU-T G.9959 nodes comprising the domain master and all those nodes that are registered with the same domain master. In the context o

29、f this Recommendation, use of the term domain without a qualifier means ITU-T G.9959 domain, and use of the term alien domain means non-ITU-T G.9959 domain. 3.2.8 domain ID: A unique identifier of a domain. Refer to HomeID. 3.2.9 domain master: A node with extended management capabilities which allo

30、ws it to handle registration and maintenance of the nodes in its domain. 3.2.10 home area network (HAN): A network capable of connecting devices in home premises. 2 Rec. ITU-T G.9959 (01/2015) 3.2.11 HomeID: Information unit used as a domain ID in ITU-T G.9959 networks. 3.2.12 inclusion: The process

31、 of adding a new node to a domain in a way so that the node can communicate with other nodes in the domain and filter out traffic from other domains. 3.2.13 inter-domain bridge (IDB): A bridging function to interconnect nodes of two different domains. 3.2.14 industrial, scientific and medical (ISM)

32、band: Frequency bands for industrial, scientific and medical use, allocated by the ITU. 3.2.15 latency: A measure of the delay from the instant that a frame has been transmitted through a reference point of the transmitter protocol stack to the instant when a frame reaches the corresponding referenc

33、e point of the receiver protocol stack. 3.2.16 logical (functional) interface: An interface in which the semantic, syntactic, and symbolic attributes of information flows are defined. Logical interfaces do not define the physical properties of signals used to represent the information. It is defined

34、 by a set of primitives. 3.2.17 medium: The radio waves carrying the signals. Walls and other building components may affect the quality of the medium. Nodes communicating via the same medium may interfere with each other. 3.2.18 multicast: A type of communication where a node sends a MAC frame whic

35、h is simultaneously received by one or more other nodes in the domain. 3.2.19 network: One or more, potentially overlapping, domains. 3.2.20 node: Any device that contains an ITU-T G.9959 transceiver. In the context of this Recommendation, the term node without a qualifier means an ITU-T G.9959 node

36、, and the term alien node means a non-ITU-T G.9959 node. 3.2.21 node ID: A unique identifier allocated to a node during its registration in a domain. 3.2.22 physical interface: An interface defined in terms of the physical properties of the signals used to represent the information transfer. A physi

37、cal interface is defined by signal parameters like power (power spectrum density) and timing. 3.2.23 primitives: Variables and functions used to define logical interfaces and reference points. 3.2.24 reference point: A location in a signal flow, either logical or physical, that provides a common poi

38、nt for observation and or measurement of the signal flow. 3.2.25 symbol frame: A frame composed of bits of a single modulation symbol period. 3.2.26 symbol rate: The rate, in symbols per second, at which modulation symbols are transmitted by a node onto a medium. Symbol rate is calculated only for t

39、ime periods of continuous transmission. 3.2.27 transmission overhead: A part of the available data rate used to support transmission over the media (e.g., preamble, inter-frame gaps, and silent periods). 3.2.28 unicast: A type of communication when a node sends the frame to another single node.

46、rinciples of ITU-T G.9959 networking The following are the basic principles of the ITU-T G.9959 network architecture: 1. The network is divided into domains: The division of physical nodes into domains is logical. Domains may fully or partially overlap as there is no physical separation. The number

47、of domains is limited by the 32-bit HomeID identifier. Each domain is identified by a unique HomeID. Nodes of different domains may communicate with each other via inter-domain bridges (IDB). Rec. ITU-T G.9959 (01/2015) 5 Operation of different domains is handled by individual domain masters. 2. The

48、 domain is a set of nodes connected to the same medium: One node in the domain operates as a domain master. Each domain may contain up to 232 nodes (including the domain master). Each node in the domain is identified by a NodeID that is unique inside the domain. All nodes that belong to the same dom

49、ain are identified by the same HomeID. A node can belong to only one domain. Nodes of the same domain may communicate with each other either directly or via other nodes of the same domain. 3. Nodes of different ITU-T G.9959 domains: Nodes in different domains can communicate via IDB. The IDB function is a bridging function associated with one dedicated node in each network domain.
