Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are
members of ISO or IEC participate in the development of International Standards through technical
committees established by the respective organization to deal with particular fields of technical
activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international
organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the
work. In the field of information technology, ISO and IEC have established a joint technical committee,
ISO/IEC JTC 1.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives,
Part 2.
The main task of the joint technical committee is to prepare International Standards. Draft International
Standards adopted by the joint technical committee are circulated to national bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the national bodies
casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
ISO/IEC 12139-1 was prepared by Korean Agency for Technology and Standards (as KS X 4600-1)
and was adopted, under a special “fast-track procedure”, by Joint Technical Committee
ISO/IEC JTC 1, Information technology, in parallel with its approval by the national bodies of ISO and
IEC.
ISO/IEC 12139 consists of the following parts, under the general title Information technology —
Telecommunications and information exchange between systems — Powerline communication
(PLC) — High speed PLC medium access control (MAC) and physical layer (PHY):
⎯ Part 1: General requirements
Advanced MAC and PHY requirements will form the subject of a future Part 2.
Part 1 covers MAC and PHY technology for In-home/Access data networks via powerline
communications (PLC), the system of which is operating below 30MHz. The coexistence schemes will
be considered in developing Part 2, which will apply to data and high quality multimedia networks
requiring advanced MAC and PHY technology. The used or forbidden band of this standard will be
subject to national regulations.

5 Reference Models
High speed PLC refers to interactive communication between more than two PLC devices in in-home
or access network by using low and medium voltage powerline. Each PLC device can communicate
with other PLC devices with the same group identifier as itself, and can communicate in various
manners by forming a single logical network with them.
5.1 PLC Reference Model
Reference model of a high speed PLC system is constituted as in Fig. 1.
MI PI PI MI
Power Line
MAC/PHY MAC/PHY
STA STA
Fig. 1 - PLC Reference Model
PHY Interface (PI) is the physical interface between STA and the powerline. MAC Interface (MI) is the
logical interface defining the relationship between the upper link layer and MAC layer of STA. The
device including MAC and PHY, which are defined in this standard, is referred to as STA.
5.2 Interface Protocol Reference Model
Interface protocol reference model, illustrated in Fig. 2, is another expression of reference model and
emphasizing the layer structure. The "upper layer" in this standard refers to the link layer above MI.

only. STAs of each home shall form a cell (logical network) through GID. Each cell co-exists on the
same physical network, but they shall be logically separated. Privacy shall be guaranteed by
encoding data using different encryption keys. STAs of each cell render ad-hoc network and access

---------------------- Page: 13 ----------------------
ISO/IEC 12139-1:2009(E)
STA functioning as the connection point with the backbone network in the access network is located
on neighborhood transformer and thereby renders it possible for STAs existing in the same physical
network to form a high speed access network.
Cell Bridge (CB), which is STA connecting two separate cells (two logical networks), makes it possible
for the STAs at home to access a high speed access network. CB also functions as the repeater
extending the communication coverage.
STAs composing in-home network can access a high speed access network through home networking
and CB.

a bandwidth of 97.65625kHZ (theoretical) with the exception of the bandwidth designated as the guard
band in accordance with each national regulation. The cyclic prefix of 128 samples shall be used in
order to remove interference between DMT symbols in powerline channels. In addition, in order to
