Carrier current systems have been around for many
years
Some examples:
Campus radio systems
Lamp/thermostat controllers
Until recently, general characteristics of carrier current
systems were:
Low frequency
Low speed
Narrow frequency/spectrum bands
Used inside buildings/controlled environments (campus)
February 16, 2005
3
 NEW Broadband over Power Lines (BPL) operations are
different
Advanced digital processing and modulation techniques
Multiple carriers
Wide spectrum bandwidths (e.g., 2-80 MHz)
 Two General Applications:
In-Home or in-building operations (HomePlug)
Access systems – Internet/broadband to neighborhood
using medium voltage lines
February 16, 2005
4
In-Home Computer Networking, Or
Link Between Access BPL & Home
“Low Voltage” (120/240 VAC)
Broadband Internet Service
“Medium Voltage” (e.g. 10kV)
Access BPL connects to
computers in the home by
in-house BPL or by WiFi (wireless)

Remove regulatory uncertainty to encourage
investments in BPL
Promote development of Access BPL
technology to allow consumers to reap its
benefits
Ensure protection of licensed radio services
Ensure that compliance measurements are made
in a consistent manner with repeatable results

 Access BPL remains under Part 15
unlicensed device rules (new Subpart G)
No change in existing Part 15 emission levels (low
power unlicensed operation)
Access BPL operations cannot cause harmful
interference and must accept any interference (47
C.F.R §15.5)
February 16, 2005
11
Access BPL must include adaptive
interference mitigation capabilities to
respond to local and site-specific
interference, e.g.
Exclude or “notch” any specific frequency or band
Remotely shut off any BPL device
February 16, 2005
12
BPL cannot operate on certain “excluded
frequency bands”
Specifically, the following 12 Aeronautical (R) frequencies
(communications restricted to safety and regularity of flight and
an ILS component):
2850-3025 kHz
3400-3500 kHz
4650-4700 kHz
5450-5680 kHz
6525-6685 kHz
8815-8965 kHz
10005-10100 kHz
11275-11400 kHz
13260-13360 kHz
17900-17970 kHz
21924-22000 kHz
74.8-75.2 MHz
February 16, 2005
13
Establishes “exclusion zones” within which
Access BPL must avoid operating on certain
frequencies
Access BPL must avoid using 2182 kHz (2173.5- 2190.5 kHz) within
1 km of a U.S. Coast Guard or maritime public coast station
Access BPL using overhead power lines must avoid using 73-74.6
MHz within 29 km of ten radio astronomy sites (Very Long Baseline
Array facilities)
Access BPL using underground power lines or overhead low voltage
power lines must avoid using 73-74.6 MHz within 11 km of certain
radio astronomy sites
February 16, 2005
14
Establishes “consultation requirements” for
BPL with public safety, and certain sensitive
federal and aeronautical stations
Establishes a “good faith” process to ensure
that
Access BPL systems do not cause interference;
and
Any restrictions by licensees on BPL are only those
necessary to avoid interference
February 16, 2005
15
Requires industry to establish a publicly
accessible database for Access BPL systems
containing:
Access BPL Provider Name
Access BPL deployment by zip code
Frequency bands of operation
Type of equipment (FCC ID)
Contact Information (phone number and email
address) to facilitate interference resolution
Proposed or Actual date of Access BPL operation
February 16, 2005
16
The industry will select the database
administrator and must inform the Commission
within 180 days of publication of Report and
Order in the Federal Register
The Commission will issue a Public Notice
announcing the identity of the database
administrator
February 16, 2005
17
Changes equipment authorization
requirements for Access BPL devices from
Verification to FCC Certification
Certification is an equipment authorization issued by
the FCC and requires manufacturers to submit testing
and measurement data to the FCC
Under Verification, the manufacturer determines the
equipment is compliant and no data is submitted to the
FCC unless requested

Provides new measurement procedures and
guidelines to ensure that testing of Access
BPL and other carrier current devices is
performed in a more consistent and
repeatable manner
Recommends that BPL operators perform
testing during initial installation and
periodically to ensure compliance

 Protection of Licensed Radio Services is provided by:
the emissions limits for Access BPL systems (low Part 15 levels)
the provisions for consultation areas, excluded bands, and exclusion
zones; and
the requirement that Access BPL systems not cause interference.
 The mitigation requirements are intended to ensure that
Access BPL systems are designed with features that
support interference mitigation
during initial installation, if sensitive local communications systems are
identified in advance; and
after installation, the newly required operational capabilities will allow
Access BPL system operators to expeditiously resolve any instances of
interference that may occur, without the need to cease operations and
thereby disrupt the broadband data services they provide to their
subscribers.
